Modem standby 0.3W?? I don't think CPU change alone will make these devices super-efficient.

And why is web browsing such a battery sink? Are they using an old version of edge? Is it full of random extensions??

By the way, 15 minutes into a thread about CPUs and discussion has not yet been hijacked by the fans of "that other company". Maybe HN is improving?

What are some good long battery life Windows laptops currently on market? I wouldn't need 20 hours (like macbooks have), but I'd like to get an entire work day without charging and my current experience with Windows laptops is that they last maybe 3-4 hours. Though I've also only owned mid-tier devices, so maybe that is only exclusive to top tier, not sure.
Most of the official battery life numbers you see from manufacturers are like 18 hours when the reality is less than 8 hours which is just meaningless. The numbers from reviewers using benchmarks like "modern office" might not be applicable to you, but should be relatively accurate. I would advise checking some reviews and reddit posts to see what people say.

Also note that this heavily depends on the CPU and screen configuration (LED or OLED).

One data point here: My laptop with an AMD 7840U with FHD+ IPS screen could last 9 hours in my own testing, that's without video calls or heavy multitasking. It's a ThinkPad but there are a few on the market with the same APU. A similar test on an Asus laptop with i5-1240p high-res OLED would yield 5 hours using the same method.

I know, it's annoying that there is no easy way to get a somewhat realistic estimate of the battery life on Windows laptops, while official Macbook battery life in the specs is reasonable and often accurate. Generally, you would want to get a low voltage CPU and avoid OLED screens if you want good battery life.

I had have 18hrs windows RT laptops, but those were otherwise useless.

A newer Microsoft surface gives you 13-16 hours depending on the model and HP, Dell and Lenovo have slim-ish laptopts in the 11-14 hrs range

I recently got a Framework 13 laptop and 10 hours on a charge is easily doable, especially if you put it in the low power mode. That's on Linux, but I'd assume Windows is typically smarter about conserving battery life (though maybe that's changed nowadays).

I'm incredibly happy with this laptop in general.

Look for devices with the Intel Core Ultra processor family. They’re the first Intel chips that have caught up with the M1/M2/M3 family on performance per watt.
a Lenovo Yoga Slim with a Ryzen 7840u lasts for 8-10 hours with Wifi enabled, browsing, Slack, and a text editor, with the screen brightness at around 30-40% - good enough for indoors.
LG Gram
The thing is, the previous version of Edge (before it became a re-badged Google Chrome) was quite notable for being easier on battery life, and that was marketed as an advantage for it, one which seemed to be the case in my experience.

I wish it would come back, or that there was some other web browser option for Windows (guess I should try Firefox again).
