DXOMARK has announced a new score for smartphone battery experience. The French hi-tech company is known for the tests and scores of camera, audio and display quality of consumer electronics.

“While battery performance is critical for consumers, they have negligible information pre-purchase to understand which device will best suit their needs,” said Battery Evaluation Director Olivier Simon.

“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,” he added.

Measuring battery performance from an end user-perspective
Strictly adhering to the company’s testing philosophy of scientifically evaluating the end user experience of devices, 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.

70 measurements, 6.5 days of testing behind each DXOMARK Battery score
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)
– Efficiency (how much the phone consumes in charging or discharging)

The test protocol contains lab measurements performed in indoor stationary settings complemented with tests in mobility.

Performed by experts using professional grade equipment
Over a year ago, DXOMARK setup a dedicated team of battery experts for the development of its battery evaluation system. To this effect, the company has invested in state-of-the-art equipment such as a set of touch robots that simulate human usage like gaming and browsing social media apps.

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.

First set of DXOMARK battery scores: 17 phones from all price segments tested
The Samsung Galaxy M51 emerges as the top ranked device for its overall performance. Lasting 80 hours in average usage the Wiko U30 is on the top of the autonomy rankings. 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.
