Fully wipe the iPhone back to factory condition
Erase All Content and Settings permanently deletes everything on the iPhone, including apps, photos, settings, and accounts, restoring it to an out-of-box state, distinct from resetting individual settings categories.
How to open Erase All Content and Settings
- Open Settings and tap General.
- Tap Transfer or Reset iPhone.
- Tap Erase All Content and Settings.
- Enter the device passcode and Apple ID password when prompted.
- Confirm to begin the erase process.
What you should know
- Found in Settings > General > Transfer or Reset iPhone > Erase All Content and Settings.
- Requires the device passcode and Apple ID password to confirm before erasing.
- Automatically removes the device from Find My and deactivates Activation Lock upon completion when signed out properly.
- Distinct from Reset options, which reset only specific categories like network or keyboard settings without deleting personal data.
This action is irreversible without a prior backup; ensure an up-to-date iCloud or computer backup exists before proceeding.
Why it matters
This is the appropriate step before selling, trading in, or giving away an iPhone, since it removes every trace of personal data, accounts, and files rather than just resetting configuration preferences. It's also a legitimate troubleshooting step of last resort for persistent software issues that survive a restart, reset, or even a reinstalled update. Because it's irreversible without a backup, understanding exactly what it does, and how it differs from the narrower Reset options, prevents accidental data loss from choosing the wrong menu item.
Best practices
- Create a fresh backup immediately before erasing, whether to iCloud or a computer.
- Sign out of Find My and the Apple ID beforehand if planning to transfer the device to someone else, to fully remove Activation Lock.
- Only use this for a full wipe; use the narrower Reset options if only specific settings need to be cleared.
Common problems and fixes
- The next owner can't activate the iPhone after receiving it.
- The previous owner needs to remove it from their Find My device list, or the erase process needs to be completed with full Apple ID sign-out beforehand.
- Erasing seems stuck or is taking a long time.
- Keep the device connected to power and Wi-Fi and avoid interrupting it, since a full erase of large storage can take some time.
Tips and tricks
- Check Settings > General > iPhone Storage beforehand to make sure nothing important is unsynced before erasing.
Frequently asked questions
Does this remove the device from Find My automatically?
Yes, when the process completes normally while properly signed into Apple ID, it also disables Activation Lock.
Can data be recovered after this is used?
Generally no, without a backup made beforehand; the erase process is designed to be unrecoverable.
