Like their larger computing counterparts, Android-based devices need to be maintained. Problems can start if the internal storage becomes full (or close to it) or if you're running too many apps or background processes at once (which also decreases battery life).
What follows is a description of 10 apps that can help increase the performance of your Android device. Note: A few of these apps require you to -- in other words, you need to unlock the device, giving apps the ability to use full root permissions. (Keep in mind that there's the possibility that you could void your warranty.)
