How to identify the authenticity of Apple's mobile phone battery

Apple mobile phone battery authentication method is as follows:

1, first from the appearance analysis. The original iphone battery has words on both sides, and the font color is not pure white, but light blue on a white background. One side has the serial number and two-dimensional code of the battery, all of which are sprayed by code spraying technology, with clear handwriting and obvious spraying point. The factory serial number and QR code of non-original batteries are similar to seals, which can be easily erased with fingers or rubber.

2. In addition, a sponge pad is attached to the back of the cable interface of the original battery to prevent poor contact between the interface and the motherboard. Some non-original batteries are also original sponge pads, such as high imitation batteries. After disassembling this battery, we can see obvious manual welding marks on the PCB board and battery cable. But if there is no sponge pad, it is definitely not original.

3. Comparing and observing from the front of the battery, it will be easy to distinguish the difference between original and non-original. The Apple logo on the original battery will be higher, and there are 60950 battery certification standards below. This standard includes certification countries, certification items and testing standards. Non-original batteries are not certified, so there is no certification standard. In addition, the original battery is made of colloidal electrolyte, so it is normal for the battery to feel soft when you pinch or break the battery slightly. On the contrary, when you squeeze or break the battery with a small force, the battery will feel hard without any deformation, which is abnormal.

4. Let's further distinguish from battery disassembly. The one on the left is the original battery, and its PCB is made by UMT (Taiwan Province Xinxing Electronics), with clear marks and complete and neat fonts, while the PCB board of the non-original battery on the right is believed that you can see the problem after comparing the marks. Moreover, from the manual mark on the chip, it can be seen that it is assembled rather than original. In addition, some non-original batteries can even see that the components on the PCB after disassembly are different from the original ones, and there are obvious welding marks. The cable of non-original battery will feel softer to hold, while the cable of original battery is relatively hard and not easy to deform.

5. And the production date of the battery. For example, the batteries of iPhone5S are basically produced around 20 13 and 14, while the batteries of 20 16 are basically imitation batteries or assembled batteries. Similarly, other models can also choose this identification method for simple preliminary judgment. The difference between the battery life and the machine market is 1 year, which can be estimated with reference to the interpretation of 5S. If the difference is too long, it is a non-original battery. The red mark on the right side of the picture below is a 5S non-original battery.
