Explain this outcome of Advanced Task Killer

I've a buddy of mine that found ATK on his own, installed it, and says he sees a "noticeable" improvement in speed on his Captivate (And he's got the lag fix already). I tried to reason that it's placebo but he does swear, it was a large improvement in speed. I can look online and find other reports of this.
And before you go down that route, he had nothing much more than stock installed (Facebook, etc... Nothing that I don't have).
I've also seen someone go from 8 hours of battery life to 12 hours just by installing ATK.
Explain these.
If Android TRULY managed memory so well, how does someone gain such performance boost from killing the processes?
If ATK was actually detrimental to battery life, why does someone gain more by using it?
I've seen both sides. I haven't noticed any speed differences running ATK compared to not running it.
I have also seen another side that says ATK hurt their battery life.
Seems there's too much conflicting info out there. You can argue til you're blue in the face that "it is negative"... But you cannot deny results some people are saying. So I'm just asking those of you that argue from that perspective... To explain these situations?

A quick question, does your buddy kill the processes and then let the phone sit? Sure this is going to increase the battery life but so does pulling it from the phone all together.
Bottom line is there is no definitive answer as to the merits of ATK. If you like it, use it.

Most results tend to be anecdotal in nature. Those that get better battery life out of using ATK probably don't realize it's due to ATK killing off bad apps, and not due to freed-up RAM. If Android needs more RAM, it will shut down programs by itself. That 3MB of RAM you freed up with ATK isn't nearly as useful as the fact that same app you just killed was also hogging your CPU. Cause/effect, correlation/causation, etc.

People also get what's ive heard as the "new phone syndrome" where the phone is used constantly the first couple days, and the battery life is then thought to be horrible.
Also tell your buddy to look up settings > about phone> battery usage as the battery is largely affected by voice calls and the screen. A 5 min call uses more than you think.(thus the reasoning behind why I don't use atk)
Sent from my SAMSUNG-SGH-I897 using XDA App

To a large extent battery life, phone, and app performance will always be somewhat subjective. No two people are going to use their phones in the exact same manner. depending on how a person uses their phone and what they have installed on their phone ATK may very well improve their phone's performance - especially if they have a bad acting app on their phone.
As for my personal testing, my phone does better without ATK. However I was a little biased against ATK from the beginning and this could have affected my results. I have used a half dozen different linux distros over the past eight years and while I have many times had to kill or force close an application, I have never needed to manually manage memory. Linux generally does a good job at managing memory and multitasking.

I can't say for your friend, but I was using a task killer for the first month I had the phone, and now I do not. So far performance, and battery life are the same with and without. I finally removed my old task killer and installed watchdog all I have it set to do now is simply alert me if an app is using excessive cpu, which would likely be due to poor app quality anyway. Other than that I've had no issues.

I guess this is true. I've never seen claims that Android manages CPU, etc effectively, I've just seen claims about the RAM usage.

That's what I've done as well, and yea... Can't tell a difference with and without (of course I also go "back" out of apps when I'm done).

i dont think it works that well

Lag

I know i made some negative posts on the htc u11 but tbh i love this phone and i was just feeling annoyed by some things.. But i wanted to ask, i expected this phone to be lag free and super fast, yes it is super fast abd smooth but the thing is that it does lag with me and it is noticable. Happens a couple of times a day i think, am i the only one having lag problems? I do have the power saving option on and idk if it's what's causing the phone to lag or not but all i know is it does lag with me and it is unexpected since this phone has htc sense and snapdragon 835. Share your thoughts below

Not just lag but freeze

I'll share my thoughts : you should really stop openning these threads because actually no one believes you, we're all aware that you're here to throw up on this phone.
For who ? We don't know.
Maybe a simple Samsung fanboy who's upset because HTC made a better phone than Samsung's flagships two years in a row ?
Now stop please, it's not funny and it will not prevent people to buy the U11 if they want to.

I don't see Samsung logo on front... Soo no lag here.

Turn off the power saver. It's not needed with the Snapdragon 835 and it alters the distribution of the load between the clusters. Things that would complete swiftly and thus conserve power on the big cores gets offloaded to the little cores. The kernel isn't optimized to take advantage of the efficiency of the 835. With it being incredibly easy to get 7 hours of SoT, there is no need for the power saver. Somewhere on XDA there's a very detailed explanation as to what the power saver does and why it shouldn't be used unless your phone is about to die but it curbs both clock speeds and shuffles around the load, preferring to not use the big cores at all. It basically abolishes the efficiency of the big.LITTLE premise and often has opposite the intended effect if you're actively using the phone.
If you need optimization, you can use Boost+ to set individual high drain apps up to be run in 1080p, limit background usage, etc. This is much more effective than essentially killing the performance of the phone and gaining little, if any, additional battery life. It can have the opposite effect and in fact did so on the 10.
Think of it like this - the little cluster may take half the power per cycle than the big cluster (I don't know the exact numbers and highly doubt it's anywhere near half but it works for the example). You open an app that would have completed in a single cycle on the big cluster. That same app can take four to five cycles on the little cluster. You've just thrown efficiency out the window.
If you have a lot of background apps misbehaving and a lot of apps constantly syncing, it can be advantageous but I haven't seen any evidence of that since the Snapdragon 820. The 805 in my Nexus 6 benefited from it but my Note 5 with the Exynos 7420 and my 10 with the Snapdragon 820 suffered.

