I'm usually on 3g. I don't live in a 4g area. My battery was at 40% last night when I went to bed and at 40% this morning when I woke up. I had the phone connected to wifi and in airplane mode. I also removed a couple of widgets. I understand there are certain things I can do to increase battery life. I just don't understand why I lost 25% of battery two nights ago with the same things going on as I had on my Droid X2. My X2 never lost 25% in a night. I actually had more widgets and apps running on my X2.
