It has to do with the active radios and frequencies used + reception. All cell phone radios adaptively change their transmit power based on the available reception. Certain frequencies are more susceptible to interference than others or the tower may be further away on on carrier than another at the place you are testing leading to differences in transmit power and the amount of battery life you have.
Verizon for example runs on AWS, higher frequency, higher signal attenuation... meaning more power needed for the cell phone to transmit back to the cell tower.
