Great task managers for Android

Great task managers for Android
So you have this fancy new Android smartphone that you just can’t get enough of. You're texting and tweeting and browsing and downloading and pretty much anything else that’s imaginable. While you are using your smartphone nonstop, you might have noticed that your battery drains rather quickly. In fact, you could probably go as far as saying that the battery life sucks big time. This is because every little thing you do, every application that you open on your Android smartphone continues to run in the background even when you aren’t using it. If you want to know what applications are the best when it comes to helping improve your Android’s battery life, read on.

The best and easily the most popular task killer is appropriately named Advanced Task Killer. Aside from being very easy to use, it is very effective. What this app does is list everything that is running on your phone’s background. Everything listed has a green check mark next to it which means that app will be closed when you press the “kill selected apps” button. If you want something to continue running in the background, such as a streaming music app like Pandora, just uncheck it. Moreover, there is a setting that will kill applications automatically. It’s simple, effective and won’t cost you a dime.

Another popular app that can greatly improve your battery life is called Juice Defender. Fortunately, this is another free app although there is an optional Ultimate Juice add-on that will run you a few bucks. For now, let’s just focus on the basic app. Truth be told, this app isn’t very basic at all. There are a few different task manager levels to choose from such as aggressive and extreme. Juice Defender does such things as turning off data when you are not using it. Trust us when we say that goes a long way in improving your battery life. The app will actually show you in the notification panel how much of an improvement you can expect to see. This is a highly recommended app.

Advanced Task Manager is another great app worth considering. Don’t let the name or the logo fool you, this application is from a different developer than Advanced Task Killer. The main purpose of this app is to save battery life, speed up your phone, free up memory and of course kill tasks. It has been downloaded a few hundred thousand times for the cost of nothing. Some other nice features include the killing off apps when the screen shuts off, one-click kill widget, quick uninstaller and even support for Android 2.3 (for when anyone not using the Samsung Nexus S gets it). Give it a try, you won’t be disappointed.


The name advanced gets used a lot for these types of applications, and that holds true for another solid battery saver called Advanced Battery Improve. This application takes features that make others so successful and blends them into one package. When you first open the app, you will notice a list of everything that is running in the background, similar to Advanced Task Killer. It will also turn off things such as data when the phone isn’t being used. The developers boast that the app will improve battery life as much as 30%-50%, so give it a try. It is also free.


There are plenty of other applications to consider. You might also want to try out Android Booster and Super Task Killer 2011, all of which are free. Some paid apps worthy of some serious consideration are System Panel App/Task Manager and the Pro versions of Advanced Task Killer and Advanced Task Manager. However, the four that we detailed above should suit your phone nicely and get the job done. So take that new fancy Android phone of yours and text, tweet, browse and download a way because now you know what applications to download to make your battery life suck a lot less. Tell us what you think of these applications in the comments below!

Task killers are garbage. They don't do anything besides mess up your phone. The galaxy linup (or anything by samsung) already has this tool. The HTC products are equipped with one as well. Don't waste your time getting these apps. They drain the battery and resources more than the apps do. Android automatically closes things that aren't used after awhile.

Definitely true. The task killers are pointless, and actually drain more battery. What happens is you kill all your apps and everything stops running, all the apps restart back up. It takes more battery to restart the apps than to just leave them running. There really is no way to save battery on these phones...

Rubbish. Before using ATK on my Desire HD, I was lucky to get 8-12 hours of use before a recharge. Setting it to kill apps on screen off allowed me to stretch this to about 20 hours. Background apps are battery killers, especially the ones that update and require constant data calls when the screen is off.....

Glad Samsung had the decency to include a task manager in the applications menu. Advanced Task Killer is worthless...had it on my Droid X but uninstalled. You close down apps and go back into it 2 mins. later and everything you just eliminated is running again even if you didn't go into it.

task killers do exactly what they claim. If you leave your phone on for 10 minutes there will be 8-10 programs running, usually looking for updates, or they call themselves "running services". Most are running needlessly unless you check the weather, stocks, facebook, email, blockbuster movie releases etc... and anything else you intalled on your phone every 10 minutes. Advanced Task Killer is harmless and works great!

This is from Google directly on task/application services. http://android-developers.blogspot.com/2010/04/multitasking-android-way.html Translation: Don't use task killers.

Task managers work great if you have a phone running eclair or donut, I'm not going to say they don't. But if your phone is running froyo, they're useless. With froyo it came with an update that disabled the ability for an app to kill other services or apps. If you are running froyo your better off using the installed task .manager or just doing a battery pull if the phone is lagging

If you're using a Task Killer/Manager and you think your phone is broken. Remove the damn app and restart your phone before going into a store to get it serviced and whine about how your Droid sucks and you want a free iPhone because of it.

