How The ViserMark Labels Were Created

ViserMark was created by SmartViser in 2020. With the help of the SmartViser technology, years of experience of their experts, and working several years with smartphone manufacturers, SmartViser identified a gap in the market for an industry label presenting mobile phone battery performance. Also, at this time, in consumer electronics, the only way to check battery performance was through media review sites. With everyone using their own way of accessing battery performance, there was a lack of consistency and some very subjective results.  


ViserMark simulated real-life general smartphone usage.  The strict testing protocol provided clear smartphone battery performance results that could be represented visually on labels. For example, battery life results were translated from mAh (battery capacity) into Days and Hours of Use, showing how long a smartphone battery is expected to last.

​With labels emerging in many different industries, such as home appliances and automotive, the visuality of information ensured consumers could make the right choices and brands communicate their message.  The ViserMark Labels help smartphone users make informed decisions before deciding which mobile phone to purchase, often saving time instead of searching through several phone reviews and comparisons. ​At the same time, smartphone manufacturers find it increasingly difficult to clearly communicate their value in battery performance in clear, non-technical terms and jargon, ViserMark Labels helped them differentiate.

How Are The ViserMark Labels Calculated 

ViserMark tests hundreds of smartphones every year to find the best-performing ones. Using various criteria, collating test data over time has enabled established benchmarks to be used to evaluate a smartphone's performance.

SmartViser Device Testing

​Our testing criteria include everyday daily life activities, such as:

  • Making calls

  • Using the Web

  • Video and music streaming

  • Gaming

  • Utilising social networks

  • Picture & video capture

  • Standby quality

A Comprehensive Range ViserMark Labels

ViserMark offers a comprehensive range of informative, valuable labels to show all the battery performance results. 

Battery Performance - How does this Smartphone compare with others?

This is a Performance Score given between 0 and 100. It reflects the performance based on independent, repeatable, and rigorous testing. It is calculated using Battery Life, Power Efficiency and Charging results. 


Often finding information about smartphones is difficult. ViserMark can now provide relevant and helpful information.

ViserMark Label showing Smartphone Battery Performance Score of 62/100
ViserMark Labe showing Smartphone Battery Life of 2 Days or 45 Hoursl
ViserMark Label showing a Smartphone Charging Time of 1 hour and 42 minutes
ViserMark Label showing Smartphone Battery Efficiency of 3 out of 5 leaves
ViserMark Label showing Smartphone Annual Energy Consumption of 2.5 kWh/Annum

Battery Life - How long will this smartphone battery last?

This is expressed in "Hours and Days of Use" and reflects the time in days that a smartphone can be used from a full charge. The ViserMark Battery Label translates mAh (meaning milliamp Hours), commonly used to measure the energy capacity of a Smartphone battery, into more meaningful. 

Battery Charging Time - How long will this smartphone take to charge?

Charging different types and sizes of smartphone batteries takes additional time. This is expressed in Hours and Minutes.

Power Efficiency - How power-efficient is this smartphone? 

It simply means maximising the performance of a smartphone while reducing the amount of energy it consumes, with minimal impact on battery life. It is calculated using Battery Life and Battery Capacity. This is expressed in "Leaves" and reflects a rating between 1 being the least and 5 being the most power-efficient.  

With smartphone manufacturers using more sustainable methods so devices have a minimal environmental impact, this information is now much more relevant.  

Annual Energy Consumption - Will this smartphone use much energy?


Being involved in various projects that aimed to create Energy Efficiency policies, ViserMark introduced a new label in 2023. The Annual Energy Consumption Label, measured in kWh, will display, for the first time, an objective benchmark across all devices on the expected annual electricity consumption. 

Find out how the ViserMark Labels allow smartphone users to review battery life ratings and performance scores.
For smartphone manufacturers and developers, learn how they help improve the "Quality of Experience" (QoE), which enables the translation of technical specifications into straightforward smartphone user benefits. Finally, to raise awareness of the ViserMark Labels within the Telecommunications industry, ViserMark works with media professionals, journalists, editors, freelancers, and bloggers to share the latest battery performance results.​
