well the cpu along with gpu and display are most power hungry so even if u say the display uses same power has cpu/gpu that 15 hours and u can put that down to 12 hourse for other things

You are predicting battery life for a device with no display, storage, haptic feedback or illumination.

Usually the CPU is not the only energy cost.
