Hi, I get 9h SOT after 3-4 days of using my S21 Ultra Exynos (since I received it) and 2 full days since last charge. Attached screenshot. I am happy so far and I think SOT will further improve in few days, after the system settles down and the battery reaches full optimization. What do you think? Is it good or bad? What about your SOT? ;)

After just 1 charge, i have this SoT (6 hours 32 minutes) with S21 Ultra Exynos 2100. I think it gonna be even better within a week or so.

4G/3G = about 50% of the time
Battery Save mode (It kicks in only when the phone gets a little of juice)

Is this on WQHD or 1080p?

That's insane SoT, i could never reach it, i guess everything depends on how we use our phones, but you did not sapre in anything, gaming, web browsing, videos, etc..once i did have 8 hours SoT but that was because i just watched YouTube videos the whole day lol

Got the phone on 29, coming from note 8 it's insane and when I still have old device I can see the difference side by side.

tuesday afternoon got my s21 ultra.
yesterday i decided to test battery with multiple format between 60hz and adaptive 120hz with and without power saving mode and with and without dark mode.
***** if asking how to power saving mode with adaptive 120hz :
turn off power saving mode / make screen standard 60hz / than select adaptive 120hz BUT DONT APPLY / go to battery / power saving / apply / back to display / apply 120hz . this trick from s20 ultra i know it and work with s21 ultra.

● here my what i turn on and off depending to my need .

-wifii ONLY
-wallpaper home screen dark / lock screen samsung default animation .
-WQHD+ all times
-brightness level manual 50%

-bluetooth ON connected to galaxy watch 3
-No any call during this test ( used home number to call in case need )
-Iam not a fan of gaming , no app game in my mobile.
-All app need puch notification NOT optimized , other app put in sleep.
-Puch notification : lbci news ( its local news app ), tweeter, xda, whatsapp , facebook , messenger , YouTube vanced , saraf lebanon ( its local currency app ) , lebanon prices ( its local currency app ) .

    And that's even with Chrome munching your battery for 15 minutes of use, nice
    I generally close out apps when I know I'm putting my phone down for a bit. It's a habit from older phones.