Dead-on with that one, sir.

Honestly I can't believe PhoneArena ran an article on Task Killers lol do they know nothing about Android?

10. justworkin unregistered

Your first mistake is thinking that Phone Arena has any real journalistic integrity. To me it seems more like a communal blog written by like minded individuals that share a common hobby rather than a professional organization that takes pride in it's journalist neutrality and ability to do factual research. Think of PA this way and it will remove some of your frustrations towards their collective lapses in profesionalism.

Oh I forgot to mention the only real Task Killer like app worth using (for root users anyways) is Autokiller Memory Optimizer. I like how PA didn't mention it.

It is simply not true if you leave your phone for a while that Android will kill unussed apps. One hour ago i lefft my phone (galaxy S with froyo) with Browser, Talking Tom, Talking Santa, and many more. None of these were killed by system itself.

12. a33a unregistered

Actually if you read this articlehttp://android-developers.blogspot.com/2010/04/multitasking-android-way.html ; the apps have the appearance that they never close.

The Galaxy S lineup got Froyo? This is news. Even the leaks didn't promise it till the end of February. Hmm.... And for the love of God pleease sttop tyyping likke thiis!

Why would this get posted on here. Task managers are the worst thing that can be put on your phone. I took my original android phone (Eris) and went to my verizon store and this clown tried to tell me that the reason that my phone was messed up was because I didn't have a taks manager. I just laughed at him snatched my phone out of his hand and went somewhere else. They do no good to your phone.

obviously you know sooo much that you needed to go to the store to start. What was wrong with it? you dont even know do you? I guess when I grow up Ill know it all too. dumb asses!

First off, I am not trying to defend these apps, just trying to understand. When my phone is running slow, I open up advanced task killer, kill what is listed, and it immediately improves my phones performance. If these do not work, what is responsible for the reduced UI lag and more responsive applications? I have an HTC Hero so I am still on 2.1 and I am holding out until this summer for a new phone. Does the version of Android you are running have anything to do with it?

using your task killer and keeping the memory on your phone clear (erasing texts/ not downloading too many apps etc.) are the best ways too keep your Hero running smoothly. My GF recently had the Eris and its Basically the same phone. I work on these phones everyday and I cant tell you how many of these jerks try to come into my store and tell me how to do my job. If they know so F'ing much they wouldnt need me or my associates at all but they dont. They read some BS or get info second hand from some dip shit and now they know everything, sound familiar? any how your fine and good news, your next Droid device will have plenty of memory for all the AP's you want. I currently have a droid 2 running FROYO and I still use ATK ( for FROYO) just to keep it moving along. And too the guy with the Fascinate. Your phone is SHIT and dosent have 2.2. Unlessyou got it hacked which just makes you stupid....good luck.

Ah, a fellow wireless employee. Your comment brought tears to my eyes... I feel your pain. In my area we get the worst kind of idiots as customers. I ditched ATK and use Fast Reboot very infrequently. Not exactly the same purpose as ATK but my Droid X got slightly better battery life with it. :o)

advanced task killer works great on my phone, and a lot easier to close apps with than google's built in method, also I can get my Optimus to last up to 3 days on a single charge using this, Im luck to get a day and a half without using it. So it works for me. If its messing up your phone, that's probably only because fo a combination of that app with another thing you did to the phone.

Bang on mate. I've had the exact same experience.

task killer no task killer...the real question is why does one have to download extra utilities for their phone hold a decent amount of battery life. Personally i get a day+ on my Fascinate...maybe b/c i don't have Froyo on mine like Bizarro but its kinda ridiculous that most Android devices suffer terrible batt. life. My gf has an EVO and her batt. lasts about 6 hrs. tops.

26. Bizarro unregistered

If we are talking about built-in web browser, sometimes it takes more than 60 MB of RAM (depends on web pages and cash) and slows down the overall performace. The only solution is to kill it with a task manager. Yes, System Panel kills most apps eve non Froyo, however there are several apps that cannot be killed. I simply can't accept the fact that most apps don't have the "close or "exit" function. OK, there are some like Fring, Skype and some more.

Task killers are useless. Read numerous above reasons.

For those who think task killers will save battery life - they do not!! Read up at XDA.com for more information. They actually can make your battery run harder, as the ANDROID iOS, ecspecially with 2.2, is designed to end tasks when more RAM is needed.

29. networkdude unregistered

uh...you're an idiot... there's no such thing as ANDROID iOS...its either Android OS or iOS....
