為什麼電池續航力不及以往使用 Windows 或 macOS 的時候?

一些電腦在換用 Linux 後,其電池續航力會不及過往使用 Windows 或 macOS 時。主要是因為電腦製造商會為 Windows 或 macOS 的電腦進行多種軟硬體的最佳化設定。這些數值調整極為精細,通常不會對外公布,也很難逆向推導,因此不會包含在 Linux 之中。

Unfortunately, there is not an easy way of applying these tweaks yourself without knowing exactly what they are. You may find that using some power-saving methods helps, though. If your computer has a variable-speed processor, you might find that changing its settings is also useful.

Another possible reason for the discrepancy is that the method of estimating battery life is different on Windows/Mac OS than on Linux. The actual battery life could be exactly the same, but the different methods give different estimates.
