Phones to alert users to save energy

HELSINKI (Reuters) - Your mobile phone could soon be prompting you to save energy by unplugging the phone's charger when the battery is full, an initiative Nokia (NOK1V.HE) said on Thursday it would roll out across its device range.

Mobile phones sounding a beep and displaying an alert -- "Battery is full, please unplug the charger" -- could save enough electricity to power 85,000 homes annually, Nokia said.

The phone maker has previously said it had agreed with other mobile industry companies on measures to reduce energy consumption and reduce pollution in the sector as part of a project in partnership with the European Commission.

Nokia said the unplug alerts are set to first appear on its 1200, 1208 and 1650 phone models.
