"My iPhone screen is completely black and won't turn on." "It won't respond to taps, but I can still hear notification sounds." "The Apple logo appeared and then the screen went black and froze." iPhone black screens look identical from the outside, but the causes range from a dead battery or a frozen OS to an iOS bug, water damage, or a hardware failure. This guide sorts the symptoms into clear patterns and works through every fix in order: force restart, charge verification, Recovery Mode, DFU Mode, and repair decisions. There are several things worth trying before you give up, so start at the top and work your way down.

Identify your pattern: types of black screen and their causes
The right fix depends on whether — and how — the iPhone is still responding. Start by matching your situation to one of the patterns below.
Completely unresponsive — no sound, no vibration
The power button does nothing, no ringtone or notification sound plays, and there's no vibration at all. This points to a dead battery, a complete OS freeze, or a hardware failure. Plug in a charger first and see what happens.
Sound is working but the screen is black
Ringtones play, calls vibrate, you can hear tap feedback — but the display stays black. This means the iPhone itself is running; only the display output is failing. A force restart resolves this in most cases. If it doesn't, the display itself may be faulty.
Stalls after the Apple logo, or Apple logo loop
The Apple logo appears at boot but the home screen never loads, or the device cycles between the Apple logo and a black screen repeatedly. Typical causes include a failed iOS update, corrupted system files, a jailbreak gone wrong, or a storage-full condition. Recovery Mode is usually necessary.
Quick-reference table by symptom
| Symptom | Primary cause | First thing to try |
|---|---|---|
| Completely unresponsive | Dead battery / full freeze | Charge for 30+ minutes → force restart |
| Sound works but screen is black | OS freeze / display | Force restart |
| Black screen after Apple logo | iOS corruption / storage full | Restore via Recovery Mode |
| Charging indicator flashes | Deep battery drain | Keep charging for 30+ minutes |
| Just got wet | Water damage | Don't power on — dry it out and get it serviced |
Check for a dead or failing battery
A fully drained battery takes time to revive
When an iPhone battery has been completely depleted (deep discharge), connecting a charger won't wake the screen immediately. It can take anywhere from 10 to 30 minutes before the low-battery icon (battery with a lightning bolt) appears on screen.
The key is to plug in and leave it alone. Keep charging for at least 30 minutes without unplugging — repeatedly disconnecting and reconnecting actually slows the recovery. Just wait.
Isolate the cable, adapter, and port
If there's no response at all after charging, the iPhone itself may be fine and the issue may be in the charging path. Try each of these in turn:
- Swap in a different Lightning or USB-C cable (preferably Apple-certified or MFi-certified)
- Try a different power adapter (a wall outlet provides more stable power than a USB port on a computer)
- Check the iPhone's charging port for lint or debris and gently remove it with a wooden toothpick
- Try a MagSafe or Qi wireless charger as an alternative
For in-depth charging diagnostics, see How to Fix Slow iPhone Charging | Adapter, Cable, and Port Checklist.
Temperature extremes can prevent charging
iPhones are designed to charge within a range of 0–35°C (32–95°F). Outside that range, the device automatically suspends charging. If the phone was in a hot car or cold outdoor conditions just before the black screen appeared, move it to room temperature and wait before reconnecting the charger. The "iPhone needs to cool down" overlay will clear automatically once the temperature is safe.
Force restart to clear a freeze (by model)
If the battery is fine and the iPhone is making sounds, a force restart will resolve most cases. This isn't the same as a normal power-off; it hard-resets the OS state even when the device is fully unresponsive. The button sequence varies by model.
Face ID models (iPhone X and later)
Includes iPhone X, XS, XR, 11, 12, 13, 14, 15, 16 series, and Face ID iPad Pro models.
