ChadwickWill has a great post about the smaller iOS 6 features that you probably don't know about. These are the little refinements that Apple doesn't really mention much, but that add up to an overall much improved experience.
Some of the best ones that I found:
- The auto-dim feature got significantly improved in iOS 6. The best improvement is brightness adjustment in the lock screen. Before, in a dark room, I would be blasted with the iPad or iPhone’s default brightness before sliding to unlock and having it dim down to match the room’s brightness. Now, from the moment the screen turns on, the brightness is appropriate.
- The keyboard shortcuts in the “Keyboard” section of the “General” settings panel is now kept in sync with iCloud. I am so happy Apple did this.
- When Apple killed the system YouTube app, I was worried that I would be bound to YouTube’s terrible mobile site. Luckily, if you have Google’s official YouTube app, YouTube links from Safari and other apps will automatically open in it.
- Any media that is acquired through iTunes now has its play position synced through iCloud. Start watching a movie on one device, pick it up later on another without having to sync with iTunes.
- In all previous versions of iOS, the light sensor would sense the room’s brightness and then suddenly make the brightness adjustment. In iOS 6, the auto-brightness adjustment is gradual and much more subtle, like the Mac.
