TL;DR: You can reset your iPhone 15 Pro without a computer by using the On-Device Erase feature located in the Settings app. This process securely wipes all data and prepares your device for resale or troubleshooting.
Before you begin, it is crucial to ensure you have a recent backup of your data. Go to Settings > [Your Name] > iCloud > iCloud Backup and tap Back Up Now. This ensures your photos, contacts, and apps are safe before the wipe. Additionally, sign out of iCloud and Find My iPhone to avoid Activation Lock issues on the next device.
Prepare Your Device
First, connect your iPhone to a stable Wi-Fi network. A strong internet connection is vital for downloading the latest iOS software during the reset process. If your battery is below 50%, plug in your charger. The reset process consumes significant power, and an interruption could corrupt the operating system.
Step-by-Step Reset Instructions
Open the Settings app on your iPhone 15 Pro. Scroll down and tap on General. This menu contains all core system configurations. Next, scroll to the very bottom of the General menu and select Transfer or Reset iPhone.
Tap on Erase All Content and Settings. This option is the modern replacement for the older “Reset” menu and is specifically designed for on-device erasure. The system will ask you to enter your passcode and Apple ID password to confirm your identity. This security step prevents unauthorized erasures if your phone is stolen.
Read the on-screen warnings carefully. They explain that all media, data, and settings will be removed. Once you understand the implications, tap Continue. If you have an eSIM, you may be asked whether to keep or delete it. Choose Delete eSIM if you plan to sell the device or Keep eSIM if you are just troubleshooting.
Finally, confirm the action by tapping Erase iPhone again. Your screen will go black, and the Apple logo will appear. This process may take several minutes. Do not turn off your device during this time. The phone will reboot and eventually display the “Hello” setup screen, indicating a successful factory reset.
Important Tips
Ensure you remove the SIM card if you are selling the phone, as on-device deletion of eSIMs does not always remove physical SIMs. Also, unpair your Apple Watch before resetting if you use one, to save a backup automatically. Finally, check that your iCloud account is active to re-enable Find My iPhone on your new setup.
