Got the 5090 version, max battery saver and battery everything on with optimus on, dim af, streaming youtube and no other apps, 4-5h maybe. Seems like the battery is 85 mwh instead of 90. Batterypro states about 13mW discharge rate after a while of jumping to high 30s. Rivatuner reports about 20 mW usage idle with no applications using it.
How is it that asus manages, what? 8-10h on the same cpu and 4090.
