The initial simulations are based on the current values specified in the datasheet of the specific vendor.
Then, based on the actual measurements, the current values are reapplied to a second simulation.
The results are shown in Figure~\ref{fig:power_plot}.

As it can be seen, the $I_{DD}$ currents in the datasheet are overly pessimistic for all vendors:
The simulations based on the datasheets show on average a $4.8\times$ higher power consumption than the actual power measurements.
However, when the measured currents are applied to the simulation, there is still a small discrepancy:
