mine is terrible. 4 hours (1 hour of music w/ screen off web browsing for ~15 minutes total email for ~15-20 mins and a whole lot of standby time and im at 60 % already... i cant even get through a work day on standby. I run like 2 widgets.. but there are a retarded number of services on this phone that are always running... if i cant sort this out im tossing it and going back to sprint.
Reboot and see if you're still at 60%. I can easily make it through a day of moderate use.
