I'm curious about the battery life on the X1 Carbon (and the model/specs).

I'm on an M1 Air, but over the years I've also been running (mainly) Mint on various ThinkPads and whilst I loved the experience I never got more than a few hours. And I'm now getting days with Mac OS on the Air, which is the main reason I'm using it - I have become used to not worrying about the battery life, and certainly never having to constrain performance workloads to preserve it.

So I read "Battery life is excellent" and am curious. I get that it won't be M1 (ARM) level, but for doing stuff like a mix of writing plus development (with for example smallish Go compilations) do you have a feel for any kind of averages?

I used Linux on my desktop for many years and also on and off on my laptop but since I got an M1 laptop at my previous job and since bought one for personal use, the Linux/Windows x86 laptops just can't seem to compete for my use. As you mentioned, particularly battery life is stellar on the M1.

I still find it surprising. Not the M1, but the impact the battery life has on my perceptions.

In so many ways I prefer Linux (and Windows) to the Mac. I also prefer the hardware on ThinkPads (and even my old HP ProBook) because whilst the build quality isn't there they have vastly superior keyboards, ports, and/or matte screen.

And yet it's always the Air I pick up because it's always the Air I know will launch virtually instantly and run for hours.

I consistently get 10+ hours. I'm currently using PopOS+GNOME and my typical workload is a combination of a web browser + development in terminal (vim) + Obsidian for notes + cloud sync + listening to music + IM (but not Slack ;) ). It is to say, the workload is rather low.

It is certainly not M1-like battery performance, but plenty for my average workday not to feel constrained.

My current laptop is ThinkPad X1 Carbon 7th Gen from 2019 with 1080p screen, 10th gen Intel CPU, 16GB RAM, I replaced SSD for a very fast Samsung one. The laptop has a rather tiny 51Wh battery.

Thanks - I'll bear that in mind going forward and appreciate the info. I currently have a HP ProBook of roughly the same spec (just because I quite like the keyboard and screen) but cheaper, and only get about 5 hours.

I have the IdeaPad S540 from Lenovo, and it runs Fedora 37 more or less flawlessly. Battery life is decent, I'm getting 5-7 hours out of it (light usage, 20% brightness - browsing, e-mail, some videos, office applications like LibreOffice).

I was surprised.
