Smartphones Reviews For Users
Ratings and Comparisons of Tested Devices
ViserMark have designed and will continue to develop a comprehensive range of ViserMark Labels. We do understand there is a plethora of technical information that often makes it difficult to grasp exactly how this will impact “you” with your day-to-day smartphone usage.
Choosing The Perfect Smartphone For You
Buying a new smartphone can be a little daunting, especially with so many to compare and consider.
You have told us that smartphone battery life and performance are top priorities, so it's essential you know how long you can expect a battery to last with real-life usage or how long it will take to charge.
Make An Informed Choice
Smartphones are very much part of our daily lives and some people simply cannot function without one. When faced with buying a new smartphone, having to wade through the range of devices on offer, and make sense of the jargon and the specifications - can be quite overwhelming.
We want to share with you all our latest smartphone test results and reviews. When researching your next smartphone, our ViserMark Labels will keep you well informed of battery life results, which is one of the most important considerations when buying a smartphone.


Smartphones Tried and Tested
SmartViser, as a recognised device test expert, is asked to test more than 100 smartphones every year, supporting smartphone manufacturers in improving their development efforts.
All smartphones are evaluated in a dependent testing environment under strictly controlled test conditions. Test results and scores are then translated into ViserMark Labels for straightforward smartphone user understanding and benefits.
ViserMark Labels - Battery Performance Insights
For buyers who are looking to purchase a smartphone, the only information available to them is either the battery capacity in milliamp hours or more commonly abbreviated mAh or some endurance score that is based on a very specific usage like standby or talk time.
We have also seen over the years that each smartphone Manufacturer and Media have their own way of assessing battery performance considering different criteria and, on some occasions, tests are performed in perfect mobile network conditions which none of us experience.
The ViserMark Labels have been designed to provide relevant and useful information.
This comprehensive range of labels, simply can help you to understand smartphone battery life and performance.
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, Power Efficiency and Charging results that amount to the total 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 accuarte 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 battery capitcity 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.

ViserMark introduced the first Battery Efficiency Label in the world to show the battery energy efficiency of the device. It is calculated using Battery Life and Battery Capacity. This is expressed in “Leaves" and reflects a rating between 1 being least and 5 being the most power-efficient.
With smartphone manufacturers using more sustainable methods, so devices have minimal impact on the environment, this information is now so much more relevant.

Being involved in various projects that looked to create policies on Energy Efficiency, ViserMark will be introducing 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.
