@Hamid Chikh from a battery and performance standpoint what do you think about precompiling all packages with the speed profile?

“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.

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 ?
[General Topics] blackrubi:
Apparently, the second number is useless.
[General Topics] nolan91:
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!

[General Topics] Klaudas:
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.
[General Topics] bodomfan:
No but I know a few that do, mine arrives next week
[General Topics] bodomfan:

[General Topics] Klaudas:
S23 ultra. I've got on Friday
[General Topics] Emre67511:
On my galaxy S9 there is and medium power

On my old galaxy S9 there is a medium power saving mode and a maximum power saving mode. Both have a seperate option for limiting the cpu to 70%. The second digit is probably a leftover from back then.
[General Topics] blackrubi:
Yes, I too have seen that in previous models, however, the option in the phone's settings was removed.
[General Topics] nocio:
I'm giving another chance to debloating and this is my results so far. This is second full charge with latest preset.

Looking at the S23 Ultra, and how it improves on the S22's shortcomings - I wish I had gotten the S23 instead
[General Topics] Klaudas:
If you have snapdragon version don't even bother. If you have exynos only one big thing is noticable ant that's battery life. Some other things are better but they didn't changed that much(maybe better stabilisation and videos in the night worth mentioning).

I've used developer options from the first page, did some light debloat and now I'm getting at least 8hours SOT no matter what standby I'm getting (usually around 24hours + 8-9hours SOT).
[General Topics] bodomfan:
What did you debloat
[General Topics] Klaudas:
Samsung dex, chrome and similar programs
[General Topics] DrRazee95:
which app should be deleted on s23u to have better autonomy?
[General Topics] Thronius:
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.
[General Topics] nocio:
Haha thank you i guess 😁

That's with dual SIM, half of the time I'm on WiFi and other is mobile data.

Wired thing is that sometime I got pretty high battery drain and that's one time in a two week so I don't bother with that. For device that is 1 year and almost 6 months old this is good battery life and most of the time I'm draining battery to zero percent and charge it to 100% while it's turn off and when i turn it on I keep it for about 30-45min more on the charger. I didn't apply any tweaks except debloat.
[General Topics] KayserXDA:
What adb tweaks did you use? And did you follow the Guide from the first page?
[General Topics] Thronius:
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 :)

[General Topics] Klaudas:
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.

[General Topics] blackrubi:
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!
[General Topics] blackrubi:
Also, I'm not entirely sure if this has been mentioned before as this thread is 340+ pages, but here are some tricks I use to increase my Exynos S22's battery life with bixby routines or whatever the routines are called nowadays:

1. Automatically turning on power saving when I have a battery hogging application.

IF: Application is open: Tinder, TikTok, YouTube, etc. -> Turn on power saving mode -> turn it off afterwards

2. Automatically enable plane mode during the night as this decreased my idle overnight drain considerably.

IF: Time: 1am - 7am -> turn on airplane mode -> turn it off afterwards

Let me know if this is something that helps you.
[General Topics] Mozie:
I'm not sure whether I understand this section right, so let's say I got my brand new Samsung phone, first time booting up, I should setup fully offline? So not logging in with Google nor Samsung, fully offline set up, when the phone is done booting up afterwards connecting to WiFi > log in to Google / Samsung > install apps .. and so on?

If I understood it right, what's reason behind this offline start up? Because you're logging in to Google and/or Samsung anyways?

Thanks for clarification
[General Topics] lolli.filippo:
Simply because restoring data via Google or Samsung backup could make the system unstable. A fresh configuration is a safer and cleaner way to setup your new phone

Also checking for system update before debloating and installing apps is recommended
[General Topics] serene_sky:
If you have new phone, just start up, don't log in to any account, turn off sync, apply preset to debloat, apply some adb command, tweak,...

When you feel eveything is fine, restart your phone, now you can log/sync accounts you need, also check for system update or install new apps

Cancelled for now, one of these commands causes my BT to go HS. Just factory reset (3rd time today trying to find the culprit) and i'll just debloat without any ADB optimization and see if it's the problem
[General Topics] Hamid Chikh:
How do we turn this off !!
[General Topics] Klaudas:
Most disabled, uninstalled apps are basic ones. I mean you can disable/remove them from settings. Nothing to crazy.

My system settings are from first page except:

Reduce transparency & Blur is disabled.

Adaptive Battery is enabled.

Additionally in "Intelligent Wi-Fi" settings:

"Prioritize real-time data" is disabled.

"Detect suspicious networks" is disabled.

"WIFI power saving mode" is enabled.

I'm using "Galaxy App booster"(once in 1-2 weeks).

Phone is super smooth right from first boot and battery is amazing without any optimizations. Right now I'm using "protect battery" feature for charging up to 85%. Even with that I'm always reaching 6-7 SOT pretty easily with 10-20% percent left. 2k, 120hz, auto brightness all the time, 4G/wifi.

Hi, you're welcome. That option seems to be for exynos version, you can still enable "high" processing mode under battery.
[General Topics] eyeatoma:
Okay thanks., but it's my understand that high processing mode actually causes higher battery drain and heat.

Also, I was curious why you said to turn off adaptive battery, which helps optimize apps and reduce battery drain.

Just wondering because both of these options seem counterintuitive when compared to all the other settings are in the effort to reduce battery drain.

Thanks for clarifying.

It's not all about battery life, we want good performance too. With all the Debloating and optimization we do, we can let ourselves enjoy some good performance, even if has a hit on battery life, since it's it's negligeable with all the tweaks we do.

Exactly, because the S23U has already great battery life and is snappy smooth with One UI 5.1, I'm not sure whether this optimization is needed. I thought probably the only need would be disabling/unbloating some apps.

1. So you didn't use the preset for unbloating, but disabled/removed from the phone's settings?

2. Did you only adjust the settings under "I - RECOMMENDED SETTINGS" of the first post in this topic? (with the exception of some that you mentioned)
