Success Metrics


P40 Pro is the 2020 version of the P flagship range from Huawei. It holds a beautiful quad curved screen, a best in class Leica camera setup, a very powerful Kirin 990 as long with a 4200 mAh battery. This capacity sounds a little low compared with flagship competition. But Huawei P serie is known to be very power efficient, let’s see how P40 Pro will perform on viSerMark protocol.

Testing Results

When preparing P40 Pro to start viSerMark protocol we had one very first question, what will be impact on lack of google services on this device, can it still perform viSerMark protocol? Well, we have to say that it has been very easy to find out usual apps used for viSerMark and finally integrating HMS instead of GMS didn’t impact at all test execution. P40 Pro did execute exactly same protocol as smartphones integrating the google services.

We have tested P40 Pro with 2 different screen refresh rate: 60 Hz or 90 Hz, this last setting means that the smartphone will adjust refresh rate depending on displayed content. As a result we have been very positively surprised to see P40 Pro exceeding the 2 days ranking even with 90Hz auto setting. When setting refresh rate to 60 Hz then P40 Pro gives 2 hours extra time, good but not changing the life. The overall score provided is an average of the two different screen refresh rates:

Switching between 60Hz to 90Hz will not widely change battery life. 90 Hz is only turned on when necessary to improve customer experience.


P40 Pro achieved a very good viSerMark score scoring 212 with a final ranking of 2 Days. This is a very good performance with such a high end setup powered with a 4200 mAh battery.

ViserMark tests are performed with the strictest protocol in a controlled environment to ensure repetition and consistency powered and automated by SmartViser’s test automation solution viSer. The automation test includes a variety of user actions from calls to social media and periods of standby times.
