Hello!
I bought a iPhone 6S from eBay.
I charged up the phone and replaced the battery because i tought i have some problem with the battery.
So the simptoms:
I charged up the phone with the new battery, and keeps restarting.
When i unplug the charger and trying to turn on, it’s shows the battery sign only, so I have to “charge” the phone.
When the phone is on the charger, it’s show 100% for a second, and drops down to 1% and turns off.
This is have to be one of the IC? Or something else?
Maybe the screen, or the battery is the issue?
I had the same or similar issue with the old battery.
The old battery is a replacement one with 2200mAh capacity, I got the phone like this.
It’s been restored to factory setting via iTunes and updated to the latest IOS.
Thanks!
