Just something I noticed while browsing through the changes in iOS 6 is that the brightness setting seems different than in 5.1. When I first booted up in 6, the screen was set to full dark, which is strange given my former setting was 50%. Setting it back to 50% it felt WAY too bright. I've got it at about 20% brightness and it seems to be similar to what 50% used to be. At 100% bright, it hurts my eyes. Wonder if it will have any effect on battery life?
