Smartphone Battery Efficiency Ratings
Top Ten Best Smartphones 2022 - 2024

Smartphone power efficiency refers to the ability of a smartphone to perform optimally while using less power, which directly impacts battery life and device usage. All chipsets are designed for high performance and minimal power consumption, with continuous improvements to balance performance and energy efficiency. This includes managing background processes and app organisation to enhance resource allocation and minimise power consumption. 
ViserMark's Battery Efficiency Label rates devices' power efficiency on a scale of 1 to 5 Leaves. It's the first of its kind in the world, calculated using Battery Life and Capacity to help customers compare devices.

The smartphone power efficiency can vary among different smartphone models and manufacturers.

The hardware components of a smartphone, such as the processor (CPU), graphics processing unit (GPU), and modem, play a significant role in power efficiency. Advanced chipsets and processors are designed to deliver high performance while consuming minimal power. Manufacturers often optimise the hardware to strike a balance between performance and energy efficiency.

Also, the operating system (OS) and software play a crucial role in power efficiency. Smartphone manufacturers invest in optimising the software to minimise power consumption by managing background processes, app management, and resource allocation. Regular software updates often include power-saving optimisations to improve efficiency.
