General Battery life experience

3%. This was after 2 hours of walking.

That's quite good, given the reports from other users here who suffer from heavy battery drain attributed to said wakelock

Today I did 13.5k steps and CameraService_worker shows 372 wakelocks.

Firmware version? Look at mine when AI did 20k

This is wrong (Incorrect way of measuring) statistic. First full charge device and then use device and then set default to "charge" and then show screenshot.
Currently Your device showing battery drainage in minus bcoz of custom setting.

Ok, thanks for letting me know. I will charge full and see.

I had Galaxy S21 Ultra with (Snapdragon 888) Hong Kong version in about 3 months, I did not like the battery performance of that phone at all, the SD888 seems to be very power hungry and I sold it. Later I bought (in Sweden) the S21 Ultra with Exynos 2100 and have that phone since 2 weeks, I can tell that I am surprised how the battery performance is compare to the Snapdragon model, also all around performance I can't see any differences.

Just to let you know, I had S21 Ultra with Exynos 2100 when it was launched back in January but I decided to return it back and get the Snapdragon model which I thought would be better in overall performance! In the first two months yes, Snapdragon was a bit better but now with more stable software updates I can tell that Exynos 2100 is performing better at least in battery life department!

Look at the attached screenshots from my battery usage..

* 50% WiFi & 4G.
* more than 60% usage of Bluetooth headset.
* Adaptive power saving on automatically when needed.

Looks better than mine. I ended up with less than 3 hours screen time at 40% battery. Did a lot of walking yesterday so the camera wake lock drain was noticeable.

Have you done any system clear cache and app repair as mentioned earlier?

Also a good thing to know, I did NOT add any app to force sleep in the power management section, I let everything to be done automatically, the only thing I did to enable Adaptive Power Saving option.

 

[nightoooo]

I have 19% battery life left.. Time to charge the phone..

* Exynos 2100 chip (256GB variant)
* Last time charged: 1 day, 13 hours ago!
* The SoT is: 5,12 h
* The phone possibly can last: 1 day, 17 hours
* 50% WiFi & 4G.
* more than 60% usage of Bluetooth headset.
* Adaptive power saving on automatically when needed (kicked in at 40%).

Adaptive power saving will turn your refresh rate to 60 most part of the day, so it's easy to increase the battery life doing this.

It's needed when you ran out of juice, you can't see a big different when this is enabled so why not use it? Also, it's giving me much better battery life than i had in the Snapdragon variant.

8 hours on 4g/4g+ 15 hours and 30 min on wifi
wqhd 120hz
30 min using bluetooth (tidal)
only 4 hours of SOT =/
exynos AUE1

Any suggestion to improve it?
I did a factory reset after march or april update, I'm not sure which one
Recently cleared cache and no improvements

Your overall usage seems good but people are more interested to see the SOT (screen on time). If you tap on the blue graph it shows you the total SOT.

Whatsapp drains too much battery when using mobile data
Thinking about factory reset one last time to check if the battery life gets better

Have been getting even worse battery life (and estimates) than this.
Debloated carrier (ZTA) and other Samsung nonsense today, wiped cache, optimized apps. Going to leave it on standby during the night, from 100%. I'll be asking for a replacement if it drains on standby or if my morning usage almost kills it (turning off Wi-Fi, using only mobile data, GPS on, paired with active watch 2, moving around, listening to music etc).

Seriously, why in the world a device that gets 8h of SoT with gaming and YouTube would struggle to keep up with browsing the internet and music??

Whats your average SOT per charge? I moved from ZTA to ZTO on Day one to get rid of Claro bloatware
Was thinking about to back to ZTA rom, to see if i get any better than this

I'm testing that today. On idle I went from 97% down to 93 or 92% in the morning, in a span of 8h or so.

With my usage today so far (GPS, Bluetooth and mobile data on, browsing the internet with Spotify downloaded songs playing), I'm getting an estimate of 6h of SOT, for 100-0. To me, that's unacceptable. My phone came in the box with no battery from the get go, I think I got a defective unit.
