[General Topics] OktaviAnabelle:
I have (had) so much going on lately , its been a busy day that i almost forgot to share my settings , i'm so sorry. so yeah i hate to say this , but this post would look like a thread within a thread , just as i said earlier it is quiet a lot , i use almost all the "Recommended Settings" stated in the OP so these are just some "adjustment" & a little bit of addition that i choose based on my personal preferences .

so here it is :

S21+ > One UI 4.1

5% battery/hour of Screen On Time

- APPS -

247 apps Uninstalled

196 apps Installed (system & 3rd party)

56 out of 196 apps are Disabled (system & 3rd party)

Stable & No Bugs (so far) | No Heat

Missing features that i notice are : Bixby , NFC , Quick Share & Galaxy Wearables

( the apps list in the preset are including 3rd party apps , if you see some unknown package name please skip it )

Some adjustment are in regards to these matters :

Battery life , UI smoothness & My personal preferences (feel free to adjust it to your own preferences)

- Wallpaper : in the attachment > my phone screen looks almost completely black it helps to reduce battery consumption

- Color Pallete : only 2 colors black & grey > it is all because of my wallpaper

- I keep my home screen as clean as possible , no widget , only 2 apps Phone & Settings

- Find my device : Off

- Face recognition : Off

- Fingerprint : Off

- Settings > Data usage > Data saver On

- I left Auto restart at set times disabled i restart my device manually only when it is necessary

- I use Samsung Internet Browser instead of Chrome , it has better dark mode , UI , privacy , customization & consume less power

- Advance Features/Gestures : Double tap to wakeup , Double tap to sleep , Swipe screen for screenshot

- I keep System UI & One UI home battery setting unrestricted

but changed the Android System & Samsung Keyboard battery setting to optimized

this was in the OP before.

- All 'Gestural Navigation Bar' apps battery setting are set to restricted , i use buttons for navigation bar

- SmartFPSAdjuster app battery setting set to unrestricted

- Camera app battery setting set to restricted

- I dont use any 'assistant' apps

- If you have the option to change your screen resolution you might want to change it to FHD+ to save even more battery life

FHD+ & WQHD will look exactly the same to the untrained eye

- I have only 2 social media apps installed , Whatsapp & IG

Whatsapp is the only one that i need an instant push notifications on , so i Disabled Instagram using Package Disabler Pro when its not in use

- Auto rotate : Off > Only turn it on when necessary

Or you can do it manually by turning on the Rotate button on navigation bar options.

- Notifications :

Advanced settings

Notification History : Off

Notification reminders : Disabled

App icon badges : Disabled

- Google Settings :

Autofill

Autofill with google : Disabled

Phone number sharing : Disabled

Sms Verification : Disabled

Find My Device : Disabled

- Safety & Emergency :

Send SOS message : Disabled

Emergency Location Services : Disabled

Wireless emergency alerts : Disabled

- Developer Options :

Debugging

Disable adb authorization timeout : Enabled

Networking

Wi-fi scan throtling : Enabled

Tethering Hardware Acceleration : Enabled

- DumpSys :

Go to phone > keypad > *#9900# > Delete dumpstate/logcat & Batterystats reset

- To save even more battery *Optional - Use with caution*

Developer Options > Quick Settings developer tiles

Enable Sync , Sensors Off & Window animation scale

these 3 settings will appear in quick settings panel & you can turn on&off these services from there

turn off Sync will turn off auto Sync data , so you dont have to go to Settings > Accounts & Backup > Manage account to turn Sycn data off

turn off Windows will completely disable the windows animation

turn off Censors will disable your phone censors like gyroscope for example , so auto rotate wont work

Hidden screen mode settings :

Head to Settings > Display > Screen mode

Select 'Natural' from the available options

Adb Put System | screen_mode_setting 0

change the value to any number you want to choose

0 for "AMOLED cinema" 1 for "AMOLED photo" 2 for "Natural" 3 for "Basic" 4 for "Vivid"

I personally use 0 , if you aim for a battery life go for 0 , 2 or 3 , Stay away from Vivid.

To apply the changes go to Settings > Display > Screen Mode > Don't select anything just go back

if you use 0 or 1 the name will be change to AMOLED cinema or AMOLED photo , if you use 3 the change will apply even though the name remain as 'Natural'

but if you check it , neither Natural or Vivid are selected.

