Yes, this is the true dividing factor for me. The battery life of the new ARM laptops is an astounding upgrade from any device I have ever used.
I've been a reluctant MacBook user for 15 years now thanks to it being the de-facto hardware of tech, but for the first time ever since adopting first the M1 Pro and then an M2 Pro I find myself thinking: I could not possibly justify buying literally any other laptop so long as this standard exists.
Being able to run serious developer workflows silently (full kubernetes clusters, compilers, VSCode, multitudes of corpo office suite products etc), for multiple days at a time on a single charge is baffling. And if I leave it closed for a week at 80% battery, not only does that percentage remain nearly the same when resumed-- it wakes instantly! No hibernation wake time shenanigans. The only class of device which even comes close to being comparable are high end e-ink readers, and an e-ink reader STILL loses on wake time by comparison.
I'm at the point now where I'm desperately in need of an upgrade for my 8 year old personal laptop, but I'm holding off indefinitely until I discover something with a similar level of battery performance that can run Linux. As I understand it, the firmware that supports that insane battery life and specifically the suspend functionality that allows it to draw nearly zero power when closed isn't supported by any Linux distro or I would have already purchased another MacBook for personal use.
I am running Sway on a Gentoo on a 4 years old X1 carbon.
> you will get similar usable battery life of around 6-8 hours
My macbook M3 gives me way more than 6-8 hours, it's simply insane. It literallly lasts for multiple days.
> Generally though, battery life isn't an issue anymore considering fast charging is everywhere.
Not an issue indeed, I got used to always charging my X1 carbon. But then I got an M3 for work, and... well it feels like I don't have to charge it ever :-).
As I said: very much a Linux person, but the M3 battery life is absolutely insane.
I am very much a Linux person. But the battery life with macOS on the Apple Silicon is absolutely insane.
