The company claims that Quantum is the industry’s first user experience analytics system to automatically execute consumer use cases on a mobile device while performing synchronized power consumption measurements.

The adoption of 4G applications such as VoLTE, video chat, streaming video, multi-player gaming and more demand that mobile devices be equipped with bigger screens, faster application processors and higher throughput modems.  As a result mobile device power consumption is increasing and has seen device makers respond by moving to higher capacity batteries which in many cases requires larger device sizes.

Space, heat and cost limitations means that the trend toward larger batteries is reaching its peak and designers in the mobile industry need to focus more on the power efficiency of mobile devices and chipsets.

“Our studies show that mobile devices with the best power efficiency outperform the worst by 50 to 70 percent depending on the use case, which is why we see a real opportunity for device makers and chipset providers to improve power efficiency and create a better overall mobile user experience,” said Des Owens, General Manager, Service Experience at Spirent Communications. “With Quantum, mobile operators, device makers and chipset providers can make true apples-to-apples comparisons of power consumption across devices and chipsets. Quantum’s use-case-based approach enables device and component makers to understand the real-world battery life of new products, identify component and design weaknesses and make improvements to power efficiency.”

Conducting large numbers of battery life test cases manually, especially complex tests, is usually cost and time prohibitive. As a result, manual test results seldom provide an accurate indicator of real-world battery life performance. Quantum allows thousands of tests to run automatically, ensuring power consumption and battery life measurements are statistically robust, repeatable and highly realistic with respect to real-world performance. Quantum is part of Spirent’s market-leading suite of user experience analytics solutions which include speech, call, web browsing, file transfer, video and battery life analytics.
