Just recently, within the last couple of weeks, I've noticed some strange things start happening with my phone. It is shutting itself down like 10+ times per day. Usually it is after I am sliding the QWERTY keyboard back in, or after I hit send when sending a text. Also, the battery is losing power very rapidly. When I try to recharge the battery while the power is on, it gives me an edit saying that the battery is too cold or too hot to charge. It's never done that before, and it's not hot or cold! If I completely power off, it will then charge. But obviously I can't use my phone if it is powered off. Not sure what to do.
