I think the latest onboard Intel graphics (the ones used on gaming laptops at least) can drive a trio 4k screens [1] - I assume that would allow the battery last longer when not gaming. FWIW (anecdotal), I have a 4K non-touch Windows laptop with nVidia dGPU switching, and I can barely get 3h on battery (am a heavy Chrome user).
