Right, but you did not get 22 hours of actual usage or screen on time. The usage stat is a strange thing.
Comparing the usage stat with percentage battery used is where people often fall short of understanding statistics. Sometimes, not always, the numbers need to be considered mutually exclusive. I can easily spend 3-6 hours playing music and it will be in the low single digits in percentage used. I can watch a single hour of Netflix and it will be easily in the double digits. Trying to then compare the numbers with usage time is useless. We would need a third statistic, which is app usage time, in order to make true sense of what these numbers really are.
IMO the updated stats aren;t much better than old ones. We can tell if a rogue app is blasting our batteries, but that's about it.
