Why is my battery life draining so fast?

[AC Question]

I have a HTC One Remix. My battery will go from 80% to 0% overnight ( about 8 hours). Android OS and Android System are using most of my battery. What do I do?

Welcome to AC.

Have you tried a simple Power Off and Restart? That's the first thing to try and it sometimes fixes it. But get back to us if no go.
