and battery usage depends upon the apps' activity and background processes and checks.. and network connectivities .... and more over battery capacity.
my phone has 6000mah .. i use it whole day in single charge.
Rite I am also using s21 ultra with Exynos 2100 and I will get around 5 to 6 hrs SOT on 120Hz FHD resolution. Once i had got close to 7.5 hrs SOT. The chipset is good.
Max 4 hrs sot ..Looks like either hardware or OS is not optimized . Also throttling is there frequently and you'll notice wildly unpredictable performance & benchmark scores .For what's supposed to be a Topend - 1 device it should have been better .Let's hope next update fixes these issues
Update : I suspect many of the pre-installed samsung apps / bloatware could be the cause for battery idle drain.Many of them running in the bg .. There are nearly 200+ samsungapps pre-installed 🤦. Could samsung pl reduce the no of apps in the next update
