Was on the portal and noticed this:
Hey everyone,
So, I was experiencing significant lag as we all do from time to time, and decided I was going to get to the bottom of it.
After tracing and debugging for hours, I discovered the source of 90% of Android's lag. In a word, entropy (or lack thereof).
Google's JVM, like Sun's, reads from /dev/random. For all random data. Yes, the /dev/random that uses a very limited entropy pool.
Random data is used for all kinds of stuff.. UUID generation, session keys, SSL.. when we run out of entropy, the process blocks. That manifests itself as lag. The process cannot continue until the kernel generates more high quality random data.
So, I cross-compiled rngd, and used it to feed /dev/urandom into /dev/random at 1 second intervals.
Result? I have never used an Android device this fast.
It is literally five times faster in many cases. Chrome, maps, and other heavy applications load in about 1/2 a second, and map tiles populate as fast as I can scroll. Task switching is instantaneous. You know how sometimes when you hit the home button, it takes 5-10 seconds for the home screen to repopulate? Yeah. Blocking on read of /dev/random. Problem solved. But don't take my word for it .. give it a shot!
Update!
I've built a very simple Android app that bundles the binary, and starts/stops the service (on boot if selected). I'll be adding more instrumentation, but for now, give it a shot! This APK does not modify /system in any way, so should be perfectly safe.
This is my first userspace Android app, so bear with me!
Note that this APK is actually compatible with all Android versions, and all (armel) devices. It's not at all specific to the Captivate Glide.
Caveats
There is a (theoretical) security risk, in that seeding /dev/random with /dev/urandom decreases the quality of the random data. In practice, the odds of this being cryptographically exploited are far lower than the odds of someone attacking the OS itself (a much simpler challenge).
This may adversely affect battery life, since it wakes every second. It does not hold a wakelock, so it shouldn't have a big impact, but let me know if you think it's causing problems. I can add a blocking read to the code so that it only executes while the screen is on. On the other hand, many of us attribute lag to lacking CPU power. Since this hack eliminates almost all lag, there is less of a need to overclock, potentially reducing battery consumption.
If you try it, let me know how it goes.
ROM builders - feel free to integrate this into your ROMs (either the .apk / application, or just the rngd binary called from init.d)!
If anyone's interested, I've launched a paid app on the Play store for non-xda users. As I add features I'll post the new versions here as a thanks to you guys (and xda community at large for being such a great resource). But if anyone's interested in the market's auto-update feature, just thought I'd mention it.
Cheers!

Should this help with the lag that we get on the Play?
If anyone else wants to try it heres the link to the thread:
http://forum.xda-developers.com/showthread.php?t=1987032
I tried it and it i got faster loading on some minor stuff (like contact picture loading) and apps installed on the internal memory seems to load faster, in terms of UI smoothness I don't notice any difference, because UI is smooth since the beginning
I think i may try it out although i don't see any instructions

