Buying a new Apple smartphone always comes with the question of preserving your digital life, as losing contacts or photos is unacceptable. Modern technology allows for full iPhone-to-iPhone syncing via Wi-Fi without the need for a computer or cables, greatly simplifying the migration process. All your data, including settings, Wi-Fi passwords, Safari history, and, of course, installed apps, can be transferred in minutes under the right conditions.
The transfer process is based on the "Quick Start" feature, which is activated automatically when the devices are brought close to each other, creating a secure tunnel for data transfer. Local Wi-Fi network In this case, it acts only as a communication channel, and the transfer itself occurs via a direct protocol between the devices, ensuring high speed and security. It's important to understand that for the transaction to complete successfully, both devices must be charged and in close proximity.
In this article, we'll detail a step-by-step process that will help you avoid common mistakes and data loss. You'll learn how to properly prepare your old and new devices, what to do if the process freezes during the time estimation stage, and how to force a resynchronization of apps. iOS 18 and earlier versions of the system provide identical tools, so the instructions are relevant for a wide range of Apple devices.
Preparing devices before starting data migration
The first and most crucial step is to check the status of both smartphones, as even the slightest software glitch can interrupt the process. Ensure that the old device is running the latest available operating system version by going to the menu. Settings → General → Software UpdateIf you plan to transfer data to a new iPhone that hasn't yet been activated, make sure it's also updated to the latest version of iOS, or update it during setup if required.
The second mandatory requirement is a stable power supply, since transferring large amounts of data via Wi-Fi Direct or a local network consumes significant battery life. Charge both devices At least 50-60% or, even better, connect them to a power source before starting the procedure. This will eliminate the risk of the smartphone suddenly shutting down at the crucial moment when system files are being written.
⚠️ Attention: Don't rely solely on the battery indicator. Even if your iPhone shows 80% charge, under heavy data transfer, the voltage may drop sharply, causing the device to go into sleep mode, which will break the connection.
You also need to enable Bluetooth and Wi-Fi on both devices, as these modules are responsible for detecting and establishing a communication channel. If Airplane Mode is enabled on your old phone or background activity is restricted, syncing won't start. Make sure recovery mode or a factory reset isn't enabled on your new device unless you plan to start from scratch.
Using Quick Start for a Full Copy
The primary method for syncing iPhone to iPhone and transferring all apps is built directly into the operating system and doesn't require any third-party software. When you turn on your new iPhone and bring it near your unlocked old device, a pop-up window will appear on the latter's screen prompting you to use your Apple ID for setup. This triggers the data transfer protocol, which will copy everything from your keyboard layout to your app accounts.
After confirming the action, an animation of chaotically moving particles will appear on the screen of the new device. This animation must be “read” using the camera of the old phone, pointing the lens at the center of the image. Visual authentication This ensures that data is transmitted to the device that's closest to you, preventing signal interception by third-party devices. If the camera can't focus, you can select "Authenticate manually" and enter the code displayed on the screen.
Next, the system will prompt you to select a data source. Select "Transfer from iPhone" to initiate a local transfer via Wi-Fi. Depending on the amount of accumulated data, the process can take anywhere from 15 minutes to several hours. During this time, the devices' screens may go dark, but interrupting the process or moving the devices far from each other is strongly discouraged.
☑️ Pre-launch check with Quick Start
It's important to note that during the transfer, apps are not physically copied in the form they're stored in memory. The system creates a list of installed apps and their settings, and then the new iPhone begins downloading the latest versions of apps from the App Store using the saved data. Internet speed It also plays a role if you did not select the option to save a full local copy before starting the process.
Alternative method: sync via iCloud
If a direct connection between devices is impossible due to technical issues or software incompatibility, you can use the iCloud cloud service. This method requires a stable and fast internet connection, as all data will first be uploaded to Apple servers and then downloaded to the new device. For full functionality, you may need to upgrade your iCloud+ storage, as the free 5GB is often insufficient for a full backup.
To create a backup on your old device, go to Settings → [Your name] → iCloud → Backup and tap "Back Up Now." Make sure all necessary items are checked in the data list, including "Photos," "Messages," and "Health Data." Once the process is complete, select "Restore from iCloud Backup" on your new iPhone during activation and sign in with the same Apple ID.
The advantage of this method is that you can start using your new phone immediately after the basic setup, while apps and photos download in the background. However, if you have many heavy games or professional apps with large caches installed, their initial download and installation may take considerable time. Synchronizing applications In this case, it happens automatically as you connect to Wi-Fi, but it requires patience.
