Multitasking in iPhone: what it is and how to use it

Multitasking in iPhone: what it is and how to use it

The more applications there are on iPhone, the more often you have to switch from one to another. What actually happens to apps when you close them by pressing the Home button? Yes, yes, I am hinting at multitasking, which was implemented on apple devices after the release of iOS 4.0.

Multitasking is a feature that allows programs in iPhone to perform certain tasks in the background while the user is working with another program. This feature is supported by iPhones 3GS and newer. What does it look like? Launch an application, and then double-click the Home button.

The screen will immediately rise, and the multitasking panel itself will appear at the bottom: a shelf with icons of the four most recently launched programs. Thus, you can quickly switch to one of them.

You can scroll the shelf to the right to get to even earlier launched applications. And if you scroll the shelf to the left, you will see a quick control panel for the music player: the Play buttons and the next / previous song. Usually this is a standard iPod, but if the last one you launched was some other player, its icon will be displayed in the multitasking panel. Or, if the last played file was played in the browser, the Safari icon.

In addition, there is also a convenient screen orientation lock button – very convenient if you are working with the gadget lying down, but do not want it to automatically rotate the screen. Flicking the multitasking bar to the left again will take you to the volume control.

It seems that this is incomplete multitasking, but just convenient switching between applications. But it's not that simple. Some applications actually run in the background, i.e. even when they are not running, but minimized.

First of all, these are:

– background audio: various applications playing music will do this, like a standard iPod, in the background along with other applications;

– IP telephony applications such as Skype are able to receive calls and messages in the background;

– continue to work quietly against the background of other applications and navigation programs, so now you don't have to keep the tracker program open all the time to record your GPS track;

– apps that support push notifications will also receive them in the background. Thanks to this, applications can inform the user about any events occurring on the device: an incoming message, the start of a TV show, or any failure.

– sync with iTunes, iCloud, automatic file downloads, check email. And one more convenience for impatient users: if, for example, you send a post to Twitter or upload a photo through a client of some social network, then you do not have to wait until it is fully loaded. You can close the application and move on to other tasks, and the file will download quietly in the background.

Applications in the background seem to freeze, less RAM is allocated for their work. But if there are too many of them running, and even such gluttonous ones as GPS navigators, then the performance of your iPhone may noticeably drop. Therefore, sometimes you should still clear the multitasking bar.

This is done simply: double-click the Home button to open the multitasking panel, then hold the application icon with your finger until it trembles, and a red minus appears in its upper corner. click the minus, and the application turns off completely.

Personally, I was not immediately used to multitasking when switching between applications, but then it turned out to be really faster and more convenient. This assignment for double-pressing the Home button is much more useful than the one that was on previous firmware (if you remember, double-clicking the Home button then returned to the first desktop).

Multitasking is supported on iPhone 3GS or later, iPod touch (3rd generation or later), and all models iPad. You can also read more details here
