Compared to iOS 8 – which took about eight days to reach the 50 percent mark – iOS 9’s adoption rate is certainly much quicker. It only hit users last Wednesday, and managed to hit that mark by Saturday, September 19. But when you’ve already got articles on the Internet focused on how to fix iOS 9’s slow performance and lag issues, then adoption doesn’t necessarily popularity. A quick search on Twitter for “iOS 9” results in many top tweets with users complaining that iOS 9 is significantly slower than their previous software build – with people reporting app crashes, interface lags, and overall slower processing. While many are reporting from older devices, others (including yours truly) are experiencing lags on newer Apple devices.

To be fair to Apple though, other users that have updated to iOS 9 are actually reporting longer battery lives and lauding some of the OS’s new features. — J-Cruz⚾️ (@jcruzz28) September 21, 2015
