Energy Efficiency

We work to improve the energy-saving features throughout our product portfolio, including energy-efficient chargers, to help our customers save energy. Small steps make a really big difference.

All our devices come with power saving standby settings, and our Lumia smartphones have a battery-saving feature.

We have also introduced applications, features and technologies such as ambient light detector, efficient Snapdragon™ processor, OLED or AMOLED displays, to save energy.

Choose a smarter mobile phone charger

To help you choose the most energy efficient charger, we along with other handset manufacturers use a common energy rating system.

We rate each charger according to how much energy it uses when it’s left plugged in to the mains (the so-called ‘no-load mode’). This makes it easy to choose the most efficient charger.

Five stars is the most efficient, while zero star chargers use the most energy in no-load mode (when they are left plugged in to the mains).

Power ratings for our mobile phone chargers

Check out the ratings for all our chargers.

Our most energy efficient chargers earn a five star rating. The label looks like this:

Continuous improvement through smarter design

An important part of our business strategy includes reducing the energy consumed by consoles within a generation while maintaining the same level of gaming power. For example, since launch of Xbox 360 in 2005, the engineering teams have successfully reduced standby power by a factor of 10, to less than three tenths of a watt, resulting in a 60 percent reduction in energy use. Our development and compliance engineers ensure that all of our products meet regulatory requirements, such as the EU’s Energy-Related Product Directive.

Carrying lessons learned from Xbox 360 forward to Xbox One We continued the commitment to reduce energy usage through the design of Xbox One, launched in 2013. Xbox One provides eight to ten times the processing power of Xbox 360. Despite this significant increase, the electrical power required for gaming is 30 percent less than that of its predecessor when it launched in 2005. Power needed for media play and dashboard is half that of the Xbox 360 at launch. The increase in efficiency results from scalable processor architecture that wasn’t available for Xbox 360. Other efficiencies are gained by providing the user with choices about console functionality while in standby mode.

In 2009, game consoles were identified by the European Commission as a “priority product group” to be covered either by regulation or a self-regulatory initiative for the purpose of reducing greenhouse gas emissions. We have been working with other console manufacturers to develop responsible requirements to achieve that goal. The resulting initiative is in the form of a design specification for Xbox 360 and Xbox One. In other words, our current products comply fully with the requirements in the initiative. This voluntary agreement is a joint commitment by the manufacturers, which is estimated to deliver collective energy savings in the EU of 1 TWh per year by 2020. This corresponds to the annual electricity consumption for over 250,000 households. On April 22, 2015, the European Commission confirmed that the voluntary agreement would achieve the policy objectives set out by the EU's Ecodesign Directive more quickly and cost-effectively than mandatory requirements.
