Multitasking on Your iPhone 6s or 6s Plus
Multitasking simply lets you run numerous apps in the background of your iPhone simultaneously or easily switch from one app to another. For example, music from a third-party app such as Slacker can play in the background while you surf the web, peek at pictures, or check email.
But that’s not all. If you use an Internet voice-calling app such as Skype, you’ll be able to receive notification of an incoming call even if you haven’t launched the Skype app. The multitasking feature also lets a navigation app employing GPS update your position while you’re listening to an Internet radio app such as Pandora. From time to time, the navigation app or Apple’s own Maps app will pipe in with turn-by-turn directions, lowering the volume of the music so you can hear the instructions.
You can also leave voice notes in the Evernote app while checking out a web page.
Multitasking couldn’t be easier — and it has gotten a lot smarter through the years. Now your iPhone can anticipate your needs. If it detects over time that you tend to turn to your social networking apps around the same time every morning, it will make sure the feeds are ready for you.
Double-press (not double-tap) the Home button. You’ll see preview pages, with icons and the names of the open apps associated with those preview pages. Scroll to the right or left to see more preview pages or the iPhone’s Home screen. Tap the icon or preview screen for the app you want to switch to; the app remembers where you left off. (Scroll all the way to the left and you’ll also see a preview screen for the last Home screen you opened.)
Apple insists that multitasking will not drain the iPhone battery or exhaust system resources. The iPhone conserves power and resources by putting apps in a state of suspended animation. Your phone will schedule updates only during power-efficient times, such as when your device is connected to Wi-Fi.
What’s more, as part of the iOS 9 software upgrade, Apple figured out a way to squeeze a little bit extra out of your iPhone battery.
To remove an app from the multitasking rotation, swipe up the app’s preview. Poof, it’s gone.
If you have the 6s or 6s Plus, you need not double-press the Home button to bring up the multitasking rotation. You can alternatively employ 3D Touch. Press down against the left edge of the display and drag to the right. This maneuver takes considerable practice, though, especially on the smaller display of the 6s and especially on phones with a case. If you don’t get the movement just right, you may inadvertently drag an iPhone search screen instead.
