Time for a merger of equals?

As I said last week, we’re working on the design document for the new version of MobileXPRT, and we expect to have it out in the next couple of weeks. We have several ideas we’re pretty excited about.

One of the ideas we’ve been considering is merging BatteryXPRT and MobileXPRT into a single benchmark. This would be similar to what we’ve done with CrXPRT, which has tests for both battery life and performance. As with CrXPRT, you’d be able to run either test, and you could get performance and battery life for a device in a single day using a single benchmark.

If we as the community do decide to merge the benchmarks, there will be a lot to think about. For example, MobileXPRT is unaware whether it’s connected to the Internet, while BatteryXPRT not only detects how it’s connected, but selects the appropriate Airplane mode or Network-Wifi Mode test. And, of course, we’d have to figure out what to call it.

What do you think about merging the two benchmarks? Would it make your life simpler? What other features would you like to see in the new MobileXPRT? This is the time to speak up!

It’s been a show to watch!

Mobile World Congress 2015 (MWC) has been happening this week in Barcelona. There have been lots of cool phones and tablets, of course, but also there has also been a lot of other cool stuff. From smart watches, foldable keyboards, and 200 GB SD cards to “privacy glasses,” electric bicycles, and even furniture from IKEA, this has definitely been a show to watch.

As you know, Bill is our man in Barcelona. If you read Bill’s blog, you know he lives for this sort of stuff. He’s also been meeting with vendors and having great conversations about the XPRTs.

Last week I mentioned that Bill took a great-looking handout to MWC with him. For those who have been wondering what a megaphone had to do with anything, here’s what the front and back look like.

Let the world know blue Let the world know red

Even though MWC hasn’t ended yet, we’re already deep into preparations for Intel Developer Forum 2015 – Shenzhen. We’ll have more to say about that in the weeks to come.

In other news, we released a new build of BatteryXPRT 2014, v103. The build fixes a problem reported by a reviewer testing the LG G3. Scores from this build are comparable with previous BatteryXPRT scores. Click here for more details.

An updated BatteryXPRT 2014 build is available

Today we’re releasing a new build of BatteryXPRT 2014 (v103) at BatteryXPRT.com and the Google Play store. The build fixes a problem reported by a reviewer testing the LG G3. The device was going to sleep during the performance test, and causing BatteryXPRT to crash after waking up. We’ve seen this problem only on the LG G3, but it may occur on other devices as well.

The new BatteryXPRT build prevents the device from entering a sleep state. Scores from this build are comparable with previous BatteryXPRT scores.

Staying Awake

Here in the Eastern US, we’re in a deep freeze. Wherever you are, I hope you’re comfortable and safe.

Tomorrow, we’ll be releasing a patch to MobileXPRT. This patch fixes a problem first reported in a Tom’s Hardware review of the LG G3. The reviewer was not able to get MobileXPRT to run to completion on that device. We looked at the problem and found that the LG G3 was going to sleep during the performance test, and that when the device woke up, MobileXPRT caught an exception and crashed. This problem appeared to be specific to the LG G3, but could occur on other devices as well.

When we changed MobileXPRT to keep the screen active during the run of the app, the benchmark ran on LG G3 without any issues. We’ve tested this fix on our entire test bed and found that it works well. As always, the results remain comparable with previous versions.

We’ve made the same change in BatteryXPRT and are testing it now. Testing BatteryXPRT takes more time than testing MobileXPRT, but we hope to release the patch soon.

In other news, Bill is going to Mobile World Congress in Barcelona, March 2-4, and he would love to meet you. If you are also planning to go, let us know.

An updated CrXPRT 2015 build is available

Today we’re releasing a new build of CrXPRT 2015 (v1.0.2) in the Chrome Web Store. The updates included in this build correct the handling of outlier scores for individual workloads, check the duration of each battery-life test iteration, and introduce a check to ensure that the system is not plugged in during battery-life testing. The tests have not changed, and the method of calculating the overall score and battery-life score is the same, so the main scores are comparable with previous CrXPRT scores.

We published the update today in the Chrome Web Store as of 3:00 PM EST, but it may take some time for the update to appear on your system. You may have to manually approve the update notice when it appears on your system.

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

Polishing the chrome

Early next week, we’ll be releasing an update for CrXPRT that addresses a couple of issues. First, the individual workload scores were not always discarding outliers correctly, which could have had a small effect on those scores. The update handles outliers correctly. Because the overall score is calculated separately from the individual workload scores, this change does not affect the overall score or battery life score, and results from previous builds are still comparable.

The update also checks the duration for each battery life test iteration. This helps detect conditions that could invalidate the test, such as someone manually putting a test system to sleep.

Finally, the update checks between iterations to see if the Chromebook is plugged in during the test. If so, CrXPRT will report an error and stop the test. This can potentially save time that would otherwise be lost on an invalid run.

These are small changes, but they will help make CrXPRT a more robust benchmark.

In other news, we’ve been asking members of the community if they would care to share their experiences and thoughts on the blog.  We’re delighted that people are interested, and we’ve already received our first guest post that we’ll be publishing in the next couple of weeks. In the meantime, if you’d like to write a post, or just want to share your thoughts on the XPRTs, please let us know!
