OPPO K9 (8GB/128GB/All Netcom/5G Version) Comments

The new machine is equipped with 65W super flash charge, which is also the further popularization of OPPO hard core technology. OPPO K9 mobile phone has been double optimized in terms of bottom structure and motherboard layout, achieving a body thickness of 8.0mm and a weight of about 172g, which is quite comfortable to hold. Of course, the new machine is also equipped with Snapdragon 768G chip, 64 million pixel ultra clear three camera and 90Hz high screen, with balanced overall configuration.

Photo quality is average

OPPO K9 mobile phone supports 65W super flash charge, which is the further popularization of OPPO hard core technology.

The brightness of the screen is very good. The brightness is very suitable for playing outdoors. The 180Hz touch sampling operation is silky and smooth. I'm not used to fingerprints under the screen. More and more, colorful colorful shells are really dazzling, and individuals are purists. I feel that the camera is still good. After all, I call for a camera phone every day.

I think it would be better if prices were lower. Can be used as a spare game console

The first thing that attracted me about the K9 was its appearance. The one I bought was black. There were letters and numbers on the back of the K9. There were two English words "super performance" on it, which meant super performance. This shows how confident OPPO is about this K9. I think this is the selling point of the phone. The black background on the back and the letters inside need to be slightly turned to the side of the body so that the reflective effect can be seen with polarized light. It looks grand, has a sense of technology, and also has a sense of mystery. Its camera lineup is a combination of 64 million pixels+8 million pixels+2 million pixels, from which we can see that its photography is very good. After my actual measurement, I like every scene taken, whether it's people, scenery or food. In particular, OPPO's color mixing style is very consistent with my aesthetic, warm, not cold and white, I feel a sense of distance when I look at it. Moreover, its overall photographic performance is also very good. When summer comes, we can use it to meet all our photographic needs when traveling with friends. We are not afraid to take bad photos when we are late with friends, because it has its own night view mode, which can outline the overall outline very finely even at night, The only difference between the night view mode and the main shooting mode is that its photography speed is slow, which should be analyzed. So every time I press the shutter, it will rotate once before saving, but I think the saved picture is pretty good. In addition to taking pictures, the phone also supports super double anti shake, which is mainly used to solve some shake problems that may be encountered in ordinary times. It is very friendly to some people who like to take videos, and solves the problem of unclear pictures caused by taking pictures while walking. The last thing to say is that it has 65W super flash charge, which can be said that its competitiveness among mobile phones at the same price has risen in a straight line, refreshing my understanding of 1000 yuan mobile phones. I have to say that 65W is cool to use, charging for half an hour, and lasting a whole day.

The performance is good, and the game is very enjoyable. However, the battery capacity of the phone is average. The phone is a dual mode 5G phone, and the screen refresh rate of the phone is still 90Hz. Only a 4300mA battery obviously can't hold its high power consumption. Under heavy use, it can't last for six hours, which is really a little hip pulling, In this regard, K9 adopts the design of 65W super flash charge, which can be fully charged in about half an hour, but also makes up for the corresponding shortcomings.

The day I saw the OPPO press conference, I knew that it would be more cost-effective to start with this mobile phone together with the TV, so I hurried to book and place an order. Although the number was a little small, once it was captured, it would be really fragrant. I said that it would be better to buy early and enjoy early while there is a first sale discount now. The first feeling after getting the phone is that the overall feel of the phone is good. The body is light and thin, only 172 grams in weight and 7.9 mm in thickness. Even if you hold the phone for a long time, you will not feel dropped. The transition of the four corner frame is smooth, without any cutting feeling. After watching his appearance, I tried several king games and chicken eating games. Because I basically play these two games every day, I took the lead to experience them. I felt that the whole game ran smoothly without pressure. It seems that the Snapdragon 768G processor is pretty good. At least it's OK to play various games with it. In addition, its endurance is also good. A 4300mA battery capacity and 65W flash can make my phone charge faster and last longer. When I saw this flash, I had to say that it was the first time I saw 65W used for a 1000 yuan machine. Although many other models under Oppo are using 65W, they are basically flagship and sub flagship. Like this 1000 yuan machine, the power is 30W. 65W is really rare in 1000 yuan machines. Oppo is truly the founder of fast charging, and it is arrogant enough. In addition, the use of the latest ColorOS11 system has also provided a better experience for this mobile phone. It has made in-depth customization for the game. It claims to have a five-dimensional game experience, and the actual experience also has a flagpole. The lightning opening for the game is not wrong, and you can skip the preloading process when opening the game, which is very pleasant to use, Basically, I was the one who led the advanced game when I opened the game with my friends.

The speaker of the mobile phone is not powerful enough. There is only a single speaker. The sound is not powerful enough when playing outside. It is not stimulating enough when playing games. For example, it supports 4D vibration, which can have a vibration effect after killing the enemy. If it is combined with the sound, it will be more powerful, won't it? And Shan Yang also has an impact. When watching some movies, even with Dolby Panorama Sound, the effect of dual speakers is still not achieved. It's a little pity, but it's not a big problem. It only needs a headset to solve it.

