The iPhone is probably the most used device in your life, filled with sensitive data and information, including messages, photos, videos, contacts, credit cards, passwords, and much more.

When the time comes to purchase a new one, you must ensure you have a backup of all of your important information before you even think about erasing your iPhone.

If you've purchased a new device, like the iPhone 15, you want to make sure you have transferred all your data to the new iPhone. If you've moved your data across before selling or giving the iPhone to a loved one, you'll need to erase all the personal data.

It's super easy to erase your iPhone, and here's how to do it.

How to back up your iPhone or iPad before wiping it

Before you do anything else, you'll need an up-to-date backup of your iPhone so that the information you erase is stored somewhere. iCloud automatically creates a backup overnight as long as you're plugged in and on Wi-Fi, but a manual backup will make sure you're absolutely up to date.

  1. Make sure your iPhone or iPad is connected to Wi-Fi. (If you're low on power, plug-in the device as well)
  2. Launch Settings from the Home screen
  3. Tap on the Apple ID banner at the top
  4. Tap iCloud

Wait for your iPhone backup to complete before moving forward. You can also back up your iPhone or iPad with a computer, this might be a better option if you're pressed for time.

How to erase all data from your iPhone or iPad

iOS makes erasing your device simple and returns you to the setup process after so that you have a clean device to start over with or sell.

  1. Launch the Settings app from the Home screen of your iPhone or iPad
  2. Now tap on General
  3. Scroll to the bottom and tap Transfer or Reset iPhone

Once the process is complete, you can give or sell your device to someone else without any worries of a personal data breach.

One more thing... My precious

Everyone should treat their data like Gollum treats the One Ring, especially considering nowadays, your whole life is essentially stored on your iPhone.

It's so important to ensure you erase your device before giving it away or selling it, as identity fraud is a very real issue that you need to be aware of.

Make sure your device is backed up, and then erase your iPhone; It's incredibly simple to do but easy to forget about. Don't be the person who sells an iPhone to a stranger without removing credit card information and passwords only to wonder why you've got an unauthorized purchase on your card statement the next month.

If you're giving away an old Mac or you've bought yourself a new one, you'll need to do the same thing. Follow our how to transfer data to your new Mac from your old Mac guide.
