Researchers Vince Tseng and Austin Sands at independent warranty provider SquareTrade analysed failure rates of over 50,000 smart phones covered by SquareTrade CarePlans, finding that Apple iPhones had the fewest malfunctions, with Motorola and HTC close behind.
The iPhone 4 was the most reliable phone, with 2.1 of units projected to have a non- accident malfunction in the first 12 months. However, phones by major makers of Android devices such as Motorola and HTC, were also found to be very reliable, with just 2.3 per cent and 3.7 per cent failure rates respectively.
BlackBerries and other smartphones were less reliable, with 6.3 per cent and 6.7 per cent failing in the first 12 months of use. However, SquareTrade says accidental damage is responsible for over 75 per cent of smartphone failures, and BlackBerry devices had the lowest one-year accident rate at 6.7 per cent while the iPhone 4 had the highest at 9.4 per cent.
The iPhone 3GS had the lowest overall failure rates, with just 11.7 per cent failing over the course of a year, and the aggregated pool of other smart phones had the highest failure rate at 16.9 per cent.
