iPhone cleans up in J.D. Power smartphone survey

J.D. Power's latest batch of smartphone rankings are out, and it's another strong showing for Apple as well as good news for users all round, as more claim to be content with their advanced devices than every before. Apple maintains its top spot, with the iPhone scoring 838 out of a possible 1,000 when rated by users for performance, physical design, ease of operation and features. Bringing up second place is HTC, the only other manufacturer to make it above the 800 mark (and only just at that, with a score of 801).

Samsung (777), Motorola (775) and RIM (762) take third, fourth and fifth place, leaving LG and Palm to languish behind with 760 and 733 respectively. Nokia brings up the last place, with its underwhelming Symbian smartphones leading to a score of 721.

Meanwhile, in J.D. Power's star ratings, only Apple managed to score the full five out of five in any category – in fact, it managed a clean sweep – though HTC was rated well for physical design and feature set. According to the research, users are happiest when their smartphone is under 5oz in weight and less than 0.45-inches wide, and people prefer all-touch phones to either QWERTY-only or QWERTY/touch hybrids.
