Is your iPhone 12 refusing to turn off? This common issue can be frustrating for users. To turn off an unresponsive iPhone 12, press and quickly release the volume up button, then the volume down button, and finally hold the side button until the Apple logo appears. This process, known as a force restart, often resolves the problem.
If the force restart doesn’t work, there may be a software glitch or a hardware malfunction. Some users report success by letting the battery drain completely before recharging. Others find that updating the iOS software can fix the issue.
For persistent problems, contacting Apple Support or visiting an Apple Store might be necessary. They can diagnose and repair any hardware issues that prevent the iPhone 12 from turning off properly.

Understanding the iPhone 12 Hardware
The iPhone 12’s hardware design marks a significant evolution in Apple’s smartphone technology. Its button layout and functionality play a crucial role in device operation and troubleshooting.
Side Button and Volume Buttons
The iPhone 12 features three main external buttons: the side button and two volume buttons. The side button, located on the right edge, serves multiple functions. It powers the device on and off, activates Siri, and enables Apple Pay.
The volume buttons sit on the left side of the phone. These buttons adjust audio levels and can be used in combination with the side button for various tasks. For instance, pressing and quickly releasing the volume up button, followed by the volume down button, and then holding the side button forces a restart of the device.
This button configuration allows users to perform essential actions without accessing the touchscreen. It proves especially useful when the iPhone 12 becomes unresponsive or fails to turn off normally.
Sleep/Wake Button Evolution
The sleep/wake button on the iPhone 12 has undergone significant changes from earlier models. Previously known as the power button, it moved from the top of the device to the side with the iPhone 6.
On the iPhone 12, this button gained additional capabilities. It now serves as the “side button,” incorporating functions previously handled by the home button on older models. This change accommodates the full-screen design of newer iPhones.
The side button on the iPhone 12 can wake the device, put it to sleep, activate Siri, and trigger emergency features. Its placement and multi-functionality represent Apple’s focus on streamlining user interactions while expanding device capabilities.
Troubleshooting Steps to Turn Off iPhone 12
If your iPhone 12 won’t turn off, several methods can help resolve this issue. These techniques range from basic force restarts to using built-in accessibility features.
Force Restart Procedure
The force restart method is often the most effective way to turn off an unresponsive iPhone 12. This process doesn’t erase any data and can fix many software glitches.
- Press and quickly release the volume up button.
- Press and quickly release the volume down button.
- Press and hold the side button.
- Keep holding until the Apple logo appears.
This sequence may take 10-30 seconds. Once the Apple logo shows, release the side button. The iPhone will restart, potentially resolving the issue.
Using AssistiveTouch to Turn Off iPhone 12
AssistiveTouch provides an on-screen menu for various functions, including powering off the device. This method is useful if the physical buttons are unresponsive.
To enable AssistiveTouch:
- Go to Settings > Accessibility > Touch > AssistiveTouch
- Toggle AssistiveTouch on
To turn off the iPhone using AssistiveTouch:
- Tap the AssistiveTouch button
- Select Device > More > Restart
This virtual method bypasses physical button issues and can often shut down a problematic device.
Utilizing Emergency SOS
Emergency SOS can force an iPhone 12 to turn off as a last resort. This feature is designed for emergencies but can help with unresponsive devices.
To use Emergency SOS:
- Press and hold the side button and either volume button
- Slide the Emergency SOS slider
This action will call emergency services and turn off the iPhone. Cancel the call immediately if not in an actual emergency. The device will power down, potentially resolving the issue upon restart.
Advanced Solutions and Preventive Measures
When an iPhone 12 won’t turn off, advanced solutions and expert assistance can help resolve persistent issues. These methods go beyond basic troubleshooting to address complex software problems or hardware malfunctions.
Software Update and Restoration
Updating iOS or restoring the iPhone 12 can fix stubborn software glitches. Connect the device to a computer with iTunes or Finder. Check for available iOS updates. If updates don’t solve the problem, consider a full restore.
Backup important data before restoring. Choose “Restore iPhone” in iTunes or Finder. This erases all content and installs the latest iOS version. After restoration, set up the iPhone as new or restore from a backup.
If the iPhone still won’t turn off, try Recovery Mode. Connect to a computer and force restart the device. Hold the side button until the Recovery Mode screen appears. Update or restore the iPhone through iTunes or Finder.
Contacting Apple Support
For unresolved issues, Apple Support offers expert assistance. Visit apple.com/support or use the Apple Support app to schedule an appointment. Explain the problem in detail to the support representative.
Apple Support may suggest additional troubleshooting steps. They can run remote diagnostics to identify hardware issues. If necessary, they’ll arrange repair or replacement options.
For in-person help, visit an Apple Store or Authorized Service Provider. Bring proof of purchase and backup your data beforehand. Technicians can perform hands-on diagnostics and repairs.
Face ID issues may require specialized support. Apple’s face recognition system is complex. Only authorized technicians should attempt repairs involving Face ID components.