- Press and quickly release the volume up button
- Press and quickly release the volume down button
- Press and hold the side button until the Apple logo appears (10 seconds or more)
- Release when you see the Apple logo
iPhone 8, 8 Plus, and SE (2nd and 3rd generation)
- Press and quickly release the volume up button
- Press and quickly release the volume down button
- Press and hold the side button until the Apple logo appears
iPhone 7 and 7 Plus
- Press and hold the side button and volume down button simultaneously
- Release both when the Apple logo appears
iPhone 6s and earlier, original SE
- Press and hold the Home button and the side (or top) button simultaneously
- Release both when the Apple logo appears
A force restart doesn't harm the battery or erase any data. It's safe to try at any point. Complete the full sequence — if you let go before the Apple logo appears, nothing happens and you need to start over.
Could it be only the display that's not responding?
How to check whether the screen is on
Take the iPhone into a dark room and tilt it at different angles. If you can faintly make out text or the clock, only the backlight is off — the display panel itself is working. That's a milder hardware situation than a completely dead screen.
If asking Siri a question gets a spoken reply, or receiving a call produces a ring or vibration, but the screen shows absolutely nothing, the display panel or its flex cable connection may be faulty. Try a force restart; if it doesn't come back, the device needs repair.
Brightness turned all the way down
A child's curiosity or a True Tone glitch can push the brightness slider to zero. Open Control Center (swipe down from the top-right corner) and drag the brightness slider to the top. You can do this blind: swipe from the upper-right area downward, then slide upward in the brightness zone. On some devices that alone restores a visible screen.
Screen Time's Guided Access or Downtime
If Guided Access was accidentally turned on, certain interactions are blocked and the screen may appear nearly black. Triple-clicking the side button should bring up the Guided Access passcode prompt — if it does, that's your answer. Screen Time's Downtime schedule can also apply usage restrictions; check Settings → Screen Time to see what's active.
Restore iOS via Recovery Mode
When to use Recovery Mode
If force restarting doesn't help and the device is stuck in an Apple logo loop or won't boot past a black screen, Recovery Mode lets you reinstall iOS via a Mac or Windows PC. You can attempt a non-destructive "Update" first (reinstalls iOS without erasing data), and if that fails, fall back to a "Restore" (full erase and reinstall).
Step-by-step instructions
- Connect the iPhone to a Mac (Finder) or Windows PC (iTunes or Apple Devices) with a USB cable
- Enter Recovery Mode using the model-specific button sequence — it's similar to a force restart, but you keep holding until the cable-and-computer icon appears on screen instead of the Apple logo
- When the computer shows "There is a problem with the iPhone that requires it to be updated or restored," click "Update" first
- iOS re-downloads and reinstalls (15–30 minutes)
- If Update doesn't fix it, enter Recovery Mode again and choose "Restore" (this erases all data)
"Update" is the lower-risk option because it doesn't erase your data — try it first. Only choose "Restore" if Update fails. For more on the Recovery Mode button sequences and the restore process, see How to Reset a Forgotten iPhone Passcode | iOS 17/18 Recovery Steps.
DFU Mode — the deepest software recovery
When Recovery Mode isn't enough
DFU (Device Firmware Update) Mode rewrites the iPhone's firmware at a lower level than Recovery Mode. Use it only when both "Update" and "Restore" in Recovery Mode have failed to fix the black screen. DFU is a last resort because a mistake during the process can leave the device unbootable.
How to enter DFU Mode
The following sequence applies to Face ID models:
- Connect the iPhone to your PC or Mac
- Press and quickly release the volume up button
- Press and quickly release the volume down button
- Press and hold the side button for 10 seconds — the screen will go completely black
- While still holding the side button, also press and hold the volume down button for 5 seconds
- Release the side button only while continuing to hold the volume down button for another 10 seconds
- If the screen remains completely black and Finder or iTunes shows "Recovery Mode iPhone detected," you're in DFU Mode
From DFU Mode, choose "Restore" in Finder or iTunes to rewrite the firmware. A completely black screen is normal and expected during DFU Mode. If the Apple logo appears at any point, you've slipped into standard Recovery Mode — start the sequence over from the beginning.
Signs that point to a hardware cause
After water exposure or a drop
If the black screen came on immediately after getting the phone wet or dropping it, do not try to charge it or turn it on. Applying power to a wet circuit board can cause a short and permanently damage it.
