Phone won't turn on: how to get your data off

A phone that will not turn on can still be holding your photos. Charge it the way the manufacturer says, force-restart it, try a computer while it half works, and stop before anything physical.

A phone that will not turn on can still be holding every photo you took with it. The safe route is short, and it belongs to the manufacturer: charge the phone properly, force-restart it, and try a computer connection while the phone half works. Stop where the official steps stop. No freezer, no heat, no opening the phone, because handling that stresses the phone's chips can cost you the data you are saving. This page is the how-to; the odds question has its own page, linked at the end.[1]

The three states of a 'dead' phone

'Dead' covers three situations, and the one you have decides how you read the result. The first is no response at all: nothing when you press buttons, nothing when you plug it in. Both manufacturers write for that phone: Apple's page is titled around an iPhone that will not turn on or shows a black screen, Samsung's around a Galaxy that will not turn on at all. The second is a phone that reaches its logo and stops, which means power is arriving but startup is not finishing. The third is a restart loop, where the phone starts, gets partway, and starts again. Charging and a force restart are worth trying in all three states.[2]

Charge it properly first, then force-restart

Most no-response phones are empty rather than broken. Apple's steps for an iPhone that will not turn on begin with power: charge it for one hour, then try again. Samsung says the same in different words for a Galaxy. The battery may be fully discharged, so use a Samsung certified charger and cable, and keep charging even if nothing appears on the screen. Samsung also documents the detail that fools people: when the battery is completely drained, the charging indicator, the lightning icon, may not appear, so silence is not proof the phone is beyond charging. One check comes before all of that on Apple's page: look over the cable and USB adapter for damage such as breakage or bent prongs, and do not use damaged accessories.[3][4][2]

Charge, then force-restart, in the manufacturer's order

  1. Check the charging cable and USB adapter for signs of damage, like breakage or bent prongs, and do not use damaged accessories.
  2. iPhone: charge for one hour, then try to turn it on. Galaxy: use a Samsung certified charger and cable, and keep charging even if nothing appears on the screen.
  3. Watch the screen while it charges. A low-charge battery icon means the phone is responding, and the guidance is to keep charging for 30 minutes or until it starts.
  4. iPhone force restart: Apple publishes a different sequence for each model family (Face ID models, iPhone 7 and 7 Plus, iPhone 6s and earlier) on one page, so use the one for your model. On the newest phones it begins by pressing and quickly releasing the volume up button.
  5. Galaxy force restart: press and hold the Power (Side) button and the Volume Down button at the same time for at least 7 seconds, then release when the Samsung logo appears and the device vibrates.
  6. If the phone still will not turn on, stop there. Apple's next step for that result is service, not more home troubleshooting, and its won't-charge page agrees: force restart covers the battery-icon case, and a device that still will not power on or charge may need service.

If it comes back: back up before anything else

If the phone responds, back it up before anything else, because a phone that came back once can go dark again, and a backup is the copy that outlives it. Apple documents two routes for an iPhone. One is iCloud over Wi-Fi. The other is a backup to a computer, which is not the same as a sync and includes almost all of your device's data and settings.[5]

Once it's back: setting up backups that survive the next time

Computer paths while the phone half-works

A phone that turns on but is unreliable may still be reachable from a computer. Apple documents that a connected iPhone should appear in the Finder on a Mac or in the Apple Devices app. Two things decide whether that happens. The cable has to carry data as well as power, and charge-only cables look exactly like data cables while being unable to expose the phone to a computer, so if nothing appears, try another cable, then another port or computer. And when the 'Trust this Computer?' alert appears, it appears on the phone, and someone has to tap Trust. That is the honest limit of this route: it needs a phone that still responds to touch.[6]

Android: the switch that had to be on already

On Android the computer path is narrower. Google's developer documentation requires USB debugging to be enabled in the phone's Developer options before tools such as adb can communicate with a device over USB. That setting lives inside the phone, so it is switched on while the phone still works. A phone that will not boot cannot switch it on now, and if it was never enabled, that route is closed. What is left at that point is the lab, not more cables.[7]

When it stays dead: the lab boundary

When charging, a force restart, and a computer connection have all come to nothing, the work left is physical, and it is not home work. A lab that does this for a living describes its dead-phone recovery as board-level work, and for very badly damaged logic boards, taking the essential chips that hold your personal data and transplanting them into a working logic board. That is what the last resort looks like: microsurgery on the phone's board, with the chips it needs intact.[1]

The line to hold: no freezer, no heat, no DIY opening. Heat and pressure stress the same chips a lab would need intact, and a lab that does this work warns there are no guarantees on long-term phone functionality due to prior stress on chips, which is its way of saying damage from earlier handling follows the phone. The manufacturers' escalation point is service too. So the home path ends where the official steps end, and a phone that stays dead goes to a professional.[1][2]
