Why is this? Is it because of increased power requirements of 3g, 4g etc? Or all the extra useless processing devices do? (Ignoring the screen...)

My first phone was a siemens c30. Apparently the battery capacity was ~600mAh and gave >10 days standby where the Apple watch has ~200mAh and gives ~18h. So the c30 lasted over 3 times longer on the same charge?

Is it really unfeasible to expect us getting back to that same efficiency by cutting back in some areas?
