I've had the Droid for about a month and up until about a 3 days ago was very happy with the device. My battery life was pretty darn good for a smart phone. I was getting about 2 full days between charges (if I wanted to wait that long) and that was with surfing the web, gmail and phone calls. Then about 3 days ago I went to bed with around 70% battery and woke up with phone having run out of battery. After recharging I noticed that the sync icon in the status bar was staying on for several minutes which was not happening before. I monitored battery throughout the day and noticed that I was at 50% before a half day passed. So I used the power widget and turned sync off and was back to my usual 2 days of not having to recharge. The only account I have is gmail and it has been static for over a week (No contact changes or emails) so I'm not sure why all of a sudden the sync is working so hard. I beleive it's the sync that's eating my battery since I've never seen the icon sit in the status bar so long and when I turn it off I'm back to acceptable battery life. Up until the battery issue I never turned sync off in the power widget and I'd like to go back to leaving it on. I'm wondering if I changed the "account & sync" setting without knowing it and that is causing the issue. Could someone explain the "background data" and "auto-sync" settings and how they work. If I turn on "background data" the power widget shows that sync is on. I thought I had turned off "background data" and was still able to receive gmail and contact updates without manually retrieving them. Thanks!
