Video performance analysis of seven popular smartphones

Leveraging test equipment from Spirent and Accuver, SRG conducted a benchmark study of seven smartphones in a commercial LTE network.  The test results reveal dramatic performance differences in the video player capabilities of the smartphones that we tested.

WE DISCUSS THE FOLLOWING:

• We analyzed video performance, including video freezes, video impairments, A/V synch and observed fps using a wide range of video resolutions and delivery protocols (HLS, RTSP, and HTTP).
• The Apple iPhone 6 Plus was the top-performing smartphone that we tested.  We also tested smartphones from HTC, LG and Samsung (4).
• We observed the the benefits of carrier aggregation (A&T has a soft launch of LTE-A in San Francisco), even when streaming relatively low bit rate video streams.
• Improvements in  chipsets (baseband + A/P) and device optimization have resulted in double-digit reductions in smartphone power consumption over the last few years).
