Help! Why is my Android system draining my battery?

[AC Question]

I have a Samsung Galaxy Note 5 and when I check gsam it says my main battery usage is android system. It has used 42% of my battery life. I never had a problem until the last week but in 2.5 hours my battery has drained 30%. Why is this happening? What can I do to stop it?

Welcome to Android Central! Does this clear up after a reboot?

No it doesn't.
