Sanyo came out as the highest rated mobile phone in the annual J.D. Power and Associates 2004 U.S. Wireless Mobile Phone Evaluation Study. Sanyo phones ship in the US from Sprint PCS, with the MM-7400 being its latest offering. Five factors went into the survey:

• Features
• Durability
• Physical design
• Battery function
• Operation

The full ranking is as follows:

1. Sanyo
2. Samsung, LG
3. Motorola, Audiovox, Kyocera
4. Sony Ericsson, Nokia

Oddly enough market leader Nokia is on the bottom of the rankings.
