If you feel that your iPhone is starting to be sluggish and are ready to get a new one, you’ll want to wipe all personal data from the device.

So, how can you wipe all personal data from your phone? Here’s the whole process:
Unlink your iPhone from other devices and services
- Go to Settings and tap Find My
- Select My Phone
- Deactivate the Find my Phone and Find My Network features
You should also unpair any wireless headphones or watches that you have connected to the iPhone. Also, turn the iMessage app off in the iPhone’s Settings menu.
Sign out of your Apple ID

The next step is to disconnect your device from your Apple ID:
- Open Settings and tap your account name
- Tap the Sign Out located at the bottom of the page
- Confirm by entering your Apple ID password
- Decide if you want to keep a copy of the data or not
- Tap Sign Out again and confirm your action
Perform a full wipe

Now that your device has been unlinked from your apps, devices, and accounts, you can perform a full wipe and delete all the data:
- Take your SIM card out of the phone
- Go to Settings > General > and select Transfer or Reset iPhone
- Tap on Erase All Content and Settings