As an old OPPO fan, I know that the K series is synonymous with high cost performance, and it really gives me a good experience. The main selling point of the mobile phone is super performance. It's really sincere that the processor can be configured at this price. It uses the Snapdragon 768G processor. This is the first time I have seen the use of this processor. The first thing I get back is to open the game and play first. Emm, I found that after the upgrade of the system, the game space of the mobile phone has also been greatly changed. Opening various games from the game space can not only open the game by lightning, but also get game analysis. Take my favorite king glory as an example, it will show game situation, including the hero's restraint, or the hero's hint of being ban, which is very considerate, As a game enthusiast, this change may sometimes directly affect the decision of whether to buy this mobile phone. After entering the game, I saw the frame rate fluctuate slightly, and then it stabilized at more than 60 frames. I felt it was good. Moreover, the screen supports a 90Hz refresh rate, and you can feel the smooth transition of the screen when you play the game. The 180Hz touch sampling rate also makes the character's operation extremely easy. You can play the game happily. It is worthy of the name of the K series with super performance, and its heat dissipation is really powerful. After playing for a long time, the mobile phone has not been as hot as other brands. Another surprise is that it is also equipped with 65W super flash charge, which is the first time that OPPO has allocated 65W to the K series. I had always hoped that the whole people would popularize the super flash charge. Unexpectedly, OPPO took the lead in taking this step, which is worthy of being a big factory. It does have its own responsibilities, and it is also a good example for other brands, Hope that the follow-up can be followed up, and the flash charge will be gradually lowered as soon as possible, so that everyone can experience the changes brought by 65W.

The back cover of the phone is too easy to get fingerprints. Although the glass back is generally like this, it is too easy to get fingerprints, and it is not easy to clean up. I took a dust-free cloth and wiped it several times, but I felt that it could not be wiped off. I don't know why. The whole body is a bit dusty because of this fingerprint trace, It doesn't have the feeling of being tall when the machine was disassembled. This is a headache. I feel that this kind of bright glass should not be used in the future. It can also be replaced by AG sanding process or star diamond process.

I bought the K9 along with the TV. The scene was very popular. I made an appointment in advance and went in to grab it seconds after the sale. JD was also very powerful. It sent it to me the same day. It was a great feeling of instant satisfaction. I won't say much about TV. It's really good, and mobile phones and TVs can also do some interaction. It's also very valuable to start with mobile phones only 2999. The mobile phone I bought is the color matching of Fantasy Wings, and the other one is black. The black one looks more mature, and the color one is very suitable for our young people. It has a gradient color behind it, and there is a light pink under some angles. The girl is satisfied, and can show different colorful effects in different light environments, which is full of immortality, It can be seen that the designer has been working hard to improve his appearance. For example, this time, he has completely got our girls' preference. The appearance design of the mobile phone is also relatively simple and atmospheric, and the feel is great. The main reason is that it is thin and light and not tired. Compared with some half kilogram mobile phones, even after using it for a long time, it does not feel tired. At the same time, as a dual-mode 5G mobile phone, its network performance is very impressive. It supports the 5G intelligent scheduling function, allowing it to adjust the network signal according to the current signal environment and my use status, which not only provides me with good signals, but also appropriately extends the life of my mobile phone. Because for a 5G mobile phone, the endurance is very important. It has a 4300mA battery capacity, plus 65W charging power. Compared with some models, the battery itself is relatively high. It's OK to use it for 6-7 hours heavily. When the power is not enough, plug in the charger, and the phone can be fully revived in about half an hour, With this technology, I can really and unscrupulously play mobile phones. On the whole, it's a good value to spend 2999 to rush back. If someone wants to buy these 999 sets, they should have no more and can only buy them separately.

The chin of the mobile phone is a bit wide, which is understandable for a thousand yuan mobile phone, but it is not sure that it is better. For the K9, the other three sides are narrow, which sets off the wide chin. When the screen is lit, you can always see the black border at the bottom, which affects the appearance of the whole machine. Secondly, there are too few choices for the color matching of the appearance of the mobile phone. There are only two choices. The colors are a bit extreme, either black or color, which is a problem for some people who need color.

