Start with what you see
Let the result choose the next step
Quick Start prompt disappeared
Restart both devices, keep Wi-Fi and Bluetooth on, and place them together.
Discovery ended before the migration was established.New phone usable but apps still loading
Check whether iCloud download was selected and keep power and Wi-Fi connected.
Background restoration may still be working normally.Both phones remain occupied
Confirm direct transfer mode and allow time based on data size and network conditions.
Direct transfer is not designed for simultaneous phone use.Critical data absent after completion
Keep the old phone intact and verify account, backup, sync, and app-specific migration state.
Do not erase the remaining good copy.
Step 1
Identify the transfer mode
Read the new device status: direct transfer requires both devices until it finishes; iCloud download allows earlier use while content continues in the background.
Background app downloads can look incomplete even after setup has successfully finished.
Step 2
Stabilize power, proximity, and wireless
Keep devices near each other and plugged in, connect the old device to Wi-Fi, enable Bluetooth, and avoid using either device during direct transfer.
Apple requires proximity and power and notes transfer time varies with network conditions and data size.
Quick Start nearby-device discovery screen
Apple’s Quick Start screen is still in discovery: it asks for the current device to be nearby and confirms Bluetooth as a prerequisite.
If setup remains on this exact screen, check proximity, Bluetooth, Wi-Fi, and the old-device prompt before deciding data transfer is stalled.
Model scope
iOS Quick Start discovery represented by Apple’s iOS 17 example; wording and appearance can change in later releases.
Step 3
Restart only when setup has not begun
If the Quick Start prompt disappeared from the old device before transfer, restart both devices and place them together again.
Apple specifically recommends restarting both when the setup prompt vanishes.
Step 4
Use wired transfer when wireless stays unreliable
If wireless conditions remain unreliable, use Apple’s documented cable and adapter combination for the exact source and destination connector types.
A wired migration can remove local wireless transfer variability without changing the data source.
Step 5
Verify before releasing the old phone
Check photos, messages, contacts, notes, authenticator access, eSIM or SIM service, banking apps, health data, and pending app downloads.
A completed setup screen does not prove every cloud item, credential, or cellular service has arrived.
Scope and limits
Before you apply this advice
This covers: Personal iPhone and iPad migrations using Apple Quick Start over wireless or an Apple-documented wired connection.
This does not cover: Apple School Manager or Apple Business enrolled devices, account-recovery delays, unsupported third-party transfer apps, or bypassing activation security.
- Do not erase, reset, sell, or trade in the old device until critical data and authentication are verified.
- Do not interrupt a progressing direct transfer solely because its estimate changes.
- Contact Apple when activation, account security, or repeated supported transfer attempts prevent setup from completing.
