Getting a new iPhone is exciting, but moving all your important data from your old iPhone to the new one can feel complicated. You may want to transfer photos, videos, contacts, messages, apps, settings, and other personal files without losing anything.
In this compelete guide, we will introduce how to transfer data from iPhone to iPhone with step-by-step instructions, help you choose the most suitable way, and fix common problems when iPhone transfer does not work. Let's jump in.

iPhone to iPhone data transfer can be easy if you do it right. Before starting the transfer process, it is important to prepare both your old and new iPhone. Proper preparation can help prevent common problems, such as transfer failures, slow migration speeds, or insufficient storage.
First, before the transfer, you can check whether your new iPhone has enough storage space for the data from your old device. On your old iPhone, you can go to Settings > General > iPhone Storage. Review how much storage your current data uses, including photos, videos, apps, and documents. If your old iPhone contains more data than your new iPhone can hold, you may need to free up some space and remove unnecessary files before transferring.
💡 Tips: Use Syncios Mobile Manager to delete, edit, and manage your iPhone data selectively.

In case of any data loss, backing up your old iPhone is necessary. Tools like iCloud Backup, Finder, iTunes, and Syncios Mobile Manager can make a reliable backup.
Make sure both iPhones are running compatible iOS versions. Updating your iPhone before migration can reduce transfer problems. You can check for updates in Settings > General > Software Update. Tap "Update Now" if any.
Large data transfers can take a long time, especially if you have many photos and videos. It is highly recommended to keep both devices connected to power throughout the process to avoid interruptions.
Some transfer methods require your Apple Account password to restore backups, download apps, or activate certain services. Make sure you know your Apple Account credentials before starting.

Speaking of how to transfer data from iPhone to iPhone, Apple's official solution, Quick Start, is always the first considerable option. It is designed specifically for users who are setting up a new iOS device and want to move their existing content quickly. With Quick Start, you can transfer many types of data, including photos, videos, contacts, messages, apps, device settings and more.



The transfer time depends on how much data you have. If your old iPhone contains a large number of photos, videos, or apps, the process may take longer.

* Note: During setup, Quick Start may offer two different ways to move your data. You can choose to transfer directly from your old iPhone or download your information from iCloud. Direct transfer is usually better when you still have access to your old iPhone, both devices are available at the same time, and you want to move data without relying on internet speed.
iCloud is another official way to move your data to a new iPhone. This method is especially useful when your old iPhone is unavailable or when you already have a recent iCloud backup. Before restoring your new iPhone, you need to create a backup from your old device. You can go to Settings > Apple Account > iCloud > iCloud Backup > Back Up Now.
After your backup is complete:

If you prefer transferring your iPhone data through a computer, you can use Apple's computer backup solutions. This method creates a local backup of your old iPhone and then restores that backup to your new device.
NOTE: If you have already set up your new iPhone, you need to erase it to proceed. Don't want to erase data on your new iPhone? Try Syncios Data Transfer to move all or selected data between iPhones without data deletion.

Compared with Quick Start, this method requires a computer. If you already keep local iPhone backups, or your internet connection is slow, or you want to keep a backup file on your computer, or you prefer transferring data without relying on cloud storage, this computer transfer is useful for you.
We know that Apple's own transfer methods are mainly designed for complete device migration. However, what if you have already set up your new iPhone and used it for a while? What if you want more control over the iPhone data? That's where Syncios helps, especially when you only need to transfer specific files instead of moving everything at once.
Syncios Data Transfer lets you transfer various types of data between iPhones, including contacts, messages, videos, photos, music, call logs, apps, bookmarks, ebooks, notes, calendars, Safari history, voicemail, WhatsApp, LINE and more. Just a few clicks and all your data is transferred, with all data intact on your target phone. No erase.
The best part is that you can choose which data type you would like to move. Not all, but selectively. It is not only used for the new migration, but for data transfer any time. Besides, it allows you to backup your iPhone data to a computer and restore it to another device. Backup whenever you want to prevent data loss.
So Syncios Data Transfer can provide more flexibility. Unlike Apple's method, which is designed mainly for setting up a new iPhone, Syncios focuses more on giving users control over individual types of data.



