I was initially disappointed in the battery life of our two MyTouch 4g phones, and I do wish they would last longer under heavy use. But after having the phones for a couple of weeks and making some of the changes inside the settings (none drastic) the battery life has greatly improved.
Photo below: My wife's phone has been on and used for 1 day 5 1/2 hours and still has 56 percent battery life remaining. We have the data set to auto select, gps off, bluetooth turned on and off as needed and USB debugging set to on. Her screen is set to auto brightness. Wifi off. She doesn't play with her phone, she uses it when she needs it. It is used with our business and she used it pretty heavy this morning receiving phone calls.
My phone on the other hand is down to 54 percent after 11 hours but I have been playing with it most all day, listening to music and using wifi for the web.
