I am not happy with the battery life of my captivate. today I had school from 4pm to 10pm. at 4pm my battery had 100% juice I checked the time during class a couple of times I didn't really use it. Them after class during my one hour break I listened to my music for an hour and thirty minutes and used wifi for about thirty minutes and my juice ran out!!!! I couldn't even use my music player anymore. In total I used my phone for about two hours and the rest of the time it was in standby. I turn off the wifi when I'm not using it. I use a regular wallpaper,I'm using the lowest brightness setting, and I constantly stop running apps. The only apps I leave running are 3g watchdog, fancy widget, and batt stat. my fancy widget refreshes every two hours ONLY if wifi is available. Why does my battery kill soo much juice what do you recommend I do?
