Chosen Solution

Hello everybody, The iphone 6 plus battery started to drain, I tried everything from changing the battery and chargers to changing the U1700 ic chip which actually worked! But unfortunately I couldn’t connect it to a computer nor plug it in a charger, it works temporarily then turns off with apple logo loopinf when plugged in, i tried changing the ic chip twice and the problem hasn’t been solved, anyone has any solution for this frustrating problem?

Its possible You damaged additional components when replacing the charging ic have you tested the Components next to the charging ic for damage?

i have iphone 6 plus charging not working i change u2 ic but not working please help me
