Starting recently, my Sprint HTC Evo (1st Generation) began draining its battery either while plugged in or while shut down. Examples:
1. I turned the phone off with a full charge when I boarded a plane and when I turned it back on about 2 hours later, it had 15% charge.
2. Last night I plugged the phone into the charger and it said "70% charged". When I woke up and checked the phone (while plugged in), it said "Charged" and the battery icon was fully green. As soon as I unplugged it, it went yellow and about 10 seconds later said "Battery at 15%. Charge battery" (or something like that).
Both of these issues have become chronic. I need to either do a restart or pull the battery and hard boot for it to actually hold a charge. I have read other strings and some notes:
1. I have tried multiple chargers, multiple outlets, and even just using USB to my computer
2. Once I reboot the phone, I can use the exact same charger and get the phone to charge and hold its charge. So it is not a dead battery nor a bad charger issue.
Any help is appreciated.
