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

If you're moving from an iPhone to another iPhone, use iCloud or a wired connection — both transfer everything in one go. If you're moving from Android to Android, Google's built-in transfer tool works the same way. Switching between systems (iPhone to Android or vice versa) requires a different approach because the operating systems don't talk to each other directly. The method you choose affects how long the transfer takes, whether you need passwords, and what data actually moves over.

Most transfers happen automatically if you sign into your existing accounts on the new phone. Your email, photos, contacts, and calendar sync back down from the cloud. Apps reinstall from the app store. The catch: some apps don't transfer their internal data — your game progress, chat history, or banking app settings may not come with you, even though the app itself does.

Key Takeaways

  • iPhone to iPhone: use iCloud backup or plug both phones together with a cable for the fastest, most complete transfer.
  • Android to Android: use Google's built-in transfer tool during setup, which moves contacts, calendar, photos, and app data automatically.
  • iPhone to Android or Android to iPhone: sign into your Google or Apple account on the new phone, then manually move photos and messages through cloud storage or email.
  • Some apps store data only locally and won't transfer automatically — check your banking, gaming, and messaging apps after the move to see what needs to be set up again.
  • Back up your old phone before starting any transfer, in case something goes wrong.

iPhone to iPhone: the simplest route

When you turn on a new iPhone, it asks whether you want to restore from a backup. Choose "Restore from iCloud Backup" and sign in with your Apple ID. The phone downloads everything that was on your old iPhone — apps, photos, messages, settings, even your home screen layout. This takes anywhere from 30 minutes to several hours depending on how much data you have and your internet speed.

If you want to move data without waiting for a download, use a wired transfer instead. Turn on the new iPhone, tap "Migrate from iPhone," and hold the old phone next to it. The phones talk to each other directly over a local connection, which is faster than going through iCloud. You'll need to enter your Apple ID password, and both phones need to stay close together until the transfer finishes.

Before you start either method, make sure your old iPhone has a recent backup. Open Settings, tap your name, then iCloud, then iCloud Backup. Tap "Back Up Now" and wait for it to finish. This ensures nothing gets lost if something interrupts the transfer.

Android to Android: using Google's transfer tool

When you set up a new Android phone, the setup wizard asks if you want to restore from a backup. Tap "Copy your data" and sign in with the Google account you used on your old phone. The phone then downloads your contacts, calendar events, Gmail, photos from Google Photos, and app data that Google has stored in the cloud.

This method doesn't move everything — text messages, call history, and some app data stay on your old phone unless you've specifically backed them up to Google. If you want those too, go back to your old phone before you sell or recycle it. Open Settings, search for "backup," and look for options to back up messages and call logs. Different Android manufacturers (Samsung, Google Pixel, OnePlus) have slightly different backup tools, so the exact steps vary.

After the initial transfer finishes, your apps reinstall from the Google Play Store automatically. This can take a while if you have many apps. Keep the phone plugged in and on Wi-Fi while it's installing, and don't interrupt it.

Switching from iPhone to Android

Your photos, contacts, and calendar move easily because they're stored in iCloud, which Android can read. Sign into your iCloud account on the new Android phone through the Settings app, and your contacts and calendar sync down. For photos, use Google Photos: install it on your iPhone, let it back up your photo library to your Google account, then sign into that same Google account on the Android phone and your photos appear.

Text messages and iMessage conversations don't transfer automatically. If you need them, take screenshots of important conversations before you switch, or use a third-party app like Samsung Smart Switch (if you're buying a Samsung) or Google's Phone Clone app, which can pull some message data from an iPhone backup file. These tools aren't perfect and may not capture everything, so don't rely on them for critical information.

Apps you bought on the iPhone don't transfer — you'll need to download them again from the Google Play Store. Many are free or have free versions. Paid apps you bought on iPhone won't be refunded, and you may need to buy them again on Android, though some developers offer discounts for switching users.

Switching from Android to iPhone

Apple's "Move to iOS" app, available on the Google Play Store, transfers contacts, calendar events, photos, and some app data from Android to iPhone. Install it on your Android phone, open it during iPhone setup, and follow the prompts. The two phones connect over Wi-Fi and the Android phone sends your data to the new iPhone.

This method works best if you're moving from a newer Android phone. Older phones or heavily customized versions may not transfer everything. Text messages, call history, and some app data often don't come over, so check those manually after the transfer finishes.

Like switching to Android, your apps need to be downloaded again from the App Store. Photos stored in Google Photos or OneDrive will sync if you sign into those accounts on the iPhone. Gmail, contacts, and calendar all sync through your Google account once you add it to the iPhone's Settings.

What usually doesn't transfer automatically

Banking apps, messaging apps, and games often store data only on your phone, not in the cloud. Your banking app will install on the new phone, but you'll need to log in again — the app doesn't remember your password or your saved accounts. The same goes for WhatsApp, Telegram, and other messaging apps: the app transfers, but your chat history may not unless you've backed it up through the app's own backup feature.

Check these apps after your transfer finishes and set them up again if needed. Most have a "restore from backup" option in their settings. Some apps (like WhatsApp) let you back up to Google Drive or iCloud, so if you set that up before switching, the restore happens automatically when you log in on the new phone.

Passwords stored in your phone's password manager usually do transfer if you're staying within the same ecosystem (iPhone to iPhone, Android to Android). If you're switching systems, your passwords stay in your old phone's manager and don't move over. Use a password manager like Bitwarden or 1Password that works across both systems, or manually export your passwords before you switch.

Backing up before you transfer

Before you start any transfer, back up your old phone completely. For iPhone, go to Settings, tap your name, then iCloud, then iCloud Backup, and tap "Back Up Now." For Android, open Settings, search for "backup," and follow the prompts for your phone's backup tool (Google Backup, Samsung Cloud, or whatever your manufacturer uses).

This backup sits in the cloud and stays there even after you've transferred to the new phone. If something goes wrong during the transfer, or if you realize you forgot something, you can go back to your old phone and try again, or restore from the backup on a different device later.

Frequently Asked Questions

Do I need to know my passwords to transfer my data?

Not for most data. Contacts, photos, calendar, and email sync through your existing account (Apple ID or Google account) without needing individual passwords. Apps reinstall automatically. You'll need your account password only if you're signing into a new account or if an app requires you to log in fresh on the new phone.

What if my old phone breaks before I can transfer?

If you have a recent backup in iCloud or Google Drive, you can restore to the new phone from that backup without the old phone. If you don't have a backup, contacts and calendar may still be recoverable through your email account, but photos and messages are usually lost.

Can I transfer data from a very old phone?

It depends on how old. If the phone still turns on and connects to Wi-Fi, you can usually back it up and restore to the new phone. Very old phones (more than 8 to 10 years) may not support current backup systems, in which case you'll need to manually move what you can through email or cloud storage.

Will my apps work the same on the new phone?

Most will, but some app data doesn't transfer. Games may lose your progress, banking apps may need to be set up again, and some settings within apps reset to defaults. Check your most-used apps after the transfer and set them up again if needed.

How long does a transfer usually take?

A wired iPhone-to-iPhone transfer or Android-to-Android transfer through the setup wizard usually takes 30 minutes to an hour. Cloud-based transfers (iCloud or Google) can take several hours depending on how much data you have and your internet speed. Apps reinstalling from the app store can add another 30 minutes to an hour.
