A recent ThinkPad with one of the latest AMD Ryzen U CPUs should have a very decent battery life. You just need some custom udev rules to set the right power saving states for different devices. Powertop should make this straightforward. IMHO, this is a great compromise, because you stay on x86_64 and Linux, you get within 3/4 of ARM's power efficiency, and hardware support is perfect. I've squeezed more than 11 hours from some models.

One thing that is often discounted is that Safari is marvel of power efficiency, which adds up to the efficiency of Apple M chips. IMHO, there should be dedicated Chromium and Firefox builds with compile flags and options that optimize efficiency. To counter that, running a barebones Linux setup is a good option. Keeping your CPU wakeups/s low lets you cross the 10 hour barrier.

I use chromium based browser and applications so don't get to enjoy the benefit of the power efficiency gains of safari sadly.

Geat to know this about your experience with thinkpads. Due to your familiarity with multiple such devices would you be able to recommend a starting point for someone who wants something light with budget not being a constraint?

The new x13 Gen 6 AMD with a U-series CPU and, ideally, configured with the 70Whr battery looks very nice. Should be less than 1 kg, similar to a MacBook Air.

I've used the previous generation, and it's possible to get 10 hours of use on battery with some tweaks.

It's a very popular model, so it's well tested and everything should just work with the latest kernel.
