Bringing You Smartphone
Battery Life and Performance
Labels and Reviews
Our mission is to positively make it easier
to understand Battery Life Ratings
and Performance Scores
when choosing or buying a smartphone
- for a clearer more informed decision.
Our unique ViserMark Labels are the first to display official smartphone Battery Life Ratings and Performance Scores. So depending on your daily usage and how you use your smartphone, battery life still remains one of the most important considerations when buying a smartphone.
ViserMark tests hundreds of smartphones every year to find the best-performing ones. Within our strict, repeatable and rigorous testing protocol, there is no room for error. All smartphones are tested the same, so you have all the right information, just at the right time, when researching and comparing.
Often finding information about smartphones is difficult.
ViserMark can now provide visual labels displaying relevant and useful information.
Introducing The Battery Performance Label
The Battery Performance Label shows a score given between 0 and 100.
Using various testing criteria, measured using real-life scenarios and live networks, results are collated with calculations from Battery Life, Power Efficiency and Charging results that amount to the total score.
Comprehensive Reviews Using ViserMark Labels
As part of our testing protocol, we are able to bring to you a comprehensive set of test results. This can also provide even further information on battery life, battery charging, and power efficiency. We have collated these into useful ratings that will help you to see where a Battery Performance Score is impacted or where certain smartphone features are particularly more important to you than others.
Our ViserMark Labels are used within our smartphone reviews, keeping you up-to-date with the latest results. Also, additional information can be found in our comprehensive Smartphone Ranking Tables with the Top 10 mobile devices highlighted for Battery Performance, Battery Life, Battery Charging Times, Battery Power Efficiency and Annual Energy Consumption.
