The number of hours you spend and what you do on your phone today compared to 10 years ago is also not the same.

True, but the hardware also uses a lot less power then it used to.

That's not true in the slightest. Energy per instruction varies a lot but has not decreased that much on recent nodes. The resistance growth just outpaces the shrinking capacitance of the gates.

On top of that processors are faster, applications and sites are hugely more intensive to render, and the hardware (mainly antennas) suck up much more energy.

The ARM11 in the iphone 3 used <1 watt. The A13 in the iphone 11 uses 6 watts.
