Had Droid Charge since Aug 2011, no problems until few weeks ago. My battery life went from charging once a day to needing a charge every 4 hours. About this same time, @Email would mysteriously lose my password and lock-me out of my corporate account that had been working perfectly since August. I deleted the corporate account, re-attached the account, changed it from auto-push to poll every 15 minutes, still had battery problems. Verizon sent me a new phone 1 week ago. Thinking the @Email with my corporate account was the root of my problems, I'm now using K-9 for all of my email - love it with seemingly no problems. I do need all of my contacts & calendar synced with my corporate account so I synced only my contacts & calendar of my corporate account and NOT any email or any other accounts. I check the battery use and find that @Email is killing my battery - sitting at the 2nd highest application with 20% of my battery use. Meanwhile K-9 is sitting at 2nd to last at only 2% of my battery use. I changed the calendar & contacts on my corporate account to sync once a day, still no change. How can @Email be using so much of my battery, if it is only syncing contacts & calendar once a day?!? I've checked with IT at my office, they say it is a device issue. I've bump charged my phone. I'm running out of ideas. Any ideas on how to fix this problem?