Lag?? OP must be in the wrong forum. Please go back to your Lagsung S8..

I had freezes on my previous HTC(one m7), and the reason was some crappy game I installed. After removal - no lag at all. Just try and revise your applications and remove ones you have doubts

0 lag. None, Nada, zilch. Either the person who started this post has an app or setting that is causing it or they are intentionally trying to keep people from buying it...Which seems crazy...who would care that much...?

General Game Optimizing Service / "App-Performance-Limitter" on S22 Ultra?

According to some news, the so called "Game Optimizing Service" is availeable on S22 Ultra devices - which potenially controlls about 10.000 Apps of the App-Store.
Can someone confirm if it is installed / active on S22 Ultra on SD & Exynos ?
[Update: Samsung reponds] Galaxy phones appear to be throttling 10,000 Android apps, like OnePlus did
According to recent findings, Samsung is throttling thousands of common Android apps on its Galaxy devices, and without a clear reason.

Pay for the money greedy developer.

Here's a link to my thread, i debloat Samsung firmware including GOS (Game Optimizing Service) for the best performance and battery.
[DISCONTINUED] Samsung Galaxy One UI - Optimization Guide
THIS IS A SUGGESTED CONFIGURATION FOR SAMSUNG DEVICES OUT OF SUPPORT/CLOSED I - RECOMMENDED SETTINGS To Start With - Factory Reset before starting optimisations - Factory Reset after every Major update (One UI/Android) - Remove SIM before first...
forum.xda-developers.com

I remember that Samsung used something like this in my Note 5 and S7 Edge from Android 6 to limit game performance on purpose.
I advise you all to disable this "optimization".

Reports say that the GOS cannot be disabled the old way b'cos it's now system app since One UI 4.0?

Will it help to uninstall insted of disabling?

You can't disable it in OneUI 4.x
It's part of the Kernel now.

Maybe instead of panicking and basing decisions on headlines and mob mentality you think about the reasons why this might have been done to start with?
Most of if not all of these apps will be very poorly optimised in general but especially for the hardware in the S22 series of devices - this means that left unchecked they will use more resources than they really need to, warming up the devices causing thermal throttling to kick in and draining the battery fast (as well as possibly reducing the lifespan of certain components).
This APK keeps these things in check, but for games where you really need more performance you can use gamebooster to switch to performance mode and recovery virtually all the lost power (if not all of it) - making it your choice to sacrifice heat and battery life for performance when you need it, not all the time.

Yeah, I uninstalled it via ADB but it returns after reboot.

Yeah only thing working from the sounds of it is being rooted and using a package disabler but yeah then you lose widevine currently.

I've disabled all it's permissions including "Change system setting", maybe that helps.
Also here it's mentioned that it's possible to disable the GOS for non-game apps, still waiting for answer to how though:

It is more or less the same discussion as we had with the oneplus 9 pro.
I am not seeing bad intend - but i dont't support the overall approach.
Most of theses apps are poorly optimized .... Even if so: That's none of the OS to take care of - especially not if you can't change / edit the overall parameters as a user on a "per App" Solution. I would love to see MS introduce something like this into windows....
Also the oem now actively could impact the performance of an App and the developer ist reliable anymore: "Well Samsung decided our app has to run like this, thanks for buying the pro version, but we can't help you". Wonderfull. And if Samsung has a bad day - maybe we are dropping the performance of some famous apps even more.... cause samsung would love to push the own alternative. Which includes some new advertising service... One could get creative with this stuff.
The reduction of lifespan is also a argument which is... at least questionable. I would argue that this is then poor product design or use of wrong or not fitting-quality components for the job. Makeing up "flaws" in Hardware by Software isn't really a solution to the overall problem

OK, so apparently this GOS thing is what the "Processing speed" option controls. It enables all apps to run at native speeds. I thought it just raised the clock speeds or something. Hmm..

@omnimax
not really. The thing is that the term - "Game Optimizing Service" is a bit missleading.
It is not about allowing named applications to run "native" or "unristricted". Named applications run with predefined ressourcess which aren't by any means "native". It's not about "raising" clockspeeds. It is about restriction of availeable ressourcces.

Nah, this is the same situation as OP did with OP9 series, except US SD user's cant even root and remove it completely so you're stuck at their mercy. If it was configurable, not enabled by default, only affected games and didn't phone home all the time, they might get a pass.... but the way it's implemented is pretty much the definition of malware.
Can't even opt-out
Always runs, with permissions or not.
Phones home with potentially identifying information. (EU people, check out how GDPR is handled here, it's probably not)
Makes your device slow.
The road to hell is paved on good intentions and what not...

I am really amused to see so much discussion on this here on XDA and social media as well. For 98% of the folks, as long as your phone runs smooth and gives you an all day battery life, enjoy it. Many app developers are also not saints. They may leak data and bloat code etc so OEMs need to take the matter in their hands. For avid gamers, they should probably get a gaming machine and use phones only for casual gaming. With current tech limits, gaming on phones will necessitate some tweaks to optimize performance. Apple is polished because it simply stops everything else in the background and focuses ONLY on 1 task on the foreground. And iPhones also do heat up after sometime while gaming.

