New Phone? Keep Both Plugged In Until It Finishes

The new phone is out of the box and you have twenty minutes before you need to leave. That is the moment most transfers go wrong, and not because anything is broken.

Both manufacturers say the same thing in different words. This takes as long as it takes. Interrupting it costs you more time than waiting would have.

I could not run a transfer to show you. So every documented step below is Apple's or Google's own wording. The two of them differ on one thing, and that difference is worth knowing before you start.

The instruction both of them lead with

Read this before you unbox anything.

⚡ Documented by Apple on its Quick Start page: "Keep your devices near each other and plugged in to power until the data migration process is complete."

⭐ Near each other, and plugged in. Not in another room. Not on battery, and not while you carry one downstairs.

⚠️ Google's route starts the same way, pairing the two phones by scanning a code before anything moves.

⛔ The old phone is doing half the work. Putting it in a drawer is what breaks the transfer.

Two ways to move an iPhone, and they cost different things

Apple offers both and the difference is not obvious from the screen.

⭐ Apple describes the direct route. Transferring straight from the old device means "you'll need to wait for the transfer to complete on both devices before you can use them."

⚡ And the cloud route: "your apps and data download in the background so that you can start using your new device right away."

⚠️ So direct is slower, and complete when it ends. Cloud is usable at once. And quietly still working for hours.

⛔ Pick direct if you have the evening. Pick cloud if you need the phone now, and can accept apps arriving gradually.

Apple names who cannot use it at all

Short, and it catches people with work phones.

⚡ Apple states: "If your new device is enrolled in Apple School Manager or Apple Business, you can't use Quick Start to transfer data from your current device."

⭐ That means a company or school owned phone. The route runs through whoever manages it.

⚠️ You are not told this until you are halfway through setup. Which is why it is worth knowing now.

The Android route, in Google's words

Different mechanism, same shape.

⭐ Google's steps start at the new phone: "Turn on your new device. When prompted to set up using another device, select Android device."

⚡ Then the pairing: "Follow the instructions to scan the QR code and pair your devices."

⚠️ And a detail people do not expect. Google's next step is to "Enter your PIN, pattern, or password to transfer your Wi-Fi credentials and Google accounts."

⛔ Your saved Wi-Fi networks come across. Genuinely useful, and almost nobody knows it happens.

The one both of them handle better than their reputation

Worth its own section because people plan around it wrongly.

⭐ Google says plainly: "You can also transfer WhatsApp chats and data from your old device."

⚡ That is part of the setup flow, not a separate export. It is offered while everything else is moving.

⚠️ Ours: do it during setup or not at all. Once the new phone is in use, moving that history is a much bigger job.

⛔ And iPhone to Android is the hard direction. Google's instructions there involve a cable, and a separate check of what sits in iCloud.

⚡ Moving files between the new phone and a PC is a separate job with its own trap. One Bluetooth capability decides whether it works at all.

What never comes across

Ours, gathered from what both companies leave out.

⚡ Anything an app keeps only on the phone. Never on a server. Offline game saves, local notes, downloaded episodes.

⭐ Two-factor authenticator codes. Not unless that app has its own transfer. Move those deliberately, before you wipe the old phone.

⚠️ Anything paid for through a different store. Apps bought on one platform do not follow you across.

⛔ And your eSIM has to be moved as its own job. It is not part of a data transfer and some carriers make it awkward.

Do it in this order

Six steps, and the first one is the one people regret skipping.

⭐ Back the old phone up before you start. Google's instruction is to back up your data first, and it costs nothing to have a second copy.

⚡ Check your authenticator app has a transfer option and use it while both phones work.

⚠️ Then charge both phones and put them side by side. Give it a spare hour you are not going to need.

⛔ Do not wipe the old phone the same day. Leave it a week, with everything still on it. Things go missing quietly.

⭐ On any handover, I leave the old device untouched for a week. It has never cost me anything, and twice it has saved something.

⭐ Then check the awkward things one at a time: banking apps, the authenticator, work email, anything with a license.

⚡ And only then remove the old phone from your account and reset it. What a reset does and does not clear is worth reading first.

When the transfer stalls

Three things, in order.

⚠️ Give it far longer than feels reasonable. Both companies say times vary. A bar that has not moved for ten minutes is normal.

⭐ Keep both screens awake and both phones plugged in. A phone that sleeps or dies mid-transfer is the commonest failure.

⛔ If it genuinely fails, start setup again rather than trying to patch it. A half-finished transfer is worse than a clean second attempt.

⚡ And if apps arrive but will not open, that is a download queue rather than a failure. Give it a network and time before treating it as broken.

Status: written against Apple's and Google's own transfer documentation, 28 August 2026. ⛔ No transfer was performed here, because there was no pair of phones to run one on.

How long does transferring to a new phone take?

Longer than the twenty minutes people allow for it. Both companies say it varies with the amount of data and the connection. Apple's own instruction is to keep both devices near each other and plugged in to power until the migration is complete. That tells you it is not a quick job.

Should I transfer directly or from the cloud?

Direct if you have the evening. Apple says a direct transfer means waiting for it to complete on both devices before you can use either. The cloud route downloads in the background, so you can start using the new phone right away. Apps then arrive gradually over the next few hours.

Do my WhatsApp chats move to a new phone?

Google says WhatsApp chats and data can move across as part of the Android setup flow. Do it during setup rather than afterwards. Moving that history once the new phone is in use is a much bigger job.

What does not transfer to a new phone?

Anything stored only on the phone and never on a server. Offline game saves, downloaded episodes and notes in small apps. Two-factor authenticator codes too, unless that app has its own transfer. Your eSIM is a separate job too, and apps bought on one platform do not follow you to the other.

The Short Version

• Apple says keep both devices near each other and plugged in until it finishes.
• Direct transfer is slower but complete when it ends.
• The cloud route is usable immediately and still working for hours.
• A school or company owned iPhone cannot use Quick Start at all.
• Google's Android route moves your saved Wi-Fi networks with it.
• WhatsApp chats move during setup, and it is much harder afterwards.
• Authenticator codes and eSIMs are separate jobs you do by hand.
• Do not wipe the old phone the same day. Leave it a week.

Where to Next

Back the old phone up before you open the new box. It costs nothing and it is the step everybody regrets skipping.

Check your authenticator app for a transfer option while both phones still work. That one is genuinely painful to fix afterwards.

Then plug both in, put them side by side, and give it an hour you are not going to need.

Leave the old phone alone for a week afterwards, with everything still on it, before you reset anything.

And if something of yours did not come across that you expected to, tell me what it was in the comments. That list is more useful than either company's documentation.
