Solved Device Does T Charge But Doesn T Drain Iphone 6

Chosen Solution

I have an iPhone that I have replaced the battery in twice and each time when the phone is plugged in it doesn’t drain the battery but it doesn’t charge either. I have tried a variety of different chargers and they all do the same thing. Any help would be appreciated! Thank You!

More than likely Tristar chip/U2 IC issue, replace and see if it works. Requires board level microsoldering. :-)
