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

Moving data from one phone to another usually takes 15 minutes to an hour, depending on how much you have and which phones you own. If both phones are the same type — iPhone to iPhone, or Android to Android — the built-in transfer tools are fastest and most reliable. If you're switching between types, you'll use cloud services or a computer to move your data in pieces.

The three main routes are: using your phone's built-in transfer tool (fastest if available), backing up to a cloud service and restoring on the new phone (works across phone types), or manually moving specific data like photos and contacts. Which one you use depends on whether you're keeping the same operating system and how much data you have.

Key Takeaways

  • iPhone to iPhone and Android to Android transfers use built-in tools that move almost everything in one step, usually taking 30 minutes to an hour depending on data size.
  • Switching between iPhone and Android requires using cloud services like Google Drive, iCloud, or OneDrive to move data in separate categories rather than all at once.
  • Photos, videos, and large files transfer fastest over Wi-Fi; cellular networks are slower and may pause if your signal drops.
  • Contacts, calendars, and email settings can be moved separately using your email account or a cloud backup, even if you don't move everything else.
  • Keep your old phone powered on and nearby during the transfer in case you need to re-enter passwords or verify accounts on the new phone.

iPhone to iPhone: Using Quick Start

If you're moving from one iPhone to another, Apple's Quick Start tool moves almost everything automatically. Turn on your new iPhone and hold it near your old one. Your old phone will show a setup screen; tap it to start the transfer. The new phone will display an animation — point your old phone's camera at it to connect the two devices.

Quick Start transfers your Apple ID, Wi-Fi passwords, Face ID or Touch ID settings, home screen layout, installed apps, photos, messages, mail, contacts, calendars, and health data. The process takes 30 minutes to several hours depending on how much data you have. Keep both phones plugged in and on the same Wi-Fi network during the transfer. Do not unplug either phone or move them far apart until the progress bar finishes.

If Quick Start doesn't work — for example, if your old phone is too old or damaged — you can restore from an iCloud backup instead. On your new iPhone, go to Settings > General > Transfer or Reset, then choose Restore from iCloud Backup. Sign in with your Apple ID and select which backup to restore. This takes longer than Quick Start but moves the same data.

Android to Android: Using Google Account or Samsung Smart Switch

For Android phones, the method depends on whether both phones are Samsung or one is a different brand. If both are Samsung, use Samsung Smart Switch. Open Smart Switch on your new phone, choose Receive Data, then select Wireless. On your old phone, open Smart Switch, choose Send Data, and scan the code shown on the new phone. The phones will connect and begin transferring contacts, messages, photos, videos, apps, and settings.

If you're moving between different Android brands — for example, from a Google Pixel to a OnePlus — use your Google Account instead. During setup on your new phone, sign in with the same Google Account you used on your old phone. Android will automatically restore your contacts, calendar, Gmail, Google Photos, and installed apps from Google Play. This usually takes 15 to 30 minutes. Some apps may need to read again, and you may need to re-enter passwords for apps that don't store login information in your Google Account.

For data that Google Account doesn't cover — like text messages, call logs, or files stored locally on your old phone — you can use a third-party tool like Samsung Smart Switch (which works on non-Samsung phones too) or Google Takeout to read your data and move it manually. These options take longer but give you more control over what moves.

iPhone to Android or Android to iPhone: Using Cloud Services

Switching between operating systems requires moving data in separate pieces because iPhone and Android don't have a single built-in transfer tool that works both ways. The most reliable method is to use cloud services you already have access to.

For contacts and calendar, sign into your Google Account on your iPhone (Settings > Mail > Accounts > Add Account), or sign into your iCloud account on your Android phone (Settings > Accounts > Add Account). Your contacts and calendar will sync automatically to the new phone within a few minutes. For photos and videos, use Google Photos on iPhone or iCloud Photos on Android — both let you upload your library to the cloud and read it on the other phone type. This works best over Wi-Fi and may take several hours if you have thousands of photos.

For email, add your email account to the new phone's mail app. Go to Settings > Mail > Accounts > Add Account, enter your email address and password, and the new phone will read your recent messages and sync future ones. Text messages don't transfer between iPhone and Android through any automatic method — you'll need to screenshot important conversations or use a third-party app like Google Messages or Samsung Messages that can back up texts to the cloud.

