Planning the next version of MobileXPRT

We’re in the early planning stages for the next version of MobileXPRT, and invite you to send us any suggestions you may have. What do you like or not like about MobileXPRT? What features would you like to see in a new version?

When we begin work on a new version of any XPRT, one of the first steps we take is to assess the benchmark’s workloads to determine whether they will provide value during the years ahead. This step almost always involves updating test content such as photos and videos to more contemporary file resolutions and sizes, and it can also involve removing workloads or adding completely new scenarios. MobileXPRT currently includes five performance scenarios (Apply Photo Effects, Create Photo Collages, Create Slideshow, Encrypt Personal Content, and Detect Faces to Organize Photos). Should we stick with these five or investigate other use cases? What do you think?

As we did with WebXPRT 3 and the upcoming HDXPRT 4, we’re also planning to update the MobileXPRT UI to improve the look of the benchmark and make it easier to use.

Crucially, we’ll also build the app using the most current Android Studio SDK. Android development has changed significantly since we released MobileXPRT 2015 and apps must now conform to stricter standards that require explicit user permission for many tasks. Navigating these changes shouldn’t be too difficult, but it’s always possible that we’ll encounter unforeseen challenges at some point during the process.

Do you have suggestions for test scenarios that we should consider for MobileXPRT? Are there existing features we should remove? Are there elements of the UI that you find especially useful or have ideas for improving? Please let us know. We want to hear from you and make sure that MobileXPRT continues to meet your needs.

Decisions, decisions

Back in April, we shared some of our initial ideas for a new version of WebXPRT, and work on the new benchmark is underway. Any time we begin the process of updating one of the XPRT benchmarks, one of the first decisions we face is how to improve workload content so it better reflects the types of technology average consumers use every day. Since benchmarks typically have a life cycle of two to four years, we want the benchmark to be relevant for at least the next couple of years.

For example, WebXPRT contains two photo-related workloads, Photo Effects and Organize Album. Photo Effects applies a series of effects to a set of photos, and Organize Album uses facial recognition technology to analyze a set of photos. In both cases, we want to use photos that represent the most relevant combination of image size, resolution, and data footprint possible. Ideally, the resulting image sizes and resolutions should differentiate processing speed on the latest systems, but not at the expense of being able to run reasonably on most current devices. We also have to confirm that the photos aren’t so large as to impact page load times unnecessarily.

The way this strategy works in practice is that we spend time researching hardware and operating system market share. Given that phones are the cameras that most people use, we look at them to help define photo characteristics. In 2017, the most widespread mobile OS is Android, and while reports vary depending on the metric used, the Samsung Galaxy S5 and Galaxy S7 are at or near the top of global mobile market share. For our purposes, the data tells us that choosing photo sizes and resolutions that mirror those of the Galaxy line is a good start, and a good chunk of Android users are either already using S7-generation technology, or will be shifting to new phones with that technology in the coming year. So, for the next version of WebXPRT, we’ll likely use photos that represent the real-life environment of an S7 user.

I hope that provides a brief glimpse into the strategies we use to evaluate workload content in the XPRT benchmarks. Of course, since the BenchmarkXPRT Development Community is an open development community, we’d love to hear your comments or suggestions!

Keeping up with the latest Android news

Ars Technica recently published a deep-dive review of Android 8.0 (Oreo) that contains several interesting tidbits about what the author called “Android’s biggest re-architecture, ever.” After reading the details, it’s hard to argue with that assessment.

The article’s thorough analysis includes a list of the changes Oreo is bringing to the UI, notification settings, locations service settings, and more. In addition to the types of updates that we usually see, a few key points stand out.

  • Project Treble, a complete reworking of Android’s foundational structure intended to increase the speed and efficiency of update delivery
  • A serious commitment to eliminating silent background services, giving users more control over their phone’s resources, and potentially enabling significant gains in battery life
  • Increased machine learning/neural network integration for text selection and recognition
  • A potential neural network API that allows third-party plugins
  • Android Go, a scaled-down version of Android tuned for budget phones in developing markets


There’s too much information about each of the points to discuss here, but I encourage anyone interested in Android development to check out the article. Just be warned that when they say “thorough,” they mean it, so it’s not exactly a quick read.

