HTC One Remix battery draining extremely fast?

[Blackn2020]

I have a HTC One Remix. The battery goes from 90% to 0% overnight with the screen off. My usage shows that Android OS and Android System is using most of my battery. Also, my phone is awake when the screen isn't on sometimes. What do I do?

you can try doing a factory reset.

is there any odd apps that you installed recently or changed anything that might have an indication as to why this is happening?

I've deleted all the apps that I've installed since it started, and I can't think of any settings I've changed. It's still happening.

I am going to just list some things. Not trying to troll but sometimes they help

Reboot? Turn off wifi and/or bluetooth and see if that helps. close running apps from the recent app menu before going to bed?
if not like I said you can always try a factory reset and wait a couple power cycles before making any new calls on battery drain.

It does sound pretty severe though.

I already cleaned my phones cache and rebooted it. I was thinking about putting on power saving mode at night, but the battery life suffers when I leave my phone alone for only 10 minutes or so. I'm going to do a factory reset and report back.
