There were 52% iPhone updates to iOS 8
On its developer support page, Apple published a statistical result based on the number of iPhones accessing the App Store. Accordingly, Apple said that there are currently 52% of iPhones accessing the App Store recently updated to iOS 8.
The last statistics are on October 27, based on the data collection from iPhone access to the App Store, Apple said iOS 7 currently accounts for 43%, iOS 8 is currently higher at 52% and the remaining 5% are in older iOS versions.
This is not really an impressive growth figure, at the ceremony of announcing the new iPad, the figure of iOS 8 that Apple announced only stopped at 48%.
iOS 8 is expected to grow more slowly than iOS 7, which may come from the excessive amount of memory available to download and update (5GB) . If you own a 16GB iPhone, you will have to recalculate your storage to be able to go to iOS 8. Not to mention the reduced performance on older devices.
