So, curious to know; out of the people who are having iOS9 problems, how many have actually bothered to call apple or log a support issue for it? I'm guessing close to zero?
I've had problems with iOS upgrades before, they were resolved fairly quickly on advice from Apple via telephone.
I logged performance issues all through the beta and have send feedback post release.
The problem is that it is slower than iOS 8 and I don't think Apple gives a damn.
I can't notice milliseconds of difference in launching apps, but since iOS 9 overall seems faster, especially safari; getting stuff done end to end seems faster. And even if that is not the case by the stop watch, the safari improvements, especially in older devices like my iPad 2, are tangible.
Its bleeding obvious when instead of a instant animation after tapping an app to open becomes a lag where the app icon turns black and waits before rendering an animation.
Differences in seconds do add up they make every single thing slower.
I'd be willing to say that iOS 9 is definitely slower on A5 devices, and if anyone can do side by side testing (clean install of iOS 8 & 9 + restored from the same backup) and show that iOS 9 is at least as fast as iOS 8 if not better - I'D LOVE to see it.
Notice how they never gave any statistics or figures about better performance, compare it to how they lay out exactly what to expect for the performance enchantments in El Capitan
here. If someone makes a claim like that without actual data to back it up expect that marketing is behind the claim and not anyone of the development side.
If they couldn't deliver, then why mention it at all. The iOS 9 site clearly says foundation will deliver improved performance etc. False advertising I say.
Besides - why should iOS 9 be slower? They've had a whole year to develop it and it has minimal new features compared to previous releases so I have no idea what they spent the last year doing.
all those people complaining, while this is one of the better IOS releases i've seen
maybe all you whining people should look for answers instead of bitching
maybe you all have old apps installed on your phone that is causing these lags ( I had that problem when ios 8 came out )
well that being said, I am having zero problems with Ios 9.1 Beta 2
THERE ARE NO ANSWERS!
If an operating system is running slower than the previous version on perfectly functional hardware across multiple devices on a CLEAN INSTALL, then what answers are there?
Its got nothing to do with me - its Apple's issue. Plenty of people reported lag and slow performance in the PBs and yet they are apparently still evident in the public release.
