So i saw many posts on which people have asked as to which task killer should be used !
and then i stumble upon this site which provided me the details,
i just complied info

Android Doesn’t Manage Processes Like Windows
Most Android users are familiar with Windows. On Windows, many programs running at one time – whether they’re windows on your desktop or applications in your system tray – can decrease your computer’s performance. Closing applications when you’re not using them can help speed up your Windows computer.
However, Android isn’t Windows and doesn’t manage processes like Windows does. Unlike on Windows, where there’s an obvious way to close applications, there’s no obvious way to “close” an Android application. This is by design and isn’t a problem. When you leave an Android app, going back to your home screen or switching to another app, the app stays “running” in the background. In most cases, the app will be paused in the background, taking up no CPU or network resources. Some apps will continue using CPU and network resources in the background, of course – for example, music players, file-downloading programs, or apps that sync in the background.
When you go back to an app you were recently using, Android “unpauses” that app and you resume where you left off. This is fast because the app is still stored in your RAM and ready to be used again.
Why Task Killers Are Bad
Proponents of task killers notice that Android is using a lot of RAM – in fact, Android stores a lot of apps in its memory, filling up the RAM! However, that isn’t a bad thing. Apps stored in your RAM can be quickly switched to without Android having to load them from its slower storage.
In summary, you shouldn’t use a task killer – if you have a misbehaving app wasting resources in the background, you should identify it and uninstall it. But don’t just remove apps from your phone or tablet’s RAM – that doesn’t help speed anything up.
Empty RAM is useless. Full RAM is RAM that is being put to good use for caching apps. If Android needs more memory, it will force-quit an app that you haven’t used in a while – this all happens automatically, without installing any task killers.
Task killers think they know better than Android. They run in the background, automatically quitting apps and removing them from Android’s memory. They may also allow you to force-quit apps on your own, but you shouldn’t have to do this.
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.
Whether RAM is empty or full, it takes the same amount of battery power – decreasing the amount of apps stored in RAM won’t improve your battery power or offer more CPU cycles.
hope u understood!
words of wisdom by fellow-mates
go into settings - apps and see how many running apps you have. now go to cached apps and see there, how many apps there are. you see? nearly 50% of those apps discovered by you in the processes are apps that you didn't opened ever but they are still opened and running. why? because that's how linux manages its resources. instead of having free ram for no use (what's the point of having 14gb of ram when you only use 1gb), linux fills all the ram blocks with useful apps or apps that you are running frequently so that when you call that app, it will bring it on the screen almost instantly. this my friend, is called multitasking.
and no, you are wrong. if you use a task killer killing the apps every 10 minutes, the cycles the whole system does - opening again apps and caching them, task killer closing them - results in much more functions done by CPU => more battery spent. even if you say that the battery life its the same, you are wrong. when using a task killer IT MIGHT drain your battery with 0.1% per hour. it's not that much, but IT EXIST.
oh and yeah, one thing: android has its own task killer. that's why you don't need one app to kill your other apps. because android its doing it by itself. if you don't believe me, strip down one kernel, open the init.rc file and find the values for task killer.
I've never used those programs, I like to use what the phones have by default
But is good to know anyways
I agree with that...to an extent
Auto killing apps is plain stupid, but I do believe in killing certain apps. In a perfect world heavy apps would just be uninstalled, but plenty of useful apps without good replacements are fairly heavy, and it helps to kill them. E.g. after exiting a game I will kill it because its hogging up valuable ram by running in the background, while still using he same resources it uses at the forefront.
I understand that android, and Linux should manage ram well, but more often then not some app is just out there slowing my phone down. Even an hour later of not using that app, it'll still be in the background using up a lot of CPU and ram I don't have (more importantly battery). Android is great at managing smaller apps, but in my experience, it sucks at doing the same for larger apps.

I don't use automatic task killers, those that are constantly running, but i do kill unused tasks and apps with no reason to be still running. Google services is a common example. It will launch at boot and keep running peemanently, even if you never launch a google app, google services is running, why?
A lot of apps, mostly the free ones, get revenue by reporting anonymous usage statistics (not so anonymous in some cases). So they stick a running service even if the app is never launched again (sometimes even if it isn't launched in the first place).
To sum up, killing everything is bad, but leaving everything to run free can also decrease performance. This can be observed on an android device that has been running for a long time, versus an android device that's just been reset.
some unused tasks will repeatedly rerun even if killed.
This will further decrease battery life and affect performance as resources are needed to keep restarting it.
The best way is to ignore if it takes a small portion of resources or to uninstall the app. Rooted users may disable the triggers via certain apps.

In phones with very low RAM, this becomes a necessity.
Switching programs take up a lot of time to process unless there is a sizable free RAM

let me tell you something about google services...
when you installed your rom, you had to check two options from google services - location and another one.
if you are on stock, those options are available in settings also.
the google services are needed (you are running a google os, right?) because without it, the location feature will not work, the play store will give you headaches and not to mention, google now that needs that service like water.
if you kill that process over and over again you will not gain anything because that service will keep restarting it until you will give up. ah, you will loose a massive amount of battery if you do so
another thing, the google service is a system app. system apps have priority in resources so even if you kill now, as i said, it will restart after a few seconds because some apps that you are running are requesting that service.
as someone said here, yes, even I kill games after I stop playing, BUT, I do it from the task manager built in. Settings - Apps - Running apps etc.

task killer
Well, i think a task killer is useful. It sometimes helps to speed-up the phone a bit.

