I have a MyTouch4g. I have attempted to permanently root the phone. Did not work, not did I mess up my phone. The instructions all over the internet on various ways to root the phone are ridiculous and not worth the effort due to the complications involved. So I thought getting an extended (1700 mah) battery would work. I got the Trexcell 1700 from amazon.com. It sucked. I am returning it. DOES ANYBODY, HAVE A CLEAR SIMPLE SOLUTION to making the battery last??? I have the gps and wifi off, and my settings are minimal. There has to be some type of solution to either simply root the phone without being a rocket scientist OR a BATTERY THAT IS BETTER. It's 2011, not 1993, why aren't there simpler solutions????????
