Android OS huge %

[Ihazterbo]

Ok scrolled through the form as much as I could but can't find what I'm looking for so I'm putting up this post.
Battery was at 62% when I went to bed (2am). My phone was dead when I woke up at 9 am.
Says OS operating system was taking up the most. Uh this has never been an issue. What can I do to bring it down?
It's currently being charged.

Please tap on "Android System" and post a screenshot of it.

Also you should disable WiFi when you're not using your device for a long time because that drains much battery.

Now my wifi kept dropping and picking back up last night so I don't know if that had something to do with it. I make sure all apps are closed out and even have an app to tell me if ones are misbehaving.
