Android Alliance

I am with sprint and i have noticed my battery draining faster than few days ago, the cell standby is approx 25%.
Any idea on how to fix the problem?
I already have greenify and clean master.

Thank you

Delete Clean Master. Use All In One Toolbox -- Install "auto tasks" plugin. Greenify is good, run it often. Also put apps to sleep thru the settings panel -> Device Maintenance. Use the shield too, to disable bloatware/unneeded apps. Lastly, uninstall any apps you aren't using or that are junk.
