"Task killers aren’t just useless – they can reduce performance. If a task killer removes an app from your RAM and you open that app again, the app will be slower to load as Android is forced to load it from your device’s storage. This will also use more battery power than if you just left the app in your RAM in the first place. Some apps will automatically restart after the task killer quits them, using more CPU and battery resources. "

Thats why we can swipe those apps away.. ?

As I understand it swiping apps away only tells the system that is acceptable to free those apps from memory early, but it doesn't necessarily " kill" that app immediately. The recent app list talks with the system whereas the task killers typically just force close the app.

Yup. Swiping the apps do not necessarily kill them.

I still use advanced task killer with 4.2.1, and my battery life is double that of the times I don't use it.....this is just another one of those conspiracy theories with no evidence to back up the claims If I put my phone down after using google maps, my battery will die within 2 hours, even if I just unplugged it after fully charging to 100%.....if I kill maps, my battery will last me another 8 hours of normal use.
....and remember....itr's not always about battery life with task killers. New apps are RAM hogs because new devices carry more RAM capacity. Having an old device means if I run google chrome, I can't run anything else because my phone runs like sh!t when chrome is running....so I have to kill it. As soon as I do, my phone starts responding again, and is finally usable!!!
....so before you just go spouting off about your unfounded claims in regards to task killers, maybe you should do some research and ask those of us who do use them if they actually help, instead of just assuming what you read is the only truth to the story.

Is cpu-z accurate?

1.4 free ram out of 4gbs? What?
I disabled and uninstalled all bloatwares no recent apps opened
Only cpu z is this for real? ?

Whats wrong with that?

1.4gb is plenty of free ram, why do you need more?

I know but why? 2.3gbs of used ram for what? Display?os?and what?

2639 MB
I saw this and wondered about it so I got cpu-z from the play store to check it out myself. Mine says 2639 MB free. Check your auto start and see what is set up to run automatically.

Android and hardware, trust me when i say this, the more you use the better is.

2150(54%) free for me. ROM Prism BareBone+Project T kernel.

Memory usage in android isn't as you know on a standard PC. Android OS uses to free RAM when is needed. If not need it use to maintain apps previously opened in RAM to successively opens them faster. I know this is a really easy explanation. To know more in deep the Android memory management you have to study it from official SDK manuals. (I got 1.7 gb of free RAM)

the flipside would be too much unused ram.
*think the recent samsung fiasco where it was force closing every app the moment you exited it*

The more ram available, the more ram an operating system could and should use. A certain amount should be free for new threads and tasks, as well as timer-initiated background tasks, but the more ram you have the more the system can put things into it and out of a swap file or cache. So, for our devices, having that much ram means that most, if not all, of the common open operating system components are put into ram and stay there. Then it loads applications as you open them, and will only clear them out if a) you run out of ram or b) you manually close it/stop app. It used to be that, back in the old days of operating systems, there wasn't as much automated memory management to keep things smoothly running. Things pre-Windows XP had a nasty habit of gobbling up ram for things that aren't even being used and then not release it. For Android, though, and especially at this point in its existence, our devices have plenty, which results in the smooth and hiccup-free experience we get using the Zenfone 2!
There, all my years of IT experience contributed to something today.

Thanks for the Infos! now i know

Is there a kernel with swp/swap support?

For more info on swap memory, check this article.
I know swap memory shouldn't be necessary on Android, as we already have ZRAM, however, that still takes up RAM space and we only have 4GB at our disposal.
Plus, 512MB of ZRAM is not that much, even if it's compressed.
I use a lot of apps. Most of them don't run in the background, so that's fine. However, the one time they do run is just after a reboot. Then they all fire almost at the same time because they have on-boot listeners and this clogs up my ZRAM and RAM completely causing everything to crash up to System UI.
When System UI resets after a while, all the apps get the on-boot command again and it repeats... The only solution I have right now is using System Monitor 2 to stop the processes continuously for a minute or so, until all the apps have gotten their on-boot command and the phone runs normally.
I've tried the background check and battery savings settings for those apps, but they still run on boot :/ I also looked at some apps that could block apps from starting on boot, but they all seemed a few years old, back from when phones still had 1GB of RAM.
So, as SWAP helped my laptop from crashing every time my RAM filled up, I thought it would help my phone as well!
The stock kernel however doesn't seem to support swap (which I checked with "su cat /proc/cpuinfo" as described in the article).
Next I tried ElementalX which also doesn't seem to support it.
Any other kernels I should try?

I'm not sure about Kernels with swap support but I use an app called SD Maid to turn off apps run at boot command. That app is constantly updated and does the job well.

How do you do that exactly? In appControl I can see which apps run at boot and I can uninstall or freeze the app, but not disable it booting as far as I can see

It's under app controls receiver manager. You can turn off start at boot and any other services it has.

