Help Suddenly battery time stinks!

[mikeb33]

I've had the Seidio 3500mAh for about a year and it has been great. Starting a few weeks ago, I can't get past 5-6 hours on my battery. I don't think I've changed anything or installed anything for some time now.
I usually leave it plugged it all night and take it to work, leave GPS and blue tooth turned on all day. Maybe 1-1.5 hours of talking, not much else.
Is my battery just crapping out? I tried leaving it off all night while plugged in.
I am considering a complete restore, but would like to avoid the hassle if there's no reason to think it would help. Ideas?

I would assume your battery is crapping out. I believe most of the batteries that are used in the evo are good for 300-400 full charges. I would get a cheap battery off of amazon or newegg and try that before wiping completely

I was looking at the battery and found it is slightly swollen a bit. That back cover doesn't quite snap on all the way. I guess I found the problem.