BTW, somebody already posted this in the XPlay Android Dev section:
http://forum.xda-developers.com/showthread.php?t=2073382
I know, many people here want to have Android 4.x.x on their phones, but unfortunately, because of low-end processor as well as less RAM, these CM10/CM10.1 ROMs are laggy and slow. I am also one of them, but, after using these type of roms since 4 months, I have now got a perfect idea of using them. So, I am sharing the way I use these roms. Many people told that this also helps for CM7 users. So, now I have declared this thread as UNIVERSAL PERFORMANCE THREAD. This method can be used on - Stock | CM7/9/10/10.1.
NOTE : This thread is mainly from galaxy mini forums. But, I have posted it here also, so that Gio users also get its benefits.
NOTE : This method is same for PAC ROMS.. because they are based on CM. So, you can use this on PAC ROMs also.
♦ FINDING STABLE VERSION :
First of all, you will need to find a good stable version of any CM7\CM9\CM10\CM10.1 ROM. Find stable version by asking in general discussion thread of those particular ROM and then download that version. But, do not flash now.. Follow next step.
Note : For CM7 users - Official CM7 is best, but if you want you can try it on custom roms also. If you are using CM7 custom or stock based custom rom, then for scripts n tweaks to work, you must delete all the scripts from init.d so that scripts will not get overridden.
♦ SLIMMING THE ROM :
Slimming means making rom size less by removing unwanted and unnecessary applications from system/app. It reduces system memory use. Here is a chart of cm10.1 apps which are safe to remove - LINK
With reference to that chart you should remove following apps with adding alternatives to them.
Note: Left side apps are to be removed and right side apps are alternatives.
● LatinIME.apk - WP7 Keyboard App
● Browser.apk - Holo Web Browser
● CMFileManager.apk - Root Explorer File Manager
● Trebuchet.apk - Holo Launcher
NOTE: On CM7, default ADW is good, but you can also use Holo Launcher.
Other apps that can be removed without alternatives-
● CalendarProvider.apk - One of the big RAM consuming apps. This app start anytime, you do anything, so it will be a big save of memory removing this app. But, you will get problems with calendar sync..
● GoogleCalendarSyncAdapter.apk - Reomove this only if you do not sync calendar.
● Email.apk - If not in use.
● Gmail.apk - If not in use.
● Talk.apk - If not in use.
● GoogleBackupTransport.apk - It is used in google backups, remove on your own risk. (Not a risk, i always remove it.)
● ChromeBookmarkSyncAdapter - No use.
● HTMLViewer.apk - Never needed.
● UserDictionaryProvider.apk - It is useless without LatinIME.apk.
● VisualizationWallpapers.apk - Wallpapers app. Remove it always.
● CMWallpapers - Remove it always.
● VoiceDialer.apk - Do you really use it?
● LiveWallpapers.apk - Dont you care for your battery?
● QuickSearchBox.apk - If you dont use.
● PicoTTS.apk - Text to speech function.
NOTE: Alternative apps should always be installed in system/app only. For that, I recommend you to remove these apps drectly from rom's zip before flashing.
♦ USE OF SCRIPTS N TWEAKS :
Many people use hard scripts n many tweaks to get good performance. But, it is totally wrong.
Highly recommended to use Activo Speeder. It is the best script for performance. Dont use anyother thing with it- such as ram manager, seeder or anyother script.
(Note: If the above script doesnt work on your device then please find another good script and flash it.)
IT IS RECOMMENDED TO USE SUPERCHARGER ON ICS\JB :
After testing a lot, I found that SuperCharger is the best script which can be used with any ROM to get more performance and for perfect RAM Management. Here are some steps on how to use SuperCharger -
● Here is the original thread for SuperCharger script.
● Script can be downloaded from this download page.
● Download latest script as well as starter package if needed (Read Original Thread).
● Now, for 4.x.x ROMs, you do not need to do anything with services.jar. But, for below 4.x.x, services.jar needs to be patched to get SuperCharger Memory Management working.
● Now, copy script to SDcard and run it with Script Manager as root. For more detailed guide plz prefer the original supercharger thread.
● Now, you are running the script. You will find many options and info on screen. Read it all and choose what you want.
NEW DISCOVERY : SUPERCHARGER + CROSSBREEDER = ULTIMATE PERFORMANCE WITH MAX ENTROPY ! - by Dark Passenger
● LINK FOR THE POST.
Here are some tweaks-
In Build.prop -
●
Code:
ro.ril.disable.power.collapse=0
and change the value from 0 to 1. (Add the line with proper value if does not exist)
This one is for battery saving.
●
Code:
dalvik.vm.heapgrowthlimit=48m
If it already exists then just match the values.
This is a VM Heap management for RAM.
●
Code:
ro.ext4fs = 1
Improves EXT4 performance.
● IMP :
Add following lines below "# Other" in build.prop
Code:
ro.com.google.locationfeatures=0
ro.com.google.networklocation=0
(If exists, just change the values as above).
(Note: This one will remove location feature increasing performance freeing up more RAM. This frees up to 30mb of RAM)
And now remove NetworkLocation.apk from system/app as well as com.android.location.provider.jar from /system/framework.
For further build.prop tweaking, you can use this great guide -> Click Here. Thanks to Dark Passenger for some build.prop tweaks.
This much tweaking and scripting is enough. DONT USE TOO MUCH TWEAKS N SCRIPTS.
♦ BASIC APPS TO USE :
Your rom's performance also depends on the apps which you use. Always look for apps' memory usage and if the app consumes more ram then try to find an alternative app for it. Here are some basic apps which you should use (i always use them).
● Use Root Explorer as file manager, Holo Launcher as Launcher.
● Use Cache Cleaner App. It is must. Clean cache once a day.
● Use Root Cleaner App. A must have app. Do "Quick Cleaning" twice a day. It will regulate your performance.
You can also freeze the apps you are not using at that time, such as DSPManager (Unfreeze it only at the time of listening songs)
Freezing Google Apps will be a great way to reduce RAM consumption.
● Use this amazing app - Autostarts. This app controls the apps that start automatically in your phone. If you want settings which I use then PM me. I will tell you, how to use this app.
CLICK HERE FOR AUTOSTART APP SETTINGS
● ABOUT TASK KILLERS :
Using task killer is good but, it is also bad. Task killing is actually meaningless. Some apps never really get killed. They start again n again. So, use Autostarts instead task killers. But, here is a nice app for killing processes and freeing RAM. This is the original app. I have themed it to look good. Download it here.
Use it as a task killer, press menu button and include system processes and then start killing processes which are useless.
● Try to use apps as system apps.
● If you are using UC Browser then in its settings, check "Clear Data on Exit". If did, you will see UC will take less than 10mb but, if you wont do this, UC will take more than 15mb.
♦ IMPORTANT TIPS AND SETTINGS :
● Always flash rom with a clean wipe and proper flashing method.
● Do not flash gapps again if they are included in the rom.
● Do not flash internal memory scripts as they reduce performance.
● Use Adrenaline Boost. Boost once or twice a day. Boosting much will increase battery consumption.
● Use Root Cleaner app and freeze the apps which you are not using at that time. Freeze Google Play Store, Google Services Framework and other google apps which are always on. Unfreeze them when you want.
● The apps used for Backup purposes should not be installed always. Keep them in your sdcard and install them when you want and uninstall when done with them.
● Basic apps should always be in system/app.
● In Developer Options -
Set all animations scale to .5x
Set Background Process Limit to "Atmost 4 processes", if issues occur then set it back to "Standard Limit".
Enable "Kill App Back Button". Always use this feature to come out of the apps which do not really exit on pressing just back button.
● Do not expect much from our phone as it is not a high-end phone. Dont expect good battery life but, still to gain good battery life. Keep RAM free by using the ProcessKiller app as told above. I always get 170 mb RAM free.
● Do not charge battery until it gets discharged upto 10% or less. While charging do not remove it till it reaches 100% and 20 mins above that.
● Calibrate battery when needed.
● Avoid use of apps which are always running either in background or foreground.
● Press thanks. .
Thanks! I'm definetely going to try this out, even though I'm not running JB but ICS.
Deleting unneeded apps works on every Android version I think, and ActivoSpeeder works on ICS too, so I'm happy!

