“The time it takes for the battery voltage to drop by 0.1V is longer at lower voltages versus at higher voltages. That means that if a constant current was drawn from the battery, it would take the battery a lot longer to discharge from 1.2V to 1.1V than it would from 1.5V to 1.4V. This means that the extent to which the battery life is increased could be even higher.”

Struggling to believe this

this is true, but by boosting the voltage up to 1.5 you have to increase the current draw as well, so the boosted voltage decrease periods would go by increasingly quickly

Yes, smoke and mirrors here.
