Let's get your new phone set up.

• Charge both phones and connect to Wi-Fi.
• Know your Apple Account password and your old phone's passcode.
• Back up WhatsApp on your old phone: WhatsApp → Settings → Chats → Chat Backup → Back Up Now.

• From an iPhone: turn on the new one and hold it next to your old one. Quick Start does the rest.
• From an Android: when your iPhone asks, choose Move Data from Android, then open Move to iOS on the old phone.

• Physical SIM: move it across with a SIM tool.
• eSIM: your iPhone offers to transfer it during setup. If it doesn't, your network can move it.

A transfer moves your email accounts across, but often not their passwords. If Mail is quiet or asks for a password:

• Go to Settings → Apps → Mail → Mail Accounts, tap the account and enter the password again.
• Not listed? Tap Add Account.
• Use the Gmail or Outlook app? Open it and sign in there.
• Work email may need a code from your IT team or authenticator app.

• WhatsApp: sign in with your number and restore the backup from step 1.
• Banking apps: sign in again. Most ask to register the new phone, often with a code to the old one.
• Authenticator apps: move them across before going further. Each has its own transfer option.

• Set up Face ID and a passcode.
• Turn on Settings → your name → Find My → Find My iPhone.
• Turn on Settings → Face ID & Passcode → Stolen Device Protection.

Once everything's on your new phone:

• Sign out of your Apple Account: Settings → your name → Sign Out. This turns off Find My.
• Then erase it: Settings → General → Transfer or Reset iPhone → Erase All Content and Settings.

• Keep Settings → Battery → Charging → Optimised Battery Charging on. iPhone 15 and later can also stop at 80%.
• Avoid heat: car dashboards, sunny windowsills, charging under a pillow.

• Charge both phones and connect to Wi-Fi.
• Know your Google account password and your old phone's PIN.
• Back up WhatsApp: WhatsApp → Settings → Chats → Chat backup → Back up.

• From an Android: during setup, choose Copy apps & data, by cable or wirelessly.
• Samsung Galaxy: use Smart Switch. It's built in.
• From an iPhone: choose to copy from an iPhone during setup, and connect with a cable.

• Physical SIM: move it across with a SIM tool.
• eSIM: transfer it from your SIM settings, or ask your network.

A transfer moves your email accounts across, but often not their passwords. If your email is quiet or asks for a password:

• Gmail: tap your profile picture, then Add another account.
• Samsung Email: open it and enter each password again.
• Outlook or Yahoo? Sign in again inside the app.
• Work email may need a code from your IT team.

• WhatsApp: restore your backup from Google Drive when it asks.
• Banking apps: sign in again. Most ask to register the new phone, often with a code to the old one.
• Authenticator apps: move them across before going further. Each has its own transfer option.

• Set a screen lock and add your fingerprint.
• Turn on Find My Device. Galaxy owners: Find My Mobile too.

Once everything's on your new phone:

• Remove your Google and Samsung accounts: Settings → Accounts.
• Then factory reset it.

• Keep Adaptive Battery on.
• Galaxy: turn on Protect battery so it doesn't sit at 100% overnight.
• Avoid heat: car dashboards, sunny windowsills, charging under a pillow.
