I have tried several things to improve the battery life of my droid Charge including: manually killing running applications, have wifi turn off automatically after no activity in a short time, loading an application to manage the power better. As time goes on, I have found the battery life to be pathetic. One of the reasons I bought the Droid Charge was that it supposedly had more run time life than others. I have found the idle time power usage to be pathetic. I do have a backup battery, but I am beginning to wonder if you need 2 phones if you have a smart phone. One which has a battery life to perform as a phone, and the other a smart phone with its capabilities but an unacceptable battery life. Charged the phone yesterday and after the charge I only accessed it briefly last night to clear some mail, and then this morning after being idle over night with only 13hours it only had 23% charge from 5 minute use the night before. Am I missing something or is this supposed to be acceptable. If it is, Samsung should include a secondary cheap phone with its smart phone so you can still use and make phone calls. I do have a spare battery, but I did not think I would need that just to go out for awhile and make some phone calls and web access. They need to fix this problem by cleaning up the problem or providing a longer life battery.
