i am unfortunately very OCD about the battery and it is ruining my iPhone experience. i even hate myself for it but i just cannot stop. i literally check what may be the cause of the percentage drop in the battery settings every half hour or so and keep restoring my iphone to new every month or so because i feel like the phone isnt running as long as it could. same reason i got location services and background refresh turned off
also there seems to be a general issue with my 6. just yesterday it turned itself off at around 18% telling me to charge it and when i plugged it in it started to charge at 19%
Dude, just TURN OFF battery percentage. You are worrying too much about it.
