> My 18-hour laptop is more like 8-10 hours of real work usage, which is still fantastic compared to the 2-3 hours I would get at similar tasks 6-7 years ago.

I’m not sure if you’re using an M1/2 MacBook but if you’re using windows laptops - 2 to 3 hours is pretty poor even for an old laptop (assuming it didn’t have an H series processor which is a whole another story).

My (dad’s) HP Probook with its 6th gen i5 processor could get between 6-10 hours of battery life when I got it around 2020, after some years of use. Sure, old batteries degrade, but 2-3 hours for a laptop less than 3-4 years old (or older, but with a new battery) is kinda poor to start with.

I have a fairly recent Dell XPS, maybe 2 years old. i9 and mobile RTX 3070. Realistically I get about 3-4 hours on it before it's dead. Pretty similar battery life if I'm on my linux partition too.

i get this on my macbook pro m1, but it happens when i have some webpages that suck battery life (google docs, jira etc) and/or xcode/android studio open (just sitting there) oh and corporate mandated ant-virus...

i think it might be highly dependent on work patters/environments

Never had a windows laptop that would last more than three hours...brand new or remanufactured. And I have used a LOT of windows laptops in my time, both used and new.

Except for the Lenovo Thinkpad X, or whatever they called it. I think I got ~8 solid hours of use out of them.

My 2022 MacBook Pro easily goes all day and into the evening under heavy use.

I’m comparing my experience with Macbooks with M1/M2 Max vs Dell XPS with Intel H-series and DGPUs.

Back in 2017-2019 3 hours of battery with visual studio, docker, etc. running was pretty standard for those as I remember it.
