I found that not using push mail and just having outlook check e-mail every 2 hours saves a lot of battery. I can go the whole day and still have 70% left. This includes making phonecalls, texting, surfing, and listening to music for atleast an hour while at the gym. Obviously if you need push service, this isn't feasible. Otherwise, this is a free way to have your battery last longer.
