A BatteryXPRT bug fix is on the way

Some time ago, we started to see unusual BatteryXPRT battery life estimates and high variance on some devices when running tests at the default length of 5.25 hours (seven 45-minute iterations). We suspected that the problem resulted from changes in how new OS versions report battery life on certain devices (e.g., charging past a reported level of 100 percent). In addition, the progress of battery technology in general means that the average phone battery lasts much longer than it did a few years ago. Together, these factors sometimes led to BatteryXPRT runs where the OS reported little to no battery decrease during the first few iterations of a test. We concluded that 5.25 hours wasn’t long enough to produce an accurate battery life estimate.

After extensive experimentation and testing, we’ve decided to release a new build that increases the default BatteryXPRT test length from 5.25 hours (seven iterations) to 45 hours (60 iterations) to allow enough time for a full rundown on most phones. Based on our testing, we consider full rundown tests to be the most accurate and will use those exclusively in our Spotlight testing and elsewhere. Testers will still have the option of choosing shorter test durations, but BatteryXPRT will flag the results with a qualifier that recommends performing a full rundown.

We plan to release the updated build by the end of next week and update BatteryXPRT documentation to reflect the changes. We have not changed any of the workloads and both performance results and full-rundown battery life estimates will be comparable to results from earlier builds.

BatteryXPRT continues to be a useful tool for gauging the performance and expected battery life of Android devices while simulating real-world tasks. If you have any questions about BatteryXPRT, please feel free to ask!

The 2018 XPRT Spotlight Back-to-School Roundup

With the new school year approaching, we’re pleased to announce that we’ve just published our third annual XPRT Spotlight Back-to-School Roundup! The Roundup allows shoppers to view side-by-side comparisons of XPRT test scores and hardware specs from some of this school year’s most popular Chromebooks, laptops, tablets, and convertibles. We tested the devices in our lab using the XPRT benchmarks and provide not only performance scores, but also photo galleries, PT-verified device specs, and prices. Parents, teachers, students, and administrators who are considering purchases for use in their education environments have many options, and the Roundup can help make their decisions easier by gathering product and performance facts in one convenient place. We’ll continue to add devices to the Roundup, including the new Microsoft Surface Go, as they arrive over the next few weeks.

The Back-to-School Roundup is just one of the features we offer through the XPRT Weekly Tech Spotlight. Every week, the Spotlight highlights a new device, making it easier for consumers to select a new laptop, phone, tablet, or PC. Recent devices in the Spotlight include the Acer Chromebook Tab 10, the 2018 Samsung Chromebook Plus, the Intel Hades Canyon NUC mini PC, and the OnePlus 6 phone. The Spotlight device comparison page lets you view side-by-side comparisons of all of the devices we’ve tested.

If you’re interested in having your devices featured in the XPRT Weekly Tech Spotlight or in this year’s Black Friday and Holiday Showcases, which we publish in late November, visit the website for more details.

If you have any ideas for the Spotlight page or suggestions for devices you’d like to see, let us know!
