Iphone 6S Shuts Off At 80 Iphone 6S
Chosen Solution Just replaced iphone 6s battery with ifixit iphone 6s battery replacement kit and guide. I followed the instructions including draining battery and charging it fully. The iphone shuts down at about 80%. It will not turn on until it is plugged back in to a power outlet with the apple charging cable. its possible that the battery just needs to be calibrated but after a few charging cycles and the problem is still there i would consider contacting Ifixit and letting them know and they might send a replacement battery....
