All, Ok, admittedly my first day with the EVO 4G went horribly. The reason- my battery lasted from 8 am to 12pm. I was aware that the battery would go fast but shocked to see it actually do it. Yesterday I played with a few settings. I disabled the Sense UI and installed Launcher Pro, Adv Task Killer. I noticed a big difference in battery usage with LP running than I did with Sense. It used a lot less juice. I then installed Adv Task Killer and have it closing all apps when the screen goes off with the exception of Gmail, Messages, and Voicemail. Huge difference. Started with a full charge yesterday and with decent usage (surf, wifi, camera work, 4G - thanks to widget) by the end of the day I still had 49% battery left. This morning I had 44% left. Much, much better. I know many people say that Adv Task Killer bog their handsets but I have yet to notice any lag. I'm sure Launcher Pro is much better on battery as well. So far so good. As this is my first Android phone I think I am doing ok. I am now using my iPhone 3G as an iPod. One question- I notice that Amazon MP3 seems to run even when I have never even opened it. Should I delete it or what? Any more advice?
