It’s only been five days since iOS 5 was officially released, not even a full week yet, and is already installed on one out of every three iOS devices. Obviously, this graph only includes iOS 5 compatible devices (iPad 1, iPad, iPhone, iPhone 3GS, and iPod touch 4G). The results in the graph comes from a mobile analytics SDK from Localytics that is integrated in thousands of apps from the App Store and using a range of “tens of millions of devices” as the sample size, according to them.
The percentage of devices already running iOS 5:
- 36% of iPad 2s observed are already running iOS 5
- 35% of iPhone 4s
- 33% of original iPads
- 27% of iPhone 3GS
- 23% of iPod Touch 3rd-gen
- 17% of iPod Touch 4th-gen
