Why does my tab S9 FE battery drain weird and fast?

[Dlgkfls]

I bought it 2 months ago but I haven't used it much because of work and stuff so I mostly use it on weekends porbably for 2 or 3 hours max. I activated the battery limit to 85% too and after I disconnect it goes down to 84% in a few minutes and stay there for a while. The tab loses 5-6% too when I just leave it be for a whole day without use (wifi off, lowest brightness, etc.) can someone help me if this is normal or the tablet is faulty? Thanks.

Hey @Dlgkfls.

This seems to be normal. Please be advised that system apps and settings are still running in the background, so it's normal for the battery to drain by around 5% throughout the day.
