Fix a Frozen iPhone: Force Restart Steps

If your iPhone is frozen and unresponsive, a force restart is the first fix to try. This article explains exactly how to force restart any iPhone model, what to do if it doesn’t work, and how to avoid data loss.

What Is a Force Restart?

A force restart is a hardware-level reset that interrupts the iPhone’s normal shutdown sequence. It is different from a standard restart (swipe to power off) because it works even when the screen is black, the touchscreen is unresponsive, or an app has crashed. The force restart does not erase any data; it simply cuts power to the processor and reboots the system, clearing temporary memory and ending stuck processes.

Force Restart by iPhone Model

The button combination varies by model because of changes in the physical buttons and Face ID. Use the correct sequence for your device:

iPhone 8 or later (including iPhone SE 2nd/3rd gen): Press and quickly release the Volume Up button, then press and quickly release the Volume Down button. Next, press and hold the Side (power) button until the Apple logo appears (about 10–15 seconds). Release the side button.
iPhone 7 and 7 Plus: Press and hold both the Side (power) button and the Volume Down button simultaneously. Keep holding until the Apple logo appears, then release both.
iPhone 6s and earlier, including iPhone SE 1st gen: Press and hold both the Home button and the Side (or top) power button together. Hold until the Apple logo appears, then release.

If your iPhone has a physical Home button, use the Home+Power combo. If it has Face ID, use the volume sequence. If you are unsure, check the model number in Settings > General > About.

Why Does the Force Restart Work?

When an iPhone freezes, the operating system (iOS) may be stuck in a loop or the processor may be overwhelmed by a runaway app. A force restart bypasses the normal software shutdown and directly resets the hardware. The iPhone’s boot ROM (read-only memory) detects the button sequence and forces a clean boot. This clears the volatile memory (RAM) and reloads iOS from scratch, which resolves most temporary software glitches.

What to Do If the Force Restart Doesn’t Work

If the Apple logo does not appear after 20–30 seconds of holding, you may have a deeper issue. Try these steps in order:

Check the battery. Plug the iPhone into a charger and wait 5–10 minutes. A completely drained battery may show no response. If the charging screen appears, let it charge to at least 10% before retrying the force restart.
Check the charging cable and port. A damaged cable or a blocked Lightning/USB-C port can prevent charging. Try a different cable and wall adapter, and gently clean the port with a soft, dry brush (do not use liquids or metal objects).
Connect to a computer. If the iPhone still won’t respond, connect it to a computer with the latest version of Finder (macOS Catalina or later) or iTunes (Windows or older macOS). If the computer recognizes the device, you may see a “Recovery Mode” or “Update” prompt. Choose Update to reinstall iOS without erasing data. If that fails, you may need to choose Restore, which erases the device.
Enter Recovery Mode manually. If the computer does not detect the iPhone automatically, you can force it into Recovery Mode using the same button sequence as a force restart, but keep holding the buttons until the “Connect to computer” screen appears. Then use Finder/iTunes to update or restore.

If none of these work, the issue may be hardware-related (e.g., a faulty battery, logic board, or display). Contact Apple Support or an authorized service provider for diagnosis.

Common Misconceptions and Mistakes

“Force restart erases my data.” This is false. A force restart never deletes photos, messages, or apps. It only clears temporary system memory. Data loss only occurs if you choose “Restore” in Recovery Mode or DFU mode.
“I need to hold the buttons longer.” Holding too long (over 30 seconds) may trigger Recovery Mode or DFU mode, which shows a different screen. If you see a computer icon, you are in Recovery Mode; release the buttons and follow the on-screen prompts.
“The volume buttons must be held, not tapped.” For iPhone 8 and later, you must press and release the volume buttons quickly—do not hold them. Holding them may not trigger the sequence.
“Force restart fixes all freezes.” It fixes most software-related freezes, but not hardware failures. If the iPhone freezes repeatedly even after force restarting, there may be a persistent software bug (update iOS) or a failing component.

When to Use a Standard Restart vs. Force Restart

Use a standard restart (swipe to power off, then slide to power on) when the screen is responsive and you just want to clear memory or apply a minor update. Use a force restart only when the screen is unresponsive, the touchscreen doesn’t respond, or the device is stuck on a black screen or the Apple logo. A force restart is more aggressive but safe; it is the recommended first step for any unresponsive iPhone.

Frequently Asked Questions

Will a force restart delete my photos or contacts?

No. A force restart only clears temporary memory (RAM) and reboots the operating system. All your data, including photos, contacts, and messages, stays on the internal storage. The only way to lose data is to erase the device via Settings or Recovery Mode.

How often can I force restart my iPhone?

You can force restart as often as needed. There is no limit, and it does not damage the hardware. However, if you find yourself force restarting frequently (every day or multiple times a week), it indicates an underlying software or hardware problem that should be addressed—try updating iOS or contacting support.

What is the difference between Recovery Mode and DFU mode?

Recovery Mode shows a “Connect to computer” screen and allows you to update or restore iOS. DFU (Device Firmware Update) mode is a deeper state where the screen is black and the device can communicate with a computer without loading the bootloader. DFU mode is rarely needed and is used for major firmware issues. A force restart does not enter either mode; it simply reboots normally.

My iPhone is frozen but the screen is black—how do I know it’s charging?

Connect it to a charger and wait a few minutes. If the battery is completely drained, you may see a low-battery icon (red battery with a lightning bolt) or a black screen with a charging indicator. If nothing appears after 15 minutes, try a different cable and adapter, and check the port for debris.

Can I force restart an iPhone with a broken screen?

Yes, as long as the buttons work. The force restart sequence uses only the physical buttons, so a broken display does not prevent the restart. If the screen is completely black but the phone is on, you may still be able to force restart and later back up the device via a computer.

Why does my iPhone keep freezing after a force restart?

Repeated freezing usually points to a software bug (check for an iOS update), insufficient storage (free up space), or a failing app (delete recently installed apps). If the problem persists across updates and resets, it may be a hardware issue—contact Apple Support for diagnostic testing.
