Hi there,
Do you have Task Killer, Battery Booster, Antivirus or similiar apps?
If you have any of these apps, remove them all.
Boot your phone in Safe Mode and use it for a few hours and check if something will change for the better regarding your battery life.
Maybe some app/apps causing all of this?

Cheers.
Feel free to remove it because you do not need Mcafee or any other antivirus apps, especially if You are downloading apps from Google Play Store.