It's really not the OEM's place to "take matter into their own hands". Don't push your use case on everyone else. Samsung does not know my user case, just like Apple does not know my use case, just like YOU don't know my use case. People bought this (and other, like the OP9) phone partially due to benchmark scores that should translate into performance metrics for their use case. When that's not the case, then they should be mad they got a paperweight. Check out the GOS enabled geekscore, it's basically a GS10. Why should users be happy they got a smooth UI experience when the things they actually want to do on a phone is gimped?
Your sentiment on a gaming machine... are you serious? This phone costs more than an actual mid-upper tier gaming PC. Some people like to play games on their phones, and some games are mobile only.
Again, optimizing by itself is not necessarily a bad thing. They just need to make it an opt-in experience, explain what it does clearly, let the users choose which apps to "optimize", and start letting people use their hardware like their own.

Question What good is a fast S22 SoC if you can never use it? Samsung is throttling all your apps except benchmarks.

Samsung caught throttling 10,000 phone apps—and its own home screen
Samsung's "Game Optimizing Service" throttles just about every app you can think of.
arstechnica.com

Samsung might be throttling the performance of 10,000 apps (Updated)
Samsung fesses up to throttling, and here's what it'll do next

That's sh!thouse

If people think the battery is just okay now, wait until this gets uncorked and watch the complaints flood in. No one complained about the phone being slow but I feel like this could be detrimental to the battery. Maybe they will give us options.

I read an article that said Sammy is going to put out an update addressing that, there's been many complaints.

They should give you the options to control it, it's YOUR phone afterall.
Battery is pretty crap on the S22 series, pushing performance to what it should be from the get go, going to drain it faster, yes.
Honestly, 5000mah is pretty low for such a phone , 6000mah would be nice.

I put the phone on performance mode the day i got it. ZERO ISSUES.

Question S21 plus latest software. Battery life (great)

I dusted off my xda account to let you know that this latest software is great... Battery life finally doesn't drain when not used. (battery drain while not used drives me crazy, wife has iPhone... Always in use, it lasts forever)
Anyway Im the guy that never have problems, not many apps. No smart watch connected. Not rooted, not gamer, no cloud.
My battery used to drain like 15% overnight. Not anymore. It barely uses 40% a day.. Before it was about 75%.
I'm planning to freeze my software update app. Bc whatever they did is working great.
My device is more than 12 mo old, and i use the 85% charge limit (slowest possible charge). Unlocked US model directly from Samsung.

Yay.
Definitely package block updates if it's running well now.

you lucky guy! I'm waiting for the Pixel 7/7 pro and then I'll choose between them and the Zenfone 9. Samsung cheated me for the last time!
My phone is slower than my previus Op7Pro, battery drain is huge and it's always hot. I have it from July 21 but this summer the phone has been unusable under the sun or on the beach because of the huge thermal throttling. I had to splash in the swimming pool while taking photos of my children because it was very hot and went in thermal protection.
Battery life is terrible too, I've to charge at least twice a day even without using it.
Do you think is something that can be solved by the Samsung support?

Turn off global power management, find the battery/bandwidth hogs and deal with each on a case by case basis ie optimize it. All Samsung's should be optimized for best performance.
Package Disabler is something I always use but it's not my only tactic.
Since the N10+ Samsung has lost its balance.
That said my now cool running snappy fast N10+ was once a stuttering, hot running battery/bandwidth hungry hog. It doesn't seem like the same device now, it runs like a bat out of hell. Been running like this for 2 years on the same load. All you can do is try to optimize it.
Samsung Tech support? Bah-ha-ha-ha, don't count on it. Rarely are they helpful, but occasionally you get lucky. Updates tend to break not fix things... think before you click and disable all auto updates especially firmware.

thanks for your suggestion, this night (when my children will fall asleep XD ) I'll try to check. Where can I find the option to disable the global power management?
About the power governor I'm using the mid option named High ( I have Optimized - High - Maximum) but I've tried the other two options and wait I've seen is bad performance (no increase in battery life) or increase of the phone temperatures with no real benefit in the daily use.
I'm hating this phone, I'm thinking to change asap, I'm waiting for the Pixels, hoping Google is able to manage the thermal issues better than Samsung.
About the support I don't mean the one by the phone, I know it's useless , I would mean if my thermal and battery problems can be related to some hardware issues.

It's in Device Care under battery. Individual app battery background settings don't invoke global power management so you can do that instead.
That's just the start. You probably need to use a package disabler or adb edits to disable about 70-80 bloatware apps.
This is how on my N10+'s its configured.
Unlike latter Samsung flagships the N10+ is a well balanced phone in terms of form factor, usability, functionality and power consumption.
It supports expandable storage up to 1tb.

It seems that disabling the global power management the slug mode has been disabled too. I need to check it in the next days if the situation stays like this or not. In any case I still need to block the bloatware.
Thanks for your help
