iPhone 6s Phone came in not charging. Replaced port twice and does show that it’s charging but never increases percentage. Replaced the battery, same issue. Will now randomly shut off as it seems as though the batteries aren’t connecting thus the possible reason we aren’t seeing an increase in percentage.
Maybe there is something wrong with Power chip… Did u tried to DFU and restore the phone to iOS10.3.1 first? Please let me know! Tks :)
