My battery keeps draining fast on standby

[Ethan2008]

I use a s21 ultra

I don't know why but my battery drains quite fast when on standby unless I turn on power saving mode which I kind of fine annoying that i always need to to do that

I have turned off most push notifications and only a few apps uses the location 

Could anyone help me with this?
