why 0.80ghz
It seems your CPU drops to 0.80GHz when you disconnect the power supply. This could be due to power management settings, thermal throttling, or hardware limitations. Check the system settings or consult the manufacturer for more details.
You aim to maximize battery efficiency, so a lower processor speed is ideal. You want your laptop to last longer without overheating, avoiding draining the battery completely in an hour. Using the Windows power settings lets you pick options like "Battery saver," "Best battery life," or "Best performance." The battery saver adjusts CPU clock to at least 0.65 GHz when idle, which helps extend runtime—often adding 1 to 3 hours depending on usage—and dims the screen for better night reading. For longer battery time, it also reduces brightness compared to other settings. If you need more speed, you can switch to "Best performance," though it uses higher clock speeds and turbo mode, which is great for demanding tasks but drains power faster.
