Durham, NC, February 25 — Principled Technologies and the BenchmarkXPRT Development Community have released HDXPRT 4, a free benchmark that gives objective information about how well Windows 10 devices handle common media-creation tasks. HDXPRT 4 uses real commercial applications, like Photoshop and MediaEspresso, to perform tasks based on three everyday scenarios: photo editing, video conversion, and music editing. After the test is finished, the tool provides an overall measure by generating a single performance score. Anyone can go to HDXPRT.com to compare existing performance results on a variety of devices, or to download the app for themselves.

“When we started working on HDXPRT 4, we knew we wanted to create a benchmark that accurately reflects the kind of work average consumers do when creating content on their PCs,” said Bill Catchings, co-founder of Principled Technologies, which administers the BenchmarkXPRT Development Community. “HDXPRT delivers clear results that make sense to the wide audience of buyers shopping for new Windows systems.”

HDXPRT is part of the BenchmarkXPRT suite of performance evaluation tools, which includes WebXPRT, MobileXPRT, TouchXPRT, CrXPRT, and BatteryXPRT. The XPRTs help users get the facts before they buy, use, or evaluate tech products such as computers, tablets, and phones.

A BatteryXPRT bug fix is on the way

Justin Greene
By Justin Greene
on October 18, 2018

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!

Updates on HDXPRT 4 and MobileXPRT 3

Justin Greene
By Justin Greene
on October 11, 2018

There’s a lot going on with the XPRTs, so we want to offer a quick update.

On the HDXPRT 4 front, we’re currently testing community preview candidate builds across a variety of laptops and desktops. Testing is going well, but as is often the case prior to a release, we’re still tweaking the code as necessary when we run into bugs. We’re excited about HDXPRT 4 and look forward to the community seeing how much faster and easier to use it is than previous versions. You can read more about what’s to come in HDXPRT 4 here.

On the MobileXPRT 3 front, proof-of-concept testing for the new and updated workloads went well, and we’re now working to implement the new UI. Below, you can see a mockup of the new MobileXPRT 3 start screen for phones. The aesthetic is completely different than MobileXPRT 2015, and is in line with the clean, bright look we used for WebXPRT 3 and HDXPRT 4. We’ve made it easy to select and deselect individual workloads by tapping the workload name (deselected workloads are grayed out), and we’ve consolidated common menu items into an Android-style taskbar at the bottom of the screen. Please note that this is an early view and some aspects of the screen will change. For instance, we’re certain that the final receipt-scanning workload won’t be called “Optical character recognition.”

We’ll share more information about HDXPRT 4 and MobileXPRT 3 in the coming weeks. If you have any questions about HDXPRT or MobileXPRT, or would like to share your ideas, please get in touch!
