iPhone 6 overheating battery and won't charge at all
I've changed whole back case, battery and lcd.. Phone worked normally for like 3 days and suddenly it wouldn't charge anymore. It would stuck on 1% on charger and if disconnected from charger, it would turn off. Anyways, it still could turn on and charge to max 1%. I've carried my phone to three top services in my city and after the first one I couldn't even turn on my phone anymore - like its dead. He said that battery is over drained and the second one said he doesn't know what the problem is, because both of them have checked U2 Chip, replaced battery, checked voltages, everything acts like normal, but problem still persists. Still, the third one said something is wrong with motherboard and they don't have time for investigation, because after placing new battery it would get over heated and discharged very fast. I'm stuck and out of possibilities. Phone is basically new without scratches now, but I can't use it.
Please if anyone want to read my problem above and help me I'd be thankful.
Is this a good question?
