PNaCl Further details about each workload can be found in Table 1 The performance suite runs for seven iterations and reports an overall score and individual workload scores The performance test takes approximately 20 minutes to complete About the battery life test The battery life test includes all seven workloads from the performance suite plus video playback audio playback and HTML5 gaming scenarios It also incorporates realistic periods of wait time for a total of 11 components Table 1 describes the battery life workloads in more detail Page 2 of 14 BenchmarkXPRT Development Community Each iteration of the battery life test lasts for 30 minutes and is comprised of approximately 18 minutes of active workloads and 12 minutes of wait idle time However since different devices work at different speeds the exact amount of idle time will vary by device By default the test runs a total of seven iterations so the battery life test will take 3 hours and 30 minutes to complete You may also set the test to run for 4 5 hours 5 5 hours or until the battery is exhausted These extended tests require more iterations of the workload than the standard seven iteration test but are the same as the standard test in all other respects The battery life test produces detailed results information including an estimated battery life with a 95 percent confidence interval a performance score based on the seven performance suite workloads and a fr
