The fastest way depends on what phone you're switching to

If you're moving from an iPhone to another iPhone, or from an Android phone to another Android phone, your phone's built-in transfer tool will move most of your data automatically — contacts, photos, messages, apps, and settings. If you're switching between iPhone and Android, the process is slower and requires more manual steps, because the two systems don't share a direct transfer method. Either way, you'll need both phones, your passwords, and about 30 minutes to an hour of uninterrupted time.

The key decision is whether to transfer everything at once during setup, or to move specific items afterward. Moving everything at setup is simpler and catches more data, but it requires your old phone to be charged and nearby. Moving items later gives you more control and lets you leave your old phone behind, but you'll need to remember what you didn't transfer.

Key Takeaways

  • iPhone to iPhone: Use Quick Start during setup to transfer everything wirelessly in one step, or use iCloud if your old phone isn't available.
  • Android to Android: Use Samsung Smart Switch, Google's built-in transfer tool, or your carrier's app, depending on which phones you own.
  • iPhone to Android or Android to iPhone: Use Google's Move to iOS app or Samsung's Smart Switch, then manually transfer photos and files afterward.
  • Before you start, charge both phones fully, have your passwords ready, and make sure you're connected to Wi-Fi.
  • Apps will reinstall on the new phone, but you'll need to log into each one separately — your passwords don't transfer automatically.

iPhone to iPhone: Quick Start is the simplest route

When you turn on a new iPhone for the first time, it will ask if you want to restore from a backup. Choose "Restore from iPhone" and hold your old iPhone nearby. The two phones will connect wirelessly and transfer your data in the background while you complete the setup screens. This method moves contacts, messages, photos, app data, and most settings without you having to do anything else.

Quick Start requires both phones to be on the same Wi-Fi network and your Apple ID password. If your old phone isn't available or won't turn on, you can instead restore from an iCloud backup — sign into your Apple ID on the new phone during setup and choose the most recent backup. This takes longer (usually 15 to 30 minutes depending on how much data you have) because it downloads from Apple's servers rather than transferring locally, but it works even if your old phone is gone.

After the transfer finishes, your apps will reinstall automatically, but you'll need to log into each one. Messages and call history transfer, but iMessage and FaceTime may take a few minutes to activate on the new phone. If you use a SIM card, insert it into the new phone after setup completes.

Android to Android: The method depends on your phone brand

Samsung phones come with Smart Switch built in. Turn on your new Samsung, tap "Bring data from old device" on the setup screen, and choose "Wireless" if your old phone is nearby or "USB cable" if you want to connect them directly. Smart Switch will transfer contacts, messages, photos, apps, and settings. If your old phone isn't a Samsung, you can still use Smart Switch by downloading the app from the Google Play Store on both phones.

If you have a Google Pixel or another Android phone that isn't a Samsung, look for "Set up your device" or "Restore from backup" during the initial setup. Sign into your Google Account and choose the backup you want to restore. Google's transfer tool moves most data, though some app settings may not carry over perfectly. You can also manually transfer photos and files by connecting your old phone to a computer, copying the files, and then connecting your new phone.

After any Android-to-Android transfer, apps will reinstall from the Google Play Store, but you'll need to log into them. Some apps may ask for permissions again. If you use a SIM card, move it to the new phone after setup is complete.

iPhone to Android: Use Google's Move to iOS app

Google's Move to iOS app is available free on the Apple App Store. Install it on your iPhone, open it, and follow the prompts to connect to your new Android phone. The app will transfer contacts, calendar events, photos, and videos over Wi-Fi. It does not transfer messages, call history, or app data — those require manual steps afterward.

After the transfer finishes, you'll need to download your apps from the Google Play Store on the Android phone. Your app accounts won't transfer, so you'll log into each one separately. For messages, you can export them from your iPhone using a third-party app and then import them into Android messaging apps, but this is manual and not all apps support it. Most people accept that messages don't transfer and start fresh on the new phone.

Photos and videos transfer to your Google Photos library, which you can access on the Android phone by signing into your Google Account. If you have files stored in iCloud, you'll need to download them on a computer and then transfer them to the Android phone via USB cable or by uploading them to Google Drive.

