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.

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
Sent from my One V
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...
Greenify is probably one of the best apps for battery saving. It will get the most of your device and it will surely save you tons of battery life.
Greenify is created by the famous Android developers from “XDA developers”. The developers from this website are one of the best in the world and they received amazing critical acclaim from all around the world.
Back to Greenify. It is an app that has the capability to reduce the battery consumption on any Android device. Most of the manifucturers still haven’t found the correct solution for decreasing the battery consumption, most of their solutions work by automatically turning off Wi-Fi, GPS, reducing the brightness, etc. They don’t have meaningful effect on your device’s battery life.
Any Android device can do self-initiative and automatic checks about anything new in any application, especially when you install new apps or update them.
Facebook, EMail, Twitter, Google+, Whatsapp, Tango have processes that are constantly working in the background. On top of that, there are is also a great amount of software already installed by the manufacturer of the device (bloatware), as well as the provider whose services you use. Most of these applications are constantly open, consuming the phone’s resources (CPU, RAM), spending your 3G/4G internet, and they are biggest culprits for excessive daytime consumption of your battery.
Read More ...Reviewappandroid.com
The Greenify Donation add on is well worth the few dollars it costs as well. If you get the add on then go into the settings, it makes system app hibernation and deep hibernation options available for use. Greenify is the one app that truly saves battery without freezing or disabling the app. There is no performance loss or app failure when putting apps into hibernation. One thing to keep in mind is that it is regularly getting updated to accommodate new devices and Android updates. Always back up your current version because some updates may not auto hibernate as well as the previous version etc.
If you get Greenify and GSam with the paid add on you will be able to greatly reduce wasted battery drain and quickly identify wakelock services

What do you think about "Hibernation Manager "? What is better?
INTRODUCTIONPURIFY is an FREE APP to optimize your Android devices.
It kills battery consuming apps in the background and prevent it from auto-start.
And the notification box helps achieve the massive unwanted messages from different apps.
With ROOT access, it works more smoothly, here you can obtain ROOT access through KingRoot .
What is Purify
Save Battery Power:
First and foremost, Purify helps extend standby time and save your battery power.
Here is a testimony from a friend, "Now with purify app every 1% battery stays for a very good time while using. No battery waste on Standby".
Speed Up your Device:
By killing apps that insist on running in the background, Purify saves RAM for your device to help it run faster than ever!
And for the applications that utilize larger than average amounts of RAM, these too can also run smoothly after purifying mode is implemented.
Archive Notifications:
PURIFY also helps achieve notifications from all apps in one, and classify them for easier reading
Bloatware Remover:
In root environment, Purify is able to remove bloatware which annoy you day and night.
You can find it in Tools menu where at the bottom of home interface.

DETAILS OF PURIFY
What's installed
#PURIFIY
PURIFY can automatically put closed/killed apps into hibernation mode while running in the background. What's more, PURIFY can also archive notifications for you - it will be like having a 24/7 housekeeper for your device. PURIFIY will be installed in your Data/app
What drains your battery?
#apps,apps and apps!
All running apps, all closed/killed apps, ad-supported free apps even multi-tasking will kill your battery.
It is inevitable that running apps will drain your battery. But what about "closed" apps? In Android OS, even if you aren't using an app, it will continue to run in the background, because it is essentially just doing it's job. So, will "closed" apps kill your battery? Of course, they will, because you can not truly kill them.
Additionally, all of the ad-supported/free apps can drain your battery much faster than others. They not only run in the background but also drain the energy from your processor and use your data connection to download and display new advertisements.
Although the ability to run more than one app at a time (multi-tasking) is great, it can really put a strain on your battery life. You may find that some apps seem really tough, always wanting to run, and we call this "auto-start". These apps run all time and have the ability to destroy your battery, your performance, and your Android experience.
So, what you can do to deal with them? Remove them or purify them with PURIFY 1.0 . I really recommend you try our PURIFY solution because you will never have to uninstall your beloved apps such as FaceBook or WHATSAPP. Not only can you keep them but you will be able to transform them into purified or battery-efficient and energy-efficient applications (no more running in background and no more auto-start drain)
#others
Screen, Bluetooth, GPS, Voice Service, NFC, Wi-Fi, Syncing, Widgets. We know you still want to enjoy the modern technology your device has to offer so we did not do anything to control your hardware in this version of PURIFY. But if you want, please tell us, we will develop more functions to save power for you.
Why is my device running slow
We all know that our device has a limited amount of internal storage and RAM - so, the less free space them has the slower it will perform. The most important thing is that if you do have not enough space you cannot run some larger apps. Your phone needs a little breathing room to run smoothly and if you're running low on space, things can slow down.
Apps which we mentioned above (Running in the background and Auto-start) will not only kill your battery but also occupy your RAM space. Multi-tasking several apps makes it easy to switch between different tools, but there can also be an impact on performance.
PURIFY can also help you to speed up your device and only lets apps the apps you wish to run smoothly run while purifying all others apps. You can control your device completely!
How PURIFY works
#Purifying mode
Enable purifying mode will make your device run like a champ and extend standby time significantly. PURIFY will Intelligently recognize which apps should keep running ( like music play, dialer, VPN and so on ) and which one should be purified. Purifying an app means that all functions (service, periodic task, event receiver, alarm, widget update, push message) of this app will become out of service except when you are running this app manually. If PURIFY detects that some useless apps are running in the background she will recycle it from RAM and prevent it from auto-start. Of course, you can also choose manually which ones you want to keep.
#Purify Apps
In this menu, you can manually choose which apps you want to keep and which ones you want to put in purifying mode. You also can choose if you want to auto recycle it or just want to block the auto-start process.
#Purify Notification Bar
In this menu, you can choose to archive notification for specific applications.
#Purify All
When you feel your device slowing down just click the "Purify All" button on the home page of the Purify app. All apps running in the background will be closed.
#Bloatware Remover
In "Bloatware Remover", just choose apps you want to remove and click removing button. Charge in your own device, remove bloatwares you don't like.

Nice app. It has really improved battery life significantly. It also helps to declutter the notification area. One suggestion, please fully translate it in English. There are still some Chinese literals.
First I wanna congratulate the developer for this awesome app.
This app is just sick, and really works. Finally a battery saving app that really do work and push the limits of our battery usage.
Basically this powerful app use both greenify and servicely features combined together all in one and more. You get to control everything or u can let the app do it for u.
I installed the app today when I had 65% left on my battery but I'll do a full day usage tomorrow to see how well this app but for now I got to say just wow amazing.
Since lollipop I've never get this battery life.
