Need to remind everyone that the iPhone 4 and 4S batteries are not compatible with the iPhone 5 in terms of size and capacity, and there is currently no third-party battery for the iPhone 5 on the market. Thanks to the CIPAS staff for the disassembly, the replacement of the battery is expected to take 20 minutes (of course, this is the time spent by professionals, novices depending on individual ability).
**Steps, open the iPhone.
- Because the iPhone 5 is equipped with the same screws as the small 4 and 4S, we can still use the 4S screwdriver to remove the iPhone 5.
- Use the suction cup to suck up the screen of the iPhone 5, but it is not completely peeled off, because at the top of the fuselage, the screen components still have wires connected to the motherboard, and can not be pulled arbitrarily.
- In this way, draw one side and keep the other side.
