Apple has released iOS 7 beta 5 yesterday, less than a week after beta 4. I guess developer site hacking incident did disrupt the release cycle. After a day of use, I can see that battery life remains good. But it seems less stable (as betas go) and I’m getting more crashes. There are more UI tweaks especially on the Settings app: icons are more colorful (but still flat). Less like Android Jelly Bean :P
