Here's the quick fix that works for most iPhone 14 models that won't turn on. Plug it into a wall outlet with a known-good 20W USB-C power adapter and a genuine Lightning cable. Let it charge, undisturbed, for at least an hour. After that, try the force restart: quickly press and release the Volume Up button, quickly press and release the Volume Down button, then press and hold the Side button until you see the Apple logo.
Check Your Charging Setup
If the quick fix didn't work, the issue is almost always with power. The iPhone 14 uses a Lightning port, not USB-C, so first make sure you're using the right cable. Try a different Lightning cable and a different wall charger, preferably a 20W USB-C power adapter.
Also, check the Lightning port itself. These ports are notorious for collecting pocket lint, which can block the cable from making a proper connection. Power the phone off if you can, then gently use a wooden toothpick to clear out any debris. Be very careful not to damage the delicate pins inside.
For wireless charging, try a MagSafe charger or a standard Qi pad. Make sure the phone is centered on the charger and that you've removed any thick or metal cases. If the phone feels excessively hot, unplug it and let it cool down before trying again, as MagSafe can overheat if misaligned.
Perform a Force Restart
This is different from just turning the phone off and on. A force restart clears the phone's temporary memory and can kick it out of a frozen state. It won't delete any of your data or settings.
Press and quickly release the Volume Up button. Then, press and quickly release the Volume Down button. Finally, press and hold the Side button. Keep holding it even if you see the power off slider—continue holding until you see the Apple logo appear, then you can let go.
This process can take up to 15 seconds. I've found this resolves about 80% of "black screen of death" issues on iPhones, especially if the problem started after an iOS update.
Recover Mode and Restoring with a Computer
If the screen is still black after a long charge and a force restart, you'll need a computer. Connect your iPhone 14 to a Mac or a PC with iTunes/Finder installed using your Lightning cable. Open Finder (on macOS Catalina or later) or iTunes (on older macOS or Windows).
Perform the force restart sequence again, but this time, keep holding the Side button after you see the Apple logo until you see the recovery mode screen on your iPhone. Your computer should then detect a device in recovery mode and give you the option to Update or Restore.
Always choose "Update" first. This will reinstall iOS without erasing your data. If the update fails or isn't available, you can then choose "Restore." This will install a fresh copy of iOS, but it will erase all content and settings on the phone. You'll need a recent iCloud or computer backup to get your data back afterward.
Addressing Hardware and Physical Damage
If the phone shows no signs of life at all—no vibration when connecting a charger, no brief flash of the screen, nothing—the battery or another internal component may have failed. This is less common but can happen, especially if the phone has been exposed to liquid.
Moisture can cause corrosion in the Lightning port or on internal connectors. Even if the phone dried out, the corrosion can remain and interrupt power. Similarly, a significant drop can disconnect internal battery cables.
In these cases, the solutions above likely won't work. The phone may need professional service to diagnose a faulty battery, damaged logic board, or a problematic display. Before taking it in, if you have access to another iPhone 14 or compatible model, you can try swapping known-working parts like the charger and cable to completely rule out your accessories.
