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.

Stock android on the Pixel's have just an "Internet" button which controls both wifi and mobile data. You can press it, then it will show toggles for wifi, mobile data.
So, scrolling past marks the posts as "read" but that won't hide them. The way I do it is to use the "hide read" button in the more options menu where the settings button lives. Alternatively you can use that other setting to automatically hide all read posts, but I can't find that setting either...
I just got a pre-order for one of the Framework 16's. The issue Framework has at the moment is scale. Lenovo has the size and customer base to produce an absolute insane number of laptops compared to Frameworks operation. So cost is going to be 30, 50 or even 100% more than the big boys like Asus, Lenovo or HP. They won't ever get that scale unless people believe in it and buy one.
However, there's one other thing which I justified my purchase with. I could buy a Lenovo ThinkPad X1 Extreme with the i7-2700H, 32gb of ram and a RTX 3050ti for $AUD4,929. Or I could buy the Framework 16 with Ryzen 7840HS, 32GB ram, Radeon 7700s for $AUD3,916. Both of these processors and GPUs are similarly speced, in fact I believe the benchmarks had the Framework slightly ahead, but the framework comes out over $AUD1000 cheaper. Yes the Thinkpad X1 Extreme is their uber premium model, but just as you pay a premium for Lenovo's business grade hardware, you pay a premium for Frameworks repairability.
I believe Framework said they are looking into fixes for this issue, either with firmware patches or if neccesary a hardware revision of the USB A module. Current workaround is just to not put USB A into those two back slots.
