It sounds like it would _not_ have longer battery life, in the sense of "how many days can I go in between having to charge"
It sounds like the battery can withstand more charge cycles before getting crappy and needing replacement (eg, your phone might take 4 years instead of 2 before you have to replace the battery) -- way less useful
