What are Smartphone
Battery Life Ratings and Performance Scores?
Our SmartViser technology experts use their years of experience to simulate real-life general phone usage.
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 represent lower test performance results, and those nearer 100 indicate the results from the best-performing ones.
Why Our Smartphone
Testing Is Simply Unique?
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
How are Battery Life Ratings and Performance Score Calculated?
ViserMark tests hundreds of Smartphones every year to find the best-performing ones. We are pleased to introduce our Battery Performance Label within our strict testing protocol.
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.
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 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.
ViserMark Labels
Being involved in various projects that aimed to create Energy Efficiency policies, 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, some incredibly good battery performance ratings can help you choose the right smartphone.