There are many reasons to buy OPPO K9. Although I like the appearance of this phone, the appearance of the phone is just a bonus, not a decisive factor for me. I chose this phone mainly because of its lightweight body and feel. The body of this OPPO K9 is only 7.9 mm thick. With a built-in battery capacity of 4300 mAh, it can achieve a body weight of 172g. Compared with my previous mobile phone, the battery capacity is a little larger, but the weight is much lighter. I can feel it is much lighter when holding it in my hand. In addition, the back of OPPO K9 adopts a 3D quadrilateral design. The corners are rounded without cutting hands. The body looks very slender, but the width is not increased. It still allows me to operate with one hand. In addition, the body is relatively thin, so I can hold it for two hours without worrying about the small thumb being pressed out. In addition, there is another detail I like about the phone. It also retains the traditional 3.5mm headphone interface. At least, I don't have to worry about carrying a adapter everywhere, and I don't have to choose between charging first or continuing to listen to music with headphones when the battery is low. I can use headphones while charging, which is nice, I don't understand what the current flagship aircrafts think. When it comes to charging, the biggest advantage of K9 is that its charging speed is super powerful. From plugging in the power supply, you can see that the power is growing at a visible speed. In half an hour, you can charge from 0 to 100. Indeed, the 65W super flash charge is different. It directly makes me feel the happiness of the flagship machine on a 1000 yuan fuselage, But then again, at present, there is no 1000 yuan machine that can match its charging speed. It is basically the king at the same price. In addition, the battery's endurance is also reasonable. It's basically OK to charge it every day. It saves the trouble of carrying the power bank every time you go out.

I'm still very satisfied with this phone at present, but I especially hope that this phone can have NFC function. First of all, many phones are equipped with NFC function now, and if the K9 does not have it, it will not affect the use of the phone. But if there is NFC, it will be very convenient to travel, and I feel that the existence of NFC function is quite meaningful, In particular, sometimes it is particularly troublesome to forget to bring a bus card, and you have to find the payment code of WeChat or Alipay manually. So I hope the mobile phone manufacturer will pay more attention to this small function.

OPPO K9 felt light and thin when it was just held in hand. It felt particularly good. The frame of the body was also round. No matter what posture you used to hold it in your hand, you didn't feel a hand scratch. The 172g weight of the body matched with the glass back. It felt good, so the mobile phone had a good experience when playing games. I usually like to play QQ Flying Car. This game has high requirements for mobile phones. Not only does the mobile phone run fast, but also the screen of the mobile phone has a high picture quality and refresh rate. K9 has all these conditions. It is a mobile phone with super performance, equipped with Snapdragon 768G processor, and has more than 450000 points in software, which belongs to the middle and high-end level, There has been a great improvement in CPU and GPU, as long as it is not a fever level game, it can cope with it. The powerful processor and the mobile phone also support a 90Hz refresh rate. The game experience is not bad. In the face of general mainstream games, it can be easily controlled. No matter how fast the car is or how hard it is to eat chicken, there is no need to worry about the problem of insufficient performance. Moreover, the mobile phone's image looks very smooth, and the virtual keys are also very easy to use, and there is no disconnection phenomenon. In addition to the satisfactory performance, there are many advantages of the mobile phone. For example, its 65W flash charging speed. I used to use more thousand yuan mobile phones, but I have never seen a thousand yuan mobile phone with a higher charging speed than OPPO K9. It is also the strongest flash charging in thousand yuan mobile phones, This is also the first time that OPPO has delegated the 65W super flash charge to the 1000 yuan phone. The phone itself also has a 4300mA battery capacity, which can provide enough power for daily use. The addition of this super flash charge is even more powerful. It only takes 35 minutes to fully charge the phone. It can be said that with it, it is no longer necessary to plug in the charger all night long, as long as there is no power, it is enough to recharge at random. For example, before going out in the morning, you can recharge it for a while, while on the way to work, you can play boldly. You can recharge it again before coming back from work, and you can play for several hours. This charging speed is really hard to return after using it

I think this mobile phone has a good gaming experience, so I really like to play games with it. But for a 5G mobile phone that supports a 90Hz refresh rate, the 4300mA battery capacity is a little small, which is difficult to support my heavy use. Usually, I have to charge after playing games for seven or eight hours. If the battery capacity can be larger, I can play longer, It will be more enjoyable for heavy game enthusiasts like me. I hope the battery capacity will be expanded to 4500 mA in the future.

I had planned to change a thin model for a long time. I was really tired of the trouble brought by this brick machine in my hand. After playing several games, I felt the hand ache directly. Now I find that my little thumb has deformed, and there is also a layer of calluses on the joints. Take the bamboo shoots!! It must be replaced. Since the light and thin machine is replaced, OPPO is still the first choice. You should know that most of the models they produce are light and thin. After my selection, I started OPPO K9, which is not only light and thin, but also has a high cost performance. The body of K9 weighs only 172g, and the thickness is 7.9mm. This lightweight model not only feels good in the hand, but also doesn't feel like a trouser pocket when carrying it in the pocket. However, I'm not used to it when I just change my mobile phone. Look at its appearance. After all, OPPO mobile phones are generally not ugly, and this one is no exception. Its appearance design is also ingenious. The body is still made of glass. Then there is a string of English letters inside the glass, and a large K9 beside it. I don't know what kind of technology is used, because this letter and number can be seen clearly only from certain angles, Anyway, the design is very interesting, and the visual effect is very good. I checked that string of English letters, which means super performance. It can be seen that the performance of the mobile phone is also a selling point of it. The K9 processor uses Snapdragon 768G. This processor has been upgraded on the previous Snapdragon 765G, which has enhanced its performance. Its software performance is quite good. I usually play games like Glory of the King occasionally, This kind of game doesn't have very high requirements for the processor. It feels good during normal use, and there is no problem in dealing with daily use. No matter how many background programs are opened, or how many programs are switched between, they are smooth without getting stuck. So I think the processor used by K9 is OK, at least for me, it is absolutely enough for normal use.

