Apple released iOS 6 last week, just ahead of their iPhone 5 and since then we have seen an absolutely mind-blowing 100 million iOS device owners update to iOS 6. According to mobile customer research firm On Device, iPhone satisfaction with users on iOS 6 is lower than it is with users on iOS 5.

A survey of 16,000 US iPhone owners was conducted by the firm, where they've said that customer satisfaction average dropped from 7.75 (iOS 5) to 7.65 (iOS 6). On Device CEO, Alistair Hill, says that the company has "always seen an increase in device satisfaction as consumer upgrade their mobile operating system from one version to another", and that it is unusual that iPhone satisfaction decreased with iOS 6.

The drop is tiny, so it's nothing to write home about - but it is something to consider. The iPhone, and its reception, has usually increased, as On Device have found - but with iOS 6 it has dropped. Could it be that people expected more? The whole Google Maps app debacle? Something else entirely?