this made everything a lot more laggy and gmail stopped syncing... Also takes about 3 times as long to boot.
No offence, but this is pretty terrible. And after doing some actual research a lot of the "tweaks" you talk about here are never proven effective and frowned upon by actual experts. Even in the article you linked the writer says that something like dalvik heapsize is not something you should or have to change.
I would advice anyone to NOT waste any time on this.
ps: the last part (under tips and settings) is actually some good advice, although the background process limit is not saved in CM10 (and the max.mem tweak doesnt work), so you'll need to do that everytime at startup

please dude if you don't know how to tweak you can go i don't use this guide but it's a good one maybe you installed all those thing over a already tweaked rom, this guide if for clean stock, cm7/9/10/10.1
Nice guide...but I think you are wrong about the services.jar. You have to patch it when you use ICS or Jelly Bean, not on GB. And there is no Official CM7 on Gio.

I applied it on a clean cm10.1 twice, had the same results, twice. I am not trying to talk down on someone elses work, but the fact is that some of the "tweaks" he talks about are never proven and often based on urban myths and the perception of people who applied them and saw improvement (placebo effect). fwiw, OP himself links to an article that busts some of the myths about tweaks, he tells people to apply...
So, maybe my device didnt start to lag more, in fact, it might have been more stable... however, setting the fs.file-max too big (as is one of the many things that activo script does) will make it less responsive, like there is a 100ms sleep between every action... I also experienced that with manual sysctl.
And some other tweaks that do work are still not great for everyone because they got other side effects that are not mentioned anywhere in this article. I got no idea why sync started giving errors and gmail stopped updating (twice) after these tweaks, but they did....
I am completely new to android, and should've done more research before blindly following some article that states to have some magical cure. But I am not new to linux and it seems this community suffers from the same kind of idiosyncrasies at the bottom end, where people constantly try to fix **** that isnt actually broken.
I'm talking about tweaks here obv, removing gapps. bloatware and lowering requirements for the OS is obv fine...
When someone's Gio lags, it's probably because they want to do stuff with it it's not made for, it's a slow device with minimal specs that does the pure core tasks as pda, phone, messenger and email, and as long as you do those it'll be fine. If you want more, buy a better phone. If it's that important to you and you dont have money, learn to appreciate what is actually important in life.

