My battery life was not acceptable in the weeks after getting the Eris. I had replaced the stock messaging app with chompsms and drained the battery to 1% three times in a row. However, I was seeing about 13% battery drain per hour. I do work in a low service area a few hours per day and suspected beautiful widgets might be pulling too much power. Thursday night, I did a factory reset on the Eris. I went back to running sense and set up my notifications and location settings like I like them. Taking the phone off the charger at 7:15 this morning, I used it as usual throughout the day with 22% remaining at 11:30 tonight. My up time went from ~21% to 13% and my battery drain went down to about 5% per hour. I've had 17 emails, 3 google voice messages, a couple dozen texts, 45 mins of wifi at the office, 45 mins of Robo Defense and minimal phone calls. I'm guessing I've removed a problem app or setting, but havent isolated it yet. Maybe beautiful widgets, maybe the first location settings (use wireless networks) unchecked or maybe it just responded to a fresh factory reset. Either way, I'm thrilled with the improved battery life today and wanted to report. Thanks for the great resource this site is!
