im getting pretty similar results to what it was on windows i think. endevouros kde on lenovo yoga, with tlp conservation mode when charging.

I use a 2020 hp envy 360 with a ryzen 4700u. I can get away all day typing or websurfing indoors. I can also drain the battery in two hours by playing games.

One of the things I like, is how easy it is to govern the cpu. If I know I'm away from a wall for a bit I can govern the cpu to 1.4ghz and it'll last a long time. I haven't actually done any testing to see how long.

On r/thinkpad (I think), I at some point read about the AMD powered machines having extraordinary battery life on Linux, to the degree that I regretted my very recent Intel ThinkPad purchase. Maybe that's something to search for. I think it was the new T14.

My old laptop got a new life after switching to minimalist linux instead of windows. So much longer battery time. Extended lifetime by years.

I get 10 hours of my usage on my framework. It really depends on model and your setup.

I can give you my opinion on a ~~Gigabyte~~ Clevo Laptop.

My laptop both ran to fast and hot which drained the battery. This was an issue in both Fedora and Manjaro.

I need to use different utilities to reign in the battery depending on the OS. Fedora it came out of the box but Manjaro I needed to install Slimbook Battery.

The other issue is the networking kills my sleep. Fedora was better with this than Manjaro, but newer versions of Manjaro kill WiFi when you put it to sleep. So it been better.

In comparison with windows while id like it to just work. Being able to tweak it is much preferable.

Using a Matebook running NixOS as my daily driver. Battery life is pleasingly good, lasting up to 9 hours. This without tinkering with battery settings at all.

It's around the same for me, altough windows is slightly better when battery saver is activated (hp pavilion 14 with an i7 1255u, windows 11 and fedora 38)

With mine (an Acer Aspire A515 I got for free from where my mom works) I get around 3 hours (according to the time remaining, although in longer use sessions at my desk I usually plug it in every hour or 2, and unplug it when its full), which is about the same as Windows thinks it is. So i would say it gets around the same battery life whether I use Windows or Linux

I'm sporting 8-10h on my Tuxedo Pulse 15 (Gen 1)

At least with AMD my runtime was always pretty good under Linux. Since some years at least. Was on Intel before and always had worse battery life with Linux - most probably because of the additional NVidia GPU, that didn't play nicely with Linux power management

Depends on the device. Some devices are horrible but some last for 18+ hours.

I have ~1.25hrs of uptime on Windows. Almost the same, if not more, on Arch.

It's really almost the same.
