Hello all, I am starting my own thread because none of the old ones hit on exactly what i am about to say. MODERATORS PLEASE DONT RELOCATE THIS POST!!! i really want others to find this thread and it will get lost in the sea of other posts. Ill start from the begining. Got my evo- charged it for a few hours until light turned green. Got about 5 hours out of it. Read online and did all of the tricks others were talking about, started reducing functionality and backing down syncing. removing apps, stopping automatic startup- even rooted with damage control, still didnt see much difference. at that time i was getting about 5.5 to 6 hours out of it with moderate use. Did the "conditioning" noticed no real change IF THIS SOUNDS FAMILIAR THEN READ ON So i decided to try something different. I charge the phone turned !!!OFF!!! from around 15 % to full (green light) . Turn the phone on til green light (usually takes about 15 minutes) Thats it I now get at least 12 hours heavy use. I did not do that process last night and im 4 hours off charge -light use and am almost dead. so i really think this works. try it out and post back if it did or did not work for you. again i use phone until 15% or less. turn phone off. place on charge until i get a green light. turn phone on. wait for green light. unplug charger. enjoy lasting battery.
