YOUR iPhone's Side Button isn't just for locking the screen – it's hiding at least four very handy tricks. With the right combination of settings and "clicks", you can make it do some surprising things, including helping you dodge car sickness. The first three tricks on our list all relate to a feature called the Accessibility Shortcut.

This lets you assign different functions to the Side Button, all activated with a quick "triple click". There are dozens of options, but there are particularly handy. First, you'll want to go to Settings > Accessibility > Accessibility Shortcut. You'll see a long list of features that you can add to the Side Button.

It'll still work for locking your iPhone, but if you triple-click it then it'll activate the feature of your choice. And if you choose multiple options, triple-clicking will launch a pop-up menu with your selections – letting you tap the one you want at the time.

It's not just for sleep either: you can have Background Sounds playing over the top of podcasts and other types of media too. Second is Vehicle Motion Cues, which is built to combat the nausea from using your iPhone while in a moving car. "If you experience discomfort when you use iPhone while riding as a passenger in a car or other on-road vehicle, you can turn on Vehicle Motion Cues – onscreen cues that may help reduce motion sickness," Apple explains.
