Hi all! I have an iphone 6s 64GB. Two days ago it started to tun off. I charge it overnight. Now, two days ago I woke up in the morning and it was off. I thought maybe I overcharged or the charger wasn't plugged in all the way. It wasn't responding until I pushed the reset and as it turned on I saw the battery was fully charged. The phone wasn't hot to touch, only slightly warm. Everything was working fine until the following morning when sane thing happened. I thought it was overcharging and this third night I charged before I went to bed. Then I unplugged the charger and the phone was just lying there for the night. This morning I woke up and the same thing. Off again. Responding to reset buttons. If any has any suggestions I'd really appreciate it. I'm pretty stumped here. Thank you!
