Galaxy S6 edge plus battery drainage

[Robert 1_2_3_4]

I also have a Galaxy s6 edge plus and my battery is draining very fast and i went in settings and my cell standby drains 65% of the battery. Can somebody please help me to fix this problem really fast?

Welcome to Android Central! High Cell Standby battery usage usually means poor cell signal. How's yours? If you can't find a graph for that in the settings, use GSam Battery Monitor, and show us screenshots.
