While it has been less than a week since its release, it has been reported that iOS 8’s adoption rate is currently at around 30%. This is compared to iOS 7 which managed to nab a whopping 52% market share within its first week. However we suppose this is to be expected as iOS 7 was a much more drastic change compared to iOS 8.
It could also be possible that many don’t see the new features as worth breaking their jailbreak for, or it could also be that due to hardware incompatibility or a less-than-optimal experience like those with the iPhone 4S could be causing some iOS users to hold off from updating to iOS 8 for now.
There have also been reports of higher app crash rates, WiFi, and battery life issues could also be discouraging users from updating. In any case we have to wonder if iOS 8 will eventually hit the same adoption as iOS 7 at a later date, but for now it does seem to be a tad slow.
