Meta Description:

iOS 18 is packed with useful hidden features most iPhone users haven’t discovered yet. From app locks to offline Siri, here are 7 iOS 18 tricks you’ll want to try today.
Apple’s iOS 18 update is officially here, and with it comes a bunch of cool changes. Sure, the redesigned Control Center and improved Siri are getting all the attention but what about the hidden gems? You know, the little features tucked away in settings that can actually make a big difference?
If you’ve already updated your iPhone, here are 7 hidden iPhone features in iOS 18 that are super useful but easy to miss.

1. Lock Individual Apps with Face ID:

Ever wish you could put a lock on certain apps? now you can with iOS 18!
Apple finally added the ability to lock individual apps using Face ID or your passcode, so even if someone has your phone, they can’t open apps like Messages, Photos, or WhatsApp without your permission.

How to set it up:

  • Go to Settings > Privacy & Security > App Lock
  • Choose the app you want to lock
  • Turn on Require Face ID
It’s simple, it adds an extra layer of privacy.

2. More Battery Health Info Than Ever:

Apple used to only show your battery’s maximum capacity. But in iOS 18, you get way more details.
Now, you can see your battery cycle count, temperature, and charging history. It’s great if you’re trying to figure out why your battery drains fast or when it’s time for a replacement.

Find it here:

Settings > Battery > Battery Health & Charging


3. Use “Back Tap” for Quick Shortcuts:

If you’ve never used Back Tap, now’s the time. This feature lets you double or triple tap the back of your iPhone to perform actions like:
  • Taking a screenshot
  • Opening the flashlight
  • Running a shortcut
  • Launching an app
And iOS 18 makes it smoother and more responsive than before.

To turn it on:

Settings > Accessibility > Touch > Back Tap
It works even with a phone case!

4. Custom Vibration Alerts for Contacts:

Here’s a fun one: You can now create custom vibration patterns for specific contacts. So if your phone is on silent, you can still “feel” who’s calling or texting.

How to do it:

  • Open the Contacts app
  • Tap on a contact
  • Hit Edit > Ringtone > Vibration
  • Choose or create your own pattern
It’s a small detail that makes a big difference.

5. Siri Works Without Internet Now:

One of the best hidden updates in iOS 18 is that Siri now works offline for simple tasks.
Even when you’re not connected to Wi-Fi or data, you can still ask Siri to:
  • Set alarms and timers
  • Open apps
  • Control settings like Wi-Fi or Bluetooth
  • Adjust brightness or volume
It’s faster, more private, and super handy when you’re out of service.

6. Lock Hidden & Recently Deleted Photos:

In iOS 18, your Hidden and Recently Deleted photo albums are finally secure. You can now lock them using Face ID or your passcode, something users have wanted for years.

How to enable it:

Settings > Photos > Use Face ID
No more worrying about someone sneaking into private albums.

7. Smarter Voice Dictation (With Punctuation!):

Dictation got a serious upgrade in iOS 18. Now when you speak into your iPhone, it automatically adds punctuation, commas, periods, and question marks.
It’s perfect for sending messages or jotting down notes without typing, and it actually makes sense now.

Final Thoughts:

It’s easy to get excited about the big updates in iOS 18 but these hidden iPhone features are just as exciting (and honestly, more useful day-to-day).
Whether you’re locking apps, checking battery health, or asking Siri for help offline, these tools can really improve how you use your phone.
So if you haven’t updated yet, head to Settings > General > Software Update and give iOS 18 a try. You might be surprised by how much your iPhone can do now.
