How to switch to Low Power Mode

Your iPhone or iPad will automatically switch to Low Power Mode when the battery drops past 20 percent (and switch off when a recharge takes it to 80 percent), but if you want to get more runtime from a charge, you can switch it on yourself by going Settings > Battery.

Low Power Mode reduces or affects these features:

  • Email fetch
  • "Hey Siri"
  • Background app refresh
  • Automatic downloads
  • Some visual effects
  • Auto-Lock (defaults to 30 seconds)

When Low Power Mode is on, the battery in the status bar will be yellow.

How to make an Emergency SOS call

To make an Emergency SOS call on iPhone, you simply tap the power button five times in rapid succession.

This starts a three-second countdown -- along with a blaring alarm -- during which you have the option to cancel the call. If the process isn't aborted, your iPhone will automatically call the emergency services.

How to use the Magnifier feature

The Magnifier app works a bit like the Camera app, but gives you greater power to zoom in on the image (beyond the point where you'd be able to take a decent photo) as well as access to other features such as locking the exposure and adjusting the brightness and contrast of the image.

You can enable the magnifier feature as follows:

  • Settings > General > Accessibility > Magnifier
  • Toggle on Magnifier

Now, when you want to bring up the Magnifier app, simply triple-click on the Home button.

How to activate the Flashlight feature

The camera's flash on your iPhone can be used as a flashlight.

Access the flashlight as follows:

  • Swipe up from the bottom edge of your screen to open Control Center
  • Tap the flashlight icon that appears in the bottom-left corner of the panel

If you have an iPhone 6s or later, then you can go further and use 3D Touch to control the brightness of the flashlight. Press deeply on the flashlight and choose between the options.

AssistiveTouch floats a small menu on your display (which you can move about on the screen to wherever suits you) that allows you to carry out gestures such as pinching or multi-finger swipes with a single finger, offers quick access to a variety of functions, and even allows you to activate Siri without pressing the Home button.

There are three ways to activate AssistiveTouch:

  • Tap Settings > General > Accessibility > AssistiveTouch, then switch on AssistiveTouch
  • Tap Settings > General > Accessibility > Accessibility Shortcut and then activate AssistiveTouch
