iPhone Will Not Turn On: Fixes in the Right Order

Published August 20, 2026 · Last reviewed September 2, 2026

Step 1: force restart (non-destructive, do this first)

1. Press and release Volume Up.
2. Press and release Volume Down.
3. Press and hold the Side button — and keep holding, even past the point where nothing seems to be happening.
4. Release when the Apple logo appears. This can take 15 to 20 seconds.

The two most common reasons this “does not work” are letting go of the Side button too early, and pressing the volume buttons too slowly. They must be quick presses in sequence, then a long hold. On iPhone 7 the sequence differs (hold Volume Down and Side together); on iPhone 6s and earlier it is Home and Side together.

A force restart is safe. It does not erase data, reset settings, or affect your backup. There is no reason to hesitate.

Step 2: rule out power (still non-destructive)

Action

Plug in to a known-good cable and mains adapter, and leave it for at least an hour before concluding anything.

Why it helps

A deeply discharged battery can take 15 to 30 minutes before it will even show a charging symbol, and longer before it will boot.

Verification

A charging or low-battery symbol appears on screen.

Action

Swap the cable, then the adapter, then the wall socket — one at a time.

Why it helps

Cables fail far more often than phones. Changing one variable at a time is what makes the result mean something.

Verification

One specific combination produces a charging symbol, identifying the failed part.

Action

Inspect and clean the charging port with the phone powered down, using a wooden or plastic toothpick, never metal.

Why it helps

Compacted pocket lint is one of the most common causes of a phone that will not charge, and it looks like a dead device.

Verification

A visible plug of lint comes out, and the cable then clicks in more firmly.

Action

Try wireless charging if your model supports it.

Why it helps

If wireless charging works and cable charging does not, the fault is the port, which is a repair rather than a dead phone.

Verification

The phone charges on a pad but not on a cable.

Step 3: recovery mode (choose Update, not Restore)

If the phone shows nothing after a force restart and an hour on a known-good charger, connect it to a computer. Put it into recovery mode by performing the force-restart button sequence while connected, but continuing to hold the Side button past the Apple logo until the recovery-mode screen appears.

The computer offers two options, and the difference matters enormously:

Choose Update. If the download takes more than 15 minutes the phone may exit recovery mode; simply repeat the sequence and choose Update again. Only choose Restore when Update has failed and you have accepted the data loss.

Step 4: when it is hardware

Book a repair if: the phone gets warm on the charger but never shows a screen; there is visible liquid damage; the screen shows lines, colour bands, or partial images; the phone boot-loops repeatedly after a successful recovery-mode Update; or the battery is visibly swelling and lifting the screen or back. The last one is a safety issue — stop charging it immediately.

The variant symptoms

• Apple logo loop. The phone reaches the logo and restarts, repeatedly. Force restart, then recovery-mode Update. Usually a failed update rather than hardware.
• Frozen on a screen. Force restart. Almost always software.
• Screen lights but shows nothing. Try a screenshot and see whether the phone responds with a sound; if it does, the display is the fault, not the phone.
• Works only when plugged in. The battery has failed. A replacement fixes it.

How it works

An iPhone that shows nothing is usually not off — it is stuck. A frozen process can prevent the display driver from initialising while the rest of the system still runs, which is exactly why the phone looks dead and yet a force restart revives it. That sequence is handled below the operating system, so it works even when iOS itself is unresponsive. It is the equivalent of holding a computer's power button, and it is the reason it must be tried before anything else.

The charging case has its own logic. Lithium-ion cells that discharge very deeply enter a protective state where the phone must trickle-charge for a period before it can boot at all. During that window it shows nothing, which is easily mistaken for a dead device — hence the instruction to wait an hour rather than to conclude after two minutes. Charging accessories are also the most-handled, most-flexed parts of the system, so a systematic swap of cable, adapter, and socket identifies the failure far more reliably than replacing everything at once.

Recovery mode starts a minimal bootloader that can talk to a computer without loading the full operating system. Because the storage is untouched at that point, reinstalling iOS over the top — the Update option — can repair damaged system files while leaving user data in place. Restore reformats instead, which is why the two options sit next to each other with radically different consequences and why reading the dialogue carefully matters more than speed.

Worked example

A phone that was working the previous evening shows a black screen and does not respond to taps or the Side button.

The owner's first instinct is that the battery is dead, so it goes on a charger for five minutes with no result, and the conclusion is a dead phone. That inference is wrong twice: five minutes is not long enough for a deeply discharged battery, and a stuck device would not respond to charging anyway.

The correct sequence takes ninety seconds. Volume Up press-release, Volume Down press-release, then hold the Side button. At about eight seconds nothing has happened and it feels like a failure; the owner keeps holding. At 17 seconds the Apple logo appears. The phone boots normally into iOS with every app, message, and photo intact, and the battery at 41% — confirming it was never a power problem at all.

The cause turns out to be a third-party app that had updated overnight and crashed the system process it depended on. Nothing was lost, no computer was needed, and no data-destroying step was ever reached — which is the entire argument for the order this guide is written in.
