The battery life is quite horrendous. Bizarre not to offer usb c charging
Just web browsing lasted 85 minutes
The same model with an i9 13950hx and 4090 did 260 minutes.

Eh its the CPU. It's well known by now the 7945HX is a desktop class chip. It doesn't have any mobile specific optimizations.
Am quite confident something like 7940HS combined with the same 7900M will have much better battery life.
Other RDNA3 based laptops that has 7040HS class CPU paired with them have class leading battery life.
Other rdna3 laptops top out at the small monolithic navi 33 die though.
