BatteryXPRT provides the objective battery life data that shoppers need

Over the last few weeks, we’ve discussed the capabilities and benefits of TouchXPRT and CrXPRT. This week, we’d like to reintroduce readers to BatteryXPRT, our app that evaluates the battery life and performance of Android devices.

Battery life for phones and tablets has improved dramatically over the last several years, to the point where many devices can support continuous use for well over a full work day on a single charge. This improvement is the result of advances in battery hardware technology, increased processor efficiency, and smarter utilization of software services by the operating system. Battery life has increased to some extent for most device categories and price points. However, enough of a range remains between devices at each level that access to objective battery life data is valuable for device shoppers.

Without BatteryXPRT, shoppers must rely on manufacturer estimates or full rundown tests that don’t resemble the types of things we do with our phones and tablets every day. A rundown test that surfs the web continuously for over 15 hours reveals which devices last the longest performing that specific task. It doesn’t tell you which devices last the longest over a full day performing a variety of common activities such as web browsing, watching videos, browsing and editing photos, playing music, and periodically sleeping. During BatteryXPRT’s battery life test, the app executes those same types of tasks and produces a performance score based on the speed with which a device completes each task.

BatteryXPRT provides an intuitive user interface in English and Simplified Chinese, and easy-to-understand results for both battery life and performance. Because your data connection can have a significant effect on battery life, BatteryXPRT runs in airplane mode, connected to the Internet via Wi-Fi, or connected to the Internet through a cellular data connection.

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 configuring your device and kicking off a test. We designed BatteryXPRT 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

The Exploring BatteryXPRT 2014 for Android white paper covers almost every aspect of the benchmark. In it, we explain the guiding concepts behind BatteryXPRT’s development, as well as the benchmark’s structure. We describe the component tests, the differences between the app’s Airplane and Network/Wi-Fi modes, and the statistical processes used to calculate expected battery life.

Three years of the XPRT Weekly Tech Spotlight

Justin Greene
By Justin Greene
on March 14, 2019

February marked the three-year anniversary of the XPRT Weekly Tech Spotlight, and we now have over 150 devices in our Spotlight library! We started the Spotlight to provide consumers with objective information on device hardware and performance, and to provide vendors with a trusted third-party showcase for their gear. Each week, we measure and verify the Spotlight device’s specs ourselves, never relying on vendor-published data. We also test each device with every applicable XPRT benchmark, and publish the data that lets consumers know how a device measures up to its competitors.

Over the past three years, we’ve featured a wide array of devices:

  • 49 phones
  • 28 laptops
  • 26 tablets
  • 24 2-in-1 devices
  • 12 small-form-factor PCs
  • 7 desktops
  • 6 game consoles
  • 6 all-in-ones

 

In addition to a wide variety of device types, we try to include a wide range of vendors. We’ve featured devices from ACEPC, Acer, Alcatel, Alienware, Amazon, Apple, ASUS, Barnes and Noble, BlackBerry, BLU, CHUWI, Dell, Essential, Fujitsu, Fusion5, Google, Honor, HP, HTC, Huawei, Intel, LeEco, Lenovo, LG, Microsoft, MINIX, Motorola, Nokia, NVIDIA, OnePlus, Razer, Samsung, Sony, Syber, Xiaomi, and ZTE.

XPRT Spotlight is a great way for device vendors and manufacturers to share PT-verified specs and test results with buyers around the world. We test many of the devices that appear each year and will test—at no charge—any device a manufacturer or vendor sends us. If you’d like us to test your device, please contact us at XPRTSpotlight@PrincipledTechnologies.com.

There’s a lot more to come for the XPRT Spotlight, and we’re constantly working on new features and improvements for the page. Are there any specific devices or features that you would like to see in the Spotlight? Let us know.

More, faster, better: The future according to Mobile World Congress 2019

Mark Van Name

More is more data, which the trillions of devices in the coming Internet of Things will be pumping through our air into our (computing) clouds in hitherto unseen quantities.

Faster is the speed at which tomorrow’s 5G networks will carry this data—and the responses and actions from our automated assistants (and possibly overlords).

Better is the quality of the data analysis and recommendations, thanks primarily to the vast army of AI-powered analytics engines that will be poring over everything digital the planet has to say.

Swimming through this perpetual data tsunami will be we humans and our many devices, our laptops and tablets and smartphones and smart watches and, ultimately, implants. If we are to believe the promise of this year’s Mobile World Congress in Barcelona—and of course I do want to believe it, who wouldn’t?—the result of all of this will be a better world for all humanity, no person left behind. As I walked the show floor, I could not help but feel and want to embrace its optimism.

The catch, of course, is that we have a tremendous amount of work to do between where we are today and this fabulous future.

We must, for example, make sure that every computing node that will contribute to these powerful AI programs is up to the task. From the smartphone to the datacenter, AI will end up being a very distributed and very demanding workload. That’s one of the reasons we’ve been developing AIXPRT. Without tools that let us accurately compare different devices, the industry won’t be able to keep delivering the levels of performance improvements that we need to realize these dreams.

