Android's ability to multi-task applications can be seen as either a good or bad thing depending on who you talk to. It's great because those productivity users out there will enjoy being able to accomplish a decent amount of work on the go. Conversely, it can also strain the battery as some apps remain to be dormant, but running in the background even when you're not using it. T-Mobile is dipping their fingers in trying to find the perfect balance for your Android powered phone
with their Device Tune-up app. This isn't just your ordinary kind of app killer because it was designed to work in the background and do all of those essential duties you'd normally forget to do – which ultimately provides you with a better overall performance out of your handset. Thankfully it's in beta testing, but you're going to need to meet a few requirements before you can start checking out this nifty app. First and foremost, you have to be a T-Mobile customer and have the latest version of MyAccount on your phone. Lastly, you'll just simply need to have a microSD card on hand. Now it should be taken into account the consequences of what can happen to your handset if it's running a custom ROM of some sort – the Device Tune-up app hasn't been tested for them and Android 2.2 Froyo as well; so be careful.
