For example, if battery life is particularly important to a user, he'll lean toward Huawei Ascend Mate, instead of Sony's Xperia. The top three Android smartphones in the best battery life category all went to Chinese vendors. Vivo Xplay came in the second, and Oppo N1got in the third place.
Battery Life Ratings
Why yet another rating system?
The world is full of benchmarks, product reviews, and consumer reports. Does it really need the Mobile Experience Alliance to launch yet another rating system for mobile devices?
Dino Brusco, general manager of the Mobile Experience Alliance, told EE Times that the motive behind the Certimo ratings was to come up with a meaningful benchmarking system that can serve both users and the mobile industry.
Faced with so many choices in mobile devices, with similar features and almost identical shapes, consumers are confused about how to compare them, and more importantly, how to choose the right device, explained Brusco.
The same goes for the industry. While handset OEMs can benchmark their devices in terms of MIPS (millions of instructions per second), pixels per inch, and other numerical measures, they actually struggle to figure out how to compete, where to invest R&D and how to promote their differences. To develop credible strategies, OEMs need to know where their mobile device stands in terms of the real-world user experiences it's delivering.
Asked who actually does all the ratings, Brusco stressed, "None of this matters if this were all done by a handset vendor."
BDTI, a developer and practitioner of benchmarking processors over the last 20 years, is responsible for delivering independently certified test results for the Certimo ratings, said Jeff Bier, president of BDTI. "We would like to think that BDTI delivers rigor, integrity and objectivity to the process."
Bier acknowledged that BDTI is known for benchmarking on the processor level, with no experience in mobile devices. "Still, we were appalled by the lack of objectivity" in benchmarks used for mobile devices, he said.
About a year ago, BDTI took on the project, hired Brusco, a former vice president of mobile innovation center at Huawei device, and decided to put the initial regional focus on China.
