Sleep time seems to be 10% battery drain every 24 hours.
From what I am understanding is that there's still quite a lot of quirks that need to be improved. Especially with game compatibility and third party launchers. Hopefully Valve will release Windows Drivers by the time the Steam Deck ships so we can compare it. But the suspend and sleep seems to work very well with the Steam Deck unlike how it works with Windows. The heptics have also improved since launch reviews via updates.
Also for cloud saves. If you are in the middle of the game, you need to save and close before picking up the game on your PC. Valve has introduced a new feature that will allow for more seamless pickup and play but that needs to be implemented by game devs.
Overall though, great hardware but software needs improvements. Sounds like Valve is listening though.
