My HTC one m8 is plugged in, and the battery is going down. It's using about -600 to -1100 mAh while plugged in. When it's not plugged in, it's using about -34. This doesn't seem right at all (obviously) I am using the wall adapter that came with the phone. But not the same cord, but I've used this cord for awhile and never have had this problem. I've tried different adapters and different cords. I have cleaned out the charger port. It charges fine when it's off and plugged in. Any ideas? I'm new to this forum so hopefully I can get some help
Thanks!
