Which version of Linux offers the best battery life for Intel e-core owners?

I have read a few articles now talking about well optimized Linux has become at using e-cores to conserve battery life on laptops, and I was wondering does it matter which version of Linux? or do you just need to be on like Linux Kernel 6.5 or newer to get those benefits?

Yeah for the most part. But thankfully I think all the current LTS distros even slow ones like mint have upgraded by now? Shit I think even debian stable is on 6.1. 6 being the big leap in new hardware compatibility.

For e-cores specifically Intel and AMD are both pushing tons of patches you can see some intel specific stuff here:


but specifically especially for meteor lake and up you want to be on 6.5 and up. They are both still pushing a lot of architectural changes for both current 6.10-rc and the coming 6.11 cycle. At least for the NEW archs, it remains to be seen if they have a massive effect on the older archs but battery life is pretty good already.

Not only the kernel plays a role, but several factors play a role in this area.
You can see that your CPU/GPU usage is as close to 0% as possible when the system is idle.

For example, xmonad will probably draw less CPU/GPU power than KDE Plasma and Gnome.

The best method to see which system configuration draws the least power on your laptop is via an energy meter.
You simply take the battery out of the laptop and then you see how much power the laptop draws in idle status with all apps closed.

ELV Energy Master Profi II is a very accurate energy meter at lower loads.

mods you can close this thread, I just realized I can never use Linux for work when I travel. my company informed me I have to use their proprietary VPN from Cisco networking or w.e that company is called, its custom one just for my company, and it has no Linux option that I can see.

lol well, that was a huge waste of time. sorry everyone.

Does it happen to be Cisco AnyConnect? If so... https://intercom.help/privatevpn/en/articles/6385644-anyconnect-setup-guide-for-fedora-linux

I don't need to mess with it just yet, but i bookmarked this thanks

I had to use the same VPN and it worked out of the box for me with Fedora.
