My battery stats, Android System is usually at the top below screen. This was the case for A10 too.

I have the same issue, but I think this is not really issue, because battery is fine.
I downloaded docker, installed BetteryHistorian there, checked my bugreports and found that there is no issue actually.
S Health is always in memory and it initiates insane amount of wakelocks, but in statistics I can see this app consumes just like 1% of battery which is not true.
I believe this is problem with native android battery stats, not issues with Asus implementation. I had a lot of phones and native statistics always sucks.
I have a work profile with a lot of applications there and I can't see them in that window, like they not exist. Other software like samsung, don't even support work profile, I can't receive push notifications etc.
So my opinion if idle and screen time is ok, then forget this battery stats.

I have 5-8 hours, BUT
I have 238 apps installed in personal profile
I have 34 apps installed in Work profile
This includes a dozen of messengers, which can't be hibernate in order not to miss notification. And Outlook, which wakes my phone up each 5-15 minutes during business day.
Maybe this is not the best result, I don't know. But with my previous phone Oppo Reno I had 2.5-4 hours of active screen time with battery 3700 Mah. Number of installed apps was almost the same. Scenario (work+personal profile) was the same.
So this parameter, SOT, depends on use scenario. Please show me kinda "flagship" phone with better active screen time.
