How to Force Restart an iPhone Across Every Generation

Few moments in modern life inspire mild panic quite like a black, unhelpful smartphone screen. You tap the display, press the power button, and flip the mute switch, but nothing happens. Your device is completely frozen. Before you schedule an expensive service appointment or assume the worst about your battery, there is a built-in hardware key combination designed specifically for this scenario. Learning how to force restart an iPhone cuts power directly at the hardware level, bypassing software glitches and waking your phone from a frozen state without erasing your personal data.

Modern Devices: iPhone 8, iPhone SE (2nd/3rd Gen), and Face ID Models

Apple introduced a unified key sequence starting with the iPhone 8 and continuing through the iPhone 16 lineup. Because modern devices lack physical home buttons, this process relies entirely on precise timing across the volume and side buttons.

1. Press and quickly release the Volume Up button.
2. Press and quickly release the Volume Down button.
3. Press and hold the Side button (power button) until the screen turns black and the Apple logo appears.

Do not let go of the side button when you see the shutdown slider; keep holding it until the screen goes dark and the white Apple logo flashes.

Legacy Models: iPhone 7, iPhone 7 Plus, and Older Generations

If you are carrying an older device, Apple used dedicated physical inputs for hardware resets. Because these models feature different mechanical architectures, the button combinations vary.

iPhone 7 and iPhone 7 Plus

The iPhone 7 replaced the mechanical click button with a solid-state haptic engine, requiring a unique combination to force reboot.

• Press and hold both the Volume Down button and the Sleep/Wake (Side) button simultaneously.
• Keep holding both buttons for roughly 10 seconds until the screen turns black and the Apple logo displays.

iPhone 6s, iPhone SE (1st Gen), and Earlier

Legacy devices with physical home buttons rely on the classic two-button combination that original iOS users remember well.

• Press and hold both the Home button and the Top (or Side) button at the exact same time.
• Hold both inputs together until the screen clears and the Apple logo signals a reboot.

What to Do If Your iPhone Still Will Not Turn On

If executed correctly, attempting to force restart an iPhone will resolve roughly nine out of ten software freezes. However, if your display remains completely black or stuck on a loop, hardware or power delivery issues might be at play.

First, connect your device to a verified charger using an original cable and let it sit undisturbed for at least thirty minutes. Sometimes a depleted battery enters a deep-discharge recovery state that prevents immediate boot sequences. If charging yields no results, plug the device into a computer running Finder or iTunes to check if the system recognizes it in recovery mode.
