iPhone 5s Turns Off by itself
So I have had this iPhone 5s since it first launched, and the batt died last August. Got a battery replacement mid December.
1. The phone would mysteriously die when not in use. In 24 hours it'll for sure turn off by itself. Over night it'll shutoff. Keeping iPhone plugged in doesn't solve the problem, it'll still shutdown.
2. When around 20% batt left phone would shutoff, when plugged in will turn on again normally.
3. Changing to another batt didn't solve the problem. I bought like 5 replacement batteries, none of them fixed the problem, tried them on my other 5s as I have about 4 of them, worked perfectly fine, no random shutdowns.
Which ic chip is most probably busted? Main power IC or the U2 chip? Or is it something else??
In diagnostic there is Panic code
which one? the one @ the very right?
Is this a good question?
