It's not surprising that Apple's iPhone won highest customer satisfaction and loyalty ratings given that customers line up at the brand's stores for product releases. The iPhone recently took top honors in the 2012 J.D. Power and Associates Customer Satisfaction Survey of U.S. smartphone users. Overall, consumers gave the brand a score of 839 out 1,000.
Apple's iPhone scored well for its features, physical design, ease of operation and performance.
Most customers rated phones poorly because of dissatisfaction with battery life. As a result, owners of 3G phones reported higher satisfaction than those with 4G models. More strain is being put on battery performance as the devices become increasingly complex and owners use them more. In particular, 4G models were cited as the most problematic.
One surprising finding - design may not be as important as developers previously thought. Only 20 percent of those surveyed said design played a significant role in their satisfaction with the product. Additionally, consumers reported that when they are satisfied with a particular brand's phone, they are likely to buy from that company again when they need an upgrade.
