My battery usage is saying that my display is taking up 45% of the battery while Android system is only 15% and others are less than 10%. How can that be! I put the brightness on low, less than half. Probably about 15-20%. I put brightness settings all low, use advanced task killer, but the battery still goes down pretty quickly. If i go on facebook for 1 minute, it will go down by 10%. If i listen to music for 15 minutes it goes down by 15-20%. This is way too fast. I only get about 7 hours with minimal usage (check facebook here and there, listen to 10-15 min of music before and after school, text a little) It barely lasts throughout the school day. What is goin wrong? Could installing advanced task killer and not the advanced task killer for FROYO be the problem, b/c i just found that app....but that has nothing to do with the display. What to do?
