The phones we chose for the testing were the HTC Evo 3D, the HTC Sensation 4G, the HTC ThunderBolt, the Motorola Droid Bionic, and the AT&T Samsung Galaxy S II. We reset each phone to factory settings, with Wi-Fi disabled and 4G on. We set the phones to play a high-def movie on a loop, with the screen at maximum brightness, until the phone battery died.
In order to test whether task killers would help with battery-life issues, we downloaded on five different 4G . Advanced Task Killer is arguably the most popular task killer in the Android Market, and the one that is most frequently recommended. (Note, though, that the developers of Advanced Task Killer make no claim that their app will improve your battery life.)
In the PCWorld Labs, we hate unanswered questions. So we tested an app killer on a variety of phones. Our results indicate that neither side is entirely right. Overall, using an app killer produced an increase in battery life, but one so small that most people wouldnРІР‚в„ўt notice it. And on a couple of phones, battery life remained unchanged, or decreased, with an app killer on the job.
But for everyone who advocates a task killer, thereРІР‚в„ўs another Android user who claims that such tools actually decrease battery life. Their argument: will just restart themselves after an app killer stops them. And all that activity--the app killer stopping processes, and the apps starting themselves up again--will knock bars off your battery meter.
Some frustrated Android users turn to task managers such as Advanced Task Killer to preserve the handset's juice. The theory makes sense: Apps for Facebook, Google Maps, Pandora, and Twitter, for instance, love to start up in the background. If you automatically and regularly stop such apps, the thinking goes, youРІР‚в„ўll end up with longer battery life.
If you have an Android phone, youРІР‚в„ўre probably dissatisfied with its battery life. After all, many phones, especially 4G models, canРІР‚в„ўt make it through the day without needing to sip from a power outlet.
