You DO NOT Need to Manage Your iPhone’s MultitaskingPosted: January 15, 2012
This is a concern that comes up frequently when I’m working with clients or just talking to other iPhone users and I was reminded of it today while reading an article over at Daring Fireball.
If you’re not already aware of it, those running iOS 4.0 or higher have the ability to quickly move between previously used apps. Double-tapping the home button will bring up a list of your previously used applications, allowing you to quickly switch between recently-used apps without having to hunt them down on your home screen every time you want to launch them. There is a misconception however that these apps are “running” in the background.
There is one iOS “tip” that I keep hearing and it is wrong. Worse, I keep hearing it from supposedly authoritative sources. I have even heard it from the lips of Apple “Geniuses” in stores.
Here is the advice – and remember it is wrong:
All those apps in the multitasking bar on your iOS device are currently active and slowing it down, filling the device’s memory or using up your battery. To maximise performance and battery life, you should kill them all manually.
Wrong. Wrong. Wrong. Wrong. Wrong. Wrong. Wrong. There are caveats to this but anyone dispensing the advice above is clearly uninformed enough that they will certainly not be aware of these subtleties.
A lot of people hold the belief that those icons you see in the dock are “running” in the background and slowing down their phone. While this might be true for other smartphones, this is not the case with iPhones or iPads. When you exit an app, your the iphone essentially creates a “snapshot” of the current state of that app and the phone returns the app to that state when the app is re-launched. The app is NOT constantly running in the background, they essentially go into a hibernation state.
So stop worrying about “apps running in the background”. Occasionally I’ll run into someone who has an iphone glitch and closing out all the apps in the multitasking tray fixes the issue, but this is a rarity and usually only happens when people have had multiple apps open in the tray for over a year. iPhones/iPads are designed to be simple, don’t worry about them too much.
