iPhone that will not turn on does not always have a dead battery or failed logic board. Sometimes iOS has frozen while the display remains black. In other cases, the phone is running but a damaged screen cannot show an image. Charging equipment, debris in the port, an interrupted update, liquid exposure, and worn hardware can produce a similar symptom.
Start with the checks below in order. The early steps do not erase your data. Recovery mode also offers an Update option that attempts to reinstall iOS without deleting personal information. Avoid choosing Restore until you understand that it erases the iPhone.
Quick fix for an iPhone with a black screen
Try these steps first:
- Connect the iPhone to a known-working wall charger.
- Leave it charging for at least 30 minutes.
- Force restart it while it remains connected to power.
- If nothing appears, continue charging for up to one hour and try again.
- Call the iPhone or connect it to a computer to determine whether the phone is running with a failed display.
- Use recovery mode if the phone is detected but iOS will not start.
- Arrange service if it remains completely unresponsive or shows signs of physical damage.
Do not repeatedly press random button combinations. Use the correct sequence for your model and allow enough charging time before deciding that the device has failed.
First, determine what “not turning on” means
A black display can represent several different problems. Look and listen for signs of life before troubleshooting further.
The phone is completely unresponsive
There is no image, vibration, sound, charging symbol, or response when connected to a computer. Likely causes include a fully discharged battery, a charging failure, a damaged button, or an internal hardware fault.
The screen is black, but the phone rings or vibrates
If incoming calls reach the phone, alarms sound, it vibrates when connected to power, or a computer detects it, the iPhone is probably on. The display, display connector, or backlight may be faulty. Software can still cause a temporary black screen, so perform one force restart before arranging a screen inspection.
The Apple logo appears, but iOS never loads
This is a startup problem rather than a completely dead phone. An interrupted update, insufficient storage, or corrupted system software may be responsible. Recovery mode may be needed if a force restart does not help.
A battery or cable symbol appears
The battery is too low to start, or the phone is not receiving sufficient power. Keep it connected to a reliable charger and inspect the charging setup if the symbol remains for a long time.
Step 1: Charge the iPhone correctly
A deeply discharged iPhone may not respond immediately after being plugged in. Connect it to a wall outlet using a reliable cable and compatible power adapter. Wall power is generally a better first test than a low-powered USB port on a keyboard, monitor, or older computer.
Leave the device connected for at least 30 minutes. If it still does not respond, Apple recommends allowing it to charge for up to one hour before trying again.
While it charges:
- Check that the cable sits securely in the iPhone and adapter.
- Try a different wall outlet.
- Test another known-working cable and adapter if possible.
- Look for cuts, bent contacts, discoloration, or heat around the accessories.
- Remove a case if it prevents the connector from seating fully.
- Allow an extremely hot or cold iPhone to return to room temperature.
Do not assume that a cable is working because it looks undamaged. Charging accessories can fail internally.
Check the charging port safely
Use a bright light to inspect the USB-C or Lightning port. Compacted lint can prevent the connector from reaching the contacts even when it appears to be inserted.
Do not push metal tools, pins, or liquids into the port. They can damage contacts, cause a short circuit, or compact debris further. If debris cannot be removed safely without force, have the port cleaned professionally.
If the phone supports wireless charging, place it on a known-working compatible charger after removing a thick or magnetic case. A response to wireless charging but not wired charging points toward the cable, adapter, or charging port. Wireless charging is a diagnostic alternative, not proof that the port is damaged.
Step 2: Force restart the iPhone
A force restart can recover an iPhone that is powered but frozen on a black screen. It does not erase photos, apps, messages, settings, or accounts.
iPhone 8 and later, including newer iPhone SE models
- Quickly press and release Volume Up.
- Quickly press and release Volume Down.
- Press and hold only the Side button.
- Keep holding until the Apple logo appears, which can take longer than 10 seconds.
The volume-button presses must be quick and separate. If the power-off screen or Emergency SOS controls appear, release every button and repeat the sequence, holding only the Side button at the end.
iPhone 7 and iPhone 7 Plus
Press and hold the Side button and Volume Down together. Release them when the Apple logo appears.
iPhone 6s, first-generation iPhone SE, and earlier
Press and hold the Home button with the Side or Top button. Release both when the Apple logo appears.
Our dedicated how to force restart an iPhone article explains the sequence, common timing mistakes, broken-button alternatives, and the difference between restarting and resetting.
If the iPhone starts, enter its passcode. Face ID and Touch ID require a passcode after every restart, which is normal. Back up the phone once it is stable, then install pending iOS and app updates.
Step 3: Check whether only the display has failed
After charging and performing one correct force restart, test whether the phone is operating without an image.
