I'v had this phone since the 31st, The spare battery tends to last longer because its very first charge wasn't interrupted. in the morning i used pandora on my hour+ long nj transit ride to and from school. I used the map and gps to find directions to this store I stopped at on my way home as well, and made a few calls.... and logged into and chatted with trillian im a few times through out the day. oh and yes email, +2 push gmails, facebook, twitter, myspace, and samsungs social networking app is set to sync just to give you a idea of what else is running. the battery life varies... but I didn't bring my spare with me so I was very impressed with it today in particular because of everything i managed to get done on one charge.
