DXOMARK: Specs like mAh and Watt do not indicate true battery performance

In its latest findings, DXOMARK, the French parameters company, has said that battery performance of a smartphone depends on a combination of factors including the choice of hardware components and power management software optimization.

In their findings, the Samsung Galaxy M51 emerged as the top ranked device for its overall performance. The Find X3 range by OPPO finds top places in the ranking table for charging, enabling users to charge ultra-fast from 0-80%. Apple’s iPhone 12 Pro Max finds itself way ahead of competition in terms of efficiency.

Known worldwide for the tests and scores of camera, audio and display quality of consumer electronics, DXOMARK announced a new score for smartphone battery experience.

DXOMARK has developed a comprehensive test protocol for smartphone battery. The proprietary battery test protocol covers a wide range of common real-life uses smartphones including social media, communication, and multimedia applications.

DXOMARK’s Battery test protocol, evaluates the entire battery experience and quantifies 3 main areas; Autonomy (how long a charge lasts, for various intensity of use), Charging (how long it takes to recharge or how much short recharges increase battery life), and Efficiency (how much the phone consumes in charging or discharging).

Over a year ago, DXOMARK set up a team of battery experts for the development of its battery evaluation system. The robots are set inside a Faraday cage, providing stable and controlled network conditions. The lighting setup in the cage is used to stimulate reaction of smartphone screens to light – a major factor for battery consumption.

“While battery performance is critical for consumers, they have negligible information pre-purchase to understand which device will best suit their needs. Specs like mAh and W do not indicate true battery performance. Battery performance depends on a combination of factors including the choice of hardware components and power management software optimization. Using our score centered on the end-user, we aim to guide consumers in their purchasing decisions,” said Olivier Simon, Battery Evaluation Director.
