Hey guys,
So a month after the launch of the Galaxy S21 Ultra, what is your battery life experience? Give us your feedback and numbers.
Please mention your chipset (Exynos or Snapdragon) and post a screenshot if possible.

Personally, I'm pretty satisfied with battery life. I usually get a day and a half with around 9h of SOT. I have the Exynos model and my screen is set to 1080p with standard motion smoothness. Bluetooth is always on and I use 4G most of the time. All other settings are set to default.

Samsung Galaxy S21 Ultra
Can't complain, I get around 5 hours SOT a day with 30 to 40% left in the tank.

That said, I am stuck at home all day on WiFi, so sure that will decrease when I'm out and about with location on and 4g/5g but still pretty decent.

Exynos, QHD, 120hz, active 2 connected all day, some debloating and Bixby routines to switch to 60hz for some apps, turn off location/NFC/4g at home and sync/AOD on when charging

How is you Phone radio usage so low. Mine is always way higher. Does that mean the signal is bad??
I think bad signal is definitely a factor. In my case, I stay at home most of the time (remote work) or at the office and in both locations I have a very good signal. Also my carrier doesn't support 5G yet, only 4G.

Standby for me has been amazing.
Ikr, even with Bluetooth on, I lose barely 3% at night.

Had Exynos S21 Ultra that i didn't like the battery life of it. I had barley 4h of SoT.

I send it back to Samsung and got a Snapdragon HK version and i am getting 4.5h with the second full charging. I hope it gets better in a week or two.

It will get better. I was like you.
Then I reset my phone and didn't use smart switch and after couple of days I am getting now around 1h SOT per 10% with bluetooth and 4d enabled. Full resolution and adaptive framerate and sometimes I switch to 96.

    5 hours SoT in 22 hours. 18 minutes of Chrome and 42% battery. This seems odd....any ideas?

    Chrome is bad... Use Samsung browaer
    Am seeing 7hrs SOC, with 40hrs of total stand by time.

    Iam seeing this every 2 to 3 days mate with sot over 9 hours :) and had about 22-24% left there :)

    Should I try to factory reset without using smart switch this time? I´ve tried to put 80-90% of the apps in deep sleep, but the battery doesn't get better

    This last cycle, the smartwatch was connected for 8-9 hours
    Report through Samsung members as an error report so they get logs from your phone. If everyone here does the same thing Samsung will have to send out a software update to fix.

    So is the whole thing about apps coming across via Smart Switch causing battery drain real ? Tempted to factory reset to see if it improves battery but reeaallyyy don't want to if it's just a myth .....
    I don't know if it works and I was considering doing it but...


    A few days ago I went in and disabled backround data usage for facebook/chrome and also went into developer options and for the hell of it set background processes to at most 4. I've attached the result which is no doubt the longest I've ever gotten out of 1 battery charge of any phone I ever owned. Almost 4 days with over 7h SOT is insane.

    Since I'm WFH 99% of the usage here was browsing the web or chatting on messenger as you can see from app usage but I was able to almost get to 4 full days. I've attached a screenshot of basically the same usage profile before these changes and you can see the battery life was significantly worse. I'm not sure which one of the two above is more to thank but I literally did no changes except for those from a settings perspective. I'm still on AUB6 which is showing the latest firmware for me as a US SD888 user. The only other thing I could think of is an app update helping a lot but I really doubt that given I don't recall any release notes or a huge update for the main apps I use.

    First screenshot is post changes, second one is from a few days ago before I did the above changes (I also posted it earlier in this thread but useful to have side by side)

    Man that's incredible ! Can I ask how you actually do those processes ? (Disable back ground data for certain apps and set background process to 4 I mean - hell that bit I don't even know what it means haha)
    You can disable background data usage for apps by going to settings>connections>data usage>wifi data usage. Then click on any app you don't want using background data and toggled "Allow background data usage" off. This particular setting isn't really what was saving me battery though because I reset the background process limit to default and battery drain increased noticeably again.

    As far as the background process settings, you have to enable developer options to see it. You should be able to do that by going to settings>about>device and then tapping build number like 5-10 times IIRC. In developer options this setting should be towards the bottom called "Background process limit" and you can set a limit of up to 4. Do beware that every time you restart this phone this setting itself reverts back to default which is the standard background limit (see note below on that). It's also noteworthy to call out most people recommend against doing this but I personally saw no change in my phone's functionality by doing it.

    I don't use a whole ton of apps so the impact may be different if you rotate through a ton of apps since I believe this setting will kill a lot of them from running in the background simultaneously. I might try running gsam with it off vs on and see what it is specifically changing but I'm pretty sure it's this setting because I restarted my phone the other day (which causes this setting to go back to default) and noticed a noticeable increase in drain again.

    I'm by no means an Android expert when it comes to stuff under the hood but has anyone ever noticed this much of a difference using this setting in the past and is it to be expected?
