This is the first phone I've had of this kind (s'appelle "smartphone"), but the battery life is bad when using for email, texts, calls, browsing, etc... when using all day. I don't know if that is the nature of the beast, because I haven't had a phone of this caliber before, but my impressions are that it is a battery drainer. No tech problems at all and it is an all around an awesome phone for any purpose.
