Previously, the charging head network has supported many modelsWireless chargingFor charging measurement, whether it is iPhone type magnetic suction typeWireless chargingHuawei, Xiaomi, OPPO and vivomobile phoneHorizontal and vertical placement of classWireless charging, match with your ownWireless chargingThe charging experience after the product is more friendly;But if you need to have a magnetic suction experience, you need to wearmobile phoneAccessories, but does its charging power affect?Next, theSamsungS23 Ultramobile phoneConduct actual measurement verification.
Product Introduction
The products tested this time are of conventional magnetic suction functionmobile phoneShell, which can be purchased on various e-commerce platforms, is the most basic magnetic suction with frosted fog surfacemobile phoneHousing, adaptableSamsungS23 Ultramobile phone.
First, in terms of wearing experience,SamsungS23 UltraThe fit between the phone and the phone case is impeccable, and the camera module is free of any obstruction.
There is no obvious shaking of the side keys.
The opening design of the bottom middle frame is still 1:1 to restore the real machine.
SamsungS23 UltraThe overall thickness of the mobile phone case is about 11.36mm.
This phone case weighs about 43.1g, which is heavier than the regular silicone case.
At this time, the weight of the phone with the case is about 278.7g.
Magnetic suction experience
From the official data,SamsungGalaxyS23 UltraThe phone supports 45W wired charging and10WWireless charging, in the previous charging test, the performance was in line with the official claim;This time, different wireless chargers will be used to simulate users' daily use scenarios.
In terms of magnetic attraction performance, the magnetic attraction of the mobile phone case with magnetic attraction function purchased by the user is still strong enough to support the shaking situation under normal use.
In terms of the sense of grip, users will not have an obvious sense of foreign objects whether they are brushing videos with one hand or playing games with both hands. However, it is necessary to note whether the length of the wire meets the needs of users when they are sitting or lying.
After the mobile phone is worn with the mobile phone case, the measured output power of the power supply charger terminal reaches 9.67W.
When the second wireless charger was measured, the output power of the power supply charger terminal reached 6.7W.
When the third wireless charger was measured, the output power of the power supply charger terminal reached 6.62W.
On the whole, the above three wireless chargers all support Qi certification. Theoretically, the charging power of mobile phones (bare metal status) is not different, but its charging power is greatly affected by temperature. At the same time, in the electromagnetic reaction of wireless charging, the distance increases after wearing the mobile phone case, the conversion efficiency decreases, and the heat will increase, so there will be varying degrees of change.
Full charge test
Samsung S23 Ultra mobile phone and Apple MagSafe magnetic charger were placed in a 25 ℃ incubator, connected to the power supply, and POWER-Z KM003C was used to record the data. The test data are as follows.
Connect the Samsung S23 Ultra to the Apple MagSafe magnetic charger, connect the power and shake hands with the 9V voltage gear, the power is stable at about 6.4W, lasting for 4 hours and 43 minutes;Then the charging power drops in a "straight line" until the phone is fully charged. The whole charging process takes about 4 hours and 56 minutes.
Draw a line chart. It can be seen that the Samsung S23 Ultra phone is charged to 50% in about 2 hours and 26 minutes, 80% in 3 hours and 54 minutes, and 100% in 4 hours and 56 minutes with Apple MagSafe magnetic charger.Charging speed is average.
Temperature performance
Next, let's take a look at the charging and cooling effect of Samsung S23 Ultra with magnetic phone case.
Charge Samsung S23 Ultra with Apple MagSafe magnetic charger, put it in a 25 ℃ incubator for 20 minutes, and then use a thermal imager to shoot the maximum temperature on the back of the phone is about 36.7 ℃.
Summary of charging head network
For mobile phones that support wireless charging function, taking Samsung S23 Ultra mobile phone as an example, it can be seen that users can purchase adaptable magnetic phone cases under various e-commerce platforms. The thickness of the phone case has no obvious difference in adaptability compared with the conventional silicone phone case, but it is generally heavier and thicker;In the process of wireless charging, such design may lead to poor cooling capacity and low conversion efficiency.
At the same time, the charging head network has previously introduced Huawei Mate 60 series micropump liquid cooling case, whose temperature performance and wireless charging performance are more friendly.Finally, for mobile phones that support wireless charging (not iPhone 12 and above), users can purchase a magnetic phone case and use it with a magnetic charger/power bank, which can not only charge but also experience the function of the viewing bracket, free their hands and avoid slipping.