Look in signature, this thread is also there for Fit as well as Mini and is getting good response all over.. but you are the first one to complain on this. My advice to you- DO NOT USE THIS DO NOT POST HERE!
Some of your sayings are correct but, still this is the best way to increase performance. You might have did something wrong because this has been researched by me and some other people that this guide is perfect for low activity devices like ace, fit, mini, but if you dont want to use then dont use. I have NO PROBLEM.(I really dont get money or anything for this). lol..

okay go step by step and tell me what is it that is actually bothering you about the tweaking.(talk only about supercharger method not activ speedo).
yes most of the tweaks are utter bull**** The tweaks in the op(build prop ones are actually proven read the article again).As for dalvik size its recommended to keep a size around 48 so that you processes don't need to split their dalvik heaps into two separate piles thus reducing ram consumption.

This is one property that has cropped up recently in various build.prop recommendations for ICS. Typical suggested values range from “48m” all the way up to “256m”, likely motivated by the common misconception that more is better. The real purpose of this property is much less obvious than one might initially guess. It is also another one you should probably avoid changing.

Should you change this setting? Probably not.

Maybe you are right, I dont know all the technical implications, and I got no way to check it other than to test it and I see no difference in ram consumption if I change this property.
The ro.power.dissable thing might shut off wifi when in deep sleep and jumps back to mobile (I think, it happened after applying all tweaks and it seems the most likely thing to do that), but whatever causes that, you should warn people about that sort of thing as it can cost them money..
I didnt use it for long and I'm not an expert, i'm just sharing my findings, people can make up their own mind about it and share their experiences as well..

the ro.power.disable.ril actually causes the phones radio to go to sleep so if your mobile data is off there is no reason to switch on rather the wifi might switch off(devs already stated so) and again switch back on once you get out of deep sleep.
its a good thing that you are coming back to provide a feedback and is appreciated(at least should be).
the change for dalvik.vm larger than 48 only allows the heap to grow to that value then split into a new heap since we can't/shouldn't/don't use apps with such a large memory footprint the chances of a split occurring post 48mb(gb and below) and 64mb(ics and above) is highly unlikely hence the changing the value to a larger quantity will make no difference.
PS personally even i dont like activo mainly cause i dont know how it works rather i use supercharger and its a much better option in my opinion.

No, I already told you that many of your ideas are correct but, your way of expressing was not good.
Ex- You said that "Dont waste time on using this guide".
Now, if you think that was correct then please do not post again. If you are providing information then you can but, if you are telling people not to use this then dont post.
In fit's thread, Dark Passenger also wanted to express his ideas and wanted to help me. And I was happy about that. Because the way he helped me was like he really wanted to help. But, you was not polite as him.
You can ask Dark Passenger, there is a lot of information in the thread provided by him and I used that. And he never complained like you.
@Dark Passenger, please explain him.

When you use ics or jelly bean you need supercharger script and a patched services.jar (it's easy to do) because any other script don't works 100 % on it.

HI ALL,
I will root my device , but I want to know how to increase its performance and speed and reduce RAM usage?
and what is the best browser for Android for fast browsing and low memory usage?
Most of the speed increasing and RAM decreasing can be done without root. Replacing Touchwiz with Apex or Nova Launcher is the first step that makes the most difference. Disable most of the bloatware and turn down animations in developer options.
This post probably belongs in the Q&A section, not the software one.
Reduction in RAM usage doesn't necessarily equate to performance boost. Android memory management does a good job of keeping things running smoothly so the goal of debloating should not be to free up RAM. To maximize performance with regards to memory usage with Android what you'll want to do is debloat your device to the point that applications that you'll never use are no longer loading into memory automatically (either as active applications or cached) which will allow other frequently used applications a chance to load into RAM/cache for quick response times. Running memory management software is also counter productive as it will battle against Android's own memory management and kill background applications that you may want cached for quicker response when needed.
Personally I WANT RAM to fill up because if I'm jumping from application to application I don't want to wait for things to load from storage into RAM. I also refrain from cache cleaning frequently because I have a particular routine when I use my device (frequenting particular websites and using particular applications daily) so clearing cache frequently will only force my device to have to re-cache things unnecessarily.
Getting down to the nitty gritty of how to debloat, the approach I took for my device is to work with a few applications; SystemPanelLite Task Manager, Greenify, Boot Manager and Titanium Backup. I would clean boot my device and let it sit for a while (several minutes) to cache applications as it saw fit. I'd then pop into the system panel lite application and look at what was loaded into both active processes and cached. I'd evaluate each entry to determine for myself whether or not I wanted that application to load automatically or not OR NEVER. If the answer was never then I'd use Titanium Backup to freeze the application (of course for each app I'd do my research to see if it was serving an important function). If the answer was that I needed the application but not all of the time then I'd look into Greenifying it and also considered disabling it from starting at boot using boot manager.
I'd do the above iteratively until all I saw in RAM or cached were applications and services that I felt were important. Never during this process did I care how low memory usage was since the goal is to preload as much of the important stuff as possible.
In the end I ended up freezing a ton of Samsung apps, especially after uninstalling applications that relied on their own app store like Hancom.
Of course a quicker way to reduce bloat is to go to a ROM that someone else has debloated and start there as a base. I began my own debloating process early last year though so starting again on a ROM even if it already is debloated to a certain extent doesn't seem worth it for me at this time (but if a lollipop update rolls out and a ROM developer updates to that then I'll surely try it).

