Right , i never posted an actual picture , but i remember very distincly i got 14 h 58 m screen on time & around 3 h screen off time (+ youtube and some other apps after i'm done with Quickedit)

and the battery was at 20% with the estimated time for about 3 h left , unfortunately & i'm willing to admit , i forgot to take the screenshot , shame on me.

and i rarely let my phone battery goes below 20% , so you were right it is a calculated time , but it was the Device care that calculated it , not me , i believe the calculated time would be precise considering the battery has been very consistent & the screen was on most of the time.

About the Quickedit : yes it is not a high processing task , but there is a few things that we need to consider , first , the app doesn't have the dark mode , secondly , i'm typing most of the time & Samsung Keyboard is considered a power hungry for a keyboard app , last but not least , my mobile data (4G) , bluetooth & media player was active in the background , with that being said , i'm not in an attempt to save the battery , it's just me doing my daily task on my phone , even with only Quickedit 5% / hr is quite good i would say , with youtube , a lil bit of gaming , etc i can get 13-14h SOT easily (before the battery reach 20%) but all of those was when i'm on One UI 4.1 , with adaptive 60-90hz i'd say it's possible , i mean , it's hapenned to me , after One UI 5.0 battery wasn't that good anymore , but still can get 10+ hr SOT with 120hz

(still testing , changing a lot of settings back and forth trying to get the most out of the battery @120hz refresh rate)

same phone , same type , same specs , but still a different unit , different charging habits & usage habits , can't really expect to have exactly the same in real life performance / SOT just because of applying the same settings , From my point of view (please don't flame me if you disagree) we should only use someone's preset as a reference & we need to experiment with it by ourselves to find the one that suits well for us & our devices ,

besides , have you try to enabled the Adaptive battery ? if yes , for how long ? it needs time to learn the usage habits and may not work right away , but you should see the result soon enough , what about location & background services ? how many apps do you have on your phone (especially 3rd party app) ? how many apps do you regularly use ? how many apps that need regular synchronization for update & notifications ? how many apps that use Usage data access permission ? any google services / assistant apps ? widget & apps on the home screen ? brightness ?

I have only 48 3rd party apps installed on my phone , all apps that requires / use internet connection in the background are disabled with a Package disabler when they're not in use , execpt for Whatsapp of course ,

no location & asisstant service , brightness is always under 20% except when i go outside .

am i a very light user ? depends on how you define what a very light user really is , yes i have only a few apps installed on my phone , yes i don't use any unnecessary background services , but i always set the processing speed to Maximum when browsing , watch videos & games

my cpu usage is very high , even reached it's max for a long period of time quite often , yet still have a relatively low temperature & battery consumption , the only time my battery drain really quick is when playing games but no heating up whatsoever , sounds like nonsense but it is what it is (see the pic from my thermal guardian)

Anyway , here is the screenshot of my SOT after 4 days of updating to One UI 5.0 (October security patch)

not as good as before (One UI 4.1) but not as bad as the first 3 days as far as i can tell .
