I believe I can unequivocally say that I cannot get good battery life from my X with moderate usage. What I mean by "moderate" usage may mean something a little different than most. But I like to listen to music, browse the web, etc fairly regularly. However, using my BT headset, it doesn't appear that the music app really drains that much battery. I am on 2.2, rooted, using SetCPU to reduce CPU usage at set intervals and my display is set to 30%. I also turn off my display frequently, and the timeout interval is set to 1 minute, 20 seconds with a widget (so that's the max length it stays on). I have GPS and Wifi turned off. However, I do have to keep background data on because I have email alerts pushed to my phone 24/7. Today I have not listened to any music and hardly browsed the web at all. All I have done is worked on updating my home screens. I unplugged at 6:45am and was down to 30% battery by 3:15pm. Any other suggestions to help improve battery life? I'm thinking extended battery, but at this rate, an extra 20% isn't going to help all that much for the money. I'll end up recharging by the end of the day anyway.