Moving specific data types manually

If you only need to move certain things — like photos, documents, or a specific app's data — you can do it without transferring everything. Connect your old phone to a computer using a USB cable and copy files to a folder. Then connect your new phone and copy the files to it. This works for photos, videos, PDFs, and other files stored in your phone's main storage.

For app data like notes, to-do lists, or banking information, check whether the app has its own backup or cloud sync feature. Open the app on your old phone, look for Settings or Backup, and see if you can save your data to the cloud or export it as a file. Then sign into the same app on your new phone and restore from that backup. Apps like Evernote, Microsoft OneNote, and most banking apps have this built in.

For passwords, use your phone's built-in password manager. On iPhone, passwords are stored in iCloud Keychain; on Android, they're stored in Google Password Manager. If you sign into your Apple ID or Google Account on your new phone, these passwords will sync automatically. If you use a third-party password manager like 1Password or Bitwarden, sign into it on your new phone and your passwords will read.

What to do if the transfer stalls or fails

If your transfer stops partway through, the most common causes are a weak Wi-Fi connection, a phone running out of battery, or an account that needs re-authentication. Check that both phones are still connected to Wi-Fi and plugged in. If the transfer is still stuck after 10 minutes, restart both phones and try again.

If you get an error message about your Apple ID or Google Account, it usually means the account needs to verify your identity. On the new phone, go to Settings and sign out of the account, then sign back in. You may be asked to enter a verification code sent to your email or phone number. Complete this step and try the transfer again.

If a specific app won't transfer, it may not be available in your new phone's app store, or it may require a separate purchase. Open the app store on your new phone and search for the app by name. If it's not there, check whether the developer has discontinued it or released a newer version under a different name. For paid apps, you usually won't be charged again if you're using the same account.

Timing and what to expect during the transfer

Built-in transfers like Quick Start or Smart Switch usually take 30 minutes to 2 hours depending on how much data you have. Cloud-based transfers like iCloud or Google Account sync take longer — sometimes several hours if you have a large photo library or many apps. During the transfer, keep both phones on Wi-Fi, plugged in, and in the same room. Do not use either phone or put it to sleep.

After the transfer finishes, check that your most important data arrived: open your contacts, calendar, email, and photo app to confirm. Some apps may take a few extra minutes to read and install. If an app didn't transfer, you can read it again from the app store. Passwords and login information usually transfer automatically, but you may need to re-enter passwords for apps that don't use your main account (like banking apps or social media).

Frequently Asked Questions

Can I transfer data if my old phone won't turn on?

If your old phone is completely dead, you can only recover data if you previously backed it up to iCloud (iPhone) or Google Account (Android). If you have a backup, you can restore it on your new phone during setup. If you don't have a backup, data stored only on the old phone cannot be recovered. This is why backing up regularly is important.

Will my apps transfer to the new phone?

Most apps transfer automatically if you use Quick Start, Smart Switch, or sign into your Google Account or Apple ID on the new phone. The app store will re-read them. However, some apps may not be available in your new phone's app store, or they may require a separate purchase if you're switching between iPhone and Android. You won't be charged twice for paid apps if you use the same account.

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

You should keep your old phone powered on for at least a few hours after the transfer in case you need to re-enter a password or verify an account on the new phone. After that, you can turn it off. Before you sell or recycle it, erase all data by going to Settings > Reset or Settings > Erase All Data to make sure your personal information isn't left on the device.

What if I'm only transferring some data, not everything?

You can move specific items like contacts, photos, or email without transferring everything else. Sign into your cloud account (Google, iCloud, or Outlook) on the new phone and only sync the categories you want. For photos, use Google Photos or iCloud Photos. For contacts and calendar, add your email account to the new phone's settings. This gives you more control but takes longer than a full transfer.

Can I transfer data over cellular instead of Wi-Fi?

Cellular networks are much slower and less reliable for large transfers. If you must use cellular, keep your phone plugged in and expect the transfer to take several hours. Wi-Fi is always faster and safer because the connection is more stable. If you don't have Wi-Fi at home, consider doing the transfer at a coffee shop or library with public Wi-Fi.
