To force restart an unresponsive iPhone 15 Pro Max, quickly press Volume Up, quickly press Volume Down, then hold the Side button until the Apple logo appears. A force restart does not intentionally erase personal data; erasing the phone is a separate procedure.

Which reset method should you use on an iPhone 15 Pro Max?

“Hard reset iPhone 15 Pro Max” can describe several different actions, so choose the method based on what you need:

  • Force restart: Use this when the screen is frozen, black, or not responding. It restarts iOS without intentionally deleting personal data.
  • Reset settings: Use this for certain configuration problems when you can still open Settings. In Settings, select General, Transfer or Reset iPhone, and Reset. You can reset options such as network settings without erasing all personal content.
  • Erase all content and settings: Use this when preparing the iPhone for another person or when troubleshooting requires a clean start. This removes personal information, apps, and settings from the device.

Back up important information before resetting settings or erasing the iPhone. A force restart normally does not require a backup, but unsaved work in an open app could be lost when the app closes.

How do you force restart an iPhone 15 Pro Max?

Use the following official button sequence to force restart iPhone 15 Pro Max when it is frozen or unresponsive:

  1. Quickly press and release the Volume Up button.
  2. Quickly press and release the Volume Down button.
  3. Press and hold the Side button.
  4. Keep holding the Side button if the power-off slider appears.
  5. Release the Side button when the Apple logo appears.

The first two button presses must be separate, quick presses. Do not hold either volume button. The final Side-button press is the only button press that you hold.

This procedure may also be described as a “hard restart iPhone 15 Pro Max” or “iPhone 15 Pro Max hard reset.” In this guide, those search phrases mean a force restart, not a factory erase. If you were asking how to hard restart iPhone 15 Pro Max without deleting personal data, use the button sequence above.

How do you erase an iPhone 15 Pro Max in Settings?

Erasing an iPhone 15 Pro Max removes its personal content and returns its settings to their initial state. Do not use this procedure when you only need to restart a frozen screen.

  1. Connect the iPhone to power if its battery is low.
  2. Back up information you want to keep. You can use iCloud or a connected Mac or Windows PC.
  3. Open Settings and select General.
  4. Select Transfer or Reset iPhone.
  5. Select Erase All Content and Settings.
  6. Review the information that will be removed, then select Continue.
  7. Enter the iPhone passcode when requested.
  8. Enter the Apple Account password if requested. This allows the device to sign out and turn off Activation Lock as part of the authorized erase.
  9. When asked about the eSIM, choose whether to keep it or erase it. Keep it if you are erasing the phone for your own continued use. Remove it when transferring the phone, unless your carrier has given different instructions.
  10. Confirm the erase and allow the iPhone to complete the process without disconnecting it from power.

If you remove an eSIM that you still need, contact the mobile carrier for help restoring cellular service. An erased iPhone displays its setup screen when the process finishes.

How can you reset an iPhone 15 Pro Max without access to Settings?

Recovery mode lets a connected computer reinstall iOS when the iPhone 15 Pro Max cannot start normally or Settings cannot be opened. Restoring through recovery mode erases the device, so use a backup later to recover available data.

  1. On a Mac, open Finder. On a Windows PC, open the Apple Devices app; use iTunes only on a computer where that is the supported Apple device-management program.
  2. Connect the iPhone 15 Pro Max to the computer with a working USB cable.
  3. Quickly press and release Volume Up.
  4. Quickly press and release Volume Down.
  5. Press and hold the Side button. Continue holding it after the Apple logo appears.
  6. Release the Side button when the recovery-mode screen showing a cable and computer appears.
  7. Select the iPhone on the computer.
  8. Choose Restore when offered the choice between Update and Restore. Follow the computer’s prompts to download and install the current compatible iOS software.
  9. Keep the iPhone connected until the restoration completes and the setup screen appears.

Recovery mode does not bypass a passcode, Apple Account credentials, or Activation Lock. After restoration, the iPhone may require the Apple Account previously associated with it.

What should you do if the iPhone 15 Pro Max reset does not work?

If the iPhone 15 Pro Max remains frozen, repeat the force-restart sequence carefully. The most common problem is pressing both volume buttons together, holding a volume button, or releasing the Side button before the Apple logo appears.

  • If nothing appears, connect the iPhone to a known-working charger and cable, then try the force restart again.
  • If recovery mode does not appear, keep holding the Side button beyond the Apple logo until the cable-and-computer screen is displayed.
  • If the computer does not detect the iPhone, reconnect the cable, try another working USB port or compatible cable, and confirm that Finder, Apple Devices, or iTunes is current.
  • If restoration stops, check the computer’s internet connection and available storage, restart the computer, reconnect the iPhone, and enter recovery mode again.
  • If buttons are damaged, the iPhone will not charge, or repeated official procedures fail, contact Apple Support or an Apple-authorized service provider. Do not use software claiming to bypass account security.

What should you do before giving away or trading in an iPhone 15 Pro Max?

Before transferring an iPhone 15 Pro Max, protect your information and make sure the next owner will not encounter Activation Lock.

  1. Back up the data you want to keep.
  2. If an Apple Watch is paired, unpair it using Apple’s normal account process.
  3. Open Settings, select your name, and sign out of the Apple Account. Enter the account password when requested.
  4. Erase all content and settings using Settings, General, Transfer or Reset iPhone.
  5. Choose to erase the eSIM when the phone is leaving your possession, unless your carrier instructs you otherwise.
  6. Remove the physical SIM card if one is installed.
  7. Confirm that the phone reaches the initial setup screen and no longer contains your photos, messages, apps, or accounts.
  8. Check your trusted-device list from another signed-in Apple device or through your Apple Account and remove the transferred iPhone if it remains listed.

Do not give another person your passcode or Apple Account password. If Activation Lock remains enabled, resolve it through your own Apple Account or Apple Support rather than attempting a bypass.
