It might be due to the use of the USB-A ports on the backside of the laptop which are known to have some abnormal power draw, which framework is currently addressing.
They were talking about the usb modules. The back two on either side (the ones closest to the screen) have an issues where the USB 4 Type C to USB A adapter is not fully going to sleep when nothing is plugged in. So ArsTechnica's reviewer most likely had one of the USB A modules plugged into those two USB 4 ports which causes their apparent poor battery life.
I have a first gen framework and I really like it. Having the ports behave differently on this AMD does seem a little annoying but I guess you'd get used to it.
I think it's an alright compromise. I rarely move my expansion cards around. I use four USB-C cards and sometimes swap one out for a storage card that has Windows installed on it.
I also don't move them often, it's interesting they weren't able to get all 4 the same though. I haven't read anything that actually explains it. I guess the CPU can only handle that configuration.
My third review of this laptop is probably the one that I (and many Framework-curious PC buyers) have been the most interested to test, as the company has finally added an AMD Ryzen option to the repair-friendly portable.
I won't spend a lot of time talking about the design of the Framework Laptop 13 again, except to say that it remains a competent ultraportable, and there's nothing that feels dated or clunky about its design now that didn't already feel a little dated and clunky two years ago (the relatively thick display bezel is the main culprit here).
Another laptop in this category we generally like, Lenovo's ThinkPad X1 Carbon, has been using the same basic design for years, so it's not like Framework is in danger of falling behind in a chaotic and fast-paced industry.
All the Intel Framework Laptops have supported the same specifications for all four ports (USB 4 for the 11th-gen, Thunderbolt 4 for the newer ones), allowing you to install the expansion card modules wherever you want them without worrying about the particulars.
Framework also says the rear ports enter a "high-power mode" when USB-A modules are connected to them, which can reduce battery life.
But some modules are better fits for specific ports, and you'll have to be a bit more careful about where you put things if you want the best performance and battery life.