Why AMOLED cinema : The best one , it is more bright , sharp & colorful than Basic & Natural but not as colorful as Vivid.

- Optional , but i recommend it

DNS Adguard is probably one of the best when it comes to blocking Ads on a system-wide , it's free and works without even installing any software to your phone , but it might causing more battery consumption , im not sure ,

the theory is that you need to be connected to their server in order for the blocking to work , it keeps sending a request for any internet activites that occurs on the device that may cause more battery drain , logically a phone that doing nothing will have better battery life than the one that constantly connected to a server but again im not really sure about this ,

so i decided to install Disconnect Pro For Privacy & Performance , the app is build exclusively for samsung devices , it blocks all trackers , ads & malware through Knox .

just like Adguard , however , it runs NATIVELY meaning that it has 0 impact on the CPU power & Battery life , it is as good as AdAway which you can only use on a rooted device

the app also shows you what apps are the source of privacy invasive tracking , Google Play Service is at the top of my list by tracking me more than1000+ times within a day , with this app you dont have to connect to Adguard server at all times , it's in the Galaxy Store for about 40$ , a little bit pricey but it's worth it

for now i use Adguard DNS only to unblock some blocked internet content when i'm surfing the internet.

- Adjustment in Adb Optimization settimgs -

SetEdit is highly recommended when it comes to editing the settings from

these 3 categories Global/Secure/System

Put System | lockscreen_minimizing_notification 1

Put System | lockscreen_show_shortcut 0

Put System | lockscreen_sounds_enabled 0

Put Global | boot_count 0 (the value will increase everytime you reboot your device , i personally change the value back to 0 every time it count to 10)

Put Global | phenotype_boot_count 0 (same as the above)

-this counter is only logged since your phone has been last factory reset , this data is stored in settings database ,

wiping data through factory reset is the only way to delete this stored logged data , fortunately i have

access to adb so i just keep revert the value back to 0 whenever i want , or you can even delete the whole string not only the value ,

if you dont care about this minor boot data statistic stored in the database then i suggest you to leave it alone .

but every time the value changed back to 0 the next booting process seems to be much faster ,

it might be a placebo effect , i dont know , but ive been doing this for about 2 months & no negative effect so far.

As for the Battery

Put Global | animator_duration_scale 0.25

put Global | transition_animation_scale 0.25

put Global | window_animation_scale 0.25

- 0.25 is lower than 0.5 , phone feels snappier , no unnecessary animation = less battery drain

Put System | dim_screen 1

Put System | screen_brightness 8 (for indoors only , for outdoors you can adjust as you like)

Put Global | low_power_back_data_off 1

Put Global | sem_power_mode_refresh_rate 0,0-1,0

Put Global | sem_power_mode_refresh_rate_cover 0,0-1,0

- I dont know about these 2 settings , it was there since i use SetEdit to check the Global table

the value was 0,0-60,0 before , i changed it to 0,0-1,0 out of my stupid curiosity and i get a better battery life ,

no negative effect so far , i dont know what could happen to your phone if you try this , but i can guarantee you that it won't make your 120hz screen device to run on 1 FPS , you could always change the value back to the default anyway.

ADAPTIVE BATTERY MANAGEMENT : ENABLED

Now , this is where things gets really interesting to me .

my true intention was to get a great battery life while keeping my device performance as good as possible because i play games too.

and i want my notifications to be uninterrupted by this 'Adaptive Battery' feature because i have Whatsapp too.

just by looking at the name it is crystal clear that Adaptive Battery may help to extend my battery life , but i have read in many many article that it actually not good for my phone.

