How To Reset An iPhone 15: Complete Reset and Restore Guide

Resetting an iPhone 15 is easy when you know the steps. First back up your data, then try a soft restart for simple glitches. If the phone is frozen, do a force restart. To clear everything, use Erase All Content and Settings or restore with a computer in recovery mode. Follow the steps below for safe, complete resets and details on when to use each method.

Tutorial – How To Reset An iPhone 15

These steps will walk you through backing up, restarting, force restarting, resetting network or settings, doing a factory erase, and restoring via a computer if needed. Pick the step that fits your problem, and follow the details to avoid data loss.

Step 1, Back up your iPhone before you reset.

Back up to iCloud by opening Settings, tapping your name, then iCloud, and choosing iCloud Backup, or back up to a Mac or PC using Finder or iTunes.
Backups protect your photos, messages, and app data so you can restore them after a reset. Always verify the backup finished before erasing the phone.

Step 2, Do a soft restart to fix minor issues.

Press and hold either volume button and the side button until the power-off slider appears, then slide to power off and turn the device back on.
A soft restart fixes many small glitches like apps crashing or slow performance without deleting anything.

Step 3, Force restart a frozen iPhone 15.

Quickly press and release Volume Up, then quickly press and release Volume Down, then press and hold the Side button until the Apple logo appears.
Use a force restart when the screen is unresponsive or the phone is stuck on a loading screen. This does not erase your data, it just forces the system to reboot.

Step 4, Reset Network Settings to fix Wi Fi or cellular problems.

Go to Settings, tap General, then Transfer or Reset iPhone, choose Reset, and select Reset Network Settings.
This removes saved Wi Fi passwords, paired Bluetooth devices, and VPN settings, but keeps your apps and files. You will need to re-enter Wi Fi passwords afterward.

Step 5, Reset All Settings to clear system settings without deleting data.

Open Settings, choose General, tap Transfer or Reset iPhone, then Reset, and select Reset All Settings.
This returns system settings like display, privacy, and keyboard back to defaults while preserving your apps, photos, and messages. It is useful when settings conflicts cause problems.

Step 6, Factory reset by erasing all content and settings.

In Settings go to General, Transfer or Reset iPhone, then Erase All Content and Settings, follow the prompts, and enter your passcode and Apple ID password if requested.
A factory reset deletes everything and returns the phone to its out-of-box state, so only do this after you back up. If Find My iPhone is enabled you will need your Apple ID password to complete the erase.

Step 7, Use recovery mode with a computer if the phone will not start.

Connect the iPhone 15 to a Mac or PC with a cable, open Finder or iTunes, then perform the force restart sequence but keep holding the Side button until the recovery mode screen appears and follow the computer prompts to Update or Restore.
Recovery mode lets the computer reinstall iOS when the device cannot boot normally, and you can choose Update first to try preserving data. If Update fails, use Restore, which will erase the device and install fresh software.

Step 8, Use DFU mode for a deep restore when nothing else works.

On a computer, connect the iPhone, quickly press Volume Up then Volume Down, then press and hold the Side button until the screen goes black; release and then press a specific button combination to enter DFU, then restore via Finder or iTunes.
DFU mode is advanced and bypasses the normal bootloader, which can fix deeper software issues, but it will erase the phone and requires technical care. Only use DFU when recovery mode and other resets fail.

After you complete the reset, your iPhone will either restart with default settings or be erased completely depending on the method you chose.
If you used a factory reset or restore, you can restore your backup during setup. If you only restarted or reset settings, your apps and data should still be there.

Start by backing up your data so you do not lose photos, messages, and app information. For simple trouble, try a soft restart or a force restart. These quick steps often fix apps that crash or a phone that is stuck. If networking is the problem, reset network settings. If system behavior is odd but your data is still important, use Reset All Settings. When you need a clean slate, Erase All Content and Settings will wipe everything and restore the phone to factory condition. If the device will not boot, recovery mode lets a Mac or Windows PC reinstall iOS, and DFU mode offers a deeper restore option when recovery mode does not work.
