From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How bad is battery life on Linux laptop? (lemmy.world)

I will need to get a laptop in the foreseeable future, and I really want to stick to Linux. However, I may need to be out-of-home for 12+ hours straight in a day. After some research, it seems people are generally not that impressed with battery life on Linux?

The laptop does not need to do anything heavy duty, as I will remote back into my already very beefy desktop back home.

I guess a common solution to this light use case is M2 MacBook if one wants to completely throw battery concern out of the window. Well... let's just say it's a love-hate relationship.

It depends on a few factors. Stock laptop experience with no power management software will likely result in poor battery life. You will need some kind of power management like TLP, auto-cpufreq, or powertop to handle your laptop's power management settings.

Second is the entire issue of dedicated GPUs and hybrid graphics in laptops, which can be a real issue for Linux laptops. In my own laptop with a dGPU, I am reasonably certain that the dGPU simply never turns off. I have yet to figure out a working solution for this, and so my battery life seems to be consistently worse than the Windows install dual-booted with it on the same machine.

On my Linux laptop with a Nvidia card, there is a Nvidia program which lets you switch between dedicated or on-board graphics, or on-demand where applications can request the graphics card. Before that the dedicated card was always on. I'm on mobile at the moment, but there is an official Nvidia website with drivers and other programs to control this. I assume the same for AMD, but I haven't checked.
