for battery life, you can install juicedefender. it turns off all your radios periodically. your text and push email won't be "near real time" anymore. your email was pull by a set period anyways. otherwise when you are at your desk or car, just plug it in to charge... at the rate i run mine, i can drain it in under 2 hrs depending on what i'm doing. when i limit myself to regular user mode i can get about 45 hours out of it...

the battery drain comes from powering that huge screen and wifi and obviously this is a new phone to you so you've been playing with it alot.... lol
