If you have an iPhone, you're in luck. Even six-year-old iPhones can earn you about £100. And if you still have the original box, it’s weirdly worth more.1. The watch has got to goIf you’re an Apple Watch kind of person, you'll need to unpair it from your iPhone. Don't worry, the watch will automatically back up your data. You'll need to sit both devices next to each other while they unpair.To Unpair: Open the Apple Watch app> "My Watch" tab> Press the i button> Unpair Apple Watch2. The safer the betterNow, onto your phone. Don’t lose the data you’re trying to secure – back it up first. If you have an iCloud account, you can start the backup on your iPhone, as long as you're on WiFi. Otherwise, use iTunes.Create Backups: Settings> Apple ID> iCloud> iCloud Backup> Backup Now3. Sign out of your Apple IDIf you don’t do this, data you’ve backed up previously could be deleted in the next few steps.Apple ID: If you are using iOS 10.3 or later: Settings> Apple ID> Sign OutIf you're using iOS 10.2 or earlier: Settings> iCloud> Sign out> "Delete from my iPhone"> Settings> iTunes & App Store> Apple ID> Sign outAlso very important: delete all of your messages.Settings> Messages> "iMessage" slide to "Off"
ERASING YOUR IPHONE
4. Delete photos and apps individuallyThis will be an Olympic exercise in patience, because Apple doesn’t let you delete all of your photos at once. Consider it a (potentially lengthy) trip down memory lane.5. If you don’t need your iMessages any more, deleteIf you’re planning on switching to a non-Apple device, it’s best to delete your number from Apple. To do this, click this link and follow the instructions.6. The big red button: factory resetFinally, the time has come to press the built-in reset button, brought to you by Apple.

Keep in mind that, depending on your brand of Android, your settings may be labeled slightly differently.1. Keep your data safeYes, this also applies to Android users: if you’re planning to wipe your data, make sure you back it up first.Backup: Settings> System> Backup2.

To deactivate FRP, you need to switch off your screen lock on some devices and then remove your Google account (below).
ERASING YOUR ANDROID PHONE
Turn off FRP: Settings> Security or Screen Security> Screen Lock switch to "Off"3. Log out of GoogleYou don't need to log out of apps like Facebook, TikTok and Instagram individually, but you should at least log out of your Google account. This prevents data from being deleted from your backup when you reset.Logout of Google: Settings> Accounts> click on Google account> "Remove Accounts"4. Lock the front door: turn on encryptionThis one is important. Because a simple reset does not necessarily delete all data, you’ll need to encrypt your device. This means that the new owner won’t be able to access your data – even if they try. For Android users on 6.0 Marshmallow and later, encryption is automatically turned on.Encrypt: Settings> Security> Advanced> Encryption & access data> Encryption on "On"5. Upload some fake dataEven once you’ve deleted data, Android phones will store it until something is saved on top of it. So, if you really want to be on the safe side, you’ll need to overwrite anything lurking beneath the surface. You can download random videos to fill up space, or use an app like Secure Eraser to do it for you.6. The Big Red ButtonYou’ve put a lot of effort into destroying all traces of yourself from your phone. At last, it's time to hit Reset.Reset: Settings> System> Advanced> Reset options> Erase all data (factory reset)7. Make Google forget it ever happenedYou’ll forget all about your old phone as soon as you get your hands on a new one, but Google won’t forget that easily. To delete your phone from your Google account, go to Google device management, press the three dots and log out of the device.No matter the brand, your phone is now ready to be passed on to its next owner. Your photos and accounts are safe – and you’ve made some money.
