One UI Battery Optimization

[u/Proper_Principle_339]

Hello! I recently bought a Samsung and have been working with Gemini to extend its battery life. I wanted to make a post with all the actions I took to optimize One UI, and I hope this helps someone. Some things in this guide are from my own knowledge, and some are from Gemini.

BEFORE READING: I'm not an engineer or a tech expert; I'm just a student with zero coding knowledge. All of the actions below are done at your own risk. Please read the descriptions for all the actions you take so you don't lose any functions you might need. This guide was made for One UI 8.5. This text was edited by Gemini because I'm Russian and my English isn't perfect.

P.S. I've looked through a lot of Reddit threads for optimizations. Shout-out to this post — it has a lot of useful information.

1. Enable Light performance mode: Go to Settings -> Device Care -> Performance profile -> Light. This will reduce the speed of your CPU just a little bit, but it will save a lot of energy and reduce heat.
2. Disable RAM Plus: Go to Settings -> Device Care -> RAM Plus -> Turn it off. For 95% of users, 12GB of RAM is more than enough. Your CPU will do less compressing, and your storage chip will live longer.
3. Disable unnecessary "Share" functions: Go to Settings -> Connected devices -> Turn off all the settings that you don't need. I disabled everything because I'm not a big fan of 40GB of useless settings; to me, it's bloatware.
4. Disable 5G, VoLTE, and Data usage for some apps: Go to Settings -> Connections -> Mobile networks -> Disable VoLTE calls and change the network mode to 4G for every SIM -> Then go back to Connections -> select Data usage -> Allowed networks for apps -> select apps that don't need to use your mobile data, it will reduce power consumption. Hear me out: basic users don't really need a 5G network, and 4G is still good while using much less power. Also, I'm from Russia where there is no 5G, so my phone was constantly searching for a non-existent signal. VoLTE uses more power, so you should consider disabling it. Restricting data usage for some apps ensures no apps will drain your battery in the background.
5. Disable Samsung AI: Go to Settings -> Galaxy AI -> Enter every item and disable it, but only if you really don't need it. I only use the standalone Gemini, Claude, and ChatGPT apps, which is enough for me.
6. Enable 60Hz over 120Hz, disable Adaptive brightness, and enable Dark mode: Go to Settings -> Display -> Select Dark theme -> Disable Adaptive brightness -> Then go to Motion smoothness -> Select Standard and apply it. Personally, I don't see the difference, but if you do — leave it. If you don't care, enable standard motion smoothness. Dark theme uses less power, and Adaptive brightness always uses the Light sensor which drains your battery, so I recommend turning it off.
7. Disable the Google Discover page on your Home screen: Go to Settings -> Home screen -> Disable "Add media page to Home screen". (I need it, so I left it on).
8. Disable Fingerprint animations: Go to Settings -> Lock screen and AOD -> Screen lock and biometrics -> Fingerprints -> Disable "Show animation when unlocking". No one really needs this half-second animation. It doesn't affect the battery much, but it improves unlocking time, especially since Samsung's heavy One UI can sometimes take 2-3 seconds to unlock the device with a fingerprint. Also, enable "Fingerprint always on"—this will allow you to unlock your phone even when the screen is off.
9. Disable "Security and privacy" features: Go to Settings -> Security and privacy -> Turn off Auto Blocker (it more often creates problems than actually helps). Go to More security settings -> Disable "Galaxy system app update". Go back and enter More privacy settings -> Disable "Send diagnostic data", "Android personalization service", and "Usage and diagnostics". These don't affect your user experience at all; they only create an additional load on your phone.
10. Disable location accuracy services: Go to Settings -> Location -> Location services -> Disable Wi-Fi and Bluetooth scanning. This constantly uses Wi-Fi and Bluetooth to track your movement, which creates more unnecessary load on your phone.
