Smartphone Reviews and Testing 

ViserMark provides comprehensive, informative results as part of our smartphone testing protocol. Common metrics and benchmarks are used to evaluate a smartphone's performance. This includes further information on device battery life, charging times, power efficiency and the latest test results for annual power consumption. Our team collates the results into valuable ratings represented by the ViserMark Labels to help assess smartphone performance.

The comprehensive range of labels ViserMark Labels have been designed to provide relevant and useful information.    

The Battery Performance Label shows a score between 0 and 100. It reflects the performance based on independent, repeatable, and rigorous testing. Using various testing criteria, measured using real-life scenarios and live networks, results are collated with calculations from battery life, battery capacity, and energy efficiency, resulting in a total battery performance score.

ViserMark introduced the first Battery Life Label to show Days and Hours of use. The metrics inform you of how long a device is expected to last if tested over the day and night with real-life user activities from a full charge. A recent improvement to the label provides more accurate information on how long the device will last in hours.

Mobile charging times are displayed on the Battery Charging Label.  The times often vary depending on the battery capacity of the smartphone. Charging technology has evolved at a pace and has helped to reduce charging times considerably.  This is expressed in Hours and Minutes.

The Battery Efficiency Label by ViserMark is the world's first rating system that displays a device's battery energy efficiency. It is determined by combining battery life and capacity and is represented by "Leaves" on a scale of 1 to 5, with 5 being the most power-efficient. This information is particularly important now that smartphone manufacturers are adopting eco-friendly approaches to minimize environmental impact.

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

ViserMark Label - Smartphone Battery Life showing 1 hour and 42 minutes
ViserMark Label - Smartphone Battery Efficiency showing 3 out of 5 leaves
ViserMark Label - Smartphone Annual Energy Consumption showing 2.5kWh/Annum
ViserMark Label - Smartphone Battery Life showing 2 Days Use or 45 Hours