Right now, Oreo is available on only the Google Pixel and Pixel XL phones, and will not likely be available to most users until sometime next year. Even though widespread adoption is a way off, the sheer scale of the expected changes requires us to adopt a long-term development perspective.

We’ll continue to track developments in the Android world and keep the community informed about any impact that those changes may have on MobileXPRT and BatteryXPRT. If you have any questions or suggestions for future XPRT/Android applications, let us know!

MobileXPRT: evaluate the performance of your Android device

Justin Greene

on July 27, 2017

We recently discussed the capabilities and benefits of TouchXPRT, CrXPRT, BatteryXPRT, and HDXPRT. This week, we’re focusing on MobileXPRT, an app that evaluates how well an Android device handles everyday tasks. Like the other XPRT family benchmarks, MobileXPRT is easy to use. It takes less than 15 minutes to run on most devices, runs relatable workloads, and delivers reliable, objective, and easy-to-understand results.

MobileXPRT includes five performance scenarios (Apply Photo Effects, Create Photo Collages, Create Slideshow, Encrypt Personal Content, and Detect Faces to Organize Photos). By default, the benchmark runs all five tasks and reports individual workload scores and an overall performance score.

MobileXPRT 2015 is the latest version of the app, supporting both 32-bit and 64-bit hardware running Android 4.4 or higher. To test systems running older versions of Android, or to test 32-bit performance on a 64-bit system, you can use MobileXPRT 2013. The results of the two versions are comparable.

MobileXPRT is a useful tool for anyone who wants to compare the performance capabilities of Android phones or tablets. To see test results from a variety of systems, go to MobileXPRT.com and click View Results, where you’ll find scores from many different Android devices.

If you’d like to run MobileXPRT:

Simply download MobileXPRT from MobileXPRT.com or the Google Play Store. The full installer package on MobileXPRT.com, containing both app and test data, is 243 MB. You may also use this link to download the 18 MB MobileXPRT app file, which will download the test data during installation. The MobileXPRT user manual provides instructions for configuring your device and kicking off a test.

If you’d like to dig into the details:

Check out the Exploring MobileXPRT 2015 white paper. In it, we discuss the MobileXPRT development process and details of the individual performance scenarios. We also explain exactly how the benchmark calculates results.

If you’d like to dig even deeper, the MobileXPRT 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 MobileXPRT before, give it a shot and let us know what you think!

Notes from the lab

This week’s XPRT Weekly Tech Spotlight featured the Alcatel A30 Android phone. We chose the A30, an Amazon exclusive, because it’s a budget phone running Android 7.0 (Nougat) right out of the box. That may be an appealing combination for consumers, but running a newer OS on inexpensive hardware such as what’s found in the A30 can cause issues for app developers, and the XPRTs are no exception.

Spotlight fans may have noticed that we didn’t post a MobileXPRT 2015 or BatteryXPRT 2014 score for the A30. In both cases, the benchmark did not produce an overall score because of a problem that occurs during the Create Slideshow workload. The issue deals with text relocation and significant changes in the Android development environment.

As of Android 5.0, on 64-bit devices, the OS doesn’t allow native code executables to perform text relocation. Instead, it is necessary to compile the executables using position-independent code (PIC) flags. This is how we compiled the current version of MobileXPRT, and it’s why we updated BatteryXPRT earlier this year to maintain compatibility with the most recent versions of Android.

However, the same approach doesn’t work for SoCs built with older 32-bit ARMv7-A architectures, such as the A30’s Qualcomm Snapdragon 210, so testers may encounter this issue on other devices with low-end hardware.

Testers who run into this problem can still use MobileXPRT 2015 to generate individual workload scores for the Apply Photo Effects, Create Photo Collages, Encrypt Personal Content, and Detect Faces workloads. Also, BatteryXPRT will produce an estimated battery life for the device, but since it won’t produce a performance score, we ask that testers use those numbers for informational purposes and not publication.

If you have any questions or have encountered additional issues, please let us know!

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

Justin Greene
By Justin Greene
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!

BatteryXPRT 2014 for Android Training Course

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.
