Possible chip damage? Phone reboots every 2-4 minutes.

Hello,

A customer has brought me an iPhone 5C for power issues. Upon opening the iPhone I can see that the screen has been previously replaced. Phone appears to be clear of water damage.

The phone reboots every 2-4 minutes, either plugged in or not plugged into a charger. Replacing the battery makes no difference and restoring the phone through a DFU does not fix the issue.

I have managed to locate some board schematics but have not a clue which area and chips to look at.

Hope you can help.

Thank you kindly.

Thank you for your reply. I have tried a few batteries with the same result.

What am I looking for in terms of these filters?

Board examination is completely new to me.

Thank you!