This post probably belongs in the Q&A section, not the software one.
Reduction in RAM usage doesn't necessarily equate to performance boost. Android memory management does a good job of keeping things running smoothly so the goal of debloating should not be to free up RAM. To maximize performance with regards to memory usage with Android what you'll want to do is debloat your device to the point that applications that you'll never use are no longer loading into memory automatically (either as active applications or cached) which will allow other frequently used applications a chance to load into RAM/cache for quick response times. Running memory management software is also counter productive as it will battle against Android's own memory management and kill background applications that you may want cached for quicker response when needed.
Personally I WANT RAM to fill up because if I'm jumping from application to application I don't want to wait for things to load from storage into RAM. I also refrain from cache cleaning frequently because I have a particular routine when I use my device (frequenting particular websites and using particular applications daily) so clearing cache frequently will only force my device to have to re-cache things unnecessarily.
Getting down to the nitty gritty of how to debloat, the approach I took for my device is to work with a few applications; SystemPanelLite Task Manager, Greenify, Boot Manager and Titanium Backup. I would clean boot my device and let it sit for a while (several minutes) to cache applications as it saw fit. I'd then pop into the system panel lite application and look at what was loaded into both active processes and cached. I'd evaluate each entry to determine for myself whether or not I wanted that application to load automatically or not OR NEVER. If the answer was never then I'd use Titanium Backup to freeze the application (of course for each app I'd do my research to see if it was serving an important function). If the answer was that I needed the application but not all of the time then I'd look into Greenifying it and also considered disabling it from starting at boot using boot manager.
I'd do the above iteratively until all I saw in RAM or cached were applications and services that I felt were important. Never during this process did I care how low memory usage was since the goal is to preload as much of the important stuff as possible.
In the end I ended up freezing a ton of Samsung apps, especially after uninstalling applications that relied on their own app store like Hancom.
Of course a quicker way to reduce bloat is to go to a ROM that someone else has debloated and start there as a base. I began my own debloating process early last year though so starting again on a ROM even if it already is debloated to a certain extent doesn't seem worth it for me at this time (but if a lollipop update rolls out and a ROM developer updates to that then I'll surely try it).

Really helpfull man thanks a lot for all the information u shared, am ok with but guess will need to do more research for greenify cuz I didnt use it at all, secondly what office u used after uniinstalling hancom?
I'm currently using Microsoft's Word/Excel Preview apps and have an Office 365 account to enable editing. I've just started (1 month trial) so I haven't really gotten a lot of use out of the software yet.
I can't speak for anyone else but myself but my reason for dropping Hancom was twofold; 1) it did not support the review/commenting features that I needed in Word files and 2) it often required updates at inopportune times. My needs are quite specific, my tablet is a reference and note taking device for meetings and is never used for production type work. As such, I need the ability to take email attachments, open them for review and comment and then send the comments back out as email attachments. The limitations of Hancom when it comes to track changes were a deal breaker for me since I could not see the history of development of reports/documents.
Microsoft's mobile version of Word implements the best support of track changes/comments that I've found to date, so I'm forced to pay the premium of a 365 subscription on this device to get what I need.

thanks for reply and sorry for late , hoping the android 5 be great
Install cm12 lollipop ROM. Drastic improvement in browser performance and gaming. For example, Asphalt 8 is extremely slow on stock, even overclocked. On cm12 it runs perfectly with max graphics settings. Unfortunately you lose all the cool touchwiz features like multi window. For me, the performance improvement is enough that it's worth the lost features. I'm anxiously waiting for the official lollipop update.

