For users who have only used the Windows operating system all their lives, switching to Linux won't be straightforward. But it is still worth it for anyone who wants more control over the performance of their laptops or desktops. And for that, Linux already has numerous built-in tools.

While built-in tools are comprehensive and have other advantages, Linux supports a wide range of open-source utilities that can do a far better job in specific scenarios. An example of such a utility is auto-cpufreq, a popular CPU and power optimizer for Linux. And the auto-cpufreq has recently become significantly more powerful, thanks to the latest update.

The latest update to auto-cpufreq gives Linux users more control

Linux has built-in governors that can detect system load and dynamically raise or lower the CPU speed as needed. It is an excellent feature to get the best performance out of your CPU and save energy, depending on which governor you switch to. However, if you are running Linux on a Laptop and want to improve the battery life of your laptop, auto-cpufreq is a better alternative.

As the name suggests, the auto-cpufreq does optimizations automatically. It can dynamically adjust CPU frequency and governor settings to strike a balance between performance and battery efficiency.

Now, with the latest update, which takes it to version 3.0.0, the auto-cpufreq now gives Linux users more control by allowing them to override the CPU turbo setting via CLI and GUI. Also, Linux users will be able to specify the battery device in the config. This will be useful for those laptops that have multiple batteries.

In addition to these changes, the latest update to the auto-cpufreq also includes a plethora of bug fixes and improvements, which read as follows:

You can download the auto-cpufreq on your Linux system here from GitHub. However, it's worth remembering that this is designed to replace TLP, so if you have it installed, you need to remove it for the smooth functioning of the auto-cpufreq.
