iPhone 6- last night, I was still using it at 3%. I let it go dead regularly and don't charge it if it's above 20%, most of the time.
that phone is 3+ years old!!!!!!! what in the hell do you expect out of a battery that has been charged and discharged a minimum of 1,000 times. surely more, during the last year, you have probably been charging and discharging more than once a day.
