This is highly dependent on your machine and configuration.

I just got a framework 13 AMD with the 7840U chip. Seems to idle around -4-5W of total system power. Minimal loads with browsing etc will be around 7-8 watts. Windows still seems to be better optimized but it’s not bad at all considering.

How would you compare the battery to the Galaxy Fold 4? Also heard reports of it overheating, have you experienced that?