performance apps and tricks that will speed up your Android
1.Android assistantAndroid AssistantWith downloads in the 10 to 50 million ballpark,Android Assistant(AA) has managed to score an impressive 4.6 stars! If anything, the non-flashy, conservative interface should be nothing less than an indication that this is a timeless collection of tools that just works. Keeping track of what's important, the first tab features the coveted Quick Boost button. Alike many other similar applications, AA will flush all the unneeded processes and services down the drain, leaving more juice for you to play with. Under the Process tab, you'll get more of an in-depth view of what's running on your system -- killing those is within the tools AA offers, but this is only a temporary solution (more on this later). The other, more important tool, is the System Cleaner, which allows you to free up space by wiping the cache of apps, the web and other. Keep in mind that you're better off keeping the cache of apps that you use daily -- wiping it will actually slow down their launch time in consequence..

Some battery life stats is what I'm most interested in. This thing discharges by just looking at it.
Still early, some wifi wakelocks but look promising. The guru of GSI, Phh has an S22 on the way so expect the GSI's to be more or less flawless in the future

Thank you so much. Can you please share your run.sh script too? I will be very thankfull. Did you use 7zip in order to compress the recovery image in to .lz4? I am using ubuntu.
Can someone please tell me how to manually add or include fastbootd in a stock recovery.img? I can't get this script to run properly. Thanks in advance.
Hi can anyone give detailed instructions how to enable fastboot on stock recovery ?
Late reply: join phh group on telegram and request an recovery with fastboot enabled. There are memebers that will help you.

When I get home tommorow night, I'll link you a few places to read and help you do some cleaning up because these Samsung phones are full of junk and services that the phone can live without. I've been going nuts trying to make this rubbish of a device perform better and I managed to get it to waste less battery while active and inactive by disabling and uninstalling A LOT of stuff I don't need and so on. And I came to the conclusion that for daily usage I didn't need 100% of the 8 Gen 1 chipset. I therefore cut in half the frequency for the 3rd cluster and decreased the ones of the other 2 as well. I basically limited the max freq of the CPU without noticeable effects on the performance. Probably benchmarks would should how much performance I wasted, but as I don't care about numbers on paper, I'm pretty ok with how the phone's running right now after cleaning it up. The battery is very small, the CPUs are very inneficient, both SD and Exynos, despite the marketing claims, the apps are very power hungry and the CPU gives the processing power in an aggressive and inneficient when the transition from a frequency to another should be smoother and not as quick to give it all up when it's actually not necessary. Paired with all the useless processes and services which work like lunatics to do whatever BS they're trying to do, whether it is while you're using the phone or in the background, and you're left with a terrible user experience that makes you contemplate throwing the phone away.
I used an iPhone 13 Pro for 4 months before buying this thing and I forgot to look at the battery level because iOS is that efficient. It was terrible for me overall but when it comes to smoothness and battery life, there's nothing in the Android world that comes even close to that. The best Android device that comes close to Apple's latest amd greatest is probably around 5,6 years behind. That's sad but it is what it is.

I swear all the **** Samsung installs on their devices is turning me crazy
No Samsung, I don't want Bixby, I don't want this side taskbar installed by default, I don't want your cloud services by default, no I don't want your "secure folder" thing, I don't want your Samsung Pass thing either
Like come on, the above list is like 25% of all the **** they install
Visually OneUI is awesome and I love it, I love some of the features and options that they provide / provided very early, even before Android sometimes, it's highly customizable and things like Goodlock are awesome, but it would be even better if you could allow us to remove ALL of their apps without having to use ADB or some weird stuff like this
I think Digital Wellbeing is a good example of what should be removable as I don't see everyone using it and it's even more of a shame when you realize that uninstalling it with ADB works perfectly fine and causes no issues...
Something that I love on Windows in the "services" tab where you can see each service, what it does, weither it is ok to disable it or not, what features you lose if you disable it... I think Android should do the same or something similar with system apps

