Then choose a method to export to. It is best to avoid task killers such as Advanced Task Killer. If it starts to run low on memory, it will smartly unload the oldest running apps automatically.

You can also hit the Menu button to access a more detailed "Services" view, that lists exactly which parts of each application are "running", how much memory they take up, and how much free memory is available on your phone. This set-up implies that the goal of killing these apps is to free up memory.

Nowhere on the list does it mention the number of CPU cycles each app is consuming, only the memory you'll free by killing it. As we've learned, full memory is not a bad thing—we want to watch out for the CPU, the resource that actually slows down your phone and drains your battery life. Thus, killing all but the essential apps or telling Android to kill apps more aggressively with the "autokill" feature is generally unnecessary.

Furthermore, it's actually possible that this will worsen your phone's performance and battery life. Whether you're manually killing apps all the time or telling the task killer to aggressively remove apps from your memory, you're actually using CPU cycles when you otherwise wouldn't—killing apps that aren't doing anything in the first place. In fact, some of the processes related to those apps will actually start right back up, further draining your CPU.

If they don't, killing those processes can cause other sorts of problems—alarms don't go off, you don't receive text messages, or other related apps may force close without warning. All in all, you're usually better off letting your phone work as intended—especially if you're more of a casual user. In these instances, a task killer causes more problems than it solves. That said, not all apps are created equal. Many of you have used task killers in the past and actually found that after freeing up memory, your phone works a bit better.

It's more likely that this is because you've killed a bad app—one that was poorly coded, and for example keeps trying to connect to the internet even when it shouldn't. Any performance increase you experience is more likely because you killed the right app, not because you freed up loads of memory or, in many cases, it's just placebo.

Instead of killing all those apps, find out which ones are actually causing the problems. If you really know what you're doing, you may benefit from using a task killer to stop the one or two inefficient-but-loved apps on your phone. Note, however, that this is still a contested notion. A lot of developers including ROM builder extraordinaire, Cyanogen will not even look at your bug reports if you're using a task killer. In this humble blogger's opinion, your best bet is to stay away from regular task killer usage entirely.

If you absolutely have to have that one battery-killing app on your phone, though, kill away—just be aware that when you experience a recurring Android bug later on, the task killer may be at fault. Of course, you can just stop using it to determine whether that is or isn't the case.

With task killers firmly in the better-off-without box, there are still a number of other things you can do to fill the void, improving your performance and battery life:. Watch for Runaway Processes : Previously mentioned Watchdog is a slightly different kind of task killer, in the sense that instead of telling you your phone's out of memory and it's time to go on a task killing spree, it alerts you when the occasional app starts eating up CPU for no reason.

You can then kill the app with Watchdog and get on with your day though honestly, at that point, I usually just reboot my phone. If it happens often with the same app, however, you may want to move on to the next step. If you find with Watchdog or through some other method that a particular app seems to drain CPU and battery life whenever it's running, confirm your suspicions by uninstalling it and seeing what happens.

If an app is causing problems on your phone, you're probably better off without it. Root Your Phone : We advocate rooting Android devices a lot at Lifehacker, but that's because it really is as useful as everyone says it is. You can over- and underclock your phone with SetCPU , install custom ROMs that noticeably improve performance and battery life, and use the ever-useful, crapware-thwarting Autostarts utility to stop apps from starting up on your phone in the first place.

Honestly, with one-click rooting apps like previously mentioned Universal Androot available for most phones, rooting only takes a few minutes to do, and you'll be much happier for it. Update : Many of you also mentioned the root-only app Titanium Backup , which will help you get rid of the pre-installed crapware that comes on most phones, which are one of the worst offenders of phone lag. Thanks to all of you that sent this in! Seriously, Use the Power Control Widget : This may sound ridiculously obvious, but if you aren't already using some form of the Power Control widget, you should.
