iPhone randomly vibrates? Here's how you can try to fix it

What's with these random vibrations?

Published onNovember 11, 2023

If your iPhone vibrates, your first thought might be that you got a notification. What if you find nothing when you check it, though? Was it a phantom vibration? While possible, there are more chances it’s something with the device. Today, we’ll show you what you can do if your iPhone randomly vibrates for no apparent reason.


If your iPhone randomly vibrates, it's most likely due to the way you've configured your settings. It could also be a bug, though, or a faulty cable.


Why does my iPhone vibrate randomly?

There are multiple reasons why your iPhone may vibrate randomly. Most times, the reason might be that you have visual notifications turned off, but haptic notifications continue to operate as they should.

Of course, this is only one possible scenario. You could also be running into software bugs, whether they are in the system or third-party apps. You might also want to take a look at your cable, as it might be faulty.

Six  ways to fix your iPhone that’s vibrating randomly

Restart the phone

The good ol’ restart seems to work wonders whenever something’s not working with any tech gadget. Simply rebooting an iPhone is known to fix random vibrations, so give it a try. Here’s a guide on how to restart an iPhone, if you don’t already know the steps.

Make sure visual notifications are enabled

There is also a chance you turned off visual notifications. When you do this, the phone will play the notification sound and/or vibrate, but you will see no actual notification on your screen.

  1. Launch the Settings app.
  2. Go into Notifications.
  3. Scroll down to the Notification Style section. There will be a list of your apps here.
  4. You can go through each, or find the ones you suspect to be the culprits. Tap on your app of choice.
  5. Make sure Allow Notifications is toggled on.
  6. Also, go to the Alerts section and ensure you’ve checkmarked where you want visual notifications to appear. The options are Lock Screen, Notification Center, and Banners. If these aren’t selected, you won’t see notifications in the associated areas.

Update your apps and iOS version

If this is not the issue, we can assume there’s a bug in one of your third-party apps, or even the iOS software. Apple and app developers often push out updates to squash bugs in the code. Try updating everything to the latest version. Here are our guides on how to update iPhone apps and how to update iOS.

Reset all settings

If your iPhone randomly vibrates even after trying all the tips mentioned, we should move on to slightly more drastic measures. You can factory reset only your settings, without having to wipe the phone.

  1. Launch the Settings app.
  2. Go into General.
  3. Select Transfer or Reset iPhone.
  4. Tap on Reset.
  5. Select Reset All Settings.
  6. Enter your PIN, then confirm by hitting Reset All Settings again.
  7. Confirm once again by hitting Reset All Settings.

Is it a faulty cable?

Depending on your settings, your iPhone can vibrate whenever you plug it in. The thing is, a faulty cable can stop charging your cable sporadically. When it starts charging again, the iPhone will vibrate.

Analyze your cable. Look for any obvious signs of damage, such as rips, bends, rusty connections, etc. You can also try another cable if you have one lying around. Or try using your cable with another iPhone, to see if it causes the same issue.

If you determine the cable is the problem, we have a list of the best iPhone 15 cables. Those with an older iPhone will need a Lightning cable.

Turn off haptic vibration

If you’ve tried everything and can’t figure out what’s happening, you may need to adapt. You can turn off vibrations altogether! This isn’t really a proper solution, but it will stop your iPhone from randomly vibrating.

  1. Launch the Settings app.
  2. Go into Sounds & Haptics.
  3. Under Ringtone and Alerts, hit Haptics.
  4. Select Never Play.

If none of these tips work, the issue might be more complex. The only other advice we can provide is to contact Apple Support or go to an Apple Store.
