Apple has topped the J.D. Power Wireless Smartphone Study for the tenth straight time, beating out competitors including Samsung, Nokia, and HTC.
For the first time, the survey breaks out smartphone rankings by carrier. Verizon iPhone customers were the happiest with their experiences, scoring 861/1000, while AT&T iPhone owners ranked 856/1000. The iPhone led on all carriers except for Sprint, where it came in second place to Samsung. Apple did come in well above average across all carriers.
Apple also led the twice-yearly rankings in 2009, 2010, 2011, 2012, and earlier in 2013.
