A Better Always-On Display

Apple also says that it’s been able to make the Series 6 more energy efficient than prior models, which in turn has allowed it to brighten up the Always-On Display (AOD) introduced on the Series 5 last year.

The AOD will apparently now be 2.5 times brighter than before, making it easier to read when your wrist is down, especially in direct sunlight. However, it’s likely that it will still go into a low refresh mode to save power when lowered, which means that you may still need to raise your wrist to see certain complications updated.
