S21 FE battery usage from 5G and 120 Hz (self.samsung)

The S21 FE doesn't have an LTPO display, so you can run it at either fixed 60 Hz or fixed 120 Hz; there's no dyanmic scaling. For those of you who own one, what difference in battery usage do you notice from running the display at 60 Hz vs 120 Hz?

Furthermore, the modem in the SD888 is not the most efficient around. How does you battery life compare when you have 5G enabled (and actually connect to a 5G network) vs staying on 4G only?

Do you somehow disable background refresh during that time? Because for me DND just silences notifications, but they still get delivered.

I check the option "hide notificatins from notification panel"

You will still "receive" notifications but they will appear on the notification panel when DND is inactive and not when it's active. Sorry, I expressed myself poorly in the previous comment, it's not that it will straight up block notifications from coming, it's more like putting you phone in silence for some time.

The reason I think this works is because the phone keeps vibrating/ringing whenever you receive a notification and that also consumes more battery.

Other than that, yes, as I said in the first comment I put some apps to sleep/deep sleep as well, depending on my use of those apps (idk if that's what you mean by background refresh).
