I've got a Framework I am not too upset with, but the battery life (especially during sleep) is definitely one of my gripes. I still have yet to try powertop or other tools to optimize, maybe I would be proven wrong.

Sleep just ceased to exist in the last few years and got replaced with an always on, low power mode.

I believe the reasoning was partly that suspend to RAM had serious reliability issues due to the complexity of saving the state, partly that people starting expecting cell phone-like performance where eg, mail is always received.
