    Claims and test results

    The claims on these pages are mainly based on results from tests conducted by Strategy Analytics, an independent global company specializing in market analysis. In some cases, tests were also conducted in laboratories at Sony Mobile Communications Inc. All claims were verified at the time of testing. However, as the mobile landscape changes quickly and new phone models are released on a continuous basis, we cannot guarantee that all claims are still valid as you read this. Please see the date specified at the bottom of each claim and test specification for reference. For more information on Strategy Analytics, please visit the Strategy Analytics homepage.

    Definition of competitive set

    The competitive set included in this report for technical testing was determined by Strategy Analytics to be the latest flagship devices released by global smartphone vendors prior to the dates of testing (May 19-20th 2016). These include: Apple iPhone 6S, HTC 10, Huawei P9, LG G5, and Samsung Galaxy S7.

    Methodology: camera speed

    Strategy Analytics’ researchers calculated the amount of time it took for each smartphone to quickly launch from standby and capture a picture.

    Strategy Analytics’ researchers identified the quickest shortcut to launch the camera application from standby mode on every smartphone in both competitive sets.

    The smartphone being tested was securely fastened on a tripod that was placed 70cm from a visually distinct object in a well-lit area that exceeded 2000 lux.

    A series of 10 quick launches were performed on each smartphone, which was being recorded on a 240 Frames Per Second (FPS) camera that was trained on the smartphone being tested.

    The videos resulting in the highest and lowest times were eliminated from the test. From the remaining 8 videos, time measurements were taken from the point when the camera shortcut was first activated, to the first frame when an audial shutter click could be heard in playback software.

    Methodology: autofocus

    Strategy Analytics’ researchers undertook a series of “head-to-head” competitive assessments, each with two competitor devices stationed on a secure camera rig.

    The cameras from each device were set to focus on a stationary individual. This individual then proceeded to run towards the camera rig. A picture was then captured on both devices at the same time, once the running individual had crossed a determined point in the scene.

    Strategy Analytics assessed the image captured on each device to objectively determine, based upon position of the object and sharpness of the image, which device captured the moving target sooner while in focus.

    All devices were compared ‘head-to-head’ with each other. Where one device produced images that were sharper and with the subject more centralized than the others, it was deemed to deliver the most precise autofocus technology.

    World’s Most Stable Video Capture

    Consumer Test

    All devices were firmly attached to a metallic apparatus onto a bicycle so that the footage could be captured simultaneously on all devices. This ensured that any motion or shaking was experienced identically by each device during the capture process.

    Over a period of two days, 201 consumers assessed the quality of the video footage produced by each of the smartphones. Consumers evaluated the video footage created side-by-side on a large screen (40”) HD monitor. To eliminate bias, the video clips were only identified by letter. The order of exposure was counterbalanced. Participants rated the image for overall video stability on a scale of 1 to 5, where 1 was “very poor” and 5 was “very good.”

    2. 2Strategy Analytics’ SpecTRAX database is an extensive proprietary resource consisting of two key datasets: specifications and availability data. The specifications contained in SpecTRAX cover over 300 attributes relating to over 23,000 announced smartphone, mobile-phone, tablet, mobile-hotspot, and USB dongle SKUs. Over 150 new device models are added manually to the database each month, as and when they are announced by the OEMs. Devices are marked as available if they appear in the portfolio of any of the 300 network operators/retailers whose websites we track in 48 countries on a daily basis. Strategy Analytics’ PriceTRAX database tracks mobile device retail pricing across 48 countries and contains over 50 million unique smartphone, mobile phone, tablet, and smartwatch prices dating back to 2010. Retail pricing (unsubsidized, prepaid [PAYG], and post-paid [contract]) is scraped weekly and linked directly to devices within the SpecTRAX database.
