> Those results were a game-changer. They’re miles better than I got running the same load on the HP Envy x360 (around eight hours), the Dell XPS 13 (seven and a half hours), the Asus Zephyrus G14 (almost nine hours), and even low-power stuff like Lenovo’s Chromebook Duet (11 and a half hours) for which battery life is a major selling point. I’ll be blunt — this is the longest battery life I’ve ever seen from a laptop. It’s astonishing.

For anyone else wondering about the battery life "over 11.5 hours"

>Running through the multitasking load that I described earlier, in battery saver mode at 200 nits of brightness, the Slim 7 lasted 13 and a half hours. On the Better Battery profile, it lasted over 11 and a half hours. Remember: I was not going easy on this thing — you’ll certainly get even more juice if you’re just clicking around a tab or two.

In the T440 or so models you could have three batteries (one internal, one regular, one ultrabay) in a Thinkpad for a claimed 30 hours or so battery life with two hot-swappable batteries... :)

I have an ASUS G14 with an R7 4800HS and while nine hours are possible (at ~100% it shows exactly 10 hours), you'd have to set the brightness to a pretty low level and forget about doing anything challenging.

But six hours with your IDE open, brightness at the default level for battery mode and compiling a Node.js + TypeScript project from time to time is something you can reasonably expect to be able to do.

Currently, even though I have my charging set to max out at 80%, I don't look at the charge indicator too often because I know that I have a good few hours before it's time to plug in.

One potential note of caution is that the screen may be a contributor to that good battery life.

No it isn't. For that device, price ($300 with keyboard) is it's major selling point.
