  1. Still running iOS 8.4.1. I was going to update to 9.3 (I thought… if i don't do that NOW, I won't ever). My Internet took 24 hours for to do a backup of all my photos and WhatsApp chats on iCloud (now the saved data is out of date)… But after all, iOS 9.3 was blocked for the iPhone 5s. Sorry Apple, I gave you a chance, but wild bugs appeared. I had to restore iOS 8.4.1 again in Settings. Maybe 9.4 will be the great version, like iOS 8.4 was.

  2. Why are there different contents. It would make sense a real 1:1 comparison with same options. I saw a history on 9.3 etc. And why Facebook act different on both (ios influence?). And i think 8 its still faster. Is it possible to update from 8.3 to 8.4.1? Or is 8.3 also faster?

  3. Update My iPhone 5s to ios 9.3 and it feels more slow in some areas, third party application like Whatsapp for example and even safari when I scroll down. I come from ios 8.4.1. Has anyone experienced the same problem?

  4. I bought an iPod touch 6 and its with iOS 8.4.1 still and after seeing this I'm gonna keep iOS 8 forever I'm scared of updating and my device begin slow so I prefer to stay 8 , I don't miss any iOS 9 feature for normal use

  5. Seeing booting slower at #everythingapplepro and faster here and similarly opposite results on benchmarks it's quite clear that these OS versions are neck to neck and with all the new features it's worth the upgrade!! Good going apple. Can't be blamed for planned obsolence anymore!

  6. Upgraded to 9.3 from 8.4.1 at long last. Any lag in folder view/control center/notifications/spotlight is only on the first launch right after a reboot. Stays mostly very smooth on the 5s afterward. (Update for this below) There is a stupid 'jump up a few pixels' after clicking any option in the main settings window before the next page is launched.

    The major improvements to the music app and other features are well worth one minor cosmetic hiccup..

    UPDATE: Fix that setting jump by reducing text size by one notch under display and brightness.

  7. Seems that they fixed the CC lag and Youtube window slow swipe. I'd love to see if the lagging in Mobile networks app list is also fixed, or various 3rd party apps with listviews, but I sold the 5S because of those issues three months ago. Too late Apple.
