What are Smartphone
Battery Life Ratings and Performance Scores?

Our SmartViser technology experts use their years of experience to simulate real day life general usage of how a phone is used.
 
The overall Battery Performance Score is now a global score
taking calculations from Battery Life, Power Efficiency and Charging Times.
 
The Smartphone test results are converted to a Score between 0 and 100.
0 and above represents lower test performance results and those nearer 100 indicate the results from best-performing ones.  

Why Our Smartphone
Testing Is Simply Unique?

Our testing criteria include common daily life activities, such as:

  • Making calls

  • Using the Web

  • Video and music streaming

  • Gaming

  • Utilising social networks

  • Picture & video capture

  • Standby quality

ViserMark Our Smartphone Testing Is Simply Unique. Using a viSer bot, real user actions can be stimulated on a smartphone.
ViserMark Battery Life Ratings and Performance Score Calculated

How are Battery Life Ratings and Performance Score Calculated?

 

ViserMark tests hundreds of Smartphones every year to find the best-performing ones. Within our strict testing protocol, we are pleased to introduce our Battery Performance Label.

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 useful information.

ViserMark Battery Charging Time different amount of time to charge different types and sizes of Smartphone batteries
ViserMark Power Efficiency label maximising the performance of a Smartphone while reducing the amount of energy it consumes

Battery Life - How long will this Smartphone battery last?

This is expressed in “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 TimeHow long will this Smartphone take to charge?

It takes a different amount of time to charge different types and sizes of Smartphone batteries. This is expressed in Hours and Minutes.

Power EfficiencyHow 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 minimal impact on the environment, this information is now so much more relevant.  

ViserMark Labels

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. 

Smartphone Reviews and Comparisons

We have tested the battery life and performance of many smartphones.

Having compiled many mobile phone reviews, there are some incredibly good battery performance ratings that can help you to choose a smartphone that is just right for you.
