O2 are launching a mobile phone charger that can reduce energy consumption by as much as 70% compared to those supplied by manufacturers. The charger achieves much of the saving by simply reducing the charge sent to the phone once its battery is fully charged.

The charger is undoubtedly a good idea, but at £14.99 I can’t see too many takers, the real question is, why don’t manufactures supply efficient phone chargers in the first place, O2 isn’t doing anything groundbreaking the technology has been used by manufactures of re-chargeable batteries for a long time.