The appearance of the mobile phone is good, and the configuration is also good. However, people who like to play games should pay more attention to the battery life of the mobile phone. After all, no one wants to charge the mobile phone before it has played for a few hours. I usually play games for a long time. Basically, those who have played the king know that they want to continue to fight no matter whether they win in a row or even kneel, so it is easy to brake the car once they play. It is normal to play until they are banned. Therefore, the battery capacity of K9 seems to be a little small, which can not support my consumption. It is recommended to increase the battery capacity in the future.

As a cost-effective model under OPPO, the K series is also expected by many people. I have used K3 and K5 before, but now I have replaced it with K9. In fact, I originally intended to buy a K9 package, but the event was so popular that I didn't get it, so I bought this phone alone. Since it is cost-effective, the mobile phone must be developed in a balanced way. Let's talk about the hardware first. The K9 uses the Snapdragon 768G processor, which uses the 7nmEUV process. It is positioned as a mid end dual-mode 5G chip, which can support two kinds of networking. Compared with the previous generation of Snapdragon 765G processor, the performance is still excellent, It can reach 450000 points in the running score of Antu Rabbit, and its overall performance is in line with the positioning of K9. The Xiaolong 768G processor and the 8GB+128GB large memory combination have no problems in daily use. The mobile phone is very smooth. Even if I open many apps in the background, there will be no jam. The memory is also very large. Even if I download a dozen movies at a time, it does not occupy much space. Sometimes in places with poor signal strength such as the subway or high-speed railway, You can watch TV dramas that I downloaded in advance, so you won't be bored. In addition, K9 also performs well in taking photos. In terms of camera configuration, it uses 64 million ultra clear three camera combination. Compared with mobile phones at the same price, these lens configurations are definitely mainstream. I can see from the pictures I usually take casually that the overall picture is very clear, the details are presented well, and there is no obvious noise. At the same time, thanks to the support of video anti shake technology, K9 can also achieve the stability that most thousand yuan computers cannot achieve when shooting video, so the film rate is very high. And OPPO's latest ColorOS11 system, which is very aesthetic in terms of interface display, also supports many interesting functions inside the phone, such as the flash back button, the small window function, and the message pop-up screen. These small details seem unimpressive, but they can add a lot of points to my daily experience.

I think its configuration is rather careless. Whether it's the processor or the shooting of the phone, or the charging power and the body workmanship, it's the best one in the thousand yuan price range. The only thing I think is that the phone is equipped with only the bottom speaker, so I feel a little weak when holding the music outside, But fortunately, the original 3.5mm headphone hole has been retained in the phone, which at least allows me to plug in the headphone directly when I want to listen to music.

At present, with the price of 5G mobile phones gradually declining, I feel that the price of 5G mobile phones is not much more expensive than that of 4G mobile phones. Even though we don't have comprehensive coverage of 5G networks, I'm still going to buy a 5G mobile phone to use for a long time. This OPPO K9 is my ultimate choice. As my first 5G mobile phone, the K9 has brought me a good experience, especially in the network. The 4G mobile phone is also slow when downloading software with WiFi, but the speed of this mobile phone jumps very fast. A game with several gigabytes of memory is played in less than a minute, which is nice. The front adopts a 6.4 inch OELD hole digging screen design, with a screen ratio of 21:9. The width is unchanged from the previous 5.5 inches, but it is mainly improved in length. The narrower body width can achieve single hand grip, and at the same time, it brings a better grip feel. As for the screen, it supports a high refresh rate of 90Hz, and the screen is clear and delicate. The color display is also in place. The overall display effect is nice. OPPO K9 adopts two methods: face unlocking and screen light fingerprint unlocking. At present, it is also a mainstream unlocking method. I will not mention face unlocking, which is supported by many mobile phones, but this screen light fingerprint unlocking is quite different, which is not supported by many thousand yuan mobile phones, Most of them use the side fingerprint unlocking method or the post fingerprint unlocking method. Compared with the post fingerprint unlocking, the screen fingerprint unlocking avoids the opening of the body, and ensures the appearance and integrity of the body. Compared with the side fingerprint unlocking, the side fingerprint unlocking also does not show the phenomenon of false touch, because the side unlocking combines the unlocking area and the switch button, If you don't pay attention, the phone will turn on when you touch it when you put it back into your pocket, and sometimes it will cause the embarrassment of dialing the phone by mistake. So I think this design is very considerate, and the screen fingerprint unlocking method is also very accurate, and the unlocking speed is also fast. I hope to popularize it to other thousand yuan phones as soon as possible.

