Data transfer typically takes 15 minutes to 2 hours, depending on how much you're moving and which method you use

The speed of your transfer depends on three things: the total size of your data, the transfer method you choose, and your internet connection. Moving a few gigabytes of photos and messages over Wi-Fi takes around 15 to 30 minutes. Transferring 100 gigabytes or more — especially if you're using a wired connection — can stretch to an hour or two. If you're using iCloud and your internet is slow, the process can take several hours or even continue in the background after you've started using your new phone.

The fastest method is a direct wired transfer using a USB-C cable and a Mac or Windows computer, which can move data at speeds up to 480 megabits per second. Wi-Fi transfers are slower — typically 50 to 150 megabits per second depending on your router and signal strength. iCloud transfers are the slowest because they depend entirely on your upload and download speeds, which are usually much slower than your local network.

Key Takeaways

  • Direct wired transfers using a computer are fastest, typically finishing in 15 to 45 minutes for most people's data.
  • Wi-Fi transfers between two iPhones take 30 minutes to 2 hours depending on data size and signal strength.
  • iCloud transfers can take several hours or continue in the background, and depend on your internet speed rather than the phones themselves.
  • You can use your new iPhone while a transfer is happening in the background, though performance may be slower during the process.
  • Interrupted transfers can usually be resumed from where they stopped, but some methods require you to start over.

Direct transfer between two iPhones using Wi-Fi

This is the most common method and requires both phones to be nearby with Wi-Fi enabled. During setup on your new iPhone, you'll see an option to transfer data from your old device. Place the phones close together, and the new phone will detect the old one. You'll confirm the transfer on both devices, and the process begins immediately.

For a typical user with 20 to 50 gigabytes of data, expect 30 to 90 minutes. The transfer includes your apps, photos, messages, contacts, settings, and most other data. Both phones need to stay connected to the same Wi-Fi network and remain close together — moving one phone out of range will pause the transfer. You can't use either phone during this process, so plan accordingly.

Using a computer and USB cable for the fastest transfer

Connecting your old iPhone to a Mac or Windows computer, then connecting your new iPhone to the same computer, allows you to transfer data through the computer rather than over the air. This method is significantly faster because it uses a direct wired connection instead of Wi-Fi. For most people, this takes 15 to 45 minutes.

On a Mac, use the Finder app; on Windows, use iTunes or the newer Windows version of Apple Devices. Connect your old iPhone, let it sync completely, then disconnect it and connect your new iPhone. Select "Restore from Backup" and choose the backup you just created. The computer will transfer all your data directly to the new phone without uploading to iCloud first.

iCloud backup and restore for hands-off transfers

If you don't have a computer nearby or prefer not to use one, you can back up your old iPhone to iCloud, then restore from that backup on your new phone. This method is convenient but slower because everything travels through Apple's servers. The time depends entirely on your internet speed — with a fast connection, it might take 1 to 3 hours, but with slower internet, it can take 6 hours or more.

During setup on your new iPhone, choose "Restore from iCloud Backup" and sign in with your Apple ID. The phone will download your backup and install it. You can use your new iPhone while this happens, though apps may take time to download and performance may be slower. The process continues in the background even if you close the setup screen.

What slows down transfers and how to speed them up

Wi-Fi signal strength is the biggest factor in transfer speed. If your phones are far from the router or the signal is weak, the transfer will be much slower. Move both phones closer to your router and away from other devices that might interfere with the signal. Closing other apps and stopping any downloads on either phone also helps.

For iCloud transfers, your internet upload speed is the limiting factor. You can check your speed using a speed test app or website — if your upload speed is below 5 megabits per second, iCloud transfers will be noticeably slow. Switching to a wired connection on your computer, or moving closer to your router, can improve speeds. If your internet is very slow, the computer-based wired transfer method will be dramatically faster.

Resuming a transfer that was interrupted

If your Wi-Fi connection drops during a direct iPhone-to-iPhone transfer, you'll usually need to start over. The phones will disconnect, and you'll have to begin the process again from the setup screen. To avoid this, keep both phones plugged in, stay close to your router, and avoid moving them during the transfer.

iCloud transfers are more forgiving — if your internet connection drops, the backup will resume from where it stopped when you reconnect. Computer-based transfers also resume, though the behavior depends on whether you're using Finder or iTunes. If a transfer fails repeatedly, try the computer method instead, as it's more reliable and faster.

Transferring data after initial setup

If you've already set up your new iPhone without transferring data, you can still move your information over. Go to Settings, then General, then Reset, and choose "Erase All Content and Settings." This returns the phone to its factory state, and you can then set it up again with a transfer method of your choice. This erases everything on the new phone, so only do this if you haven't added important data to it yet.

Alternatively, you can use iCloud to selectively sync certain types of data — photos, contacts, calendar, and notes — without doing a full transfer. This is slower than a complete transfer but doesn't require erasing your new phone. Go to Settings, tap your name, then iCloud, and toggle on the data types you want to sync.

Frequently Asked Questions

Can I use my new iPhone while data is transferring?

It depends on the method. During a direct Wi-Fi transfer between two iPhones, you cannot use either phone — the setup screen stays active and locks the device. With iCloud transfers, you can use your new iPhone normally, though apps may take longer to download and the phone may feel slower. Computer-based transfers also allow you to use your new phone while the transfer continues.

Why is my transfer taking so long?

The most common reasons are weak Wi-Fi signal, slow internet speed, or a large amount of data. Move closer to your router, close other apps, and check your internet speed. If you're using iCloud, your upload speed is the bottleneck — wired transfers through a computer are much faster. Very large backups (over 100 gigabytes) naturally take longer regardless of method.

What happens if I turn off my phone during a transfer?

The transfer will stop immediately. For Wi-Fi transfers, you'll need to start over. For iCloud transfers, the process will resume when you turn the phone back on and reconnect to the internet. For computer transfers, the process will resume when you reconnect the phone to the computer.

Do I need to keep my old iPhone during the transfer?

For Wi-Fi transfers, yes — both phones must be present and connected. For iCloud transfers, no — your old phone can be anywhere or even turned off, since the data is stored on Apple's servers. For computer transfers, you need the old phone connected to the computer first to create the backup, but you can then disconnect it and transfer to the new phone.

Will all my apps transfer automatically?

Your app data and settings will transfer, but the apps themselves download fresh from the App Store during or after the transfer. This usually happens automatically in the background, but large apps may take additional time. If you have many apps, the total transfer time can be longer because the phone is downloading them while also setting up your data.
