How to back up and format your phone?

Upgrading your smartphone – should you sell it or give it away? Before you wipe it, back up your data to avoid any loss. Here’s how to do it quickly and efficiently.

 

💾 Why is backing up important?

Backing up regularly protects your data against:

  • Accidental loss (theft, damage, human error)
  • Changing phones
  • The risk of cyberattacks or malware

 

☁️ Backing up your important data:

On iPhone:

  1. Open Settings
  2. Select your name
  3. Tap iCloud
  4. Select iCloud Backup
  5. Tap Back Up Now

💡 Good to know: Since iOS 18, Apple has offered a built-in password manager, making it easier to recover login details after a reset.

 

On Android:

  1. Open Settings
  2. Select Accounts and backup
  3. Tap Data backup
  4. Choose what to back up (photos, contacts, Google data, etc.)

 

💡 Check your backup: Once the backup is complete, make sure all your important data (photos, apps, contacts, etc.) has been saved correctly. 

 

📂  Choose your backup method:

Select the backup method that best suits your needs:

Cloud backup:

  • iPhone: Use iCloud
  • Android: Use Google Drive

Local backup:

  • iPhone: Use iTunes or Finder (on macOS Catalina and later)
  • Android: Use tools such as Samsung Smart Switch

Manual backup:

  • Transfer your photos and videos to a computer via USB
  • Back up important documents to cloud services such as Google Drive or Dropbox

💡 Tip: Cloud backup remains the quickest and easiest option.

 

🔐 Protect your sensitive information:

Before resetting your device or handing it over:

  • Sign out of all your accounts (Google, Apple ID, etc.)
  • Delete passwords saved in your browsers
  • Delete any personal files you do not wish to share

 

⚠️ Warning: Some apps, such as WhatsApp, Telegram, Luxtrust, MyGuichet and your banking apps, will automatically log you out after a reset. Make sure you have the necessary login details and recovery methods for these apps.

💡 Good to know: Use Apple’s password manager or Google Password Manager on Android to securely back up your login details before resetting your device. 

 

🔄 Format your device:

Once your data has been safely backed up, reset your phone to its factory settings.

On iPhone:

  1. Open Settings
  2. Select General
  3. Tap Transfer or Reset iPhone
  4. Select Erase All Content and Settings
  5. Confirm with your Apple ID

 

On Android:

  1. Open Settings
  2. Select General Management
  3. Tap Reset
  4. Select Factory data reset
  5. Confirm with your PIN or password

 

🔄 Restoring your data after a reset:

When setting up your new device or after resetting your old one:

  1. Restore your backup: Choose to restore from your cloud or local backup during setup.
  2. Reconnect your accounts: Log in to your essential apps and services.
    • Apps such as WhatsApp, Telegram, Luxtrust, MyGuichet and your banking apps will require your login credentials.
    • For banking or administrative apps, additional verification steps (SMS codes, biometric authentication) may be required.
  3. Reinstall and check the apps: Ensure that all necessary apps are working properly and that your data has been successfully restored.