- Power off immediately if possible (if not, leave it alone)
- Remove the SIM tray and wipe the exterior dry
- Leave it in a well-ventilated area to air-dry for at least 48 hours
- Do not use a hairdryer or put it in rice (heat or grain dust cause additional damage)
- Take it to Apple or an authorized service provider for inspection before attempting to power it on
A drop can dislodge the display flex cable even without visible external damage. If the screen goes black immediately after impact, that's likely what happened.
Signs of a worn-out battery
A battery nearing the end of its life can cause sudden black-screen shutdowns — the phone powers off unexpectedly, often at seemingly high battery levels. Go to Settings → Battery → Battery Health & Charging and check Maximum Capacity. If it's below 80%, or if a "Reduced performance warning" message appears, a battery replacement will likely eliminate the unexpected shutdowns.
LCD or OLED display failure
If there's audio but the screen is completely black, and a force restart doesn't help, the display itself is likely failed. This can happen without any drop history simply through age. On Face ID models, replacing the display may require recalibrating Face ID. This situation requires a repair visit.
When to get it repaired
Apple Store or Apple Authorized Service Provider
If you've worked through charging, force restart, Recovery Mode, and DFU Mode with no result, it's time for a Genius Bar appointment at an Apple Store or an Apple Authorized Service Provider. Check your AppleCare+ status first in the Apple Support app — if you're covered, screen, battery, and out-of-warranty repairs are significantly discounted.
Estimated repair costs
Reference pricing for 2026 (without AppleCare+):
- Screen repair: Starting at approximately ¥58,800 for iPhone 15 Pro Max class
- Battery replacement: Around ¥14,500
- Out-of-warranty whole-unit replacement: ¥60,000 and up depending on model (for extensive damage from drops or water)
Third-party repair shops are faster and cheaper, but non-genuine parts may trigger an "Unknown Part" warning in iOS Settings, and Face ID may stop working in some cases. AppleCare+ coverage is void after third-party repair, so if you're still covered, use the official channel first.
Back up before you hand it in
If the screen responds at all, create an iCloud or PC backup before dropping it off. If it's completely unresponsive, no backup is possible — at that point you'll need to decide whether to proceed without data recovery or pay for a separate data recovery service. The best protection is a current automatic backup from before the problem occurred. For backup options, see iPhone Backup Methods Compared | iCloud, PC, and How to Pick by Storage.
Frequently asked questions
How is this different from a "boot loop"?
A boot loop refers to the Apple logo appearing repeatedly — the device cycles between the logo and a black screen without ever reaching the home screen. The "black screen after Apple logo" pattern in this guide and a boot loop share the same causes and the same fix sequence: force restart → Recovery Mode → DFU Mode.
Lines or noise on an otherwise black screen
Vertical lines, horizontal bands, or flickering on a dark screen almost always indicate physical display panel failure — software fixes won't help. Take this as a clear signal to book a repair.
How to prevent this from happening again
- Keep iOS up to date — major bug fixes for black screen issues often arrive in point releases
- Keep at least 1 GB of free storage at all times — a full device is prone to system instability
- Replace the battery once Maximum Capacity drops below 80%
- Use only Apple-certified or MFi-certified cables and adapters
- Keep automatic iCloud backups enabled so a recent backup is always available
Summary
Here's a quick recap of the recommended fix sequence.
- Identify the pattern (completely unresponsive / sound but no display / black after Apple logo)
- Charge for at least 30 minutes to rule out a dead battery
- Perform the force restart for your specific iPhone model
- Check the obvious display causes — brightness, Guided Access, Screen Time Downtime
- If still unresponsive, use Recovery Mode — try "Update" before "Restore"
- As an absolute last resort, try DFU Mode to rewrite the firmware
- If there are hardware signs — water exposure, a drop, lines on the display — go straight to repair
- Keep iCloud backups enabled so you're covered if this happens again
Most black screens resolve at steps 3 through 5. Learning the force restart sequence for your model now means you'll have the fix at your fingertips the next time the screen goes dark.
