I bough another OEM battery on ebay and now when i'm trying to charge it for the first time the notification light blinks red and green with an exclamation point through the battery. Then after a few seconds it goes back to solid red charging fine then does this again. The battery seems to be charging though..it went from 2% up now at 8% I recharged the battery which came with the phone many times and it's fine. Never had problems with it. So It cannot be the HTC charger going bad. Light is always solid red when charging. The battery and phone is not overheating. Battery temp is 27-29c. Phone feels cool to the touch. I tried to take out the battery, hold down the power button for a few seconds put the battery back up..same result. Did I get a defective battery?
