How To Reset iPhone 15: Step-by-Step Guide to Restore

Resetting an iPhone 15 can mean a simple restart, a force restart for frozen screens, or a full factory reset that erases everything. First, back up your data. Then choose the reset type you need: restart to fix minor glitches, force restart if the phone is unresponsive, or erase all content for a fresh start or to sell the device. Follow the steps below and read the tips so you don’t lose anything important.

How To Reset iPhone 15 – Step-by-Step Tutorial

These steps will show you how to restart, force-restart, reset settings, erase everything, erase remotely, and restore from a computer. Pick the step that fits your problem and follow the details under each step.

Step 1: Soft restart using buttons or Settings.

A soft restart turns the phone off and on to clear temporary glitches without deleting data.

To do this with buttons, press and hold either volume button and the side button until the power-off slider appears, then slide to power off and turn it back on after 10–30 seconds. You can also go to Settings > General > Transfer or Reset iPhone > Shut Down and drag the slider. This is the safest first move when apps crash or the phone runs slowly.

Step 2: Force restart when the phone is frozen.

A force restart forces the iPhone to reboot and is used only if the screen is unresponsive.

Press and quickly release Volume Up, press and quickly release Volume Down, then press and hold the Side button until the Apple logo appears, then release. This won’t erase your data; it just forces the system to reboot.

Step 3: Reset All Settings to restore defaults but keep data.

Reset All Settings returns system settings to factory defaults while leaving your apps, photos, and media intact.

Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings, enter your passcode, and confirm. This clears Wi‑Fi passwords, display settings, keyboard dictionary, and privacy settings but preserves personal files.

Step 4: Erase All Content and Settings for a full factory reset.

Erase All Content and Settings wipes the phone clean and prepares it for a new owner or a fresh start.

Open Settings > General > Transfer or Reset iPhone > Erase All Content and Settings, then follow the prompts and sign in with your Apple ID to disable Activation Lock if prompted. Make sure you have a backup before doing this because it deletes everything on the device.

Step 5: Erase remotely with Find My if the phone is lost or you can’t access it.

If the phone is lost or stolen, you can remotely erase it in iCloud to protect your data.

Sign in to iCloud.com or use the Find My app on another device, select the iPhone 15, and choose Erase iPhone; the device will be wiped when it’s online. This requires your Apple ID and that Find My was enabled on the device beforehand.

Step 6: Restore using a computer (Recovery Mode) or use DFU for deep restores.

Use a Mac or PC with Finder/iTunes to restore iOS when the phone won’t update or restore normally.

Connect the iPhone to the computer, put it into recovery mode (quick press Volume Up, quick press Volume Down, then hold Side until recovery screen appears), then choose Restore in Finder/iTunes. DFU mode is more advanced and can fix deeper software issues, but it’s trickier; follow official Apple instructions or get help if you’re unsure.

After these steps, the phone will reboot or be erased, depending on which action you chose. A soft or force restart simply refreshes the system and keeps your data. A factory reset removes everything, and if Find My is on, Activation Lock will require your Apple ID to reactivate the phone.

How To Reset iPhone 15 Tips

• Make a backup first using iCloud or Finder/iTunes so you can restore your data later.
• Charge the iPhone above 50% or keep it plugged in before a full erase or restore.
• Sign out of apps like iCloud, iMessage, and App Store when prepping the phone for sale.
• If you forget your Apple ID password, reset it at iforgot.apple.com before erasing to avoid Activation Lock problems.
• Use Recovery Mode on a computer rather than DFU for a simpler, safer restore.
• Keep your USB-C cable and a compatible computer handy for restores to avoid interruptions.
• Update iOS if the phone is usable first. Sometimes updates fix issues without a reset.
