Whether you are preparing to sell your iPhone 16, handing it over to someone else, or trying to resolve persistent software problems, erasing the device can give you a clean starting point. A factory reset removes the information and settings stored on the iPhone and returns it to the setup screen.
Before choosing this option, however, it is important to back up anything you want to keep. This guide covers the safest way to erase an iPhone 16, alternative methods when Settings cannot be accessed, eSIM considerations, and common problems you may encounter.

Things to Do Before Erasing Your iPhone
A factory reset is not something you should start without preparation. Once the erase process is completed, information stored locally on the iPhone is removed.
If you need your personal information later, create a backup first. Depending on your setup, you can use:
- iCloud
- Finder on a Mac
- Apple Devices on Windows
- iTunes on supported older Windows setups
To check your iCloud backup settings, open:
Settings → [Your Name] → iCloud → iCloud Backup
Make sure the backup has completed successfully before erasing the device.
If you are selling or giving away the iPhone, you should also make sure you have transferred any information you need and unpaired accessories such as an Apple Watch.
Factory Reset an iPhone 16 From Settings
If your iPhone is working normally and you can unlock it, using the built-in Settings option is the simplest approach.
1. Open the Transfer or Reset Menu
Start by opening Settings on your iPhone 16.
Then select:
General → Transfer or Reset iPhone
This section includes options for moving information to another iPhone as well as different reset choices.
2. Choose the Full Erase Option
Tap Erase All Content and Settings.
The iPhone will explain what will be removed during the process. Take a moment to review the information before continuing.
This option is different from resetting individual settings because it erases the device’s stored personal content.
3. Complete the Security Checks
Depending on your device configuration, Apple may ask you to enter your iPhone passcode and Apple Account password.
These verification steps help protect the device and are particularly important when Find My is enabled.
Enter the requested information and continue.
4. Confirm That You Want to Erase the Device
Follow the prompts and confirm the erase operation.
The iPhone will then begin removing its stored content and settings. You may see the Apple logo and a progress indicator while the process is underway.
Avoid interrupting the device while it is completing the reset.
5. Wait for the Hello Screen
After the erase has finished, the iPhone will restart and show the Hello setup screen.
At this point, you can either configure it as a new device or restore your information from a previously created backup.
What If You Cannot Access Settings?
A normal reset through Settings is not always possible. For example, the iPhone may be disabled, unresponsive, or inaccessible because the passcode has been forgotten.
In such situations, other options are available.
Restore the iPhone Using Recovery Mode
Recovery Mode can be used when you cannot normally access the iPhone.
Connect the device to a Mac or Windows PC and place the iPhone into Recovery Mode. You can then use Finder on a Mac or Apple Devices on Windows to restore the device.
The restore process reinstalls the operating system and erases the existing content.
If you have forgotten the device passcode, this method is generally more appropriate than trying to access the reset option from Settings.
Erase a Lost iPhone Remotely
If your iPhone is lost and you still have access to your Apple account, Apple’s Find My service can be used to remotely erase the device when the required conditions are met.
If the device has been permanently lost or transferred to another person, additional account-management steps may be necessary after the erase.
You Don’t Always Need a Full Factory Reset
A complete erase may be unnecessary if your goal is simply to fix a particular setting or connectivity problem.
The iPhone provides individual reset options under:
Settings → General → Transfer or Reset iPhone → Reset
Depending on the option selected, you can reset things such as:
- Network settings
- Keyboard dictionary
- Home Screen arrangement
- Location and Privacy settings
These options are useful when troubleshooting certain problems because they do not perform the same full-device erase as Erase All Content and Settings.
What Happens to an eSIM?
If your iPhone 16 uses an eSIM, pay attention to the option presented during the erase process.
You may be given a choice to keep the eSIM or erase the eSIM.
If you are continuing to use the iPhone and want to keep your existing cellular plan, keeping the eSIM may be appropriate. If you are preparing the phone for another person, erasing the eSIM may be the better choice.
If you are uncertain about what to select, contact your mobile carrier before completing the reset.
Common Problems During an iPhone Reset
The Erase Option Is Not Available
Restrictions on the iPhone can sometimes prevent certain settings from being changed. Check whether Screen Time restrictions are active and provide the required Screen Time passcode if prompted.
The Apple Account Password Doesn’t Work
Double-check that you are entering the credentials for the Apple Account associated with the iPhone. This is especially important when Find My is active.
The iPhone Remains on the Apple Logo
If the device becomes unresponsive during or around the reset process, a force restart may help.
If the problem continues, connecting the iPhone to a computer and using Recovery Mode to restore it may be necessary.
The Erase Process Seems Slow
Do not immediately assume that something has gone wrong. The process can take some time, particularly when the device contains a significant amount of data.
Keep the iPhone connected to power and allow the process to finish.
You Cannot Open Settings
If the device is disabled, frozen, or otherwise inaccessible, Recovery Mode provides an alternative way to erase and restore the iPhone using a computer.
Activation Is Requested After the Reset
After erasing the device, connect it to a reliable Wi-Fi or cellular network during setup. If Activation Lock is enabled, you may need the Apple Account that was previously associated with the iPhone.
Frequently Asked Questions
Does resetting an iPhone 16 delete all personal information?
Using Erase All Content and Settings removes the personal data and settings stored on the iPhone, including apps, photos, messages, accounts, and other locally stored information.
Should I back up my iPhone before resetting it?
Yes. If there is information you may want to use again, create a backup before starting the erase process.
Can I factory reset the iPhone without knowing the passcode?
You cannot normally perform the full erase through Settings without the required device authentication. If you have forgotten the passcode, Recovery Mode with a computer can be used to erase and restore the iPhone.
Can I get my data back after a factory reset?
A backup can allow you to restore your information during setup. Without a suitable backup, information that was stored only on the erased device may not be recoverable.
How long does an iPhone factory reset take?
The time can vary depending on the device and the amount of data being erased. It is best to keep the iPhone connected to power and wait until the process has completed.
A Few Final Checks Before You Erase
Before tapping the final erase option, make sure you have:
- Backed up important photos, messages, and other data
- Transferred anything you want to keep
- Checked your Apple Account credentials
- Unpaired your Apple Watch if you are giving away the iPhone
- Considered whether the eSIM should be kept or erased
- Kept the device connected to power if necessary
Final Takeaway
Resetting an iPhone 16 is relatively simple when the device is accessible and functioning normally. The built-in Erase All Content and Settings option provides the most straightforward way to prepare the phone for a fresh setup or a new owner.
The most important step is to prepare beforehand. Back up anything you need, check your account credentials, and carefully review the erase options—particularly if the iPhone uses an eSIM.
For devices that cannot be accessed normally, Recovery Mode provides an alternative way to restore the iPhone. And if you are troubleshooting a smaller problem, consider one of the individual reset options before choosing a complete factory reset.
