A new study coming from Blancco Technology Group sheds some light on which devices are the most reliable, based on reliability. The study entitled State of Mobile Device Performance and Health reveals the device failure rates by operating systems, manufacturers, models and regions, as well as the most common types of performance issues. The report reveals that in Q2 2016, iOS devices had a 58% failure rate, marking the first time that Apple's devices have a lower performance rate compared to Android. It seems that the iPhone 6 had the highest failure rate of 29%, followed by iPhone 6s and iPhone 6S Plus. Android smartphones had an overall failure rate of 35%, an improvement from 44% in Q1 2016. Samsung, Lenovo and LeTV were among the manufacturers with the weakest performance and higher failure rates. Samsung scored 26% in failure rate, while Motorola just 11%. The study also reveals that iOS devices fail more frequently in North America and Asia compared to Android. Specifically, the failure rate in North America is 59%, while in Asia 52%. The failures could be influenced by the fact that the quality of smartphones shipped around the world varies.
