How Do We

Test Smartphones?

Our primary objective is to support Smartphone manufacturers in improving their products' Quality of Experience and offer superior value to their customers.


As an independent testing environment, SmartViser measures and validates key areas of user experience, enabling Smartphone manufacturers to translate technical specifications into straight forward customer benefits.

ViserMark has created one of the first labels to display the battery life performance of a Smartphone. It shows the most important outcomes as an easy-to-understand view of battery life and performance.

What's Important About A ViserMark

Label Score? 

Our first label measures battery performance, translating mAh into direct battery life scores. Indeed, battery life is one of the key areas reviewed by customers when choosing a new Smartphone.

We can deliver an official rating and score using our highly specialised, state-of-the-art lab equipment.  Our SmartViser technology experts use their years of experience to simulate real day life general usage.  

The ViserMark Label is designed to help an end-user to quickly work out whether a smartphone is right for them. Alternatively, it can enable Smartphone manufacturers to translate technical specifications into straight forward end user benefits, that provides a valuable marketing asset.