Of course, OPPO K9 also has its shortcomings. Its appearance is indeed online, but when the screen is lit, its shortcomings are revealed, that is, its jaw is a bit wide. In this era of face viewing, appearance occupies an important position. The other three frames of K9 are relatively narrow, and the screen proportion is also high, which makes the chin a bit wide. However, it does not affect the use, but the aesthetic feeling will be a little inferior. Of course, this is also a common problem of most thousand yuan machines. For those who do not pay much attention to the appearance, this should not be a big problem.

Speaking of its advantages, let me first talk about its flash charge. It's the first time to see a 65W model in this price range. It can revive the phone in about 30 minutes. Isn't that a major advantage. Although there is 120W charging power in the market now, there is not much improvement in the charging time, and they are all equipped for the flagship machine. So you know, the price is too high. It is good to use 65W in the 1000 yuan machine, which means OPPO can be so arrogant. It is good to give 33W for other machines. Although the charging time only takes about half an hour, it does not mean that the phone's battery capacity is small. On the contrary, it is equipped with a 4300 mA standard capacity battery, which is enough to provide me with a day's consumption. In addition to its strong endurance, its other advantage is that in taking photos, the front camera is 32 million yuan, and the rear camera is a 64 million main camera+8 million ultra wide angle+2 million macro three camera combination. Just looking at the camera parameters, you can see that the photography performance will not be poor, not to mention that this handheld has a variety of shooting methods. I usually take self portraits more often, so I can clearly find the difference between this phone and other models. In the past, the beauty of the phone was still in the stage of full face skin grinding, but the beauty of this phone is relatively more natural, and the image taken is also very good, more humanistic, When multiple people are shooting together, they will be optimized according to their respective facial features. It is no longer a special effect for all people. As for the rear, it supports night view, wide-angle and other styles, as well as AI enhancement mode to enhance the effect of live shooting, so the effect of photos taken by it is also good, but it is obvious that only taking videos with it can give full play to its skills. Because of its super dual anti shake support, it can calmly cope with the shake problem that may occur during shooting, Output some more stable pictures, which will be more friendly for some children who like to record their life with video.

In fact, there is no problem with the configuration of this mobile phone. After all, the price is set there, and it is a 1000 yuan mobile phone. You can't force it to have the configuration of a flagship phone. The advantages and disadvantages should also be based on the actual situation. I think it's a bit inappropriate that the current mobile phones are all made of glass, because summer is coming soon. Don't people like me who sweat easily have to face the fuselage every day? Wipe your fingerprints every day? It's not as good as the anti fingerprint fuselage design of Reno series.

OPPO's 5G mobile phone is very good. At present, most 5G mobile phones in the market weigh about 200g, while the K9's body is only 172g. It is not only light and thin, but also has a declining appearance. All configurations are OK. In particular, I would like to talk about its image shooting and instant recording software. These two special features are very practical for those who like to take photos and videos. When taking videos, the anti shake function of the mobile phone can perfectly solve the problem of video jitter that I encounter most of the time when taking videos, Even if the hand is mild Parkinson's, the video shooting can be stable. The appearance of the phone is very good. There are two colors to choose from, Spades K and Fantasy Wings. Each color matching has a different style. The one who likes low-key is suitable for Spades K. I chose Fantasy Wings. Its color is dazzling, which makes it difficult to ignore. This is exactly what I want. In addition, the battery life should also be considered when buying a mobile phone. I don't need to worry about the battery life of this K9, because it is equipped with a 4300mAh large capacity battery, which greatly improves the battery life of the mobile phone. And it is equipped with 65W super flash charging technology. This charging speed is hard for me to return once I use it. After all, this mobile phone is less than 2000 yuan. I was surprised to be able to carry 65W super flash charging technology. Let's see who else in the market is so willing to feed the 1000 yuan mobile phone. Finally, let's focus on the shooting experience. The camera pixel value does not need to be introduced too much. The real shooting effect of the mobile phone is the best proof. However, in the process of my use, the best use is the anti shake function and the recording app. The former perfectly solves the possible jitter problem, while the latter can make my videos more beautiful, such as adding a suitable background music to the video, adding a subtitle for everyone to watch, or cutting multiple videos into one, It makes video creation easier. The most important thing is that it is easy to operate and easy to master, which can be mastered by novices.

Every price is worth every product. Although K9 is relatively cost-effective, considering that it spends part of its economic budget on appearance and configuration, the processor is slightly inferior, and its performance is certainly not as good as that of the Snapdragon 865. However, this processor can also be understood when used in it. After all, the price is there. Don't always look at it with some models, After all, the positioning of the mobile phone is different, and other configurations are also placed there. There is no doubt about the strength of the mobile phone. What's more, the mobile phone has 65W flash, which is very conscientious.

