Huge battery drain on Galaxy Note 20 Ultra

[Belushi7]

My Note 20 ultra (exynos) is currently draining battery. Noticed the major culprit from battery usage analysis to be what is labelled "call log backup/restore" (image in the attached comment below). I have  disable this app, restricted background battery usage but it defies all that and still continue to use battery. I lost 10% battery in 4hrs overnight during standby. Anyone with a solution?

Hi Belushi7, Could you please let us know the place of purchase of your Note20 Ultra.

It’s recommended to optimize battery usage time by setting optimized power mode, adaptive power saving feature or adding unused apps to sleep depending on your usage pattern. Please note that usage time may vary depending on your device settings and operating conditions.

Bought my device while in Nigeria. That shouldn't be a reason for the battery drain. I implemented all your suggestion immediately I got the phone. Been using only Samsung Note devices for the past 8years, so I know. The reason I shared screenshot of my battery stat highlighting the suspicious sys app.
