I've been on a cruise with my data off for a week. Left my Droid Bionic plugged in all night. Woke up in Seattle with 4G with 20 app updates and some email syncing. I let it download the app updates over 4G (which was extremely spotty and kept disconnecting me) but does this battery usage look correct? I started futzing with the battery profile and brightness once I realized how fast the battery was dying.
I had maybe 1 hour and 20 minutes of life before I started plugging it in for the first time. Didn't seem to have many apps/services running, but whenever I am on 4G it seems my battery just kills itself. It gets pretty warm too, which is my cue to check and see if something is frozen and typing up resources.
My top battery process was Display(25%) and Android OS(16%), then Android System(11%). I use automatic brightness.
