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.
