The fastest way depends on what kind of 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 — photos, contacts, messages, apps, and settings. If you're switching between iPhone and Android, or if the automatic route doesn't work, you'll need to transfer some things manually or use a third-party tool. The method you choose affects how much time you spend and whether you lose anything along the way.

Start by deciding whether you want a complete transfer or just the essentials. A complete transfer takes longer but means you won't have to re-download apps or reset preferences. A partial transfer is faster but requires you to rebuild some of your phone's setup afterward.

Key Takeaways

  • iPhone to iPhone: use iCloud or Quick Start to transfer everything in one process, which takes 30 minutes to a few hours depending on how much data you have.
  • Android to Android: use Google's built-in transfer tool during setup, or use Samsung Smart Switch if both phones are Samsung devices.
  • iPhone to Android or Android to iPhone: you'll need to transfer contacts, photos, and messages separately because the systems don't sync automatically.
  • Before you start, back up your old phone and write down passwords for email and important apps, because you'll need them on the new phone.
  • Apps don't always transfer perfectly — you may need to re-download some and sign back into them with your username and password.

iPhone to iPhone: using Quick Start or iCloud

Quick Start is the fastest method if both phones are in front of you. Turn on your new iPhone and hold it next to your old one. Your old phone will show a setup screen; follow the prompts to scan a code with your old phone's camera. Your new phone will then download your Apple ID, settings, and apps from iCloud automatically. This process takes 30 minutes to several hours depending on how much data you have and your internet speed.

If your old iPhone isn't available or won't turn on, use iCloud instead. On your new iPhone, go to Settings > [Your Name] > iCloud and sign in with your Apple ID. Turn on the toggle for iCloud Backup, then go back to the home screen and open the Settings app again. Tap General > Transfer or Reset > Restore from iCloud Backup and choose the backup you want to restore. This method also takes several hours but doesn't require your old phone to be present.

Both methods transfer your photos, messages, contacts, app data, and home screen layout. Some apps may need you to sign back in after the transfer completes. If you have a lot of data, make sure both phones are plugged in and connected to Wi-Fi before you start.

Android to Android: using Google's built-in transfer or Samsung Smart Switch

If both phones are Android devices, the easiest method is Google's transfer tool, which works during the initial setup. When you turn on your new Android phone for the first time, you'll see a screen asking whether you want to copy apps and data from another device. Tap "Copy your data" and follow the prompts to sign in with your Google account. Your new phone will then download your contacts, calendar, photos, messages, and apps from Google's servers.

If you have two Samsung phones, Samsung Smart Switch offers a more complete transfer. Download the Smart Switch app on both phones, open it on your new phone, and select "Receive data." On your old phone, open Smart Switch and select "Send data." Choose whether to transfer wirelessly or using a USB cable. Wireless transfer is slower but doesn't require a cable; USB transfer is faster but requires a cable and an adapter if your phones use different connector types.

Google's method takes 30 minutes to a few hours depending on your data size and internet speed. Samsung Smart Switch can take longer if you're using a wireless connection. Both methods transfer apps, contacts, messages, photos, and settings. You may need to sign back into some apps after the transfer.

iPhone to Android: transferring contacts, photos, and messages separately

There is no automatic transfer tool between iPhone and Android, so you'll need to move your data in pieces. Start with contacts: on your iPhone, open Settings > [Your Name] > iCloud and make sure Contacts is turned on. Then open Contacts, tap Groups in the top left, and make sure "All Contacts" is selected. Go back to the main Contacts screen, tap the three dots in the top right, and select "Export vCard." Email the file to yourself or save it to your Google Drive. On your new Android phone, open Google Contacts, tap the menu icon (three horizontal lines), select "Import," and choose the vCard file you saved.

Photos and videos are easier: on your iPhone, open the Photos app, select the photos you want to move, tap Share, and choose Google Drive, OneDrive, or another cloud storage service you use on both phones. Upload them to the cloud, then download them on your Android phone. Alternatively, connect your iPhone to a computer, copy the photos to a folder, then transfer that folder to your Android phone via USB or cloud storage.