Try the following:
- Call the iPhone from another phone.
- Move the Ring/Silent switch on a model that has one and listen or feel for feedback.
- Connect it to power and listen for a charging sound.
- Connect it to a trusted computer and check Finder, Apple Devices, or iTunes.
- In a dark room, shine a flashlight across the screen at an angle and look for a very faint image.
Do not rely on only one test. A silent iPhone may have muted sounds, disabled vibration, no network service, or a dead battery.
If it rings, vibrates, or appears on a computer while the display remains black, stop repeatedly restarting it. A damaged OLED/LCD panel, display cable, or related component may need repair. This is especially likely after a drop, screen replacement, bending, or liquid exposure.
If the screen is visible but does not respond to touch, follow iPhone touchscreen not working instead. Apple also recommends disconnecting USB-C or Lightning accessories, cleaning and drying the screen, and removing problematic cases or screen protectors when touch response is intermittent.
Step 4: Leave an overheated or very cold iPhone alone
An iPhone can temporarily stop charging or dim and disable its display outside its normal operating temperature. Move it to a dry, room-temperature location away from direct sunlight, heaters, dashboards, and freezers.
Do not cool a hot iPhone with ice, cold water, or a refrigerator. Rapid temperature changes can create condensation inside the device. Remove the case, disconnect it from power if it is unusually hot, and give it time to cool naturally.
If the phone becomes hot every time it is connected to power but never starts, disconnect it and arrange service. Unusual heat can indicate a battery, port, accessory, or internal electrical fault.
Step 5: Consider recent liquid exposure
If the black screen followed rain, a spill, submersion, or charging while the port was wet, disconnect all cables. Do not keep testing wired charging, use compressed air, insert cotton swabs, or place the phone in rice.
Keep the connector facing downward in a dry area with airflow and allow it to dry. Water resistance is not permanent and can decrease through wear or previous repairs. Liquid damage may affect the display or power system even if the exterior looks dry.
Seek professional help if the device heats up, smells unusual, shows corrosion, or remains unresponsive after drying. Do not open the phone yourself unless you have the proper training and battery-safety equipment.
Step 6: Connect the iPhone to a computer
A computer can reveal whether the iPhone is receiving power and communicating even when its display is blank.
Use:
- Finder on a Mac running macOS Catalina or later.
- Apple Devices on a current Windows PC.
- iTunes on older supported systems where applicable.
Connect the phone directly with a known-working data cable. Some inexpensive cables supply power but do not reliably transfer data. Try another USB port and avoid an unpowered hub.
If the computer recognizes the iPhone normally, create a backup if the software permits it. Recognition combined with a black display strengthens the case for a screen problem.
If the computer reports that the iPhone is in recovery mode, proceed with the Update option described below.
Step 7: Put the iPhone into recovery mode
Recovery mode is appropriate when the iPhone will not complete startup, remains at the Apple logo, displays the connect-to-computer screen, or is recognized as needing an update or restore.
Connect the iPhone to the computer and open Finder, Apple Devices, or iTunes. Then use the correct buttons:
iPhone 8 and later
Quickly press Volume Up, quickly press Volume Down, then hold the Side button. Keep holding after the Apple logo appears. Release only when the recovery-mode screen appears.
iPhone 7 and iPhone 7 Plus
Hold the Side and Volume Down buttons. Keep holding until the recovery-mode screen appears.
iPhone 6s and earlier
Hold the Home button and Side or Top button. Keep holding until the recovery-mode screen appears.
The computer should offer Update and Restore.
Choose Update first. It attempts to download and reinstall iOS while preserving personal data. Do not disconnect the iPhone during the process.
Choose Restore only if Update fails or you have decided that erasing the phone is acceptable. Restore removes the device’s data and settings before reinstalling iOS. You can recover information afterward only if a usable iCloud or computer backup exists.
If the software download takes longer than about 15 minutes and the iPhone leaves recovery mode, let the download finish. Then repeat the button sequence to re-enter recovery mode.
If the iPhone is stuck on the Apple logo
An Apple logo followed by a progress bar may be part of an update, restoration, or data transfer. Do not interrupt it just because progress is slow. Pressing a button may display an updating message and confirm that the process is still active.
Apple advises using recovery mode if the progress bar has not moved for more than one hour. Connect the phone to a computer and choose Update first.
If there is an Apple logo without a progress bar for several minutes, a force restart is reasonable. Move to recovery mode if the same screen returns and iOS never reaches the Lock Screen.
Why an iPhone may show a black screen
The symptom alone cannot identify the failed part, but common causes include:
A fully discharged or worn battery
A healthy but empty battery should respond after sufficient charging. An old, damaged, or deeply discharged battery may no longer accept enough power to start the device.