We must also think a lot about how to accurately measure all other aspects of our devices’ performance, because the demands this future will place on them are going to be significant. Fortunately, the always evolving XPRT family of tools is up to the task.

The coming 5G revolution, like all tech leaps forward before it, will not come evenly. Different 5G devices will end up behaving differently, some better and some worse. That fact, plus our constant and growing reliance on bandwidth, suggests that maybe the XPRT community should turn its attention to the task of measuring bandwidth. What do you think?

One thing is certain: we at the Benchmark XPRT Development Community have a role to play in building the tools necessary to test the tech the world will need to deliver on the promise of this exciting trade show. We look forward to that work.

By Justin Greene
on October 26, 2018

In last week’s blog, we discussed why we now consider full BatteryXPRT rundown tests to be the most accurate and why we’re releasing a new build (v110) that increases the default BatteryXPRT test from 5.25 hours (seven iterations) to 45 hours (60 iterations). We also built v110 using Android Studio SDK 27, in order to bring BatteryXPRT up to date with current Android standards. Today, we’ve posted the new build on BatteryXPRT.com and in the Google Play Store, and we’ve also published an updated user manual. Please contact us if you have any questions about BatteryXPRT testing.

Updates on HDXPRT 4 and MobileXPRT 3

Justin Greene
By Justin Greene
on October 11, 2018

There’s a lot going on with the XPRTs, so we want to offer a quick update.

On the HDXPRT 4 front, we’re currently testing community preview candidate builds across a variety of laptops and desktops. Testing is going well, but as is often the case prior to a release, we’re still tweaking the code as necessary when we run into bugs. We’re excited about HDXPRT 4 and look forward to the community seeing how much faster and easier to use it is than previous versions. You can read more about what’s to come in HDXPRT 4 here.

On the MobileXPRT 3 front, proof-of-concept testing for the new and updated workloads went well, and we’re now working to implement the new UI. Below, you can see a mockup of the new MobileXPRT 3 start screen for phones. The aesthetic is completely different than MobileXPRT 2015, and is in line with the clean, bright look we used for WebXPRT 3 and HDXPRT 4. We’ve made it easy to select and deselect individual workloads by tapping the workload name (deselected workloads are grayed out), and we’ve consolidated common menu items into an Android-style taskbar at the bottom of the screen. Please note that this is an early view and some aspects of the screen will change. For instance, we’re certain that the final receipt-scanning workload won’t be called “Optical character recognition.”

We’ll share more information about HDXPRT 4 and MobileXPRT 3 in the coming weeks. If you have any questions about HDXPRT or MobileXPRT, or would like to share your ideas, please get in touch!

Notes from the lab: choosing a calibration system for MobileXPRT 3

Justin Greene
By Justin Greene
on October 4, 2018

Last week, we shared some details about what to expect in MobileXPRT 3. This week, we want to provide some insight into one part of the MobileXPRT development process, choosing a calibration system.

First, some background. For each of the benchmarks in the XPRT family, we select a calibration system using criteria we’ll explain below. This system serves as a reference point, and we use it to calculate scores that will help users understand a single benchmark result. The calibration system for MobileXPRT 2015 is the Motorola DROID RAZR M. We structured our calculation process so that the mean performance score from repeated MobileXPRT 2015 runs on that device is 100. A device that completes the same workloads 20 percent faster than the DROID RAZR M would have a performance score of 120, and one that performs the test 20 percent more slowly would have a score of 80. (You can find a more in-depth explanation of MobileXPRT score calculations in the Exploring MobileXPRT 2015 white paper.)

When selecting a calibration device, we are looking for a relevant reference point in today’s market. The device should be neither too slow to handle modern workloads nor so fast that it outscores most devices on the market. It should represent a level of performance that is close to what the majority of consumers experience, and one that will continue to be relevant for some time. This approach helps to build context for the meaning of the benchmark’s overall score. Without that context, testers can’t tell whether a score is fast or slow just by looking at the raw number. When compared to a well-known standard such as the calibration device, however, the score has more informative value.

To determine a suitable calibration device for MobileXPRT 3, we started by researching the most popular Android phones by market share around the world. It soon became clear that in many major markets, the Samsung Galaxy S8 ranked first or second, or at least appeared in the top five. As last year’s first Samsung flagship, the S8 is no longer on the cutting edge, but it has specs that many current mid-range phones are deploying, and the hardware should remain relevant for a couple of years.

For all of these reasons, we made the Samsung Galaxy S8 the calibration device for MobileXPRT 3. The model in our lab has a Qualcomm Snapdragon 835 SoC, 4 GB of RAM, and runs Android 7.0 (Nougat). We think it has the balance we’re looking for.

If you have any questions or concerns about MobileXPRT 3, calibration devices, or score calculations, please let us know. We look forward to sharing more information about MobileXPRT 3 as we get closer to the community preview.