For me, there is really no special requirement for buying a mobile phone. As long as it is cheap and can meet my daily use, it's OK! In fact, I usually just play music, chase dramas, shoot videos, and occasionally play games. So basically, I choose phones that are cost-effective. For example, this Oppo K9, which focuses on cost performance, meets my needs. It focuses on comprehensive development. It uses a Snapdragon 768G processor. A G behind the number means that the game has been customized. It is suitable for playing games. I played several popular games, which were smooth and did not get stuck in the running process. In addition, the 90Hz refresh rate can fully meet my daily game needs. At the same time, it is also equipped with a 6.4 inch OLED screen. The color display of the screen is very rich and the details are very clear. This screen has also passed the eye protection certification, which can effectively filter a large number of blue light. This is worth praising. It is estimated that many people are like me. They play with their mobile phones all day long. If the mobile phones do not protect their eyes, they will feel sour and uncomfortable after using them for a long time. Especially when they stay up late at night to chase novels, they feel uncomfortable with their eyes. Therefore, passing the eye protection certification means that they will take better care of their eyes. In addition, this mobile phone also has a 64 million rear three camera combination. In addition to the main camera, there is also an 8 million wide-angle lens and a 2 million macro lens, which support multiple shooting modes. Among them, I prefer to use the background virtualization function, which can make the painting feel more layered and highlight the main characters. I always use the C position wherever I go. The front is a 32 million pixel lens, with its own AI beauty effect, which can be adjusted to suit my beauty effect according to my facial information. Whether it is a self portrait or a group photo, it can be matched with a suitable beauty scheme according to each person's face shape. It is very convenient for mobile phones to have such AI beauty technology.

The overall hands-on experience of the oppo K9 is very good. Both the appearance design and the configuration of the body are OK, but I think there is one thing that can be improved. For example, its battery capacity is 4300 mA. This size in the same price model is standard, and I always play with it, As a result, my mobile phone can't keep up with my consumption speed. Therefore, I think the weight of the fuselage can be adjusted from 172 grams to 180+grams, so that the battery capacity can also be increased, which can effectively extend my service life.

What I started with was the color matching of Fantasy Wings. It is obvious that this color matching is more valuable between the two different colors. The Colourful Wings also have the right name. It really has a kind of Colourful effect, especially when the fuselage is rotated to different angles, it can unlock completely different colors. In addition to its excellent appearance, its photo taking performance is also very good. It is worthy of OPPO's mobile phone, and it has done a good job in camera optimization. For example, portraits and night scenes are very comprehensive. For example, before taking photos, I can adjust the effect of the mobile phone's background virtualization, and then choose my favorite intensity of virtualization according to the actual situation. After taking photos, The sample sheet is also close to the real effect, and the portrait is well separated from the background, with clear and natural edges. My biggest hobby is taking pictures. In fact, when taking pictures, there is a great demand for electricity, because not only do I have to take pictures, but also keep the screen lit. The body of the k9 weighs only 172 grams. In the slim body, a large 4300 mAh battery is inserted, which provides enough power for me to use for a day. According to my usage habits, it takes me about an hour more to commute every day. I can watch videos, listen to music, brush microblogs, and play without fear of power consumption, because the flash charging technology of this mobile phone is good, It supports 65W super flash charge, which can be charged to 36% after the phone is powered off and connected to the power supply for 10 minutes. This speed can be said to be amazing, which has eased my battery anxiety problem. It is a true portrayal of five minutes of charging and four hours of drama chasing. When I was out with my friends on the weekend, I had to take photos. When the power of my mobile phone was low, I just found the socket and charged it for half an hour to quickly return my blood. I could continue to play for several hours. The charging experience of K9 was so great.

This mobile phone has its own night view mode, which can suppress the excessive highlight and lighten the dark part at night when the light environment is more complex, so that the picture can reach a good balance. But I think it would be better if we could optimize the night scene, because it can shoot well when there is a light source, but when there is no light source, the phone image still looks a little dim. As for other hardware shortcomings, I don't think there is anything to be picky about for the time being.

I have been using this mobile phone for almost two months, and the most satisfying thing is the performance of this mobile phone. K9 uses Snapdragon 768G processor. I also used Anthare to score 688 points for a single core, 1988 points for a multi-core, and 45W+for performance. It's a mid tier processor. Everyday I play games with this mobile phone. When I open a high frame rate and high image quality, one shot of the shot gun can run smoothly. Moreover, the screen refresh rate of this mobile phone is 90Hz, which can provide a better operation experience for internal games, such as playing chicken games, which require frequent rotation of the perspective. Previously, I used a mobile phone with a 60Hz screen refresh rate to operate with a slight sense of stuttering. The use experience is not very good, but now I use K9, even in the case of complicated scenes such as driving a steel gun, Turning the screen is as smooth as opening the mirror. In addition to the screen K9, 3D liquid cooling heat dissipation is also provided this time, using a large area of VC liquid cooling copper plate and multi-layer conductive graphite sheet. In fact, the thing I fear most when I use my mobile phone in summer is heat, because it's OK to warm my hands in winter, but it's easy to make my palms sweat when my mobile phone is hot in summer, and the sweat on the screen will affect the operating experience of using my mobile phone. I have never used K9 in this way. Even when playing games, the overall temperature of the phone is warm. There is no overheating or scalding. The system of this mobile phone is also very easy to use. The K9 is equipped with ColorOS11 system, which has many more functions than the previous generation mobile phone system, and is very practical. My most commonly used function is the flash window, because it can play games and chat without error, saving the trouble of switching applications back and forth. Another is the screen sharing function. Previously, this function could only be used on computers, but now it is more convenient to use mobile phones. For example, when I communicate with my colleagues about some work problems, it is convenient to see their operations more intuitively by sharing the screen. Because I am doing design work, the final draft needs to be confirmed repeatedly. With screen sharing, I can see the picture more intuitively, and avoid the trouble of unclear dictation.

