Battery

As a Beta software you will get some issues.

Possibly not with the beta software, but app compatibility.

Make sure all apps are updated from the Google play store and galaxy app store.

Go into battery in settings and see what is using the battery more than it might 

It's also possible that it's gone into a battery learning cycle for a few days and will sort out after that

Keep an eye on the beta forum for others that may have found a solution 

Also provide feedback in the relevant section on the beta forum 

Feedback left, im all updated and im a light user in general. Usually charge once every other day.... 5 hours off charge 50% gone. Nothing seems to be using that much in the battery info so its definitely some sort of background process. I get logs are constantly being generated and sent home but the 8.5 beta i never experienced anything like this... I would have had to have a video playing for hours to experience battery drain like this

Ive had no issues here recently ive had some other issues before this beta recently ive gone into apps on the settings and reset app preferences its meant every app I then loaded asked if I wanted notifications but my battery endurance has increased so much. The other thing you might want to do is go to the dialer and type *#9900# and reset battery stats. If you have auto blocker on you will need to go to settings then security and turn it off first. Make sure to turn it back on after.

for me its even better tho
