Owners of the latest smartphones on various platforms would all like better battery life for their handset. Trouble is we all want powerful and fast devices but this comes at a price with regards to battery life. Having applications running in the background doesn’t help matters either but you can install things to stop this. But do Android task killer apps improve battery life?

Having an android device especially a 4G model you could be disappointed with battery life and need a charge before the day is out with heavy usage. PCWorld have tested an app killer on a variety of Android handsets to see if there is any improvement.

Many Android owners have some sought of task killer installed on their smartphone, and you would have thought it makes sense. A lot of different applications start up on their own in the background, and the idea is if you stop these it will save battery life.

There are some though who argue that once you kill the app it will just start up again in the background, which in practice could use even more of your battery. So this is when it was decided to do a test to see if these kinds of app killers actually have some benefit to battery life. After doing the tests it was found it did make a small difference but one so small most of us wouldn’t notice. It was also found on a couple of devices it made things worse.

Five different 4G smartphones were used in the test with the Advanced Task Killer application downloaded, which could be the most popular one available on the Android Market. There are no claims by the developers of this app that it will help your handsets battery life though.

Each device was reset to the factory settings with Wi-Fi switched off but 4G left on, and then left to playback a HD movie continuously at full brightness until the battery ran out. The application has a number of modes but it was left to Safe, and was used to kill applications every thirty minutes.

The tests found some improvement in the three HTC handsets that were tested, with the Evo 3D showing the biggest improvement at a total of 15 minutes overall. The Motorola Droid Bionic showed no improvement, while the Samsung Galaxy S II lost 2 minutes.

It was found that the task killer apps hardly improves matters regarding battery life, but can free up a little extra RAM for you. Have a look at the table below that shows the results of the test. Do you use a task killer app?
