Is your iPhone 15 frozen, unresponsive, or stuck on a black screen? Don’t panic—performing a hard reset (also known as a force restart) can often solve the issue. Unlike a normal restart, a hard reset forces your iPhone to reboot, even if the screen isn’t responding to taps or button presses.
In this step-by-step guide, we’ll explain exactly how to hard reset iPhone 15, why you might need to do it, and what happens when you perform this action.
Key Takeaways
-
A hard reset (force restart) reboots your iPhone 15 without erasing your data.
-
The button sequence is: Volume Up → Volume Down → Press & Hold Side Button.
-
Use this method when your iPhone is frozen, crashing, or unresponsive.
-
Hard reset ≠ factory reset — your apps, photos, and files remain safe.
What Is a Hard Reset on iPhone 15?
A hard reset forces your iPhone to restart by cutting off power at the software level and rebooting it. It’s different from:
-
Normal Restart → Shuts down your iPhone gracefully through settings or the power slider.
-
Factory Reset → Erases all data and settings (used for selling or troubleshooting deep issues).
👉 Think of a hard reset as the digital equivalent of unplugging and plugging back in a device when it freezes.
When Should You Hard Reset Your iPhone 15?
You should try a hard reset if your iPhone 15:
-
Freezes and doesn’t respond to touch.
-
Is stuck on the Apple logo.
-
Won’t wake up from a black screen.
-
Experiences repeated app crashes.
-
Shows performance glitches that a normal restart doesn’t fix.

-
Keep holding until the Apple logo appears.
