On Linux this was solved for me by using `tlp` and I check usage once in a while with powertop. It's going to be not so great out of the box (~5-6 hours) but after some basic tweaks I can pull 10. Mostly the fixes are about getting the CPU to scale down into a low power state.
Running Fedora and doing web browsing + light coding, I get around 5 hours of battery. That doesn't feel great, but it's rarely an actual problem for my use patterns.
I've never managed to get sleep or hibernate to work correctly, so aside from the fact that I have to shut the thing all the way down if I want to leave it unplugged overnight, or just always leave it plugged in, it's fine.
I think it might have to do with my using full-disk encryption, but I've been unwilling to go all the way through attempting a fresh install to fix.
So it’s like a desktop with a hinge. I recently moved to a MacBook after being a win/Linux user my whole life and the thing I love the most is the feeling that if I close the lid, all is going to be ok and I can immediately open it back up and it won’t freak out or I won’t find it’s still working on sleeping.
Being at an airport and closing it, putting it in the bag, boarding, resuming work. Or relocating at home from table to desk to couch, things you do with a laptop cost you battery and heat with a framework?
YMMV but both my macbooks occasionally display evidence that they were awake while they were asleep (e.g. if i close the hing at 10pm and open it at 8am, it might show 2:14am for a few seconds before catching up, but also they show new unread messages even before connecting to wifi). Weirdly my 2013 macbook is much much better at going to sleep and waking up with nearly the same battery capacity, whereas my 2019 (work laptop) will often run down 15-40% of its battery over the weekend while completely closed.
Ironically my company issued Macbook is also annoying about this, in the sense that it regularly makes noises or wakes up my monitor when it should be sound asleep.
But my Framework never actually goes all the way to sleep, even when it looks like it has, and I've given up trying to figure out why.
