10 Hidden iPhone Features Apple Doesn't Advertise

Every September, Apple gets on stage and tells the world what's new on iPhone. The keynote covers the new chip, the new camera, maybe a fresh AI demo. But the iPhone has dozens of hidden iPhone features that Apple barely mentions, some buried in support documents, others tucked behind menus most people never open. After spending time inside iOS 26 and digging through Apple's own pages, here are ten that genuinely change how I use my phone.

Use AirPods as a wireless microphone for video

The built-in mic on your iPhone is fine for a phone call. It is not fine for a video you actually want to sound good. With iOS 26, you can pair AirPods with the H2 chip and use them as a wireless lapel mic without buying any extra hardware.

You'll need AirPods 4, AirPods Pro 2, AirPods Pro 3, or AirPods Max 2. Open the camera app, switch to video, pull down Control Centre, and tap Camera Controls. Under Audio and Video, pick your AirPods as the input.

Mic Mode has four settings. Voice Isolation is the one I'd reach for in a noisy room. It's the same processing Apple uses on phone calls, and it does a good job of cutting background noise.

One caveat: this feature isn't available in every country, so check Apple's regional support pages if it doesn't show up.

Set a custom alarm snooze duration in iOS 26

Every iPhone alarm since 2007 has snoozed for exactly 9 minutes. The reason has nothing to do with Apple. In 1956, GE Telechron released the first mass-market snooze alarm, and its gear mechanism couldn't extend cleanly to 10 minutes, so engineers settled on 9.

Almost 70 years later, that decision was still inside your iPhone. iOS 26 finally lets you change it.

Open the Clock app, tap any alarm, make sure snooze is toggled on, then tap Snooze Duration. You can pick anything from 1 to 15 minutes.

One thing to know: the setting is per alarm, not universal. If you've got a weekday alarm and a weekend alarm, you'll need to set the duration on each one.

Adjust your iPhone flashlight beam width

The flashlight has been in iOS since 2013, but Apple only introduced an adjustable beam in iOS 18. Open Control Centre, tap the flashlight icon, and the Dynamic Island expands into a panel with a slider.

Drag it vertically to change brightness. On Pro iPhones, drag horizontally to widen or narrow the beam.

The beam-width control needs Apple's Adaptive True Tone Flash, the 3x3 grid of nine LEDs that's been in Pro iPhones since the iPhone 14 Pro. Regular iPhones use a simpler dual-LED flash and only get brightness control, not beam shaping.

T9 dialling on the iPhone keypad

You can dial someone by typing their name on the number pad, the same way you did on a Nokia 3310. It's called T9 dialling, and Apple quietly added it in iOS 18.

Open the Phone app, tap Keypad, then type the letters of a contact's name on the number keys. To call Mum, tap 6-8-6. The matching contact appears above the keypad. Tap their name and it dials.

There's no setting to turn it on. There's also no setting to turn it off. Apple just baked it in.

Turn the back of your iPhone into a button with Back Tap

In 2020, Apple turned the back of your iPhone into a button. They've barely mentioned it since.

Back Tap launched with iOS 14 and works on every iPhone from the iPhone 8 onwards. Go to Settings, Accessibility, Touch, and scroll down to Back Tap. You'll see Double Tap and Triple Tap, each with a list of actions to assign.

Most options are standard system controls: screenshot, Control Centre, lock screen, dark mode. The interesting one is Shortcut, which lets you trigger anything you've ever built in the Shortcuts app.

The reason most people have never set this up is that it's buried in Accessibility, which most people only open if they need an accessibility feature.

Set custom ringtones from any audio file in iOS 26

For most of the iPhone's history, setting a custom ringtone meant fighting with iTunes or learning GarageBand. iOS 26 added a third option that takes about thirty seconds.

Open the Files app, find an MP3 or M4A file that's 30 seconds or shorter, long-press it, tap Share, then scroll down to Use as Ringtone. The file then appears in Settings, Sounds and Haptics, ready to assign as your default ringtone, text tone, or to a specific contact.

The same trick works in Voice Memos. Open a recording, tap the three-dot menu, hit Share, and tap Use as Ringtone.

The only real limit is 30 seconds. If your audio is longer, trim it first in GarageBand or any audio editor on the App Store.

Trackpad mode on the iPhone keyboard

There's a keyboard gesture most iPhone users have never tried. Press and hold the space bar for half a second.

The letters fade away and the keyboard becomes a flat trackpad. Drag your finger across it and the cursor moves with you, landing exactly between the two letters you want instead of you tapping at the screen and missing.

For text selection, hold the space bar with one finger and tap the keyboard with a second finger. The cursor enters selection mode and dragging now highlights text.

Apple introduced this in iOS 12 in 2018. There's no setting, no tutorial, and no on-screen prompt, but it works on every modern iPhone. If you want a better typing experience overall, it pairs well with turning off iPhone predictive text.

Camera dirt alerts on iPhone 15 and later

At WWDC 2025, Apple ran through the headline iOS 26 features on stage, then flashed up a slide listing 36 more features they didn't have time for. Camera dirt alerts was one of them.

On iPhone 15 and later running iOS 26, the camera app can detect a smudged or dirty lens and pop up a warning before you take a photo or video. It's a small detail that has saved me from a few blurry shots.

If it doesn't fire, check it's enabled: Settings, Camera, then toggle on Lens Cleaning Hints. If you're serious about getting better photos out of the iPhone, my Pro RAW guide covers the settings worth changing.

Lock or hide apps behind Face ID

This should have been added years ago. Apple finally got there in iOS 18.

Long-press any app icon and the quick action menu now has a Require Face ID option. Tap it and the app is locked behind authentication, so someone holding your unlocked phone can't open it.

Tap Hide and Require Face ID instead and the app disappears entirely. It moves to a hidden folder at the bottom of the App Library, which is itself locked behind Face ID.

A handful of Apple system apps don't give you the option, but most apps do. The idea is that you can hand your phone over without worrying about anyone being nosy.

Long-press the back arrow to jump up a menu tree

Apple added this in iOS 14, almost six years ago, and barely anyone knows about it.

When you're deep inside a settings menu, say Settings, Apps, a specific app, then a sub-setting, you don't need to keep tapping back. Long-press the back arrow in the top-left and a vertical menu appears showing every screen above the one you're on. Tap any of them to jump straight there.

It works across Apple's own apps, including Files, Mail, Apple Music, and Notes. Plenty of third-party apps support it too, but that depends on the developer.

Why these hidden iPhone features matter more than the keynote slide

None of these features are secrets. They're all sitting inside iOS, sometimes for years, waiting to be found. Apple just doesn't put them on the keynote slide because they don't sell phones. But they're the features that actually change how you use the one you've already got.

FAQ

Can I use AirPods as a microphone with iOS 26 on any iPhone?

You'll need iOS 26 and AirPods with the H2 chip: AirPods 4, AirPods Pro 2, AirPods Pro 3, or AirPods Max 2. Availability also depends on region, so check Apple's support pages for your country.

Why did the iPhone snooze button stick at 9 minutes for so long?

The 9-minute standard goes back to the 1956 GE Telechron snooze alarm. Its mechanical gears couldn't cleanly extend by 10 minutes, so engineers picked 9. Apple kept that default until iOS 26 added a custom snooze duration setting.

Does Back Tap work on older iPhones?

Back Tap works on any iPhone from the iPhone 8 onwards running iOS 14 or later. You'll find it under Settings, Accessibility, Touch, Back Tap.
