Durham, NC, April 20— Principled Technologies and the BenchmarkXPRT Development Community have released CrXPRT 2, a free app that measures Chromebook battery life, as well as how fast a Chromebook handles everyday tasks like playing video games, watching movies, editing pictures, and doing homework. Testers can install the app on Chromebooks from the Chrome Web Store or by clicking the Chrome Web Store button on CrXPRT.com.

The CrXPRT 2 performance test, which measures a Chromebook’s speed, gives testers an overall score and individual scores for each workload. In addition to an estimated battery life expressed in hours and minutes, the battery life test produces a separate performance score and a frames per second (FPS) rate for a built-in HTML5 gaming component. CrXPRT is user-friendly, delivering results that consumers can understand.

“CrXPRT is a popular, easy-to-use benchmark run by manufacturers, tech journalists, and consumers all around the world,” said Bill Catchings, co-founder of Principled Technologies, which administers the BenchmarkXPRT Development Community. “CrXPRT 2 continues CrXPRT’s legacy of providing relevant and reliable performance and battery life data for Chrome OS devices.”

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

CrXPRT 2 is here!

on April 16, 2020

We’re excited to announce that CrXPRT 2 is now available to the public! Testers can install the app on Chromebooks by using this link to the Chrome Web Store listing, or by clicking the Chrome Web Store button on CrXPRT.com.

For those who may have missed our previous discussions about what’s new with CrXPRT 2, here is a recap of the key differences between CrXPRT 2015 and CrXPRT 2:

  • CrXPRT 2 has an all-new UI, with a focus on intuitive navigation.
  • The CrXPRT 2 performance test includes six of the seven workloads in CrXPRT 2015. Newer versions of Chrome can’t run the Photo Collage workload without a workaround, so we removed it from CrXPRT 2.
  • We updated the image resolutions and sizes for the Photo Effects and Face Detection workloads.
  • The battery life test now requires a full rundown, so the length of battery life tests will vary according to the battery life of the systems under test.
  • CrXPRT 2 no longer requires testers to enter luminance and audio measurements for battery life tests.
  • We added a second video playback segment to each battery life iteration.


As we’ve noted before, CrXPRT 2 overall performance test scores and battery life measurements are not comparable to CrXPRT 2015 scores. For testers that need to access CrXPRT 2015 for legacy comparison testing, we will continue to make CrXPRT 2015 available via a link on CrXPRT.com.

We appreciate everyone’s input during the CrXPRT 2 development process. If you have any further questions about CrXPRT 2, please let us know!

Odds and ends

Today, we want to share quick updates on a few XPRT topics.

In case you missed yesterday’s announcement, the CrXPRT 2 Community Preview (CP) is now available. BenchmarkXPRT Development Community members can access the preview using a direct link we’ve posted on the CrXPRT tab in the XPRT Members’ Area (login required). This tab also provides a link to the CrXPRT 2 CP user manual. You can find a summary of what’s new with CrXPRT 2 in last week’s blog. During the preview period, we allow testers to publish CP test scores. Note that CrXPRT 2 overall performance test scores and battery life measurements are not comparable to those from CrXPRT 2015.

We’ll soon be publishing our first AIXPRT whitepaper, Introduction to AIXPRT. It will summarize the AIXPRT toolkits and workloads; how to adjust test parameters such as batch size, levels of precision, and concurrent instances; how to use alternate test configuration files; and how to understand test results. When the paper is available, we’ll post it on the XPRT white papers page and make an announcement here in the blog.

Finally, in response to decreased downloads and usage of BatteryXPRT, we have ended support for the benchmark. We’re always monitoring usage of the XPRTs so that we can better direct our resources to the current needs of users. We’ve removed BatteryXPRT from the Google Play Store, but it is still available for download on BatteryXPRT.com.

If you have any questions about CrXPRT 2, AIXPRT, or BatteryXPRT, please let us know!

The CrXPRT 2 Community Preview is almost here!

on March 12, 2020

We appreciate everyone’s patience and feedback during the CrXPRT 2 development process. We’re excited to say that we’re now wrapping up some final details and expect to release the Community Preview (CP) within the next week.

Here is a summary of the key differences between CrXPRT 2015 and CrXPRT 2:

  • As we mentioned a few weeks ago, CrXPRT 2 has a completely new UI in line with the functional and aesthetic themes we used for the latest versions of WebXPRT, MobileXPRT, and HDXPRT, with a focus on intuitive navigation.
  • The CrXPRT 2 performance test includes six of the seven workloads in CrXPRT 2015. Newer versions of Chrome can’t run the Photo Collage workload without a workaround, so we removed it from CrXPRT 2.
  • We updated the images in the Photo Effects and Face Detection workloads to reflect more contemporary file resolutions and sizes.
  • The CrXPRT 2 battery life test requires a full rundown, so you’ll need charge your device to 100 percent before you can start the test, and the length of battery life tests will vary according to the battery life of the systems under test.
  • We no longer require testers to enter luminance and audio measurements in order to run a battery life test.
  • We added a second video playback segment to each battery life iteration.


We allow testers to publish CP test scores, but CrXPRT 2 overall performance test scores and battery life measurements are not comparable to CrXPRT 2015 scores.

Only BenchmarkXPRT Development Community members will be able to download the CrXPRT 2 CP. Because the Chrome team stopped providing search and browse functions for hosted and packaged Chrome apps in the Chrome Web Store, members will need a direct link to access the app. Once the app is available, we’ll post that link, along with the CrXPRT 2 CP user manual, on the CrXPRT tab in the XPRT Members’ Area (login required). We’ll also send a message to the community and post a notice here in the blog.

If you have any questions about CrXPRT 2 or joining the community, please let us know!

A preview of the new CrXPRT 2 UI

By Justin Greene
on January 30, 2020

As we get closer to the CrXPRT 2 Community Preview (CP), we want to provide readers with a glimpse of the new CrXPRT 2 UI. In line with the functional and aesthetic themes we used for the latest versions of WebXPRT, MobileXPRT, and HDXPRT, we’re implementing a clean, bright look with a focus on intuitive navigation. The screenshots below show how we’ve used that approach to rework the home, battery life test, performance test, and battery life test results screens. (We’re still tweaking the UI, so the screens you see in the CP may differ slightly.)

On the home screen, we kept the performance test and battery life test buttons, but made it clearer that you can choose only one. We also added a link to the user manual to the bottom ribbon for quick access.

If you choose to run a battery life test and click Next, the screen below appears. The CrXPRT 2 battery life test requires a full rundown, so you’ll need charge your device to 100 percent before you can start the test. Once you’ve done that, enter a name for the test run, unplug the system, and click Start. (Note that you no longer need to enter values for screen brightness and audio levels.)

The CrXPRT 2 performance test includes updated versions of six of the seven workloads in CrXPRT 2015. (As we discussed in a previous blog post, newer versions of Chrome can’t run the Photo Collage workload without a workaround, so we removed it from CrXPRT 2.)  To run the performance test, enter a name for the test run, customize the workloads if you wish, and click Start.

For the results screens, we wanted to highlight the most important end-of-test information while still offering clear paths for options such as getting additional details on the test, submitting results, and running the test again. Below, we show the results screen from a battery life test. Note the “Main menu” link in the upper-left corner, which we added to all screens to give users a quick way to navigate back to the home screen.

CrXPRT 2 development and testing are still underway. We don’t yet have an exact release date for the CP, but once we do, we’ll announce it here in the blog.

What do you think about the new CrXPRT 2 UI? Let us know!
