App killer

I’ve just finished reading an interesting article entitled “Android Task Killers Explained: What They Do and Why You Shouldn’t Use Them“. I for one use ‘Advanced Task Killer’ but having read this article I now wonder if it is something I should be doing. One of the misconceptions regarding Android and your RAM is that we’re stuck thinking along the lines of a Windows machine. The jokes on us.

On Android, having your RAM nearly full is a good thing. It means that when you relaunch an app you’ve previously opened, the app launches quickly and returns to its previous state. So while Android actually uses RAM efficiently, most users see that their RAM is full and assume that’s what’s slowing down their phone. In reality, your CPU—which is only used by apps that are actually active—is almost always the bottleneck.

If you use a task killer of some description you would be doing your phone a disservice by not reading this article. After having read it, even if you disagree with its conclusion, at least you have given yourself the ability to choose.  With that said, I’ll leave you with the following thought which sums up the articles overall opinion. “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.” Indeed, the piece finishes with a number of (obvious) suggestions on how you should go about saving battery life on your phone and improving performance other than killing tasks.
