Hello, I have tried to repair an iPhone 5. The iPhone has gotten a new charging port assembly, new battery and a new lcd. I did the repairs and booted it. It was working fine. But now I have discovered a weird flaw. Everytime you let the phone die , the battery is dead. Dead as in broken. I can’t charge it after the phone died but I can charge it while the phone is active. I thought that I had received a bad battery so I received a new one but same result. Does anyone else have a clue on how to overcome this? Thanks in advance
The U2 IC on your main board is fried. I can tell you weren’t using an authentic apple charger. Your aftermarket one killed your iPhone. The U2 IC is the charging IC, it controls lock button, charging and a few other things. Unless your very good with microsoldering, it would be easier to get a new logic board. P.S. The batteries still work, you just need to charge them :)
My iPhone 5 replacing new battery when closing all the smoke coming in phone at speaker side why???
