May be a rogue app. Go to Settings -> Battery. It should tell you what is using most of your battery. Downloading the GSAM Battery Monitor app may also help. Good luck!
First thing I would do is pull the battery. Restart the phone.
Then check to see if you have an system OS update trying to download. Menu>settings>about device>software update>check new
