ViserMark has been created by SmartViser, the founder of the innovative smartphone test solution called viSer, in 2020. 

Working for several years with Smartphone Manufacturers, we have identified a gap in the market for an industry label presenting mobile phone Battery Life Ratings and Performance Scores.

Before deciding which mobile phone to purchase, smartphone users must plough through several phone reviews and comparisons to make their choice.

At the same time, Smartphone Manufacturers find it increasingly difficult to clearly communicate their value in battery life performance in clear, non-technical terms and jargon. 

ViserMark provides clear smartphone ratings and scores that translate mAh (battery capacity) into Days of Use, showing how long a smartphone battery is expected to last.

How We Test Smartphones.png








Smartphones have become essential to modern life due to their versatility and usefulness. Smartphones have transformed how we live and work, making our lives more connected, productive, and convenient. Also, smartphone users have become more demanding and expect fast processors, superior battery performance, robust and reliable devices, and even entry-tier ones.


As the smartphone industry continues to boom, manufacturers face several challenges in their quest for innovation, product differentiation, and cost-effectiveness without compromising QoE (Quality of Experience) and QoS (Quality of Service). The trend in smartphone battery technology has been towards higher energy density, longer lifespan, and faster charging times. Manufacturers are continually researching and developing new materials and techniques to improve battery performance and address concerns around safety and environmental impact.

​Test scenarios need to be continuously updated to ensure comprehensive coverage on all Radio Technologies, and testing needs to be performed in a maximum of network infrastructures to ensure interoperability. Both activities require heavy resources and time, shrinking even further the profit margins.

Many customers use our proven test automation solutions, like Device Validation and 5G Testing, learn more about what has made them successful. ​​