No that is wrong.....it consumes more ram it self

Normally to kill a process I use the Running Tab in Apps, If any recently opened app which I feel should be closed is open I kill it!Though I leave the google services untouched!
Stopped using Task managers and Battery saving apps long time ago!
Want to really save the juice? Try Under Clocking! and killing the bloatware(saves RAM too!)
I used to have a task killer but the more I killed apps, the slower my phone was, so I eventually ended uninstalling it.
great post. lots of usefull info!!
Instead of using a task killer to keep on eating your battery life, simply either delete the app or disable it in your system if it's a system out (eg: default browser, bloatware, etc).

Assuming you are replying to me, your response is a bit ambiguous...
Don't know how many of you saw this, but I installed it last night, and it's awesome.

Basically, it allows you to stop apps from running in the background without disabling them. You can still run them like normal, but they don't eat up RAM when you're not. It does stop background functions, but many of the apps I see running like this don't do anything for me in the background anyway. YOU determine what runs in the background instead of your apps.
It doesn't work with system apps, these need to be moved to phone storage before Greenify can take control of them.
I've noticed a definite improvement in available memory and multitasking.

You will spend more battery in killing those apps. ram is supposed to be filled up, the only answer to run more apps is to get more ram , not kill running apps.
Did you read the post? It's not a traditional app killer. It prevents them from running in the background at all.
Installed this a few hours ago. Definitely smoother phone, and moderately better multitasking. Been trying to find a way to get rid of pesky Facebook which uses like 25 mb of RAM just to send you push notifications and sync your calendar.
You may need to convert Facebook to a user app first. It can't do anything to system apps. I did it with mine and it's now behaving.

I am using the stock Moto G ROM + Xposed and Gravity box + Faux @ 1.6gh/z, I have found this combination to provide an excellent and stable CM11 like experience.
In the CM11 forum thread, I have found several references to "Greenify". I have already installed the free version but found that this could only be used to gain a small amount of RAM.
For info, I currently have 21 running processes and there is approx 360 mb of free RAM.
I do see the possibility of gaining maybe an additional 200 mb of ram free if I use the Greenify paid version as it apparently can be used to hibernate system apps. I also understand that I can Greenify messaging apps such as Whatsapp, Skype, Viber yet they will continue to act as if they are running (ie. notifications etc), is this correct?
My question is this. If I can increase the free ram to say 550mb what will the phone gain from doing this? I mean, will I notice any real difference in the phones performance or Antutu performance etc. Also do the Greenify'd messaging app's notifications continue to work reliably?
I would be pleased to have your comments. I ask the above because the phone is working well and it is responsive and reliable. I don't want to add this app if there are any potential negative effects.

Greenify isn't much made to free ram but to prevent background processes to stay alive and drain performance/battery
And that's you, user, that choose which app to greenify so no worry about messaging if you didn't greenify it

@matmutant Boy - Thanks! that was a quick reply, I had just edited the 1st post when I already saw your reply. Ok, so its more battery saving orientated, I didn't realize that. Battery life is something I find hard to quantify. Certainly the Moto G is doing a lot better than my N4. My wife is using the Moto G and with average use she gets up to 48 hours of use, (she usually charges it every day but does forget sometimes).
I recently checked it and at that time found it was 20.5 hrs on battery, with 26% screen ontime (44 mins). Battery at 78%.
With Greenify I guess the only way to see the difference is to buy it and then check the battery status by measuring the drop in battery percentage over a fixed standby period over several days.
So its a good app right? It almost sounds like Greenify is modifying the processes to become more iPhone like in order to improve things. That's my angle anyway.
Yet another question. I decided to purchase Greenify. What I have found is that Greenify Gives me a choice when trying to Greenify system app's. ie. The message I get is "Sorry, system app is not safe to be greenified in general. Then the question "insist" or "cancel" I am afraid to try "insist"!
I am confused as to what I can really achieve with Greenify. I would appreciate some advice. He is a complete list of the processes currently running on the moto G. I would appreciate a short guideline as to what can and cannot be achieved with Greenify.

Is it normal, that system is using so much ram? After restart it shows around 1.5gb ram + little build up app cache. After 2-3 hours it goes up to 5gb of system usage.
Most of system apps preinstalled are disabled or forced to stop. Not using greenify, amplify or xposed. No substratum, kernel tweaks etc.

The real question here is - Is this impacting the performance in any manner? Is there visible lag when using the phone extensively? If yes, then it's a problem. If no, then I wouldn't be concerned because Android has always been notorious with RAM management. Try opening and using a lot of apps and then minimize, then try opening them again and see if they retain the states you last left them in.

I have Pixel 2XL as well and most of the time I have ~2-2,5 GB of RAM usage with apps preloaded. It's plenty fluid and responsive, maybe just a tiny bit slower (if any) than OP6.

Pixel is Google's baby. It'll always be the most optimized Android device. I wouldn't compare those too. But then again if the performance lag is visible then it's a problem, else not.
It's suppose to use up the RAM. Unused RAM is wasted RAM.
I am experiencing the same thing, I went to developer mode and set the background service to none, and installed greenify to force hibernate the services.
I was wondering the same thing, why is it going up to 5 gb ? And to answer someone's question from above, no the device does not slow down ( at least I haven't experienced slow downs ) but I always clean recent apps and I'm never opening more than 4 Max 5 apps
Why wasting time about worrying why system apps run in the background using the ram which is supposed to be used just for this manner. I don't get it. The system runs perfect on the 6 ...
Start using your using device, not developing any problems where none are existing.
Enjoy your devices.