Android to iPhone: Use Samsung Smart Switch or manual transfer

If your Android phone is a Samsung, download the Move to iOS app on your iPhone during setup. Your Samsung will send contacts, calendar events, photos, and videos to the iPhone. If your Android phone is not a Samsung, you'll need to transfer data manually: export your contacts as a file, upload photos to Google Photos or another cloud service, and download them on your iPhone.

Messages and call history do not transfer from Android to iPhone through any automated tool. You can export messages from your Android phone using a third-party app and then try to import them into iPhone messaging apps, but support varies. Most people accept that message history stays on the old phone and start fresh on the iPhone.

Apps will need to be downloaded from the Apple App Store on your new iPhone, and you'll log into each one separately. If you use Google services like Gmail, Google Calendar, or Google Photos, sign into your Google Account on the iPhone to access them. Files stored on your Android phone can be uploaded to Google Drive or another cloud service and then downloaded on the iPhone.

What doesn't transfer automatically and how to handle it

App passwords and login information do not transfer between phones, even when using the same operating system. You'll need to log into each app on your new phone. If you've forgotten a password, use the app's "Forgot password" option before you switch phones, or reset it on your new phone after transfer. Two-factor authentication codes may not transfer either — if an app requires a code to log in, you may need to set up a new authentication method on the new phone.

Messages and call history transfer within the same operating system (iPhone to iPhone, Android to Android) but not between them. If you're switching from iPhone to Android or vice versa, your message history will remain on the old phone. Some messaging apps like WhatsApp and Telegram have their own backup and restore features — check the app's settings before you switch to see if you can back up your chat history.

Banking apps, payment apps, and other security-sensitive apps usually require you to log in fresh on the new phone for security reasons. This is intentional and protects your accounts. Voicemail may not transfer — contact your carrier to set up voicemail on the new phone if it doesn't activate automatically.

Steps to take before you hand over your old phone

Before you sell, trade in, or give away your old phone, sign out of your accounts. On iPhone, go to Settings > [Your Name] > Sign Out and enter your password. On Android, go to Settings > Accounts and remove your Google Account. This prevents someone else from accessing your email, photos, and other data stored in those accounts.

Erase the phone completely. On iPhone, go to Settings > General > Transfer or Reset > Erase All Content and Settings. On Android, go to Settings > System > Reset Options > Erase All Data. This removes all your personal information and returns the phone to factory settings. If you're trading the phone in to a carrier or retailer, they may do this step for you, but it's safer to do it yourself first.

Remove your SIM card and any memory cards before handing over the phone. If you're keeping your phone number, your carrier will move it to the new phone — you don't need to do this yourself, but tell the carrier which phone you're switching to.

Frequently Asked Questions

Do I need both phones at the same time to transfer data?

Not always. If you're using iCloud (iPhone) or Google Backup (Android), you can restore from a backup on your new phone even if your old phone is lost or broken. However, Quick Start (iPhone to iPhone) and Smart Switch (Android to Android) work faster if both phones are nearby and connected to Wi-Fi.

Will my text messages transfer to my new phone?

Yes, if you're staying on the same operating system. iPhone to iPhone and Android to Android both transfer messages automatically. If you're switching from iPhone to Android or Android to iPhone, messages do not transfer — they stay on your old phone. Some messaging apps like WhatsApp have separate backup features you can use.

Do I need to charge my old phone before transferring?

Yes. Charge both phones to at least 50% before you start. If your old phone dies during the transfer, the process may stop or fail. If you're using a cloud backup instead of a direct transfer, you only need to charge the new phone.

What happens to my apps when I switch phones?

Apps reinstall automatically on your new phone if you're using the same operating system. If you're switching from iPhone to Android or vice versa, you'll need to download each app from the new phone's app store. You'll need to log into each app separately — app passwords don't transfer.

Can I transfer my data to my new phone after I've already set it up?

Yes. You can transfer photos, contacts, and files manually at any time using cloud services like Google Drive, iCloud, or OneDrive. However, some data like app settings and call history are easier to transfer during initial setup. If you've already set up your new phone, you can still move photos and files, but you may need to re-download and set up apps.
