I know that smartphones are battery killers but this is my only gripe with my new Droid Eris. I've had the phone for three days and the battery is back and forth. The first full day I had the phone it lasted till about 2pm on a full charge. The second day it ended up lasting longer till about 6pm. Now on the third day it's 12:45 and it's at almost 30% with not much use. I know there are open threads about this already but I hope this battery starts to get better over time like my Storm2 did. Sorry to complain because this is the best phone I've had since I left Blackberry.
