PowerTOP Will Maximize Your Linux Laptop’s Battery Life

On Linux laptops, one of the most common complaints is that the battery life isn’t quite as good as one would hope. It’s true that with default settings, Linux gets decent battery life, but not as fine-tuned as say laptops that come with Windows. It’s easy to track your battery’s performance, but it’s more difficult to get the right settings. However, you can find out what settings are best for your system, along with various low-level statistics, through an application called PowerTOP.
