15 iPhone tricks you really need to know about

An iPhone doesn't come cheap, so it's worth exploring all of its key features – along with some lesser-known tips and tricks that many people might not be aware of.

You might not know, for example, that your trusty iPhone can function as a measuring tape using the power of augmented reality (AR). Plus, you can use Apple Back Tap to take a screenshot just by knocking on the rear of your mobile.

Below, we've pulled together some handy tips so you can get more from your iPhone, including favourites from Which? members.

1. Use your iPhone to measure nearby objects

At a glance: the Measure app (available on iOS 12 and above) uses your mobile's rear camera to measure real-world objects.

Your phone can automatically detect the dimensions of a rectangular object, or you can manually tap the screen to set start and end points.

To try it yourself, open the Measure app and point the iPhone camera at a nearby object. Align the on-screen dot at the centre of your screen with the point where you want to start measuring, then tap the + symbol. Slowly move your phone to the end point to see the measured length.

On 'Pro' iPhones equipped with a LiDAR Scanner, you can measure the height and straight edges of furniture and countertops. These same models also support Ruler view, which means you move the iPhone closer to the measurement line until it transforms into a ruler.

2. Translate text using the Camera app

At a glance: you can make sense of text in an unfamiliar language without installing an app.

To try this, simply open the Camera app and hold your phone still while it scans the text.

Once your mobile recognises the text, you'll see yellow lines circle the area on screen. In the bottom right corner, tap the Scan symbol – this will isolate the text and magnify it as a still image. Finally, click Translate in the bottom left corner of your display to see the results.

If you have a picture in your image library that features text you'd like translated, simply tap the Scan symbol in the bottom-right corner.

3. Customise your iPhone with widgets

At a glance: see information at a glance without opening any apps.

These handy additions to your Home and Lock screens let you personalise your experience. You could have a widget that displays your to-do list, for example, or a widget that lets you scan the nearby area for restaurants at the tap of a button.

To add widgets to your Home Screen, tap and hold on the area until your apps start shaking. Select Edit > Add Widget, then choose a widget and your preferred size.

If you're shopping for a new phone, make sure you consult our expert mobile phone reviews to see which models are Best Buys.

4. Use your iPhone with one hand

At a glance: with Reachability enabled, content on the top half of your screen is dropped lower so your thumb can reach it.

If you own an iPhone with a large display, you might struggle to reach the top of the screen with one hand. If so, we recommend trying Apple's accessibility feature.

To activate Reachability, head to Settings > Accessibility > Touch, then enable Reachability.

• If your iPhone has Face ID, you just need to swipe down on the bottom edge of the screen to activate the feature 
• On models with a Home button, double-tap the Home button to use Reachability. 

You can return to a full-screen experience any time by tapping the upper half of the screen.

5. Explore the pre-installed accessibility features

At a glance: These are designed to support your vision, hearing and learning needs, and can be accessed at any time.

Every iPhone comes with pre-installed accessibility tools aiming to make the gadget easier to use. The full list of accessibility features on iPhone is listed on the Apple website. We've picked out three of them here:

• Adjust text size – go to Settings > Accessibility > Display & Text Size. From this screen, you can adjust a selection of visual elements, including Bold Text, Larger Text, Button Shapes (underlines text that you can tap), Increase Contract (improves legibility) and Colour Filters.
• Magnify your entire screen – head to Settings > Accessibility > Zoom, then turn on Zoom when you're happy with the settings. To use it, double-tap your screen with three fingers. You can then adjust the magnification level, move the Zoom lens in Window Zoom or pan to another area in Full Screen Zoom.
• Have your iPhone read text aloud – go to Settings > Accessibility > Spoken Content. From this page, you can adjust the voice and dialect, as well as the speaking rate and specific pronunciations. With Spoken Content enabled, you can say 'Siri, speak screen'. Alternatively, you can tap on a block of text and then select Speak. If you swipe down with two fingers from the top of the display, you can hear the entire screen.

6. Use Back Tap to take a screenshot

At a glance: set up your iPhone so that a tap on the back takes a screenshot.

You might find this quicker compared to the 'normal' way (pressing the side and volume up buttons at the same time).

Head to Settings > Accessibility > Touch and select Back Tap. Now, you can choose Double Tap or Triple Tap and then a related action. You can assign taps to the screenshot function, for example, or set up your phone so that three taps activates the Magnifier feature.

7. Find your lost Apple products

At a glance: the Find My app can pinpoint your other iOS devices.

Load up the Find My service on your iPhone and you spot your other devices on a map, even if they're offline. The app can monitor a whole host of Apple goodies: iPhone, iPad, iPod touch, Apple Watch, Mac, AirPods and AirTag.

Using the app, you can play a sound through your missing device, helping you or others nearby to locate it. If you lost your AirPods, for example, you'd need to follow these steps on your iPhone:

1. Open the Find My app.
2. Under the Devices heading, tap your AirPods.
3. Choose between Play Sound and Directions.
4. Select Notify When Found or Mark As Lost (optional).

Our guide on what to do if your phone gets stolen explains how to recover your device – and important actions to work through before it goes missing.

8. Pause notifications so you can focus on work

At a glance: if you need a break from your iPhone, creating a Focus will minimise distractions.

Your iPhone has a setting called Focus that temporarily silences all notifications, or allows only specific alerts that you choose. For instance, if you're trying to stay productive during the day, you can create a profile that silences notifications from games but still allows updates for emails.

To set up a custom profile in Focus, try this:

1. Swipe down from the top-right corner of your screen.
2. Long-press the Focus button to open Focus profiles and choose New Focus.
3. Follow the on-screen instructions to decide which apps you want to pause notifications for.

This feature works on Mac, too, and you can use the same Focus settings on all your Apple devices where you’re signed in to the same Account.

9. Use two-factor authentication to protect your data

At a glance: Add an extra layer of security to your Apple account.

Two-factor authentication (2FA) helps keep your Apple account secure. In other words, it ensures your iCloud data (including photos), emails, and Find My device information aren’t accessed without your permission.

Even if someone knows your Apple account password and tries to log in from their own device, they won’t be able to access your information without entering the unique verification code sent to your iPhone – which only you can see.

To set up 2FA from your iPhone, head to Settings > [Your name] > Sign-In & Security. Tap Turn On Two-Factor Authentication. Select Continue and follow the on-screen instructions.

10. Use Low Data Mode to limit your usage

At a glance: you can use this feature to avoid going over your data allowance.

With Low Data Mode enabled, you can quickly restrict background network use on your iPhone. You might find this feature handy if you're on a limited data plan, travelling through an area with poor network coverage or trying to conserve battery life.

To try it, go to Settings and tap Mobile Data. Choose Mobile Data Options > Data Mode.

Apple's website notes that Low Data Mode might reduce the quality of streaming content. Plus, it'll turn off automatic downloads, pause updates and disable high-quality streaming if you're using Apple Music.

If you want to turn off data entirely, you can use Airplane Mode – tap the Plane icon in Control Centre.