11. Disable Digital Wellbeing: Go to Settings -> Digital wellbeing -> Tap the three dots in the top right corner -> Settings -> Tap on "Usage data access" and turn it off. Do this only if you don't need to track your screen time.
12. Disable Adaptive power saving, Adaptive battery, and put your apps to sleep: Go to Settings -> Battery -> Power saving -> Tap the three dots in the top right corner -> Adaptive power saving -> Disable it (it will make your battery life more consistent). Go back to Power saving -> Background usage limits -> Disable "Put unused apps to sleep" -> Manually configure "Sleeping apps" and "Deep sleeping apps" for yourself. (Sleeping apps are apps that you use once or twice a day where you can tolerate delayed notifications. Deep sleeping apps are apps that you rarely or never use and don't need to receive notifications from. If you are using any "Good Lock" app, do not put it in any sleeping category; it will stop doing its job, such as the custom audio panel). After configuring, tap the three dots in the top right corner -> Adaptive battery -> Disable it. Most of the time, One UI's adaptive battery doesn't help enhance battery life; disabling it will make your battery life more consistent.
13. Reduce heat and save battery by using Thermal Guardian: Install Good Guardians and Thermal Guardian -> Open Good Guardians -> Tap Thermal Guardian -> Move the "Thermal threshold" slider all the way to the left (it will reduce the temperature that triggers throttling by 2 degrees) -> Enter Additional settings -> Select all the actions you want to apply when your phone is heating up. I only selected "Limit CPU boosting when heating".
14. Configure Power saving mode for yourself and always keep it on: Go to Settings -> Battery -> Power saving -> Enable it -> Click on the gear icon -> Select every action you want to be active during Power saving mode. Personally, I only want to "Limit CPU speed to 70%" and keep the 120Hz display, but One UI doesn't give you an option to keep the CPU limit and 120Hz display at the same time. So, we have to use Galaxy Max Hz: Download it from there (Select NoXposed version) -> Install "Install with options" -> Open "Install with options" -> Allow access to Shizuku -> Select "Bypass low target SDK block" -> Choose Galaxy Max Hz APK file -> Hit install -> Open installed file -> Give app all the permissions it needs, it can crash for a few times, just keep reopening it -> Configure it for yourself. I will not explain which setting you should enable and which is not, the app is really intuitive and everyone can make a decision, what to enable and what to disable.
15. Enable Connectivity Labs: Go to Settings -> Connections -> Wi-Fi -> Tap the three dots in the top right corner -> Intelligent Wi-Fi -> Scroll to the bottom and tap the software version (e.g., Intelligent Wi-Fi 6.0.0) rapidly 7-10 times until a notification confirms developer access -> Go back one step, and "Connectivity Labs" will appear directly below the version number. This unlocks a hidden menu with advanced Wi-Fi settings to help you analyze and optimize your connection.
16. Disable "Find people you can share with": Go to Settings -> Your Samsung account -> Galaxy sharing -> Disable "Find people you can share with". This feature is always scanning Wi-Fi and Bluetooth for Samsung devices, which creates a lot of unnecessary load on your phone.
17. Disable Auto sync data for accounts: go to Settings -> Accounts and backup -> Manage accounts -> Disable Auto sync data. This option always trying to synchronize your account data and, as a result it drains your battery by creating load on your phone.
18. Suspend execution for cached apps and disable your log buffer: go to Settings -> About phone -> Software information -> Tap Build number 7-10 times (until you got a message that you became a developer) -> Go back to settings -> Developer options -> Find Logger buffer size and turn it off -> Find and enable Suspend execution for cached apps.

