Why is my phone's A6 chip getting hot?
My iPhone 5's A6 chip is getting hot even when i just turn it on and when i'm not using it. The battery drains super fast, but the battery works fine (I plugged it into a different iPhone 5 and it was fine). It charges really slow too and only charges with a specific adapter from 30 pin Apple plug to lightning and it says the other cables aren't certified by Apple, even an official Apple cable and won't charge at all if it dies. If it does i have to charge it till it turns on with a different phone then put it back. Should I just get a new circuit board? I've replaced the charging port already and the battery is from iFixit.
I also upgraded to iOS 10 and it didn't change anything and i've calibrated the battery.
So to sum up: hot A6 chip, very fast power draining, slow charging, only charges with one cable adapter.
Thank you to anyone who replies!
Is this a good question?