Exactly. They like to push down your throat their crap. All the stuff you mentioned I already disabled or uninstalled altogether. Digital Wellbeings was draining my battery in the background at all times without even having it configured. So that was deleted. Bixby is gone too and a bunch of other things. But the main issue for all this is the small battery for the terrible quality 8 Gen 1 or the Exynos 2200. 4nm is pure marketing at this point.
Sorry, @NisseGurra for not getting back here last night, like I said I would.
I also realized afterwards that you were on a GSI build but I intended to help you clean up the stock firmware.
The best advice I can give you right now though is to try doing what I did. Please don't take it personally if I explain or define stuff that you might already know or actually know even better than me. If someone else reads this, they might learn something from it or do some tweaking even if they're on the stock ROM or something custom. You take only what you need from this.
The whole thing starts with the process of opening the Apps section in the Settings, checking/turning on the "system apps" option and opening everything in there one by one. You'll have both apps and services showing up in there and what you wanna look for is the "Battery" section, or whatever it's named on your GSI. You basically need to see how much battery it's wasted since the last charge. High battery usage=no bueno. In that case, you google that app/service, weird name or not and see if it's rudimentary for the proper functioning of your phone. If it's not essential or it's used as a service for some apps that you don't even use but it's there just in case, then you can get rid of it. And obviously, you have to do this for every single app and service in there. It's a pretty time-consuming job but if you want to keep your sanity in the end, then it's a good activity. After that, for the remaining things, you can use "Servicely" from the Play Store and force the stuff you don't need at all times to sleep/Standby when the screen is off or even prevent it from running in the background altogether.
You should also download Naptime and use it to activate Aggressive Doze and disable Motion Detection too so the phone stays in doze mode even when you're moving around, a scenario in which by default the phone comes out of doze whenever it detects motion.
Stuff like "Find my phone" I had to turn off. There was one option for this thing somewhere in the google account section and also in the Samsung provided services in the Settings, on the stock firmware. Talk about a huge mess. I don't really need those. If I lose my phone, which never happened to me so far, it is what it is, but I'd rather have better battery life than have a service running at all times just for the moment I lose this crap if that ever happens.
This whole thing above is mainly meant to improve the standby time when the phone is idling.
And to not forget to mention this, I have Battery Saver active at all times. Normally, everything should be crippled while this thing is on including the refresh rate of the screen which gets stuck at 60Hz. For that, there's Galaxy Max Hz. It offers the ability to activate something called "Keep smoothness on power saving mode" and you won't even know that the thing Is even on. The essential part is that the OS is supposed to be less active, decrease the background BS and also the power of the CPU down to 75%. This part doesn't really matter because I already planned on downclocking it but if there's anything applied by default to make the CPU less aggressive along with the stock decrease to 75%, then downclocking it would make it even better because now you have lower frequencies which now jump up and down at a slower rate. I mean I hope it's done like that. I haven't monitored the difference in the activity of the CPU with Power Saver on/off so I can't tell for sure. It would be logical to happen that way though. Another important little part is that I installed "Universal GMS Doze" which allowed me to put the Google Play Services on "Restricted" in the Battery section. I had to restrict the "play services framework" too cause they liked to molest my battery too when I wasn't looking. But I digress.
On the stock firmware, I also use Battery Tracker made by Samsung. I really like it because I can easily select the period of time of activity/battery drain by dragging 2 sliders from one side to another and see what happened during that time, and you get background activity stats and what percentage of the battery it's wasted.
For the much better and more detailed Screen on/Screen off stats or charge/discharge information which all show in a useful notification, I use Battery Guru. It barely drains any battery so it's very well optimized.
Back to the technical part, the other important thing was to downclock the CPU, and this is essential for the active time which later translates into better SOT.
I'm using Smart-Pack Kernel Manager for the tweaks because it's the most detailed of them all and well rounded in my opinion and it's also the lightest on the battery, while in use, of course. It's got a side panel with all the sections that have the tweaks I'll mention in this post.
The following part is gonna be a bit more detailed. It's just a few tweaks in the end but I'll throw in some basic information here and there to make it a little more informative and nice to read. Keep in mind that even if I tweaked the stock firmware here, the tweaks are essentially the same for the kernel or at least similar. The values and options shown in the kernel manager can differ in terms of naming or the way you can change them, but they should be overall similar.
Note that this is more like a presentation of what I did on my phone, not a tutorial. You can open that kernel manager, look around and see for yourself the range of tweaks that are available of which a few are the ones I changed.
Now to business.
