At the end of a day's use, do your battery usage stats indicate anything abnormal? If you are not sure, post a screenshot of the stats here, so that we can try to diagnose. You'll need to register as a member in order to do that, but you'll be welcome.
Of course it may simply be that you need a new battery.
