Changing an operating system is always stressful for the user, associated with the risk of losing important contacts, photos and correspondence. When you decide to switch from platform Android to iOS, the first and most logical question becomes the duration of the process. How long will you have to wait at the screen? Is it possible to interrupt migration? These questions concern everyone who holds a new iPhone and old smartphone based on Google.
The answer cannot be a single figure in minutes, since the speed directly depends on the volume of your digital life. If you store thousands of gigabytes of high-resolution photos and tens of gigabytes of video, the process will take hours. If the device only has a basic set of applications and a few documents, everything will go much faster, sometimes taking less than half an hour.
The key factor here is not only the volume of data, but also the method of transferring it. Using the official application Move to iOS via Wi-Fi Direct is a standard, but it has its own characteristics of working with large amounts of information. Understanding the technical nuances will help you plan your time correctly and avoid situations where the process freezes at 90%.
Factors influencing the speed of data migration
The time it takes to transfer information consists of many variables. The first and most obvious factor is total amount of data. The system reads each file, checks its integrity and transfers it to a new device. Photos in HEIC or JPGformat, 4K videos, music tracks - all of this has weight. The more “digital luggage,” the longer the synchronization process takes.
The second important aspect is the technical condition of both devices and the quality of the wireless connection. The application Move to iOS creates a local Wi-Fi network between phones, and any interference on the air can reduce the speed of packet transmission. The version of the operating system Android and iOSalso plays a role: on older versions of software, compression and transfer algorithms may work less efficiently.
⚠️ Attention: If your Android smartphone has a severely damaged drive or full memory (less than 10% free), the data reading speed may drop critically, which will increase the overall migration time to times.
Do not forget about the number of installed applications. Although the apps themselves often have to be downloaded again from App Store (since APK files are not compatible with iOS), the system tries to find their analogues and preserve the folder structure. This stage of searching for matches also requires time, especially if you have more than a hundred applications installed.
Average transfer time depending on volume data
So that you can roughly get your bearings, let's look at the average data transfer speeds through the app Move to iOS. The speed varies depending on the conditions, but there are certain patterns identified in practice. Below is a table showing the dependence of time on the amount of information transmitted.
| Data volume | Approximate content | Expected time | Process complexity |
|---|---|---|---|
| up to 5 GB | Contacts, SMS, some photos | 5–15 minutes | Low |
| 10–20 GB | Several thousand photos, music | 30–50 minutes | Average |
| 50–64 GB | Full gallery, 4K video | 1.5 – 2.5 hours | High |
| 128 GB or more | Full clone of device | 3 - 5 hours | Critical |
It is important to understand that the indicated time periods are relevant under ideal conditions: the proximity of the devices, the absence of other active Wi-Fi networks nearby and the serviceability of both smartphones. If you plan to transfer more than 64 GB of data, be prepared to leave the phones alone for several hours.
Why might the speed drop during the process?
The speed may decrease due to overheating of the smartphone's processor, which encrypts and transfers data. Also, background processes on Android can temporarily block the transfer channel if the system decides to perform another task as priority.
With large amounts of data (more than 100 GB), the process may appear frozen. In fact, there is intensive recording of small files, which always takes longer than the transfer of one large file of the same size. Patience at such moments, this is the best strategy.
Preparing devices for maximum speed
Before starting the procedure, it is necessary to properly prepare both devices. This will not only speed up the process, but also minimize the risk of mistakes that will force you to start all over again. First, make sure that both smartphones have at least 60% of the battery charged, or better yet, connect them to power sources.
On a device with Android you need to perform several steps. Go to your Wi-Fi settings and make sure the Smart Network Switch feature is turned off to prevent your phone from trying to find the best internet during a live stream. It is also recommended to close all background applications, freeing up RAM for the migration utility to work.
☑️ Checklist for preparing for the transfer
On the side iPhone preparation is even simpler, but more critical. The device must be reset to factory settings or be new. If the phone is already configured, you will have to erase it via Settings → General → Transfer or reset iPhone → Erase content and settings. Only on the "Hello" screen will you be able to select the option to transfer data from Android.
⚠️ Attention: iOS and Android interfaces are constantly updated. The location of menu items may vary slightly depending on the system version. If you do not find the reset point, use the search in the settings.
Step-by-step guide: transfer via Move to iOS
The main tool for migration is the official application Move to iOSdeveloped by Apple. It is available in Google Play. The process begins by selecting your language and Wi-Fi network on your new iPhone, and then selecting the “Transfer data from Android” option on the Apps & Data screen.
A six-digit or ten-digit code will appear on the iPhone screen. It must be entered on the Android device in the application Move to iOS. After entering the code, the phones will create a secure Wi-Fi network. You will be asked to select the types of data to transfer: contacts, message history, photos, accounts and free applications.
Sequence of actions:1. Launch Move to iOS on Android.
