How to transfer data from one iphone to another: the choice

The mechanics of how to transfer data from one iphone to another are not the difficult part. Apple’s Quick Start does it: turn on the new phone, put it next to the old one, follow the prompts. Any of the ten pages on this search will tell you that much.

What none of them tell you is that halfway through, the setup asks a question that decides the next two hours, and most people answer it in about four seconds without knowing what they have chosen.

Before either of them, three conditions have to be true or the prompt never appears at all. The current phone needs to be on Wi-Fi, Bluetooth needs to be on, and the new device needs to be near it. If the prompt shows up and then vanishes — which happens — Apple’s instruction is specific and slightly comic: restart both devices.

There is also a warning on Apple’s page that deserves more prominence than it gets, because it is the difference between a smooth evening and a stressful one: “Quick Start occupies both devices.” Not the new one. Both. For as long as it takes. So this is not a thing to begin ten minutes before leaving the house, and not a thing to begin on the only phone that can receive a verification code you are expecting.

Two more conditions on the transfer itself, both from the same page. Keep the devices near each other and plugged in to power until it finishes — this is a job for a table with a socket, not a sofa. And Quick Start needs iOS 11 or later on the device you are transferring from, which in practice means almost any iPhone still working, but not one that has been in a drawer since before that.

The exception worth knowing in advance, because it stops the whole method dead: if the new device is enrolled in Apple School Manager or Apple Business Manager, Quick Start cannot be used at all. That is a work or school phone, the restriction is deliberate, and the route in that case runs through whoever administers it rather than through anything on this page.

If the wireless transfer is slow, stalling, or simply not something you want to trust to a room full of Wi-Fi, there is a wired route — and the cable it needs is not the same cable for everyone.

That third row is the one to check before you start rather than after. Two older phones cannot be joined with an ordinary cable at all: it takes an adapter, and the adapter itself has to be plugged into power. If that is your pair, the wireless route is very probably the better plan, and the wired one is not a shortcut.

It is worth separating two things that people describe with the same words. Setting a new handset up from a backup is not the same operation as Quick Start, even though both get called transfer data from iphone to iphone. Quick Start needs the old phone switched on and beside you; a restore needs only the backup, and works when the old phone is at the bottom of a canal. They also produce different results, because a backup is a photograph of a moment and the handset is the present tense.

One last thing that this whole task quietly rests on, and that is worth settling before the new phone is even out of its box. A direct transfer copies what is on the old phone; an iCloud download copies what is in the backup. If the old phone is damaged, lost, or already wiped, only the second of those exists — which is the moment people find out how current their backup was. The floor on that sits below, and it is worth ten minutes before this becomes urgent.

The floors underneath split it four ways: the wireless method in detail, the wired one, moving from an Android phone, and what to do with the old iPhone once the new one is working.

What this tower will not do

It will not recommend a third-party transfer app. Apple ships two methods, both free, and the paid tools in this category ask for access to everything on both phones in order to do what the phones already do between themselves.

It will not pretend the two options in the middle are the same. They produce different afternoons, and which one is right depends on where you are standing.

And it will not skip the cable question. Two older iPhones cannot be connected with an ordinary cable, and finding that out at the table is worse than reading it here. What holds instead is simple: the conditions, the two transfer options and the cable requirements on this page are quoted from Apple’s own support articles, listed below with their publication dates.
