Anyone have battery issues with their Vivid? Over the past month I have noticed that my quality of battery life has declined. I used to be able to go to 6pm without having to charge my phone. I keep it plugged into the charger at work if I listen to music. However, the second I take it off and close out of programs, etc - my battery starts to go. I had it charging all morning. went to lunch and came back, it's at 45%. It's ridiculous. It's worse than the Aria and Inspire 4G. I don't know what to do but it makes it difficult if I have to go some place and my phone is dead within a few hours. Should I just buy a new battery or something?
