Samsung S21 Series - INSANE Battery Optimization in 1 STEP!

Hi folks!

With latest update to Android 12 and OneUi 4 Samsung introduced a new feature in developer options called "Suspend execution for cached apps". This option should freeze apps when cached and unfreeze them once removed from the cache or killed. Frozen apps will not use any CPU cycles, reducing power consumption for misbehaving processes which might attempt to run while cached.

When this is enabled you should be able to fix the battery drain and drastically improve the SOT - Screen on Time of your phone - so let`s check it!

Test please and share your results as well!

I personally wouldn't mess with developer settings.

As it is people are having issues with Android 12 .

For me I have found keeping all settings on adaptive or auto gives the best battery life as the phone learns your usage patterns.

Is this really a thing then ? It's intended purpose? I'm a bit reluctant to mess with it till I know exactly what it does

Hi Andy,

honestly I was hoping to get better improvement but it seems that it is very much linked to the usage pattern of the user - with my usage I am still getting a very good consistent SoT - somewhere between 4.30 hours with super heavy to 6.30 hours with normal usage.

Well I use my s21 from 85% to 20 and I always seem to hit around the 5 hrs sot mark so I'll just leave it as is thanks
