Hello, I am having battery issues. Sometimes a percent lasts an hour, and sometimes it lasts 5 minutes. The battery is sometimes (rarely) good, and usually drains. Things like turning off WiFi and 3g and managing the screen brightness I know. I have a rooted HTC Evo Design 4G. I also have DU Battery Saver Pro and Greenify installed. What can I do to make my battery last a while, and be consistent with it? Thanks so much!!