The stock max frequencies for the 8 Gen 1 on my S22 are something like this:
- 1785MHz for the 4 LITTLE Cores, 2496 for the 3 Middle cores, and 2995 for Core 8, which is also the big core (terribly inefficient "fat" bastard).
So we've got: 1785, 2496 and 2995 respectively.
My phone is running smoothly with all these downclocked right above the border between noticing and not noticing a difference in the UX department if you get what I'm saying.
So my current maximum clocks for all 3 clusters are 1363, 1555 and 1401 respectively. They're lowered pretty drastically, I know, but I don't care about benchmarks, in which you'd probably see a difference. In the real world, opening and closing apps among other regular things, are not gonna be noticeable. It's not like you're gonna sit with 2 phones next to you, a stopwatch in your hand and cheer when your phone is half a second faster than mine. It's just not gonna happen. That 30% increase and performance. blah blah, when a new generation of a CPU is announced you're not gonna notice especially when we're talking about CPUs that are only 1 generation apart.
Anyway, these lower frequencies will obviously help with thermals mainly but also with the battery life, although the difference for the latter is not that huge it's still better than before.
The CPU Governor for all 3 clusters is set "walt" by default. I couldn't find any information on how it's supposed to work and behave but because it's the default, I'm sure it's focused on something in between performance and battery savings. So I set it to "conservative" for all 3 clusters. This governor likes to get the frequencies back down as soon as possible after a task is done. So this is also gonna help with thermals.
Now to the CPU Hotplug. In the past when big.Little became mainstream, a whole performance cluster was called in for the heavy tasks and they followed a basic routine: when a certain threshold is crossed, the big cores take charge of the situation and when they cross a second threshold, which is a lower value, those big cores step away and they hand over the steering wheel back to the Little cores for the light tasks until they're needed again. They still pitched in but a bit more lightly. Now just one big core appears to be able to do that on its own, however, this time the job is split between the big core and the middle ones. So there's a bit more control over a situation because you've got those middle cores that are pitching in for the medium intensive tasks.
Anyway, I decided to up that threshold and basically make the CPU ask for the big core's help when the job gets a bit more difficult, heavier, essentially making it contribute less often. I don't want to reboot my phone to see what the default values were but now they're basically higher: "Busy down Threshold = 50", and "Busy up=70". I just explained what this threshold is, so you probably already got how this is supposed to work looking at these numbers.
And the last thing tweaked is the GPU. Sadly, the stock kernel doesn't allow for the downclock to stick. It's missing the parts which allow for this sort of functionality because it's stock and wasn't meant to be tweaked. The only thing I could do was to change the power level. You haven't got anything in there other than an option to let you change a value. The essence of it though is that the lower the number, the better the GPU performs. It's not gonna work outside of the defined parameters though. It only gets more active. Anyway, the default value is 10. I set mine to 12, which is the last level. This way I basically put the GPU in a more "conservative" state, so to speak. While gaming, I haven't noticed any performance loss, so hooray. It is doing its job but it's a bit less aggressive.
To finish this long a$$ post, I gotta say that after doing all this above, my battery life has improved quite drastically.
3, 3.5h SOT was what I consistently got without tweaking anything. Right now I'm at 4h49m SOT for only 64% wasted. I charged the phone only to 85% and the battery is down to 15%. The idle drain is only 0.3%/h.
I'll post a screenshot for the hell of it. Anyway, so far so good. One thing's for sure though. I'll do some research and if I manage to find any battery from another Samsung phone that's bigger but is very close in size to the one in this phone, it doesn't matter if I have to cut some of the lips inside to make it fit, I'll do it. I'll make that a project.
Edit: Everything I mentioned above is getting balanced out by other things somehow and 3.5h is the definitive SOT on average I have been getting since forever now. I therefore stopped trying anything, relocked the bootloader and I haven't done anything to the OS anymore. The SOT stayed the same and there aren't any improvements with any update. So this is pretty much how it is and there's nothing we can do about it. The phone is simply pure trash regarding the battery life.

Sorry, @NisseGurra for not getting back here last night, like I said I would.
I also realized afterwards that you were on a GSI build but I intended to help you clean up the stock firmware.
The best advice I can give you right now though is to try doing what I did. Please don't take it personally if I explain or define stuff that you might already know or actually know even better than me. If someone else reads this, they might learn something from it or do some tweaking even if they're on the stock ROM or something custom. You take only what you need from this.

Thanks, an excellent post on how to get rid of battery leaks.
Its a pity that this work is needed 2022, should be optimized system from Samsung from start.
The problem now is the wifi bug, very strange that Samsung not noticed this in their testing.
How good does the GSI work on this device? Can you use it as daily driver? I am thinking of buying this phone, but don't want to use One UI.

Some battery life stats is what I'm most interested in. This thing discharges by just looking at it.
