Following up on CrXPRT 2 battery life errors

A few weeks ago, we discussed error messages that a tester received when starting up CrXPRT 2 after a battery life test. CrXPRT 2 battery life tests require a full battery rundown, after which the tester plugs in the Chromebook, turns it on, opens the CrXPRT 2 app, and sees the test results. In the reported cases, the tester opened the app after a battery life test that seemed successful, but saw “N/A” or “test error” messages instead of the results they expected.

During discussions about the end-of-test system environment, we realized that some testers might be unclear about how to tell that the battery has fully run down. During the system idle portion of CrXPRT 2 battery life test iterations, the Chromebook screen turns black and a small cursor appears somewhere on the screen to let testers know the test is still in progress. We believe that some testers, seeing the black screen but not the cursor, believe the system has shut down. Restarting CrXPRT 2 before the battery life test is complete could explain some of the “N/A” or “test error” messages users have reported.

If you see a black screen without a cursor, you can check to see whether the test is complete by looking for the small system power indicator light on the side or top of most Chromebooks. These are usually red, orange, or green, but if a light of any color is lit, the test is still underway. When the light goes out, the test has ended. You can plug the system in and power it on to see results.

Note that some Chromebooks provide low-battery warnings onscreen. During CrXPRT 2 battery life runs, testers should ignore these.

We hope this clears up any confusion about how to know when a CrXPRT 2 battery life test has ended. If you’ve received repeated “N/A” or “test error” messages during your CrXPRT 2 testing and the information above does not help, please let us know!

Principled Technologies and the BenchmarkXPRT Development Community release the CrXPRT 2 benchmark for Chromebooks

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.

The CrXPRT 2 Community Preview is almost here!

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!

CrXPRT is more valuable than ever

Digital Trends recently published an article discussing various rumors about the future of the Google Pixelbook line. Pixelbooks were some of the first Chromebooks with high-end hardware specs, and they were priced accordingly. Whether or not the rumors discussed in the article turn out to be true, the author points out that the Pixelbook prompted several other vendors, such as HP and Lenovo, to take a chance on high-end Chromebooks. It seems like high-end Chromebooks are here to stay, but given the unique constraints of the Chrome OS environment, buyers are often unsure if it’s worth it to shell out the extra money for a premium model.

We developed CrXPRT to help buyers answer these questions. CrXPRT is a benchmark tool that measures the battery life of your Chromebook as well as how fast it handles everyday tasks like playing video games, watching movies, editing pictures, and doing homework. The performance test gives you individual workload scores and an overall score based on the speed of the device. The battery life test produces an estimated battery life time, a separate performance score, and a frames-per-second (FPS) rate for a built-in HTML5 gaming component.

You don’t have to be a tech journalist or even a techie to use CrXPRT. To learn more, check out the links below.

Testing the performance or battery life of your Chromebook

Simply download CrXPRT from the Chrome Web Store. Installation is quick and easy, and the CrXPRT 2015 user manual provides step-by-step instructions. A typical performance test takes about 15 minutes, and a battery life test will take 3.5 hours once the system is charged and configured for testing. If you’d like to see how your score compares to other Chromebooks, visit the CrXPRT results page.

Want to know more?

Read the Exploring CrXPRT 2015 white paper, where we discuss the concepts behind CrXPRT, its development process, and the app’s structure. We also describe the component tests and explain the statistical processes used to calculate expected battery life.

BenchmarkXPRT Development Community members also have access to the CrXPRT source code, so if you’re interested, join today! There’s no obligation and membership is free for members of any company or organization with an interest in benchmarks.

Give CrXPRT a try and let us know what you think!
