As the world’s iphone users start to upgrade to the new iOS 6 we wanted to find out how satisfied people were with their device, once they’d downloaded the new operating system. Our latest data shows that the iOS 6 leads to a decrease in device satisfaction among iPhone users in the US. This suggests that as consumers upgrade their operating system or buy the new iPhone, their initial reaction is not as positive as it has been in the past. Whilst the decrease is small, it does highlight that the new operating system is not an overwhelming success. It’s surprising, as the general trend is to see an increase in device satisfaction as consumers upgrade their mobile operating system from one version to another. For a comparison we also looked at Android users in the US, who reported an increase in device satisfaction in the latest upgrade to their operating system. In fact Android users are actually more satisfied with their device than iPhone users.
