I upgraded to an 18 pro from the 15 pro, partially on a whim since there were good trade in deals and partly because of the battery life promises. The battery is better, but I probably would have been fine just getting my old battery replaced. Other than that, I don't see really any other benefit. I preferred the smaller and lighter 15 pro model and it kind of pisses me off that they keep sneaking in an extra 0.1" and 10 grams every other year.
