How to fix iPhone vibrates randomly
After understanding the potential reasons, you can now explore the most suitable solutions in this guide to efficiently solve your problem. Before that, you can check your charging cable or switch to another reliable one to determine if the issue is caused by hardware.
Solution 1. Force restart your iPhone
Force restarting your iPhone can be a basic way to solve lots of issues on your device.
For iPhone 8 Plus/8/X or later: Press and release the Volume Up button > Press and release the Volume Down button > Press and hold the side button until the Apple logo appears.
For iPhone 7 Plus or 7: Press and hold the Sleep/Wake and Volume Down buttons simultaneously until the Apple logo appears.
For iPhone 6 or earlier: Press and hold the Home button and Sleep/Wake button at the same time until the Apple logo is displayed on your screen.
Solution 2. Change your vibration settings
Sometimes, the issue may be caused by the vibration settings. You can change them to solve the problem, but please note that this will stop all vibrations, and your iPhone will not vibrate for texts or phone calls.
Here's how to do: Go to Settings app on your iPhone > Click Sounds or Sounds & Haptics > At the top of the next screen, you'll find two options for vibrations. Turn off both of them to stop the vibration.
In some situations, the issue may relate to email notifications, you can scroll down the page to find and click on New Mail option and set it to None.
Solution 3. Check the notification settings
Occasionally, the causes behind your iPhone's random vibrations can be linked to instant messaging apps and the Mail app, so be sure to check the notification settings of these apps.
Launch Settings app > Go to Notifications and find the targeted apps from the list. You can tap and check their settings to see if Allow Notifications is on. If notifications are on, try to change them or add alerts.
Solution 4. Check the accessibility settings
Verify whether the accessibility feature Touch Accommodations is active on your iPhone. Turning off this feature could potentially solve the unexpected vibrations once and for all. (Go to Settings > Accessibility > Touch > Touch Accommodations.)
Solution 5. Delete the third-party apps
If you've recently installed a new app on your iPhone and have noticed the “iPhone randomly vibrates no notification” issue occurring afterward, it's possible that the app is causing the problem. Then you can try to delete the suspicious apps to solve the problem.
Solution 6. Let the battery fully drain out
If other ways don’t work, you can let the vibration run until it drains your device's battery. Since vibration consumes more battery power than regular usage, your battery will deplete relatively quickly, and this should put a stop to the random vibration issue.
In this process, you can estimate the remaining battery life based on your iPhone's battery percentage display. After your battery is completely drained, you can recharge your iPhone, and you're unlikely to encounter the problem again.
Solution 7. Update the software
Random vibrations might be initiated by a glitch within an app or the iOS system. Go to the App Store to confirm that all your apps are up to date. If vibrations continue, updating to the latest iOS version might be the solution you need.
Go to Settings app > General > Software Update. If there is any software update option available, choose it and click Install or Download and Install to update your iOS to the latest version.
Solution 8. Reset all settings
Another option to consider is resetting all settings on your iPhone to address the issue. This won't delete any data or apps on your iPhone but will reset all system settings. Be prepared to reconfigure your preferences after performing this reset. (Go to Settings > General > Reset > Choose Reset All Settings.)
Solution 9. Factory reset your iPhone with a professional tool