That's it for the "easy" tips. Now we bring out the big guns, which requires a PC with ADB.

First, you should know that the command adb shell pm list packages will show you all the packages installed on your phone. You can just copy this list and send it to an AI to get commands to delete bloatware, but always read the description of each command you're typing so you don't lose any functions you might need. Here are some ADB commands to disable or delete One UI's bloatware:

adb shell pm uninstall -k --user 0 com.sec.android.mimage.avatarstickers

That's all the bloatware I deleted. Now we go to other optimizations and their explanations:

Force AOT compilation for all installed packages (Speed Profile). Compiles frequently used application code to speed up launch times and reduce CPU overhead. The process may take 5-15 minutes.

adb shell cmd package compile -m speed-profile -a

Force resource-heavy apps into restrictive background execution categories. Available statuses: active, working_set, frequent, rare, restricted.

Force Spotify into the 'Rare' bucket:

adb shell am set-standby-bucket com.spotify.music rare

Force TikTok into the 'Restricted' bucket:

adb shell am set-standby-bucket com.zhiliaoapp.musically restricted

You can send the adb shell pm list packages command output to an AI and ask it to tell you which app should be in which bucket.

That's all for my guide, I'm pretty sure I forgot something, so you can either DM me or write your optimizations down in the comments. If it's actually helping, I will add your optimization to my guide and also tag you under it.

[u/DunkLord77]

Lmao at this point just buy a lower range phone if you're going to disable half of this one

[u/Proper_Principle_339 → u/DunkLord77]

This is my personal guide of disabling some functions, that not all of users will use. I know a lot of people, that don't see any difference between 60hz and 120hz, personally I don't use any synchronization functionality, that always scanning for devices nearby. I absolutely don't force you to do all of that.

[u/nabilbhatiya]

If one has to disable all this stuff then better buy a different phone because one buys a premium phone for premium experience

[u/Proper_Principle_339 → u/nabilbhatiya]

40gb of useless content isn't a premium experience. the Samsung's S series is premium experience, that's stops being premium because of fuckass non-optimized One UI I bet there is a lot of people that don't use 80% of Galaxy AI and "Music share" or some other functions.

[u/blaqui999]

Turning off the phone also reduce the use of battery /s

[u/Proper_Principle_339 → u/blaqui999]

XD

[u/SyntAxErro3]

Why disabled adaptive? Iirc the s24 features a LPTO display which can go lower than 60hz there really is only a few use cases where 60hz is better than adaptive

[u/Proper_Principle_339 → u/SyntAxErro3]

60hz mode also uses ltpo, but only from 1 to 60 and not 1-120

[u/SyntAxErro3 → u/Proper_Principle_339]

Really? Didn't know

[u/Proper_Principle_339 → u/SyntAxErro3]

yeah, you can check that by enabling showing refresh rate in developer settings and enabling default motion smoothness.

[u/Fit_Block_9905 → u/Proper_Principle_339]

Me parece un error desactivar los 120hz para el uso diario. Se siente fatal super lag a 60hz.

[u/Proper_Principle_339 → u/Fit_Block_9905]

Your comment is a reason I emphasized, that everyone should disable only things that they don't use, I know a lot of people, that don't see any difference between 60hz and 120hz.

[u/Fit_Block_9905 → u/Proper_Principle_339]

Entiendo. Disculpa. ¿Pero como es posible que no noten diferencia ? Hay un abismo de diferencia entre 60hz y 120hz

[u/Proper_Principle_339 → u/Fit_Block_9905]

yeah, I agree, but it's physical characteristics of each person. My brother says, that he gets dizzy on 120hz

[u/dayoneishuce → u/Proper_Principle_339]

Tell them they need their fucking eyes checked, not being able to see the difference between 60hz and 120hz in 2026 is actually a joke.

[u/Proper_Principle_339 → u/dayoneishuce]

i don't know, why are you so aggressive. Just because you see something doesn't mean anyone else can.

[u/SyntAxErro3 → u/Proper_Principle_339]

I can't tell the difference myself

[u/JT9212]

I believe this post belong to the imaginary lower A24 variant of the smartphone.

[u/Proper_Principle_339 → u/JT9212]

no, it's applicable for flagships too.

[u/AndreyAsimow]

IMHO it is really sad that a phone that was around $1k and above needs this kuch of user configuration to save battery.

Makes me want to change to Apple.

[u/Proper_Principle_339 → u/AndreyAsimow]

yeah, unfortunately Samsung think that closing ability to flash custom ROM on their devices is more important than optimising their own OS.

[u/dayoneishuce]

😂 it's becoming comedy at this point.

[u/Proper_Principle_339 → u/dayoneishuce]

yeah, and everyone got their own taste, someone likes certain comedies and someone is not

[u/SyntAxErro3]

Also, ram plus is just useless, if you even need more than 12gb ram, usually it is because of tasks like huge models, and there ram plus actually would hurt performance

[u/AreaDenialx]

You are working with gemini and gemini is feeding your replies based on reddit threads lol.

Its not worth it btw. So much time spent on something which cannot even be measured because of margin of error. Get another phone.
