Your iPhone screen is black and nothing responds. Before writing it off, a dead-looking iPhone is recoverable more often than not. This guide works through the fixes in order, explains what each one does, and tells you when the problem has moved past software and into hardware territory.
Quick Answer
Start with a force restart (the button sequence depends on your model). If that does not work, plug into a wall outlet using a known-good cable and wait 15 minutes. If the screen stays black after charging, try recovery mode via a Mac or PC. A persistent black screen after all three steps points to battery or logic board failure. At that point, weigh repair cost against the phone’s current used market value before spending money on a fix.
Step 1: Force Restart Your iPhone
A force restart is not the same as a standard restart. It hard-resets the device at the hardware level without erasing any data, and it can clear a software hang or crash that is keeping the screen dark. This is always the right first move.
The button sequence differs by model. Use the one that matches yours:
| iPhone Model | Force Restart Sequence |
|---|---|
| iPhone 16, 15, 14, 13, 12, 11, X, XS, XR, 8 / 8 Plus | Press and release Volume Up. Press and release Volume Down. Then press and hold the Side button until the Apple logo appears. |
| iPhone 7 / 7 Plus | Press and hold Volume Down and the Sleep/Wake button at the same time until the Apple logo appears. |
| iPhone 6s, SE (1st gen), and earlier | Press and hold the Home button and the Sleep/Wake button at the same time until the Apple logo appears. |
Hold through the full sequence even if the screen stays dark. On iPhone 8 and later, the final Side button hold can take 10 to 20 seconds before the Apple logo shows. If the logo appears, the phone is booting. Let it finish.
If the screen stays black after two or three attempts, move to step two.
Step 2: Charging and Cable Checks
A completely drained iPhone sometimes will not respond at all, not even to show the low-battery icon. The fix is simple, but the details matter.
Use a known-good cable and charger. Cables fray internally in ways you cannot see. A cable that charges fine most of the time can fail to deliver enough current to wake a fully depleted battery. If you have a second Lightning or USB-C cable, try that one.
Plug into a wall outlet, not a USB port on a laptop. Computer USB ports often deliver lower wattage than a wall adapter. A deeply drained iPhone may not respond to low-wattage input.
Wait at least 15 minutes before expecting a response. An iPhone with a critically depleted battery will show no screen activity for the first several minutes after being plugged in. Set a timer and leave it alone. After 15 minutes, try the force restart sequence again while the cable is still connected.
Check for debris in the charging port. Pocket lint packed into a Lightning or USB-C port can prevent a solid connection. Use a flashlight to look inside. A wooden toothpick or a soft brush can clear lint. Do not use metal objects.
If a charging indicator or the Apple logo appears after this, you are in good shape. If nothing happens after 30 minutes on a confirmed-working cable and charger, move to recovery mode.
iPhone Won’t Charge? Here’s How to Fix It
Step 3: Recovery Mode
Recovery mode puts your iPhone into a state where a connected Mac or PC can reinstall iOS without requiring you to unlock the device. It will not fix hardware problems, but it can resolve a corrupted iOS installation or a software failure that is preventing the phone from booting.
What you need: A Mac or Windows PC with Finder (macOS Catalina and later) or iTunes (Windows), and the cable to connect your iPhone.
How to enter recovery mode:
- Connect your iPhone to the computer.
- Open Finder (Mac) or iTunes (Windows).
- Perform the force restart sequence for your model (same as Step 1), but keep holding the final button even after the Apple logo appears. Continue holding until the recovery mode screen appears. This screen shows a cable icon pointing toward a laptop.
- In Finder or iTunes, a prompt will appear asking whether you want to Update or Restore.
Choose Update first. This reinstalls iOS without erasing your data. If Update fails or is unavailable, choose Restore. Restore erases the phone and installs a clean copy of iOS. It is the last resort on the software side, but it confirms whether software is the cause if the phone still does not respond afterward.
A successful recovery mode repair brings the phone back to the setup screen. If recovery mode fails to complete, or the phone keeps disconnecting, the problem is almost certainly hardware.
Step 4: When It Is the Battery or Logic Board
If force restart, charging, and recovery mode have all come up short, the problem is hardware. The two most common causes are a failed battery and a failed logic board. They carry different repair costs and different implications for whether repair makes sense.
Dead Battery
Lithium-ion batteries have a finite lifespan. A battery that has failed completely cannot hold enough charge to boot the phone. Battery replacement at an Apple Store or Apple Authorized Service Provider varies by model. Check current pricing at support.apple.com before assuming a figure, as Apple updates pricing periodically.
