I bought a new Razr M (model XT907) for my wife earlier today. We got home from the Verizon store and it was working fine. She noticed the battery was very low so we put it on the charger for about 90 minutes. The battery completed died (while still on the charger) and now wont turn back on. Its completely dead. Ive tried plugging it in on various outlets around the house, and using multiple chargers and even a car charger, and nothing happens. No power, no light, nothing. Im obviously going to take it back to Verizon tomorrow, but is this a known issue with this model? Anyone else have the same problem? Again, this is a brand new phone. If this is a recurring problem with no known fix I wont keep it, and will get her something else. I have a Droid 4 and have never experienced anything like this. If anyone can offer any help I would appreciate it. Thanks!
