battery percentage dropping, from 50 to 1
Quick question :
i have an iphone 6s.
battery is sometimes going from 60 or 50 procent to 1 procent.. the 1 procent can bee for several hours..
sometimes i don't have this problem .. strange..
I measured out the battery and that was good. I checked the life of the battery and still above the 90 procent , ( what i figured after the measurement)
what could it be? the IOS 10- 11 "bug" draining the battery or giving faults ?
TIGRIS or TRISTAR?? could that be a possibility ?
what would i do? : hard rest to reset the battery?
Thanks in advance
