Others aren't experiencing battery drain with the same version so it has to be a combination of your apps and the latest version.
I would recommend that you deny as many apps as possible from auto starting with the auto start manager in PowerMaster. You find it in settings -> battery -> PowerMaster
After this, you kill all apps and monitor your battery life. If it seems ok, then allow a few more apps to auto start, monitor the battery life and do the same process until you find the app that you're having an issue with
