Nowadays, Android phones are so popular that it can do anything. Unlike other OS, most of the Android applications do not have exit button. When you exit an application using back button, it will get closed. But still there will be some component services running in background. These services consume the RAM as well your phone’s battery. Of course, apart from speed everyone’s concern is battery. If your android phone battery lives more than a day without charging it can be said, “Great”!
There are many task killer applets available in Android Market which will kill unwanted applications running in background. Android Assistant is one of the best application among them as it is a multi purpose application. This has nearly 18 features including, cache cleaner, memory boost, auto boost, app to SD card, startup time, application install/uninstall etc.
Tweaking system launchers can play a vital role in speeding up your system. Default launcher application is consuming more RAM and of course you can find eye candy and pleasing launchers from Android Market. We recommend GO Launcher as it has lot many features like in-built task manager, font changer, theme support etc. You can try a variety of animation also. If you are experiencing problems you can disable some animations also.
Still if you are one with no internet on your android device (well that is hard to believe) you can try killing unwanted applications manually by opening the task manager. Also, if you are using Froyo (2.2) or Later versions, you do have an option to move applications to your SD card. However, you cannot move pre-installed applications and certain applications which need to be installed in phone memory itself. (Note: Moving application to SD card does not mean you are moving the entire application data to card, still you will have some portion left in phone memory)
It is craze for some persons to install applications in phone like anything. Unless you are a frequently using that application or not at all, do not install those applets. Even if you are not using the application, still it will be running in background and consuming your bandwidth, memory and battery.