The game performance of K9 is very good. It has a 90Hz refresh rate screen to ensure the feel and smoothness of the game operation, and 3D liquid cooling to ensure that the phone will not get hot. It would be great if the linear motor was added to the motor, but K9 is a rotor motor, which is a pity. For example, when I play Peace Elite, when I open the 4D shock shooting and get attacked by the enemy, there will be a shock. This way, the game experience will be better. However, the shock experience of the rotor motor is worse than that of the linear motor. I hope that the next generation of products can provide the linear motor.

Now people buy mobile phones all talk about their performance and how high the processor scores are. To be honest, when I first got the K9 mobile phone, I really cared about this. After all, it is a mobile phone with the main cost performance ratio. It is smooth to use and does not get stuck. It is the main thing to meet my mobile phone performance needs. However, it took more than a month to discover that this mobile phone not only has good performance, but also has not collapsed in terms of photographing and endurance. The main camera of this mobile phone is 64 million pixels. Usually, I take this mobile phone to record my daily life or punch in the tourist attractions, and the photos are very clear. With the 8 megapixel wide-angle lens of this mobile phone, when I am facing a large scene and I am close to the scene, I don't need to worry about having a wide-angle. I can also record the scene I want to take. This mobile phone also has a 2 million pixel macro lens. When I first used this mobile phone, I thought that the macro lens was just a decoration and had no practical value. But when I went to the park to see many beautiful flowers, I took this mobile phone to take photos. I found that the details of flowers can be clearly displayed, and I found a new land for taking photos instantly, So that later I would take this mobile phone to take photos when I saw flowers and plants on the roadside. Then there is the battery life of this mobile phone. The K9 is equipped with a large 4300 mA battery. Usually, I can use this mobile phone to charge once and still have about 30% of the battery life in one night. Even if I play games, I can play games for four or five hours in a row and consume about 50% of the power. I'm still satisfied with the battery life. The important thing is that K9, as a 1000 yuan mobile phone, uses 65W flash charge. Usually, this mobile phone has no power, and more than 30 minutes of charging time can bring this mobile phone back to life, which is very convenient. Because before, my mobile phone didn't have a quick charge, and it took more than an hour to charge each time. I often worried about the battery life of my mobile phone for fear that it would run out of power. Now I use the K9, even if the phone has no power, I don't panic. Ten minutes of charging can restore about 30% of the power of this phone. I never worry about the battery life of the phone again.

This K9 photo taking, charging and performance are all in line with my mobile phone needs. The disadvantage is that there is no wireless charging. Although 65W flash charge can guarantee the battery life, it is not a big problem, but it is more troublesome to unplug the charging cable than to directly place the phone on the wireless charging stand. For example, when playing games, wired charging will hinder the operation, and wireless charging will not have such trouble. In addition, charging with or without cable can be used when charging, Don't worry that the phone will be nice when it runs out of power.

In fact, I don't have enough budget for mobile phones, but I have a lot of requirements, which belongs to consumers who have more things than money. First of all, its face value must not be low. Second, its daily photography is good. Finally, its performance cannot be too poor. I started this OPPO K9 based on this principle. After using it for more than half a month, let's briefly share the advantages and disadvantages of the mobile phone. Compared with the mobile phone I used before, it can be said that it is a super value mobile phone focusing on cost performance. In my opinion, the thinness of the phone body is very important, because the phone is too thick and heavy not only affects the feel of use, but also affects the level of playing games. For example, many 5G mobile phones now weigh more than 200g, because it is not easy to balance the power consumption of mobile phones to achieve both thin and light weight and high endurance. OPPO K9 solves these problems well. When the thickness of the phone body is only 7.9mm and the weight of the phone body is only 172g, a 4300mA battery is added to the phone, which is a clean flow in 5G phones. In addition, K9 also carries a 65W super flash charge, which can recover more than 20% of the blood in 5 minutes, more than 60% in 15 minutes, and from 0 to 100% in 30 minutes. It perfectly solves the problem of endurance. You know that this super flash charge is usually invisible on a thousand yuan machine. I spent more than one thousand yuan to enjoy the flagship treatment. Why not. In addition, it also has an OLED eye protection screen with a 90Hz refresh rate, which has a good visual perception. The Snapdragon 768G processor can cope with some of the current mainstream games very well. The chicken eater can run smoothly. In addition, its thin and light body will not hurt your hands even if you play with your mobile phone for a long time. It is full of immersion. As for the photo performance of mobile phones, K9, as a member of OPPO mobile phones, has undoubted strength. Although I don't take many photos, it can handle all the shooting scenes I need.

