Don't get me wrong, overall, very happy with my XS Max. But Apple sold us a bill of goods on the improved battery. It barely lasts any longer than my X - with the smaller battery - did. In fact, I think the XS Max drains more on standby than my X ever did. Was hoping it would be as significant an improvement as going from a regular iPhone to a Plus was, but it's not at all. There. Just wanted to get that out of my system.
