I would update to the latest software as someone else mentioned.
Also, look through your settings and see how many apps are autorefreshing in the background. Turning these off made a pretty big difference. I only left the GPS apps on. Emails being constantly fetched may be an issue too, consider changing to push to fetch (hope I got the term right) so it only refreshes when you actually check your email.
