We're making our phones more energy efficient. But did you know that if your charger is plugged in and connected to your phone it's still using energy, even if your battery is full?

We call this the no-load mode and typically two thirds of the energy that goes into a phone during its life is lost in this way. We've been investigating and implementing ways to reduce this and overall energy consumption of our devices.

• Our devices have a power-saving standby mode.
• Over the last decade we've reduced the amount of energy our best in class chargers use in no-load mode by 95 percent.
• In May 2007 we became the first mobile manufacturer to put alerts into phones encouraging people to unplug their chargers. We began with three new mass market phones and the alerts will be rolled out across the product range.
• The energy that could be saved globally by all Nokia phone users unplugging their chargers when their phones are full is equivalent to the amount needed to power 100,000 average-sized European homes. So pledge to unplug!
• Our newest chargers go beyond the US Environmental Protection Agency energy targets, using up to 90 percent less power in no-load mode than the Energy Star requirement, and also meet the highest European Union standards.
• We've introduced new Power Save mode with some of our latest devices, and plan to implement this to many of our new products to come. Power Save mode helps you to save energy and can be manually activated from the Power menu of the device.

You can monitor in real time how much power your device is consuming using Energy Profiler. Use it to see which applications on your phone use a lot of energy and turn off the ones you don't need.

We're also looking at the best way to use new sources of energy such as solar and fuel cells. In addition to company activities, Nokia is driving energy efficiency in cooperation with industry. Nokia is part of of the European Union's Code of Conduct focusing on energy consumption on no-load of mobile phone chargers. We were among the firsts mobile phone manufacturers to sign the Energy Star agreement with the US Environmental Protection Agency.
