iPhone 5s slowly charging and fast battery drain

Hi,

i got an iphone 5s which is charging very slow and fast battery drain.

It doesn't matter if the phone is in flight mode or not.

I think, it is an IC problem.

Does anybody knows, which IC is causing this problem?

Power Management Control IC PM8018 or

Power Management IC 338S1216 or

U2 IC 1610?

More than likely the U2 IC that is damaged, as this chip is damaged easily with copy chargers etc.

This causes things like fast battery drain (even in airplane mode)

Overheating

And a few other symptoms.

Replace that and see what results you get. :-)

Replace the battery is the first step to do.

Then, if still not working, should be IC or water damage.
