How long does it take to transfer data from one iPhone to another?

If you’ve bought yourself a new iPhone, you may be wondering just how long it’ll take you to get switched over to your new device.

What is the fastest transfer time between the iPhone and the new iPhone? And is there any way that I can make this transfer work a little bit faster?

These are common questions when it comes to iPhone data transfer. Here’s what you need to know about exactly how long does it take to transfer iPhone data.

Transferring iPhone data – How Long

It can take several hours to download data from your old phone and then transfer it to your new phone.

On average, this will take around 40 minutes – if there’s a small amount of data, you could be done in 10-20 minutes or even less.

However, if you have a full iPhone with 256GB of data, there’s a good chance that your transfer will be finished within 1-2 hours.

In some extreme circumstances, it may need to take 3-5 hours to complete the transfer.

There are a couple of reasons that a data transfer may take longer than expected:

  • Lots of Data: A really large data transfer may require over two hours.
  • A Slow Internet Connection: If you’re using mobile data or a weak internet connection, you may not be able to make a stable link between devices. This could result in a slower transfer than you may expect.
  • Heavy apps: If an app has a lot of data and a large amount of information to transfer, the speed may be slow.

These are the main reasons why your transfer may take two or more hours.

But in most cases, your transfer should be significantly less than 2 hours.

Why does my iPhone transfer keep failing?

Some iPhones experience migration difficulties due to data loss, which can end up with your transfer failing completely.

Direct transfer of data between the iPhones may result in some problems – here’s the best ways to fix this if your transfer keeps failing between the two iPhones.

Try a wired connection

Some users say it can take hours for data to be transferred from an old iPhone to a new iPhone using wireless connections.

Wireless is usually fine – however, when your transfer of data fails, you can connect your devices to each other via a USB cable to a wireless network.

Please ensure all your cables are properly installed and functioning when you transfer data to new iPhone.

Restart the iPhone from which you are transferring data

Sometimes the source iPhone cannot send data transfer signals to target iPhone as a result of faulty software glitch.

This can often be easily wiped out with the simple restart of the source smartphone. Then, you can start the data transfer process again from your old iPhone to your new iPhone.

Plug both your source and target iPhone into a power outlet

Something else that you can do is ensure both iPhone’s battery levels have been fully charged before starting the data transfer as it’ll stop your iPhone shutting off with battery left.

Data transmission may be delayed between phones if you don’t have full battery – you can connect both smartphones to an outlet to ensure your battery is discharged during the transfer operation.

Restore new iPhone

If you’ve turned the new iPhone on and used it in advanced, it can be a good idea to restore it back to its original iPhone settings.

Doing this will mean that you don’t need to worry about any issues on your new phone causing an issue with the transfer.


In conclusion, we’ve taken a quick look at the average amount of time is takes for iPhones to transfer data from one iOS device to another.

The factors normally influencing the amount of transfer time between iPhone are the amount of data that needs to be transferred and the method that you use to transfer data too.

So if you want to transfer data from iPhone to iPhone quicker, it’s important that you have a good connection to the internet.
