Hey all,
I bought an S22 Ultra a few months ago and was disappointed with the battery life I got, even after I waited fo Adaptive battery to kick in. I expected a hell a lot more with a 4nm chip and more efficient LTPO Adaptive refresh display. So, I did some investigation and I think the main culprit it background services hogging battery. I tried out a few settings and finally found the following 2 steps to help me drastically improve my standby drain and battery life. Thought, I'd share them here, so anyone else who has terrible battery from the S22 series could try this out to improve their battery life.
Here is what I did;
1. In the Developer options, there's an option called "Suspend execution for cached apps". Please enable this! We all have to accept that Samsung devices have a lot of services running in background which hog the battery and all poorly optimized for efficiency. As some other posts have claimed this setting just shuts off all unnecessary nonsense running in the background. After enabling this setting, my standby drain is incredibly minimal (about 2% overnight, utit used to be 6% or more). I still get notifications from messenger apps (see next step).
2. In "Background usage limits", put all rarely used apps to Deep sleep or even just sleep. Here, make sure to put all your messenger apps to never sleeping to get notifications.

NOTE: I don't see any performance hit with the suspend cached app setting. Adaptive battery should actually do this (in a less obtrusive way) , but for some reason doesn't work as good this setting in disabling background usage. If anyone cares to explain this, I'm all ears 😅

Do you keep adaptive battery on
Yes. I have left it on. When I disabled it, I got slightly worse battery life. But, the game changer is suspending cached execution. I see immense difference after enabling it 😀

One thing I don't understand is, in Android 12/13, if we put apps to Deep sleep and keep adaptive battery on, I don't know if this will affect the Deep sleep configuration 😅

I am testing this right now, and after almost 1 day of ussage, i think that battery has improoved quite a bit.
18h 28min usage, out of that 4h SOT, and i have 37% left battery. , so thanks for this. One more thing that i did is, i turned off RAM plus. I think 12 GB of RAM is enough.

Hello, can someone tell me how to disable RAM plus? I want to test if this improves battery, but can't see an option to disable it, only to select how much RAM you want to assign. I'm in Android 12, still waiting the update. Many thanks.
See for adb command

Tested it for a bout a week, battery is a bit better, but in some cases system UI gets unresponssive or totaly lags out. Would not recommend this option as it is not stable. Also in some calls people didnt hear me, so I had to repeat the call, than it would work fine.

    Tried it for a few days and went back to the default setting. Phone performs better in default setting for me. Battery life was never an issue for me either.

    I followed this stopping cached apps since 10 am, it is now 7 pm, so far, so good, all notifications ok, no delays
