I have the 3500 mAh high capacity battery for my phone. Works like a charm. But it's pretty bulky. So I have been researching ways to improve the life of the OEM battery. I have it rooted so I am under clocking to 426mhz when the screen if off and I have done a lot of the other little things that I have read about. When it comes to bumping the battery, do I have to do it every time I charge it? I've read this shortens the life of the battery. I know I am not the only one looking for the "Holy Grail" when it comes to extending the OEM battery life.
