BatteryXPRT: A quick and reliable way to estimate Android battery life

on May 25, 2017

In the last few weeks, we reintroduced readers to the capabilities and benefits of TouchXPRT and CrXPRT. This week, we’d like to reintroduce BatteryXPRT 2014 for Android, an app that evaluates the battery life and performance of Android devices.

When purchasing a phone or tablet, it’s good to know how long the battery will last on a typical day and how often you’ll need to charge it. Before BatteryXPRT, you had to rely on a manufacturer’s estimate or full rundown tests that perform tasks that don’t resemble the types of things we do with our phones and tablets every day.

We developed BatteryXPRT to estimate battery life reliably in just over five hours, so testers can complete a full evaluation in one work day or while sleeping. You can configure it to run while the device is connected to a network or in Airplane mode. The test also produces a performance score by running workloads that represent common everyday tasks.

BatteryXPRT is easy to install and run, and is a great resource for anyone who wants to evaluate how well an Android device will meet their needs. If you’d like to see test results from a variety of Android devices, go to BatteryXPRT.com and click View Results, where you’ll find scores from many different Android devices.

If you’d like to run BatteryXPRT:

Simply download BatteryXPRT from the Google Play store or BatteryXPRT.com. The BatteryXPRT installation instructions and user manual provide step-by-step instructions for how to configure your device and kick off a test. We designed BatteryXPRT 2014 for Android to be compatible with a wide variety of Android devices, but because there are so many devices on the market, it is inevitable that users occasionally run into problems. In the Tips, tricks, and known issues document, we provide troubleshooting suggestions for issues we encountered during development testing.

If you’d like to learn more:

We offer a full online BatteryXPRT training course that covers almost every aspect of the benchmark. You can view the sections in order or jump to the parts that interest you. We guarantee that you’ll learn something new!

If you’d like to dig into the details:

Check out the Exploring BatteryXPRT 2014 for Android white paper. In it, we discuss the app’s development and structure. We also describe the component tests; explain the differences between the test’s Airplane, Wi-Fi, and Cellular modes; and detail the statistical processes we use to calculate expected battery life.

If you’d like to dig even deeper, the BatteryXPRT source code is available to members of the BenchmarkXPRT Development Community, so consider joining today. Membership is free for members of any company or organization with an interest in benchmarks, and there are no obligations after joining.

If you haven’t used BatteryXPRT before, try it out and let us know what you think!

Another pronunciation lesson

By Eric Hale

on May 18, 2017

Knowing how to say the terms we read on-line can be a bit of a mystery. For example, it’s been 30 years since CompuServe created the GIF format, and people are still arguing about how to say it.

A couple of months ago, we talked about how to pronounce WebXPRT. In the video we pointed to, the narrator openly says he’s confused about how to say “XPRT.” For the record, it’s pronounced “expert.”

Recently, we came across another video, which referred to CrXPRT. The narrator pronounced it “Chrome expert.” The “expert” part is correct, but the “Chrome” part is not. It’s an understandable mistake, because Cr is the chemical symbol for chromium. That’s why we chose it! However, we pronounce the C and R individually. So, the name is said “C R expert.”

All that being said, it was great to see CrXPRT in the classroom! When we created CrXPRT, the education market was a big consideration, as you can tell from this CrXPRT video. We love seeing the XPRTs in the real world!

CrXPRT: a valuable tool for evaluating Chromebooks

By Justin Greene

on May 11, 2017

Last week, we reintroduced readers to TouchXPRT 2016. This week, we invite you to get to know CrXPRT, an app for Chrome OS devices.

When you buy a Chromebook, it’s important to know how long the battery will last on a typical day and how well it can handle everyday tasks. We developed CrXPRT 2015 to help answer those questions. CrXPRT measures how fast a Chromebook handles everyday tasks such as playing video games, watching movies, editing pictures, and doing homework, and it also measures battery life. The performance test, which measures the speed of your Chromebook, gives you individual workload scores and an overall score. 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.

CrXPRT completes the battery life evaluation in half a workday, and delivers results you can understand. Before CrXPRT, you had to rely on the manufacturer’s performance claims and estimated battery life. Now, CrXPRT provides an objective evaluation tool that’s easy to use for anyone interested in Chromebooks. To learn more about CrXPRT, check out the links below.

Watch CrXPRT in action:

To test your Chromebook’s performance or battery life:

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.

If you’d like to dig into the details:

Read the Exploring CrXPRT 2015 white paper. In it, we discuss the concepts behind CrXPRT 2015, its development process, and the application’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.

If you have a Chromebook you’d like to evaluate, give CrXPRT a try and let us know what you think!

Getting to know TouchXPRT

By Justin Greene

on May 4, 2017

Many of our community members first encountered the XPRTs when reading about WebXPRT or MobileXPRT in a device review, using TouchXPRT or HDXPRT in an OEM lab, or using BatteryXPRT or CrXPRT to evaluate devices for bulk purchasing on behalf of a corporation or government agency. They know that specific XPRT provided great value in that context, but may not know about the other members of the XPRT family.

To help keep folks up to date on the full extent of XPRT capabilities, we like to occasionally “reintroduce” each of the XPRTs. This week, we invite you to get to know TouchXPRT.

We developed TouchXPRT 2016 as a Universal Windows Platform app for Windows 10. We wanted to offer a free tool that would provide consumers with objective information about how well a Windows 10 or Windows 10 Mobile laptop, tablet, or phone handles common media tasks. To do this, TouchXPRT runs five tests that simulate the kinds of photo, video, and music editing tasks people do every day. It measures how quickly the device completes each of those tasks and provides an overall score. To compare device scores, go to TouchXPRT.com and click View Results, where you’ll find scores from many different Windows 10 and Windows 10 Mobile devices.

TouchXPRT is easy to install and run, and is a great resource for anyone who wants to evaluate the performance of a Windows 10 device.

If you’d like to run TouchXPRT:

Simply download TouchXPRT from the Microsoft Store. (If that doesn’t work for you, you can also download it directly from TouchXPRT.com.) Installing it should take about 15 minutes, and the TouchXPRT 2016 release notes provide step-by-step instructions.

If you’d like to dig into the details:

Check out the Exploring TouchXPRT 2016 white paper. In it, we discuss the TouchXPRT development process, its component tests and workloads, and how it calculates individual workload and overall scores. We also provide instructions for automated testing.

BenchmarkXPRT Development Community members also have access to the TouchXPRT source code, so consider joining today. There’s no obligation and membership is free for members of any company or organization with an interest in benchmarks.

If you haven’t tried running TouchXPRT before, give it a shot and let us know what you think!