Yess got it! Thanks! Let's test if that can solve my problem. I'm still curious towards a swap enabled kernel though, also for other reasons

Hmm for some reason all apps still wake after the boot is finished, even though I blocked them all with SDMaid. Really odd...

That is odd. SD Maid has worked really well for me. I don't know if it makes any difference but I'm using the Pro version. I've had it so long I can't remember what the difference between the free and pro versions are

I'm also using pro, so that's the same. But yeah, when booting I notice apps like AliExpress still starting when I disabled its boot receiver with sdmaid and even blocked it from running in the background in two places of the Android settings (battery saving and background check)

Samsung "notes" app - running too much in the background

Hi all
As you can see in the image, the Samsung Notes app is running wayyyy too much in the background, eating up my battery. This is even after I make sure the app is closed after using it!

I tried to set the app to go to sleep, but this was not possible as it is a Samsung dedicated app. I couldn't even optimise this app either. The only solution seems to be "force stop"ing this app, which I prefer not to do as I use the app once or twice a day to write notes.
Anyone have any thoughts on how to stop this app from running so much in the background?

Possibly notes is trying to continuously update to the Samsung Cloud?

Thanks for your response, but nope - I've disabled everything from being able to backup to Samsung cloud

Personally I don't understand why the applications stay active in memory after I stop using them, since I can't tell the difference even if my life depend on it if apps is cold started, or starts from memory, either way it starts almost instantly, so yes I would definitely force stop it myself, especially that I feel this "feature" of all apps staying in memory is more for advertising purposes than anything else, especially now. There is a switch to either put app to sleep or not allow background activity, one is under apps inside battery menu, another under battery usage menu. I'm trying to limit all apps from running in the background, except for map which needs to be constantly updated for traffic, but what a pain in the neck it is, there are over 400 apps on the damn phone.

Disable or uninstall this trashware.
Switch to an app that stores your notes in a standard format such as text files etc so you can always read them in the future.
Finding a good free office app is now almost impossible for Android. I use an old copy of Kingsoft WPS Office. Today's newer versions though are pure crap unless you pay, pay, pay.
Used Samsung Notes on my S4 but restoring them became a tedious nightmare when I migrated to the Note 10 platform because Samsang "upgraded" their app so it wasn't backwards compatible with their older version's note files.
Don't trust Samsung with any data you care about; they will make it obsolete by their time table not yours.
Thanks for nothing Samsung... feel the wuv for the rabid gerbils in the box.

Question AOSP ROM's are closing recents automatically?

Good afternoon!
I have a question about AOSP based ROM's. At first I thought this was only occurring in the Nameless ROM but I can also find this behavior on other custom ROM's. It seems that apps are getting closed automatically after some time, as if I would go to the 'Recents' screen (or however this screen is called) and I would swipe those apps away.

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
This is definitely noticeable when I wake up in the morning, almost all my apps are gone from Recents while I almost never swipe any apps away. I find this behavior not efficient since my phone never makes use of the 12GB RAM which I've spend extra money on. Here you can see that only 7 GB is actually used (including cached processes).
When I open up all my apps at once my RAM usage goes up but after some time it seems to close apps and it goes back to 5-6 GB of usage or so.
I find this frustrating. I have an iPhone 12 from work and I use that phone rarely. But a week later I can expect my app to still be open where I left it.
In the ROM's I tried, I tried disabling any battery savers if there were any, without result. I also have FKM installed and tried changing some memory related kernel settings which did appear to have some effect but that also might be a placebo and tbh I'm not fully aware what kernel settings I should apply.
TLDR: Can anyone advice me how I can stop my AOSP rom from clearing apps in the background?
Thanks for your input
Kind regards,
GolovaRaoul

Hi,
I have not tried any custom ROM yet, but I can confirm that default ROMs for "OnePlus, Xiaomi, Samsung" are all doing the same behavior once the phone is setting down and not being used for a while "sleep mode" this actually good in my opinion, it will automatically close all apps except the apps you are choosing to not to be closed "locked apps" in oxygen os, you can select multiple apps to prevent them from being closed during night or even when you tap "close all" button.
So, I think this is an Android optimization to save battery during night not only in AOSP ROMs.

Thanks for your response
Well I don't like this behavior personally. It takes time and processing power to re-open apps and navigate them back to the stage where I had them before. I need to relaunch Spotify 5 times per day which is annoying and I really shouldn't need to on a flagship smartphone with 12 GB of RAM.

This actually not belong to RAM capacity itself, it is system implementations and how should apps behave. As I said it will only close the apps during "sleep period" and you can select multiple apps that you want them run in background all the time see attached photos.
You are welcome

Yeah you could be right about the behavior. I still want to change it tho. And by default, AOSP does not have something like 'memory locking' and this is a feature of Oyxgen OS.
