Coolpad COOL 20 (4GB/64GB/All Netcom)

1. Appearance: At the lowest price of 699, the glass backplane is given. It can be said that the materials and appearance are very competitive, and the backplane shape and camera module are very excellent. They don't have the perfunctory feeling of ordinary hundred yuan computers. It is difficult for those who have a special preference for sandwich rectangular frames to resist. 2. Photographing: 48 million pixels of main photography, plus the support of the iris algorithm, is very competitive at this price, the actual shooting effect is also excellent, and the analysis, color restoration and film rate are excellent. 3. Optimization: It claims to use the EROFS technology of the same model of Huawei, and is satisfied with the daily opening speed of the APP. Compared with Huawei P30, the average gap is about 1s, which is excellent at this price. 4. Performance: basically enough. Having tested such two-dimensional lightweight games as FGO and Tomorrow's Ark, I am fully competent. Anyway, heavy game players won't buy it as the main machine. 5. Endurance: 4500mAh battery, but not lost. 6. After sales: We promised to guarantee a two-year warranty and a 90 day replacement. The after-sales standard is relatively high. Of course, there is no chance to measure this... In addition, the official promotion is still very strong. No matter Tmall or JD, they give away a lot of small things when buying a machine 7. Conclusion: The high appearance at the same price, good optimization and sufficient configuration. Those who like the straight sandwich style and have a certain sense of identity with the brand of Coolpad can consider buying it as a standby machine or an elderly machine.

1. Appearance: The frame is made of plastic, which is understandable, but the effect of this plastic treatment is more casual. The surface of the frame is only smoothed, and there is no metal layer. In addition, the plastic mold of the frame does not feel accurate enough, especially the keys, card slots, earphones and other positions have some "meat". It can be said that this cheap plastic frame is the largest slot in the appearance of this mobile phone. 2. Screen: Only 720P resolution screen is used. Although LCD screen technology has been very mature in recent years, and the quality of this screen is still good, 720P screen is not considered as an advantage. And the front chin is too wide, which is also a button item. 3. UI: It uses its own CoolOS, and the current version number is only 1.1. The interface is highly respectful of MIUI, which is understandable for such a fledgling UI. The function is still lacking, and there are some small problems, but the overall problem is not big. As a standby machine, it can be competent. 4. Advertising: The search box at the bottom of the screen cannot be closed. Clicking or drawing on the main interface will bring up the built-in browser, which will scroll to display some "hot news", which is annoying. Coolpad may need to make a profit when it returns to the market. How to say, understand but not accept this hard advertising method. I hope the updated version can be set to close in the future 5. Charging: It seems that the charging power is only 10W, and the charging is very slow. Fortunately, the battery life is not bad. 6. Version: The price performance ratio of 4+128 and 6+128 is not very high, but when the system itself accounts for about 18G, the availability of 64G is very low. Even as a standby machine, it will also affect the playability. It is recommended to buy two versions of 128G. 7. Size: The length and thickness exceed that of the iPhone 13 Pro Max, and the weight of the bare machine also reaches about 199 grams. The holding feeling of the sandwich shape with right angles is not very good. The thickness and weight need to be adapted. As a standby machine, it also takes up more space. If Coolpad is willing to lay out the middle and low-end market, I would suggest some small screen, more sophisticated mobile phones.

cheapness

At first, it was OK, but after two years, something went wrong: 1. Frequently flash back, often open small programs randomly 2. The network signal is poor, and the Internet is often disconnected 3. After factory settings are restored, data traffic cannot be used, only WiFi can be used
