I didn't put my phone on the charger last night because it was at like 75% and usually it holds a charge over night. I woke up this morning to find the battery was dead. So I'm charging it now to try to get it at least to 50% or 60% before I go to work. It's annoying because my phone has never done this before, I don't know how the battery drained like that when I wasn't even using it. This phone isn't even that old either. So I'm wondering if this is just a one time thing or of this is going to continue happening a lot. This phone has one of those batteries that I can't just take out and replace so if the battery is bad I'll need a whole new phone.