Messages don't transfer automatically. If you need to keep your text message history, take screenshots of important conversations on your iPhone, or use a third-party app like SMS Backup+ (Android) to back up messages to your Google account before you switch phones. Most people don't transfer messages and instead start fresh on the new phone.

Android to iPhone: moving your Google account and data

When you set up your new iPhone, you'll see a screen asking how you want to transfer data. Tap "Migrate Data from Android" and follow the prompts. Your iPhone will create a temporary connection to your old Android phone and download your contacts, calendar events, photos, and some app data. This process works best if both phones are on the same Wi-Fi network and have good battery charge.

If the automatic transfer doesn't work or you want to move data after setup, sign into your Google account on your iPhone. Go to Settings > [Your Name] > iCloud and turn on Contacts and Calendar. Then go to Settings > Mail and add your Google account. Your iPhone will sync your Google contacts and calendar events. For photos, open Google Photos on your iPhone and sign in with your Google account to access your backed-up photos.

Messages from Android don't transfer to iPhone because Apple and Google use different systems. You'll need to start fresh with messages on your new iPhone. Some third-party apps claim to transfer messages, but they're unreliable and often don't work as advertised.

What to do before you hand over your old phone

Before you start the transfer, write down your passwords for email, banking apps, and any accounts you use frequently. You'll need these on your new phone because apps don't always remember passwords during transfer. Take a screenshot of two-factor authentication settings for important accounts — some apps use codes that change, and you may need to set them up again on your new phone.

Back up your old phone one more time using its built-in backup tool (iCloud for iPhone, Google for Android). This gives you a safety net if something goes wrong during transfer. If you use a password manager like 1Password or Bitwarden, sign into it on your new phone and download your passwords there — don't rely on your phone's built-in password storage during the switch.

Check that you have access to the email address associated with your Apple ID or Google account. If you can't sign into that email on your new phone, you won't be able to download apps or access cloud backups. If you've forgotten the password, reset it on a computer before you switch phones.

Apps that don't transfer and what to do about them

Some apps won't transfer automatically, especially banking apps, payment apps, and apps that require special permissions. After your transfer completes, open your phone's app store (App Store for iPhone, Google Play for Android) and search for apps you use regularly. Download them again and sign back in with your username and password. This usually takes 15 to 30 minutes depending on how many apps you use.

Apps that use biometric login (fingerprint or face recognition) often need to be set up again on your new phone. Open the app, go to Settings, and look for a "Security" or "Biometrics" option. You'll usually need to re-enable fingerprint or face login and confirm your identity once.

If an app won't download on your new phone, check whether it's compatible with your phone's operating system and version. Some older apps only work on older versions of iOS or Android. If an app is no longer available in the app store, you may not be able to download it again — this is rare but happens when developers stop supporting an app.

Frequently Asked Questions

How long does a full phone transfer take?

A complete transfer usually takes 30 minutes to a few hours, depending on how much data you have and your internet speed. Transferring 50 GB of photos and apps takes longer than transferring 5 GB. If you're using a wireless connection, it will be slower than using a wired connection or a fast Wi-Fi network.

Will my text messages transfer to my new phone?

Text messages transfer automatically if you're switching between two iPhones or two Android phones using the built-in transfer tool. If you're switching from iPhone to Android or Android to iPhone, messages don't transfer because the systems are incompatible. You can take screenshots of important conversations or use a backup app, but most people don't bother.

What happens if the transfer fails halfway through?

If the transfer stops, restart both phones and try again. Make sure both phones are plugged in, connected to Wi-Fi, and have at least 50% battery. If it fails a second time, try transferring just your most important data (contacts and photos) manually, then download apps one at a time from the app store.

Do I need to erase my old phone after the transfer?

You don't have to, but it's a good idea before you sell or give away your old phone. 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 from the old phone so someone else can't access it.

Can I transfer my phone plan or phone number to my new phone?

Your phone number and plan are managed by your mobile carrier, not your phone. Contact your carrier (Verizon, AT&T, T-Mobile, etc.) and tell them you have a new phone. They'll activate your number on the new phone, usually within a few hours. You don't need to do anything on the phone itself — the carrier handles it.
