Holy crap. Messages looks awesome with the dark mode. The message bubbles pop, and you can actually see the effect where messages near the top are a lighter color.
Preparing for OLED screens next year
This. I don't know if Apple will do total black to be honest though, that would save the most battery but look kinda ugly I think. Probably just a very dark gray. That still takes less energy than bright blue for example, right?
I totally forgotten that I use dark mode on my Mac Pro.
This looks cool. Still waiting for the option to turn off cellular on my iPad from control center or whatever name apple gave it.
Yeah Apple really should add customizable control center and dark mode then most of us would be very happy.. After that, add person by person read receipts, ability to lock particular apps/message threads/photo albums.. Multiple user support (add like a "family" or "guest" user for a particular finger print or passcode) would be awesome. Text selection on all iPhones would be sweet as well. I'd love to see a more in depth cellular usage and battery usage screen. With cellular usage I would love to see an option to have the settings reset every month on a customizable day, turn off cellular after a certain amount of data used, better tethering screen where you could hide your hotspot so you have to put in the SSID to find it, a list of devices that are connected and an ability to kick certain ones off or set data limits for particular devices, etc. Battery usage screen could use a specific "total screen on time" at the bottom. Also app-based battery usage stats for THAT battery cycle, not the last 24 hours which includes a portion of the previous cycle.. Better distinction between "standby" and "usage"...
Also a random little thing. I kinda wish Apple would let us hide the carrier name in the upper left

only the "domestic" carrier though, if you're roaming AT ALL you obviously want to know. Any reason why Apple can't do this? Android phones don't show carrier names but their status bars are a mess as it is.
Above all, I want a minor UI redesign. I think we definitely could see it. We tend to see changed roughly every 3 iOS versions. iPhone OS 3 refined a bit, iOS 4 brought big changes to springboard/animations, iOS 6 refined then iOS 7 redesigned, iOS 8 and 9 have both refined and it's feeling stale already. I just want more drop shadows, slightly muted colors, and a little less Gaussian blur, for the sake of performance.
