Have you ever met your iPhone 5s battery leakage and PCB overheating? This is the common issues among the iPhone 5S users. However, using faulty phones is always unpleasant. So, we need to fix it. First, plug the adjustable DC  power supply  and the standby current is about 50mA. After 1 min, we can feel that the baseband circuits and the front and rear sides are hot. Unplug and plug the adjustable power supply for several times, we can feel that USB Control IC  U2 gets hot faster than other parts. Then, according to the repair experience, we remove USB management chip U2. The motherboard  without U2 is shown in picture 1-1. 1-1 USB management chip U2 in bitmap is shown in picture 1-2. 1-2 Finally, Replace U2 with a new USB management chip and assemble the iPhone. After testing, the electricity leakage disappears. The issues is gone, and the iPhone 5s can back to normal work.

There a joke said that you don't have to fear the cold winter if your phone temperature is high enough. But when it happens on your phone, you will be troubled by this.

First, use an adjustable power supply to charge it and charger shows 4.28 A current flow (picture 1-1), which is an obvious shout circuit. Use multimter  to measure the diode data to ground of battery interface, which is normal. We continue to measure and find that the main power supply PP_VCC_MAIN is short circuit to ground. 1-1 Second, observing under microscope , we find no abnormality on the surface of capacitors on the circuits connected with PP_VCC_MAIN. We use burn-in method to check the faulty points, using an electric soldering iron  to light rosin on the circuits. We find a capacitor under CPU is extremely hot and it burn out the rosin. The capacitor’s col...

Most owner of iPad Air has been through this case, iPad Air cannot be charged when turned on while can be charged when turned off. You must think what the situation is, and how can fix it.
