iPhone 6 battery drain
My 2 year old iPhone 6 (not 6S) loses 10% battery per hour regardless of use. Only way to stop it is to power it off. It use to only drop 3-4% overnight while I slept. Now it won't last overnight without at least 80-85% charge and I wake up with a near dead battery. I hate leaving my phone plugged into a charger so much. Can't be good for the battery's long-term life.
I've recently replaced the battery and restored to vanilla iOS 10 with only slight improvement.
The dramatic change happened several months ago after leaving my phone plugged into my wife's non-apple car charger for a two hour drive out of town. We later realized that this same charger was responsible for destroying her iPhone 6+ battery just a month before (her phone was still under warranty and apple replaced it). I figured replacing my battery would bring back the old usage capacity but it didn't.
I suspect some other component in the power system was damaged by the defective charger. Something between the dock connector and battery.
Looking for suggestions on other replacement parts to try.
Appreciate any help,
Nathan
