Looking at the battery capacities and hours of use seen in the tests, I was curious about the overall efficiency of the phones, so I could pick that apart from simply putting a honkin' large battery in to give more hours... so I divided the milliamp hours by the hours and got average milliamps across the test time for each phone during the test. Results below, but takeaways: iPhones Pro are more efficient than their non-pro equivalents. iPhones seem to be more efficient than their approximate Android equivalents. Google Pixels are the least efficient ones.