In fact, this mobile phone processor can be matched with a better one. Now it uses Snapdragon 768G, but because it is cost-effective, this processor should be slightly inadequate. At least a Tianji 1100 processor will be more suitable. However, there is nothing wrong with the current mobile phone processor. At least it has a good balance effect in power consumption control, which brings me a really good experience.

For OPPO K9, what I am most satisfied with is the price performance ratio of the mobile phone. The price and configuration are very good. Because I usually drive more black cars, I have certain requirements for the network speed and performance of the mobile phone. The old mobile phone was replaced because it has been used for a long time and the mobile card affects the game experience. This OPPO K9 uses Snapdragon 768G chip, supports dual mode 5G network, covers domestic mainstream 5G dual mode frequency band, and can choose the better one according to the current signal strength, which ensures my stable signal, and the daily black signal is stable without interruption. Also, I have to say that this mobile phone has a 90Hz refresh rate, and supports a maximum 180Hz touch sampling rate. It is more comfortable visually, and the operation on the hand is more sensitive. Every slide is smooth, and the game experience is improved. After all, the win or loss of the game is always in a flash. When I play the game with this mobile phone, whether it is a steel gun or a driving vehicle, the picture is very smooth and there is no sense of stuttering. In combination with the sound quality of my AirPods, you can hear the sound of gunfire in the distance or footsteps in the vicinity clearly. The network speed not only ensures the game experience, but also eliminates the loneliness on the way of business trip. It is not a problem to brush a beep in a place with poor signal such as the high-speed railway. There will be no problem of no signal in the car. Next, let's talk about the battery life of the mobile phone. After playing the game for a few hours, I thought it needed to be charged, but when I returned to the desktop, there was still 40% of the battery left. This shows that the battery is quite durable, and its charging speed is also very fast. After the 65W flash is plugged in, I can see that the power is rising rapidly, from 0 to 100 in half an hour, with its own 4300mAh battery capacity, The overall endurance performance was quite good. I didn't charge all night after using this mobile phone. I used the washing time to charge when I got up in the morning. It was almost charged when I went out. I had no problem with commuting.

The K9 is very satisfactory both in appearance and configuration, but one thing I am not satisfied with is that the lens on its back is convex, and the bare machine is not flat when placed on the table. It is easy to grind the camera when the screen is placed downward. Of course, this is a disadvantage of most mobile phones without protective covers. I think the camera can be placed inside the glass back panel, just like reno2, which can not only better protect the phone camera, but also have a better feel for the integrated back.

The first feeling of unpacking K9 is that the workmanship of this phone is excellent. Although you can see the real machine picture on the Internet, it is not as real as the actual feeling. The four corners of K9 are designed with curved surface, and there is no obvious touch when holding it. Especially when I hold this mobile phone horizontally to play games, it is very exciting to use. The weight of K9 is only 172g, and you won't feel tired after playing games with this mobile phone for a long time. With the 7.9mm thickness of this mobile phone, you feel light and thin in your hand, which is much easier to use than some half kilogram mobile phones. Then there is the game experience of this mobile phone, because the most important thing for me to start this mobile phone is to see its game performance. The screen is provided with an OLED screen with a refresh rate of 90Hz, which enables me to have a better operating experience in the game match. For example, in the game of releasing skills such as the Acer, a higher screen refresh rate will enable me to release skills, make the picture of playing ball games smooth, and have a more comfortable visual experience. In fact, this mobile phone is equipped with a 3D liquid cooling system. Now it is summer. Sometimes, when playing games in an environment without air conditioning, the mobile phone heats up, which easily leads to sweating in the palm. Then the sweat on the mobile phone will lead to poor operation and annoyance, and the screen of the mobile phone will often be wiped. This is not the case when I use the K9. Even when playing a game that consumes more power than the king, such as eating chicken, it is great that the body temperature of this mobile phone will not get hot. In real summer, no one wants to hold a hot mobile phone to play games. For playing games, the battery life guarantee is also very important. The official gives five minutes for charging and two hours for blackout. When I actually used it, I found that the charging of K9 was really powerful. The 65W flash can fully charge this mobile phone in more than 30 minutes. There is no need to worry that the mobile phone will lose power when it is turned on black. I am quite satisfied with the workmanship, screen, system cooling and charging of K9. As a key cost-effective mobile phone, K9 is not only full of materials, but also has a very good use experience. It is a highly cost-effective mobile phone.

There are no dual speakers. I hold video conferences like usual work, including my daily entertainment, music and drama. If there are dual speakers, the hearing experience will be better. Because my previous mobile phone does not have dual speakers, the voice of WeChat video conference is relatively low even when the hands-free phone is on in a noisy environment, which is easy to lead to hearing what is being said on the opposite side. Fortunately, the volume of K9 is still quite loud. I tried video calling, and it will be shocking when I open the hands-free phone, which avoids the embarrassment of not being able to hear what the other person is saying.