2. Click "Continue" and accept the terms.
3. Enter the code from the iPhone screen.
4. Select content to transfer.
5. Click "Continue" and do not touch the device.
After starting the process, a progress bar will appear on the Android screen. Critical important Do not switch to other applications and do not lock the smartphone screen, even if it seems that nothing is happening. Any action can break the connection, and the process will have to start again.
Place both phones on the table with their screens facing up and turn on Do Not Disturb mode on them so that incoming calls or notifications do not interrupt the data transfer process.
Typical problems and solutions
One of the most common problems is a connection error message or a sudden stop of the process at a certain percentage. This is often due to the fact that mobile data is enabled on the Android device, which conflicts with the Wi-Fi network being created. The solution is simple: completely turn off mobile data before starting the transfer.
Another common situation is getting stuck at the time estimation stage or at the last percentage. This may mean that one of the files is damaged or has a non-standard format. In such cases, the system may take a long time to read the file. If the process sits for more than 2 hours without changes, you may have to interrupt it and try to transfer the data in parts, deselecting some types of files (for example, leaving only photos and contacts).
⚠️ Attention: If the process is interrupted after 90%, do not panic. Check what data has already appeared on the iPhone. Often, the bulk of the information manages to be saved, and a restart is needed only for the remainder.
Users also encounter a problem when photos are transferred, but in low quality or not all of them. This may be due to storage optimization settings on Android or format features HEIF. Make sure your iPhone's camera settings are set to compatibility with the most compatible formats if you plan to frequently share files with your PC.
Connection stability is more important than speed. It’s better to lose 10 minutes reconnecting than to get a damaged contact database.
What to do after the transfer is complete
When the scale reaches the end, the iPhone will prompt you to complete the setup. After entering the main interface, you will find that your contacts, messages and photos are already in place. However, apps, even if found on the App Store, will likely be marked with a download icon. They require the Internet for installation, since only their “shortcuts” and settings are transferred.
Pay special attention to two-factor authentication. If you used SMS for verification codes, they will be transferred. But if you used authenticator applications (for example, Google Authenticator), they must be transferred separately through the function of exporting/importing QR codes inside the authenticator applications themselves, since the iOS security system will not allow you to simply copy this data.
Check the operation of instant messengers. For WhatsApp there is now a built-in function for transferring chat history from Android to iOS, which is activated at the very beginning of setting up the iPhone (“Transfer WhatsApp chats”). If you skipped this step, it will be impossible to restore correspondence using standard means.
Where do passwords go?
Passwords saved in Google Chrome or Android password manager will not automatically go to iCloud Keychain. You will need to either re-enter them or first export them to a CSV file and import via iCloud.com.
Alternative methods and cloud solutions
If the wired method or Wi-Fi Direct does not work, you can use cloud services. Upload photos and videos to Google Photos or Google Drive on Android, and then install the corresponding application on your iPhone and log in to your account. This is not a direct system transfer, but allows you to quickly access media files.
For contacts and calendar, just add your Google account to the iPhone settings (Settings → Mail → Accounts → Add account → Google) and enable synchronization of the required items. This method takes minutes and does not depend on the physical proximity of devices, which is convenient if the old phone is already sold or is unavailable.
However, this cannot be called a full transfer. Local files, system settings, levels in games (without cloud saves) and call history do not migrate in this way. This is more of a catch-up method than the main one.
Cloud synchronization is the best way to transfer data after the fact if the main migration process went wrong or was skipped.
How long does it take to transfer 1000 photos?
On average, transferring 1000 photos of medium quality (3-5 MB each) takes from 5 to 15 minutes depending on the speed of Wi-Fi modules in specific smartphone models. If the photo is in RAW format or 4K video, the time may increase to 30-40 minutes.
Can I interrupt the transfer and continue later?
No, the Move to iOS app does not support pause or resume functionality. If the connection is lost or you interrupt the process, you will have to start migrating data all over again from the very beginning.
Are passwords from Wi-Fi networks transferred?
Passwords from Wi-Fi networks are not transferred automatically through Move to iOS in a global sense. You'll have to re-enter your home network password on your iPhone before it remembers it. Passwords from other networks saved on Android will also need to be re-entered the first time you connect.
What should you do if Move to iOS keeps giving you an error?
Try restarting both phones. Make sure mobile data and VPN are turned off on Android. Also try disabling the "Wi-Fi Assist" or "Smart Wi-Fi" feature on Android, which may interfere with the direct connection. As a last resort, use cloud backup methods.
Do you need the Internet to work with Move to iOS?
The data transfer process itself does not require the Internet, the phones connect directly. However, if you want free versions of applications from the App Store to be immediately installed on your iPhone, Internet access must be active on your iPhone (via the same Wi-Fi network to which Android is connected, or via the mobile data if a Wi-Fi router is not used to connect phones).