So i just kept turn this feature on & off for a couple of days , and yes my notifications seems a little bit strange , sometimes it comes too late , or even didnt appear at all on my status bar

it turns out that the feature put my apps into a sleeping state , but i have no issue with my device performance or perhaps it was just unoticed .

but again i have heard that with Adaptive Battery enabled , the battery will restrict the power that are given to the system so the phone runs worse

with the feature enabled , but i decided to kept the Adaptive Battery to be enabled then i've come to realize that in Developer Options > Standby apps the 5 state buckets options is only applied if the Adaptive Battery enabled

while when the Adaptitive Battery was set to disabled all apps was on the Active bucket in Standby apps settings & cannot be change it will remain on Active ( i put the detailed description of every state in the attached file )

App standby buckets help the system prioritize apps request for resources based on how recently and how frequently the apps are used , Based on app usage patterns, each app is placed in one of five priority buckets

the system limits the device resources available to each app based on which bucket the app is in.

as soon as i know about this , i looked to which bucket my Youtube was in , and it was on Active

based on the description of this Standby state feature , the system doesnt give any resources restriction to my Youtube , but Youtube was in my list of Deep Sleeping Apps in the Device Care battery setting and was closed for a couple of hours i force stopped it.

at least it should be on the Frequent , Rare or Restricted bucket but it was not ! then my stupid newbie brain was like

" Okay , these two settings/features are clearly have the same purposes , but they're aren't that related , then why don't i just use BOTH "

So , for the sake of my battery life , i ENABLED the Adaptive Battery options , put my unused apps to Deep Sleep in the Device Care & put them on the Restricted bucket state in Developer Options.

Tips : - if you want the app to connect to the internet simply put them on 'Working set' state

- When you open an app it'll automatically move to the Active state , the system does not give any resource restriction to that app , so if you really care about your battery life just put it back to the Restricted state everytime you close that app , it'll automatically change the state but it takes time , so just do it manually , it took less than 10 seconds for me to do so .

Yet , i still have something on my mind that bothering me all the time ,

And yes it was about my notifications and device performance , even though i didn't notice any performance issue on a daily basis activities i still worried about how my device performs in a high processing tasks such as gaming or editing high quality videos

i can't help it , i need to find the solutions at least my 'own' solutions.

and this is what i did :

- Notifications :

Simply put the app to the Never Sleeping Apps would help , but enabling Adaptive Battery will activate the Standby apps bucket , and if the apps are in the Frequent , Rare & Restricted

the system will give some restriction for the apps to connect to the internet (according to the description)

therefore there is a chance that it will interrupt the notifications from the app , FORTUNATELY , you can just stop & prevent the apps from entering the Restricted apps Standby bucket by simply go to Settings > Apps > Choose which app > Set the battery to Unrestricted

I did it to my Whatsapp , now it's working just fine i got the notifications on time (Please take a look in the attached file)

- Performance :

- Game Optimization Service & Game Booster , these two apps have many Permissions that may ruining my device & game experience

for example : both apps have a SET_PROCESS_LIMIT permissions there is no point to have this two services , so i just stopped them from running by disabling them with Package Disabler Pro.

I dont uninstall them i'm afraid that it would left my phone unstable.

- I installed Thermal Guardian , part of Good Guardian app , the app lets you control your Thermal Threshold , i choose to have a higher thermal limit it can increased the limit for up to 2°c which is the maximum allowed by this app , +2°c is not a big deal but still boost the performance and helps to maintain it when the device gets a little bit warm .

- Put Global | enhanced_processing 1

- Put Global | restricted_device_performance 0,0

- Put Global | sem_enhanced_cpu_responsiveness 1

We all know what these 3 settings do to our device , FORTUNATELY enough

enabling the Adaptive Battery doesn't change the value of these settings .

Phone runs smooth , even better than when i first bough the phone , battery life is amazing , no performance issue , never heat up even when i do some multitasking stuff , the only time it gets a little bit warm is when playing Mobile Legends (moba game just like Dota , beautiful graphic , very popular here in Asia) and the warm is very acceptable.

If i'm right , then my phone is running on the Peformance Mode all the times with no battery drain whatsoever while Adaptive Battery setting set to ENABLED so that i have access to the Standby apps feature in Developer Options & get even more settings to extend my battery life .

If i'm wrong , then i don't know what sorcery is this .

1 thing that i learned , every changes & adjusments take times to shows its results . For example : when i disable RAM plus & GOS for the first time , right after the phone was rebooted , it feels worse , much much worse , my UI was a little bit lagging/stuttering , the temperature feels hotter than before , the battery seems to be drain much faster , but what i did was just use my phone as usual , charge my phone as usual , give it some time to adapt to the new settings , as the time goes by it gets better , it keeps getting better & better & now all works great as i wanted.
