Energy consumption during mobile phone use
Using a mobile phone accounts for around a third of the total energy consumption throughout its lifecycle (see environmental impacts of mobile phones).
The most significant contributor to this energy use is phone chargers that are left plugged in but not connected to a phone. Chargers are becoming significantly more efficient, but this is likely to remain an important part of energy use for some time. Broadband routers and internet television boxes also use energy, while in operation and on standby.
We reviewed our policies on working with suppliers in 2007/08 to prioritise CR issues. We are working with suppliers to investigate green technology options, including developing a universal charger (so customers do not require a new charger each time they update phone), a low cost solar charger for use in emerging markets and a "green" phone.
