Manually restart or power off an unresponsive iPhone
A force restart or full shut down can resolve a frozen or unresponsive iPhone using a physical button sequence, without needing to reach Settings at all.
How to open Force Restart & Shut Down
- On Face ID models, quickly press and release Volume Up, then Volume Down.
- Press and hold the Side button until the Apple logo appears.
- Release the button and wait for the device to fully restart.
- If it still won't respond, connect it to power and try again after 30 minutes.
What you should know
- Shut Down can also be triggered in Settings > General > Shut Down as a software-based alternative.
- Force restart button sequences differ by model, generally involving the volume and side buttons.
- A force restart does not erase any data; it simply power-cycles the device.
- Shutting down fully, then powering back on, can resolve issues a force restart alone doesn't fix.
Why it matters
When an iPhone freezes, becomes unresponsive to touch, or an app appears permanently stuck, a force restart is often the fastest and safest first troubleshooting step before considering anything more drastic like a reset or restore. Because the exact button combination varies across iPhone generations, from a single held button on older models to a specific press-and-release sequence on Face ID models, knowing the correct sequence for a specific device avoids fumbling during a stressful moment. It's a completely data-safe action, making it the natural starting point before escalating to Recovery Mode or DFU Mode.
Best practices
- Try a standard restart from Settings or the power-off slider first, reserving a force restart for when the device is truly unresponsive.
- Learn the specific button sequence for your iPhone model in advance, since it differs from other models.
- Escalate to Recovery Mode only if a force restart doesn't resolve the freeze or if the device won't turn on at all.
Common problems and fixes
- Not sure which button sequence applies to a specific iPhone.
- Face ID models use a quick press of volume up, then volume down, then a held press of the side button; models with a Home button typically hold Home and the side/top button together.
- The screen stays black even after a force restart.
- Plug the iPhone into power for at least 30 minutes in case the battery was fully depleted, then try again.
Tips and tricks
- If Settings is accessible, a standard Shut Down and manual power-on is a gentler equivalent worth trying first.
Frequently asked questions

No, it's a normal recovery action, though it shouldn't be needed frequently under normal circumstances.
