Today we’re releasing a new build of BatteryXPRT 2014 for Android (v101) at BatteryXPRT.com and the Google Play store. This build addresses issues we saw with the Create Slideshow Workload when testing on Android 5 devices. The tests have not changed, so new scores are comparable with previous BatteryXPRT scores.

Although the patch works on the majority of Android 5 devices, we are continuing to investigate intermittent failures on the Nexus 9. Please see the Monday’s blog post, for details.

Click here to download the new BatteryXPRT installer (317 MB) directly from our site.

For users who have limited bandwidth or trouble accessing the Google Play store, downloading the APK files (16.9 MB total) may make installation easier.

Download the updated BatteryXPRT APK (2.7 MB) directly from our site.

Download the updated BatteryXPRT Tests APK (14.2 MB) directly from our site.

If you have any questions about the update or any other XPRT-related topic, feel free to contact us at BenchmarkXPRTsupport@principledtechnologies.com.

An update for BatteryXPRT 2014 for Android

Eric Hale
By Eric Hale
on December 1, 2014

For those of you in the US, I hope you had a happy Thanksgiving.

A couple of weeks ago, we updated MobileXPRT so that it would run correctly on Android 5 (Android L) devices. Later this week, we will be updating BatteryXPRT as well. The current BatteryXPRT build doesn’t work with Android 5 due to failures of the Create Slideshow workload. This is the same workload failure we fixed with an updated MobileXPRT build.

The new build greatly improves things. We successfully tested the new build on an array of Android 5 and 4.4 devices with no failures. However, we have seen the new build of BatteryXPRT return intermittent errors during the Create Photo Collage and Apply Photo Effects workloads when testing on the Nexus 9.

Because the error on the Nexus 9 is intermittent, it’s possible to get results from some runs. These results are still valid.

We haven’t seen this failure on any device other than the Nexus 9, but cannot guarantee that there aren’t others. If you see any other failures, or have any questions, please contact us.

We’re currently working on a solution for this problem. We will, as always, keep you informed.

A new model

Eric Hale
By Eric Hale
on November 20, 2014

Today we released a new community preview for CrXPRT (CP2). It contains several enhancements and UI changes. It also fixes the problem we discussed in last week’s blog, so CP2 will now correctly execute a rundown test on a system using Chinese language settings.

The most exciting enhancement is that CP2 will let you test battery life without having to put the device into developer mode.  The new Battery Status API, which became available with Chrome 38, makes this possible.

Another enhancement is that results submission is now integrated into the benchmark UI. CrXPRT follows the WebXPRT model, with you having opt-in control over whether the results are published on the PT Web site. However, CrXPRT goes further by allowing you the option to upload more extensive disclosure information, and the option to download results as a text file.

These and other enhancements are covered in more detail in the CrXPRT forum and the user manual. Because this is a community preview, you have to be a community member to download it. However, joining is very easy.

We hope you like the new features in CrXPRT. Let us know what you think!

News about MobileXPRT 2013 and WebXPRT 2015

Today, we’re releasing a new build (v92) of MobileXPRT 2013 at MobileXPRT.com and the Google Play store. This build addresses issues encountered when testing MobileXPRT on Android 5 devices. The tests have not changed, so new scores are comparable with previous MobileXPRT 2013 scores.

Click here to download the new MobileXPRT build directly from our site.

Alternatively, you can download the MobileXPRT 2013 APKs directly. The APKs are small (17.9 MB total) and allow you to download the test content during installation. For users who have trouble accessing the Google Play store, these APKs may make it easier to download the benchmark.

Download the MobileXPRT APK here.
Download the MobileXPRT UX Tests APK here.

Also, today we’re publishing the WebXPRT 2015 Design Overview document for community members. You can find the document on the WebXPRT tab in the Members’ Area. We look forward to your feedback!

If you have any questions or concerns about these or any other XPRT-related topics, feel free to contact us at BenchmarkXPRTsupport@principledtechnologies.com.

The value of diversity

Eric Hale
By Eric Hale
on November 13, 2014

It’s great to hear from community members who are using the XPRTs. Having a pool of users with diverse viewpoints is critical for successful software development. While we try very hard to find problems, there will always be cases we miss.

For example, we talked recently about the challenges of working in a multilingual world. Just this week, Acer reported an interesting bug in the CrXPRT community preview. If your language is set to Chinese, the battery test will estimate the battery life as expected. However, a rundown test will return the message “Cannot calculate total run time.” This does not happen when the language is set to English.

We have verified this problem. In the next week or so, we’ll be releasing a second community preview containing a fix for this and a few other issues.

We’ve talked before about the difficulties of maintaining software in a fast moving world. Late last week, we received a new Nexus 9. It encountered a problem during the MobileXPRT tests, so we fixed the problem and will be releasing a patched build tomorrow.

Don’t forget, as we said last week, we’ll be releasing the WebXPRT 2015 design overview tomorrow. We are looking forward to the feedback from all our community members.

Upcoming experiments

Eric Hale
By Eric Hale
on November 6, 2014

Next week, we’ll be releasing the design overview for WebXPRT 2015. WebXPRT 2013 has been an enormous success, having been run tens of thousands of times.

One of the big improvements we are considering for WebXPRT 2015 is adding experimental tests. A big reason for WebXPRT’s success is that it runs on almost every Web-enabled device. We consider it essential to preserve this broad compatibility. However, there are interesting Web technologies that simply are not available on all devices.

Our proposal is to add experimental tests to WebXPRT. These tests would be optional and would not be included in the Overall score, so WebXPRT would still be able to compare the performance of widely different devices. We are looking at technologies such as Web Workers, WebGL, and pre-compiled JavaScript (asm.js).

In addition to adding experimental tests, we are looking at ways to improve the UI, add automation, add new tests, update old tests, and more!

If you are a community member, you’ll get a notice when the overview is available. We will definitely want to know what you think! If you are not a member, it’s a great time to join.

If you have any thoughts on these ideas, or have ideas of your own, please let us know!

Eric
