s21 poor battery life

Just received my s21 on Thursday 18th March, been using it for a few days. i've not even got all my apps setup, only downloaded. And have found the battery drains fast. 
Faster than my 3.5 year old pixel 2 xl. Which is odd. That this old phone with a smaller battery and more pixels lasts longer.
Is this an issue with exynos SoC? This is my first Samsung Android phone and so far I am not impressed.

3hrs 46mins screen on time, 29% battery remaining.
I am using the phone in 60hz. Bluetooth is off, adaptive brightness for the screen. I don't have it really bright, dark mode is set. WiFi is on(I am at home most of the time), 4g and mobile data enabled(i don't have 5g calling plan), no dynamic lockscreen/wallpaper.

What are you getting on on your s21?
Can I return the phone to Samsung if I am not happy? It was bought directly from Samsung online shop.
(UK version s21, Grey, 256GB,)

In that case your battery is doing excellent. Exynos has nothing to do with higher battery drain, the chip is more efficient than the SD part this year. Your battery life is about what I'd expect from the base model S21. It can be improved by a couple tweaks like disabling nearby device scanning, using a fixed brightness and dark mode. You could also limit power usage through power saving to only use 70% CPU if you need more battery life.

In regard to returns/refunds you have 28 days for a full refund from the date you received the phone with Samsung. I'd recommend calling them to arrange the return if you wish to go this route.

Your big problem are Chrome and AOD. Chrome is known to be a resource hog. Try another browser

thanks, i can see that its pointing at chrome, but usage as u can see its showing 30mins, and background 19mins, and i had literally 2 tabs open.
Also the AOD wasnt a problem on the pixel 2xl as a comparison, so i wont be leaving that off.

Report the issue in the members app.

Chrome is broken as hell and Samsung are dragging their feet. The issue is with Google Webview apparently, they've asked me to get in touch with Google to let them know. -_-

Battery life not gotten better. I still haven't setup all my apps yet, so not got notifications for everything I would normally use from my old phone.
2 hrs 35min SOT 34% battery remaining.
I am using adaptive refresh instead, here, And also have changed the AOD schedule to only show between 7am and 2am (while previously AOD was set to show always).

What do you other owners get for SOT?