Faulty charging equipment
A failed cable, adapter, outlet, wireless charger, or power source can make the iPhone appear dead. Testing one component at a time prevents an unnecessary repair.
A blocked or damaged charging port
Lint can obstruct the connector, while corrosion or damaged contacts can prevent charging and computer communication.
A temporary iOS freeze
The phone may remain powered while the operating system stops responding. This is the scenario most likely to be solved by a force restart.
A failed display
The iPhone can ring, vibrate, and connect to a computer even though its screen shows nothing. Impact and poor-quality screen repairs are common triggers.
An interrupted update or corrupted system software
The iPhone may cycle at the Apple logo, display the recovery screen, or fail to load iOS. A recovery-mode Update is designed for this type of problem.
Internal hardware damage
Drops, liquid, battery failure, board damage, and broken internal connectors can prevent normal startup. Software steps cannot repair physical damage.
When to stop troubleshooting and get repair help
Arrange an inspection when:
- The iPhone remains unresponsive after one hour on verified charging equipment.
- It becomes abnormally hot while charging.
- The screen stays black even though the phone rings or a computer detects it.
- A required button is broken, stuck, or missing.
- The problem began after a drop, bend, repair, or liquid exposure.
- Recovery mode is unavailable or Update repeatedly fails.
- The case or screen is lifting away from the frame.
- You notice swelling, smoke, sparks, hissing, or a chemical smell.
A lifting screen can indicate a swollen lithium-ion battery. Stop using and charging the device, do not press the screen back into place, and keep it away from heat and flammable materials until a qualified repair provider can handle it.
If the data is important and no backup exists, tell the technician before authorizing a replacement, restore, or board-level work. Standard device replacement does not recover data from the original phone.
What not to do with a dead or black-screen iPhone
- Do not repeatedly trigger force restarts for hours.
- Do not select Restore before trying Update and checking your backup situation.
- Do not insert metal objects into the charging port.
- Do not use rice, ovens, hair dryers, or direct heat after liquid exposure.
- Do not continue charging a swollen, smoking, or unusually hot device.
- Do not assume the logic board is dead merely because the screen is black.
- Do not pay for a screen replacement before checking whether the phone shows any signs of life, unless physical screen damage is obvious.
After the iPhone turns back on
Once it starts normally, protect your data and look for the cause rather than treating the restart as a permanent repair.
- Back up the iPhone to iCloud or a computer.
- Install the latest compatible iOS update.
- Update recently used apps.
- Open Settings > General > iPhone Storage and create free space if storage is nearly full.
- Check Settings > Battery > Battery Health & Charging for service warnings where available.
- Observe whether the screen flickers, the phone overheats, or unexpected shutdowns return.
Recurring black screens require further diagnosis even if a force restart restores operation temporarily.
Frequently asked questions
How long should I charge a dead iPhone before trying to turn it on?
Allow at least 30 minutes on a known-working wall charger. If there is no response, Apple recommends charging for up to one hour before trying the force-restart sequence again.
Why is my iPhone screen black but the phone is still on?
iOS may be frozen, or the display may have failed. Force restart the phone once. If it still rings, vibrates, or connects to a computer without displaying an image, arrange a screen and hardware inspection.
Will a force restart erase my iPhone?
No. A force restart reboots the device without intentionally deleting personal data or settings.
Can I fix an iPhone black screen without a computer?
Charging, checking accessories, and force restarting do not require a computer. A computer becomes necessary when the phone needs a recovery-mode iOS update or restore.
Why does my iPhone show the Apple logo and then turn off?
The battery may be unable to sustain startup, the charging system may be unreliable, or iOS may be failing to load. Charge it with verified equipment, force restart it, and use recovery-mode Update if the cycle continues.
Does recovery mode erase the iPhone?
Entering recovery mode does not erase it. Selecting Update attempts to preserve data. Selecting Restore erases the device.
What if none of the buttons work?
A true force restart and recovery-mode entry require working physical buttons. If the screen is black and the required buttons are damaged, professional repair is the practical next step.
Is the black screen of death always a hardware problem?
No. A software freeze, empty battery, bad charger, interrupted update, or display fault can all cause a black screen. The charging, force-restart, computer-detection, and recovery-mode checks help narrow down the cause.
The safest order to follow
Charge the iPhone with verified equipment, force restart it once using the correct model-specific buttons, and check whether it rings or appears on a computer. If iOS will not load, use recovery mode and choose Update before Restore. Seek repair help when the device remains unresponsive, runs with no display, becomes unusually hot, or shows signs of impact, liquid, or battery swelling.
