FORCE RESTART IPHONE 15


Step One


Press and quickly release the Volume Up button on your iPhone 15, then press and quickly release the Volume Down button. The volume buttons are located on the left side of your device.

Important Notes


If you accidentally activate Siri while attempting these steps, it's likely you've waited too long between a button press. Watch our video on how to force restart to get a better idea of the timing.

What Does a Force Restart Do?


When you force restart an iPhone, it triggers a hardware reboot of the device. This means that the operating system (iOS) is not shut down gracefully, but rather the power to the hardware is cycled.

Here's what happens during a force restart:
● Power Cycling: The process immediately cuts off power to the CPU and memory, which clears the current state of the software.

● Memory Flush: Any data stored in volatile memory (RAM) is cleared. This means any unsaved data or operations that were in progress are lost.

● Hardware Reset: The hardware registers and system controllers are reset to their default state. This can resolve issues where the device is unresponsive due to a hardware component not acting as expected.

● System Check: Upon restart, the device performs a basic system check to ensure that the hardware is functioning correctly.

● Operating System Reload: The device's bootloader starts up, and the operating system is reloaded from the non-volatile memory, like a fresh boot.

A force restart is generally used as a troubleshooting step when the iPhone is frozen, unresponsive, or encountering a severe software issue that prevents normal operation. It's a way to get the device working again when the standard methods of interaction are not effective. It does not erase the content of the device or affect the firmware; those kinds of resets are achieved through different processes.
