Also See this thread for charging best practices. If you are not charging it correctly you could be damaging the battery

Also check if the GPS is on!.

That will deplete the battery in less then 10 hours, and with other functions on, it can be less.

If GPS is on, also check the settings for the activities if the GPS is on for them also.
