Is the maximum transmit power greater, the higher the average peak current?

All conditions remain unchanged and only the Max WiFi TX power is changed. When the Max WiFi TX power is set to 0dm, the average peak current is 157ma. When the Max WiFi TX power is set to 10dBm, the average peak current is 140ma. When the Max WiFi TX power is set to 5dBm, the average peak current is 110dbm. From the experimental results, the average peak current is not linearly related to the maximum transmit power.
Could you please explain this phenomenon?

Are you sure the on air times and datarates are the same?

I am sure dataratesa is same.I don't understand what is "the on air times".The experimental environment is in the air.

The time the radio is transmitting. If lower txpower may be more retries or slower bitrates.

Based on what measurement
