iPhone 5s no power, CPU hot

Messagepar breckjensen » 30 Nov 2017, 09:39

Hi, I have an iphone 5s and when I press the power button the cpu heats up and draws 700mA of power supply. While not press the power button the phone draws 1mA.

Phone history: The phone was damage by water and then I found short the PP_1V8SDRAM line. I checked capacitors and found the short on the power ic. Once the power ic was replaced, the short was fixed.

I have checked 1v8sdram and 1v2sdram lines, and i get 3.32V and 2.2V respectively. This is very strange and I have no idea why this happens.

Please help.

Thanks!

I didn't find the right solution from the Internet.
