My wife and I have both had this phone, since January. She was leaving hers plugged in overnight usually, and after about two months the battery died. The MetroPCS rep told us that we shouldn't leave the phone plugged in overnight, because it over-charges the battery!! We ordered a replacement battery from them, but it's on back-order and no knowing when it will ever come in. We got a 1400mAh replacement from Ontrion, which worked fine, but she left it plugged in overnight last night, and now it is dead too!!
This seems like a defect in the phone's charging circuit, but I don't know what I can do about it.
I was thinking of getting one of those high-capacity external batteries for this phone, and using THAT device to charge the internal battery in the phone. Will that work??
