A hard reboot is restarting your device after completely switching its power off. A manual hard reboot restarts an unresponsive device and erases its working memory (RAM).

However, this action can delete all of your unsaved data. Not all hard restarts are deliberate; for instance, a power outage can force the device to shut down.

Hard Reboot vs. Soft Reboot

Executing a hard reboot can remove unsaved data. So, you should only do it as the last resort when your device becomes completely unresponsive. In all other circumstances, you should perform a soft restart, allowing the device to reboot without shutting down the power. Doing a soft reboot from the interface of your OS allows the gadget to save all your data before a restart.