Syncios Data Transfer gives you the flexibility to transfer what you want between phones. But some users still ask what if they want to transfer or backup a couple of photos, music, contacts, etc.? We recommend Syncios Mobile Manager.
Which music, which photo, which album, which apps would you like to backup or transfer? You can preview clearly inside the program. Export, import, edit, delete and perform more operations with Syncios Mobile Manager.

AirDrop is another convenient way to send files between iPhones. Although it's limited, it allows you to quickly share photos, videos, documents, and other supported files wirelessly.

NOTE: AirDrop is not a complete iPhone-to-iPhone transfer method. It cannot transfer Apps, System settings, Messages, Complete backups, Most app data. Therefore, AirDrop is suitable for transferring a few files, but it is not recommended when you are moving everything from an old iPhone to a new iPhone.
Although transferring data from iPhone to iPhone is usually straightforward, you may still encounter problems during the process. Below are common issues and solutions.
If the Quick Start prompt does not appear on your old iPhone, try the following solutions.
The transfer time depends on the amount of data being moved, the number of photos and videos, network conditions, device performance. For example, transferring several hundred gigabytes of photos and videos may take much longer than transferring only contacts and messages. So to improve transfer speed, you can:
If your new iPhone does not have enough storage space, the transfer may stop or fail. Before transferring, check Settings > General > iPhone Storage. Here are ossible solutions.
👉 If you do not need a full device migration, transferring selected files with Syncios Data Transfer may be a better option.
If your iPhone transfer fails during the setup process, try these steps:
Yes. If you want to perform a complete migration using Apple's official methods, you may need to erase the new iPhone and restart the setup process.
To erase your iPhone, go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings. Before doing this, make sure you backup any important information on your new iPhone. If you only need to move specific files, Syncios Data Transfer may allow you to transfer selected content without resetting the device.
The easiest way is to use Quick Start. Place your old and new iPhone close together, follow the on-screen instructions, and choose the direct transfer option. If you cannot access your old iPhone, you can restore your new device from an iCloud backup or a computer backup.
There is no fixed answer. For most users, Quick Start may be the fastest and simplest option. But you should know that the actual transfer speed depends on the data size, transfer method, internet speed, device performance and more. A small amount of data may finish within a short period, while transferring a large photo and video library can take much longer.
Most personal data can be transferred, but some information requires additional setup after moving to the new iPhone, including Apple Pay cards, Face ID or Touch ID settings, some apps, certain downloaded content and more. If you want to know what data can be transferred, please check this table.
If you still have your old iPhone, direct transfer is usually the better choice because you can move data directly between devices. iCloud is more convenient if your old iPhone is unavailable, you already have a recent backup, or you just prefer restoring from the cloud.
Yes. You can transfer data without iCloud by using Quick Start direct transfer or Syncios Data Transfer.
Yes, if you use Quick Start direct transfer. A separate backup is not required because the data is transferred directly from the old iPhone to the new one. However, creating a backup before migration is still recommended in case something goes wrong.
If your new iPhone has already been set up, some Apple migration methods require you to erase the device before starting a complete transfer. If you want to transfer data from iPhone to iPhone without resetting, use Syncios Data Transfer.
Quick Start is the most recommended method because it is simple, built into iOS, and designed specifically for moving data to a new iPhone. Syncios Data Transfer is also best if you have already set up your iPhone or want to move data selectively. However, the best method depends on your situation.
How to transfer data from iPhone to iPhone? Which method should I choose? If you are still struggling, this ultimate guide has everything you need. Apple's official methods let you transfer the entire device, while Syncios Data Transfer also offers you a reliable and flexible way to transfer specific data types.
