Any laptop with latest-generation AMD processors, efficient RAM, and an efficient SSD will work. I use an Alienware m15 r5 Ryzen edition wiht an RTX 3070 - I get around 13h of battery life on idle (low screen brightness, 60hz), and around 8-10h doing work - that means Firefox, CLion, Dolphin, and a few terminal windows open. - but compiling rather infrequently, perhaps spending 2% of my time compiling. This is with 1 NVMe SSD installed - my other NVMe SSD is quite inefficient and drops battery life. I also run KDE with a lot of blur and eye-candy enabled and a bunch of extra stuff that eats battery. If you really push battery saving to the very maximum, you can get power consumption with a similar setup at around 7W, which means a battery life of around 12 hours with a daily workload. However, as it is now, I am using between 7 and 9 watts, which results in a battery life of around 10 hours. To get this to work on Arch Linux however, it was a serious headache, took me around 9 hours of work. This seems comparable to what my friends with an M1 Pro MBP, 14", report, which is 8-9h on essentially the same workload. I get better power consumption on Windows, however, unless I fully and completely disable the dedicated GPU (I use hybrid graphics).
