i used to have the evo but i sold it cause i wasnt happy with it. battery sucked! that was the only reason i sold it and it was a little to big in my eyes. but i have been pretty happy with my epic's life. i use it through out the day. not alot of phone talking but messaging and face-book and a little music and downloads. but i look at battery use and its like at 71% i have been using the android power controls and have it low when im inside and everything. but idk why it says the screen uses like MOST % out of everything. i mean like by 5 or 6 times more. so if anyone could help me out and give me a reason thanks.
