[DISCONTINUED/CLOSED/END OF SUPPORT] Samsung Galaxy One UI - Optimization Guide

[KayserXDA]

In case somebody has Galaxy A52s, this is my preset of deleted apps I've been running since Android 12 with some small modifications. Usually pretty non-invasive if you don't like stock crapware, what's left "installed" is then either disabled or used as primary app.

I also use Galaxy MaxHz in combination with some of adb config tweaks from here, and my SoT is usually 8-9 hours on WiFi, games included.

What adb tweaks did you use? And did you follow the Guide from the first page?

What adb tweaks did you use? And did you follow the Guide from the first page?

Yes, I've fully used Recommended settings, as well as adb settings values which are now listed as "Level 1" and "Level 2" (only Level 1 was used in my case) on the original page, however, even there I usually change/leave on some features I prefer myself, such as double tap to wake.

For optimizing the apps I use, Galaxy App Booster also is something I do after every update.
Some minor but beneficial "tweaks" to save battery can also be achieved with Galaxy MaxHz app, such as force setting some apps to 60Hz instead of 120Hz (eg TikTok, less motion-demanding games) as well as setting up PSM on screen off and "Quick-doze" mode which prevents unnecessary battery drain during sleep but doesn't impact notifications during the day.

Also, setting up Adblock to block ads on your apps with DNS or adblock app can be very beneficial to reduce both traffic and unnecessary performance (thus battery) wasted on loading/displaying these, and saves you time

Are these just for wi-fi calling?

Facing this same issue.

The explanations online range from encryption to combination use of WiFi and LTE for HD calls, but I haven't experienced or noticed any issues with regular conversation without these packages

Thank you for letting me know, I now have a better understanding on the 2 options.
However, I still do not fully get what "restricted_device_performance 1,1" is.

1. What is it setting exactly with those 2 numbers? I remember reading that somebody set it to 0.7,0.7 and somehow that was a sweetspot but for what exactly? I don't get what this does.

2. If 1,1 is the default, how come someone else's default was actually 0,1 and not 1,1?

Thank you for helping me better understand what these commands do.

1,1 is NOT 1.1
1,1 designs 2 values for 2 different situations, 1.1 is a fixed value set

Hi guys! I have not done any tweaks or upgrades to my S21 Ultra for about 7 months (debloated with this topic ADB script version current, current as of then - and as it disabled software updates - did not update the phone software since then). So, Questions:
1. Is S21 Ultra debloat list maintained, or topic author moved on to s23?
2. For S21 Ultra - if I update - will I see worse battery life? How was your experience with new features/latest version of debloat lists?
3. How do I do so many months of updates? Restore all apps, then update, then debloat with latest lists?

Thank you so much!!

1. Author is still an S22 owner, and does its best to set a general thread for all Samsung phones users.
2. Off topic
3. Check OP

Take a look at this comparison. To my knowledge, gsmarena is a reliable source for phone specifications.

Compare Samsung Galaxy S23 vs. Samsung Galaxy S22 5G - GSMArena.com

www.gsmarena.com

As i said, larger body with the same screen, so less screen/body ratio.

I haven't checked the default value (it may vary). But note it only applies when power saving mode is enabled.

How come then, that according to OP, the default value is 1 which would mean that Limit CPU speed by 70% would be enabled by default which is clearly not the case.

Default value is 1,1 , not related to powersaving mode to my knowledge. People have tried setting it to 0,0 which resulted in more performance with more heat.
Feel free to test/try for yourself and report back with the results

@Hamid Chikh from a battery and performance standpoint what do you think about precompiling all packages with the speed profile?
"adb shell cmd package compile -m speed -f -a"

“Magic Trick” of Galaxy App Booster

I happened to try an app called Galaxy App Booster that is a part of Galaxy Labs released by Samsung. It claims that it can optimize all apps on device and boost the overall performance by 5% to 15%…

itnext.io

According to a few posts on reddit (in a nutshell) in exchange for a few gigs of storage space it is supposed to boost performance by precompiling packages that would otherwise need to be interpreted at runtime.

We have discussed, and tested all of this a few hundred pages back

 

[Hamid Chikh]

Did anyone test out 1,0 ? Maybe it will limit the CPU to 70% without power saving mode that way. What else could the second digit mean ?

Impossible, that's called "light performance mode" and is controlled by
sem_low_heat_mode in global

I'm sorry in advance if my following questions aren't suitable to be asked here. I'll be getting a S23U soon;

1) Is it safe for me to use the preset on the phone, are they the same on every model?

2)Do I have to enable/restore all of the apps that have been disabled/uninstalled if there are major OS updates in the future?

Thank you!

1) this config is suitable for all phones, especially samsung phones. If an app isn't present in the phone, it will be dismissed, if it is, it has already been uninstalled on other devices without any harm. Feel free to test yourself, as i don't have an S23 in my hand.

 

[Hamid Chikh]

Won't need to, s23 ultra battery is a different animal compared to S22 ultra

Can't get worse with less app installed in my opinion, but hey, i debloated a google pixel so to each their opinion

 

[Hamid Chikh]

Only second full charge. Multitasking, a little bit of gaming, 2k 120hz, auto brightness, installing like 50 programs at once. Zero lag, no issues at all. I'm pretty sure It will improve even more.

With or without optimisations yet ?

 

[Hamid Chikh]

which app should be deleted on s23u to have better autonomy?

There's a preset in OP

 

[Klaudas]

With or without optimisations yet ?

With some tweaks from your first page. I think with deeper debloat you would get even better results. But personally sometimes I'm using "samsung cr*p". So I'm only debloating, disabling things that I really don't need to use.

No it's not published anywhere. Just found it when I decompiled services.jar and smart manager apk
This is how it is being used in services.jar. It is similar in smart manager but just obfuscated.

They must have corrected afterwards. At the time I wrote my previous comment, the S23 had 1cm3 more screen. But looking at gsmarena's battery test of the S23, I'd gladly let them have 1cm3 off my S22's screen for that amazing battery life!
