At least as important to me, is what is battery life like? With a 61 Wh battery on what is essentially a mobile processor, can I get 20+ hours of use out of it?

A VisionFive 2 with the same chip uses 3.4 W idle, just with automatic down clocking (I think 375 MHz is the lowest). So that would be potentially 18 hours from a 61 Wh battery. But a laptop also has to drive a screen backlight. On the other hand, maybe the JH7110 has has some lower power sleep mode that was not being used by the software on the VisionFive 2.