Battery replacement tends to make sense when the phone model still receives iOS updates and the rest of the device is in good condition. It is rarely worth it on an iPhone that is five or more years old.
Logic Board Failure
The logic board is the main circuit board. Failures stem from impact damage, liquid exposure, or component failure over time. Logic board repair is specialized work. Costs vary widely and often run well above battery replacement. For older models, that cost can exceed the phone’s current used market value.
A technician can usually distinguish the two failure types during a diagnostic. Apple Stores and most independent repair shops will do a basic evaluation. If the phone has a history of hard drops or liquid contact, logic board damage is the more likely cause. If it was working normally until it simply stopped booting, battery failure is more common.

Repair vs Replace: When Fixing Tech Is Worth It
Replacing a Dead iPhone with a Used One
If a diagnostic confirms the repair cost outweighs what the fix is worth, the practical move is a replacement. Buying used is the fastest way to get back to a working phone without paying new retail.
Used iPhones on Swappa are listed by verified sellers. Listings go through staff review before going live. Every listed phone must have a clean IMEI/ESN, no Activation Lock or iCloud lock, and no water damage or cracked glass. Sellers are required to disclose battery health below 80% when the Apple battery message is showing, so you know the condition before you pay.
What used iPhones cost on Swappa. Prices depend on model, storage tier, and condition, but used iPhones typically run 30 to 60% below new retail. Check the Swappa iPhone prices page for current ranges, since prices fluctuate with market demand.
A few things worth confirming before you buy:
- Unlocked vs. carrier-locked. A locked phone works on one carrier only. Unlocked models work with any compatible US carrier, including MVNOs. Unlocked vs. Carrier-Locked Phones: What It Means When Buying Used
- Battery health. Aim for 80% or higher unless the price reflects lower health. Swappa’s disclosure rule means sellers must flag anything below 80% when the Apple battery message is active.
- Condition description. Read what the seller has written about cosmetic wear. Minor scratches are cosmetic; cracked glass or Face ID that does not work are not.
Swappa’s buyer fee is a flat 3%, lower than auction-site fees. Payments run through PayPal or Stripe, both of which include buyer and seller protections and dispute resolution.
FAQ
Why won’t my iPhone turn on even when it is plugged in?
The most common causes are a fully depleted battery that needs 10 to 15 minutes on a charger before it can respond, a cable or adapter that is not delivering enough current, or a software failure that requires a force restart or recovery mode. If none of those work, the battery may have failed entirely and need replacement.
What is the difference between a black screen and an iPhone that won’t turn on?
A black screen can mean different things. If the phone shows no response to any input, it is effectively off. If the phone is on but the display is dark, you may have a display failure rather than a power failure. A useful check: if you can hear sounds, feel vibrations, or see a faint image when you tilt the screen toward a strong light, the device is on and the screen is the problem rather than power.
Can a force restart fix a black-screen iPhone?
Yes, in many cases. A force restart clears a software hang or crash that is keeping the screen dark. It does not erase data, and it works even when the screen is fully unresponsive. It is always the right first step.
How do I tell if my iPhone battery has died versus a logic board failure?
A technician with diagnostic tools can give a definitive answer. In general, if the phone had a healthy battery and no history of drops or liquid contact, battery failure is the more likely cause. If the phone took a hard impact or got wet before it stopped booting, logic board damage is more likely. Apple Stores and authorized service providers can run a diagnostic.
Is it worth repairing an iPhone that won’t turn on?
It depends on the model and the repair estimate. Battery replacement is often worth it on a phone that still receives iOS updates and has good resale value. Logic board repair at higher costs rarely makes sense on iPhones that are more than two or three years old. Get a repair estimate first, then compare it against the phone’s current used market value before deciding. The repair-vs-replace framework in the Device Care guide walks through this calculation in full.
Where can I buy a used iPhone to replace a dead one?
Swappa lists used iPhones from verified sellers with clean IMEIs, no Activation Lock, and required condition disclosures. Listings are staff-reviewed before going live. Browse current inventory and pricing at swappa.com/buy/iphones.
The Bottom Line
Most iPhones that appear dead are recoverable. A force restart clears the majority of black-screen situations in under a minute. Charging and cable issues account for most of the rest. Recovery mode handles software failures that survive both.
If all three fail, you are dealing with hardware. Get a diagnostic before committing to any repair, and weigh the cost against the phone’s current used market value. For most older models, a replacement is the better financial decision than a logic board repair.
When you are ready to replace, Swappa has verified used iPhones at 30 to 60% below new retail, with every listing staff-reviewed for clean IMEI, no Activation Lock, and accurate condition disclosures.
