Before you start
Do not begin with a broad reset. Check the following first so you can isolate the problem and avoid unnecessary data loss or reconfiguration.
- A force restart is not a factory reset
- Use a normal restart when the phone still responds
- If the battery may be empty, connect a safe charger
Critical diagnosis for this symptom
Button sequences vary between Face ID and Home-button models. A force restart does not erase stored data.
This is different from restoring factory settings.
Escalate with device, OS, error, and reproduction details when the issue persists after restart, controlled comparison, and update checks, or when physical damage, abnormal heat, account suspension, or carrier provisioning is suspected.
Understand the process
Safe step-by-step procedure
Work from the top and stop as soon as the issue is resolved. Read every confirmation screen before moving to a higher-impact action.
- 1For iPhone 8 and later, including Face ID models, quickly press and release volume up, then quickly press and release volume down.
- 2Hold the side button until the Apple logo appears. Continue holding if the power-off slider appears, then release at the logo.
- 3On iPhone 7 or 7 Plus, hold the side and volume-down buttons together until the Apple logo appears.
- 4On iPhone 6s and earlier, hold the Home and side or top buttons until the Apple logo appears.
- 5If it will not start, charge for about an hour and then continue with display, charging or service checks.
Actions to avoid
- Holding the volume buttons instead of pressing and releasing quickly
- Releasing the side button before the logo appears
- Confusing a force restart with erasing the device
Prevention and preparation
- Confirm the model in Settings or purchase records
- After recovery, check OS updates and free storage
Frequently asked questions
What if my screen looks different?
Labels and locations vary by OS, manufacturer, model and region. Use Settings search and check the manufacturer’s model-specific instructions.
What if I am unsure partway through?
Go back and confirm that no action has been committed. Do not proceed through an erase or account-change warning until you understand it.
What if the problem remains?
Test another connection or accessory where relevant, verify backups, then contact the manufacturer or carrier through official support.
