We are continuously improving the energy-saving features throughout our product portfolio, including energy-efficient chargers, to help our customers save energy. Additionally, already in 2007, Nokia was the first mobile manufacturer to put alerts into mobile phones to remind people to unplug their chargers once their phones were fully charged. With over a billion people using Nokia phones around the world, small steps like these make a really big difference.
All our devices come with power saving standby settings, and our Lumia smartphones have a battery-saving feature. Browsing the internet and making video calls is more energy-efficient with a mobile device, compared to a laptop or desktop computer.
Check out some simple tips to reduce the energy your handset uses.
We have also introduced applications, features and technologies such as ambient light detector, efficient Snapdragon™ processor, OLED or AMOLED displays, to save energy. Please visit Nokia Store Green Channel to find a whole collection of green apps.
Choose a smarter charger
To help you choose the most energy efficient charger, we’ve joined forces with handset manufacturers to create 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’re plugged in and fully charged).
Power ratings for our chargers
Check out the ratings for all Nokia chargers.
Nokia’s most energy efficient chargers earn a five star rating. The label looks like this:
Between 2000 and 2009, we reduced the average no-load power consumption of our chargers by over 80%, and best-in-class chargers by over 95%. With the recent introduction of more 5 and 4 star chargers, the current figures are even more impressive.
New power generation
We research and experiment with the best way to use new energy sources, in particular, solar power. Ever wondered whether it’s possible to power a mobile phone just from the sun’s rays? As part of our long-term research into energy efficiency, we are testing solar charging in Nigeria and Kenya currently. The Portable Solar Charger is part of a project where Nokia is exploring the charging opportunities for people that do not have access to the electricity grid. Kenya and Nigeria provide the perfect opportunity for testing this solution as recent World Bank reports indicate that only 16 and 51 per cent of Kenyans and Nigerians respectively had regular access to electricity between 2007 and 2011.
Thousands of people in Nigeria and Kenya are set to pilot the Solar Charger. The pilot will be studied to see the product’s business potential, usage patterns, the environmental and social impacts, and whether it could be introduced for full commercial production.
