Energy efficiency - Efficient use
Unplug the charger
During the use of a mobile phone or tablet the product’s environmental impact mainly comes from energy use. If electrical products are switched off but left plugged into the wall socket, they still consume electricity – called standby consumption. All chargers and power converters connected to the grid are draining small amounts of power, and the drain from many sources leads to a substantial amount of energy wasted. The charger should therefore be unplugged from the wall socket once the product is fully charged to avoid energy being wasted.
Energy consumption beyond the product
As we have gone from relatively simple mobile phones to complex smartphones and tablets, the energy consumption pattern of our devices has changed. No longer can we simply say that they only consume energy while charging. Smartphones and tablets are multifunctional tools that can be used for everything from emailing to video chatting. All these activities consume energy, not only in the device itself which results in more frequent charging but also in the network that supplies these services and in the servers that store all the data. How much energy consumption a device causes depends on how the device is being used. One of the most energy consuming activities in the network is the downloading, uploading and streaming of video.
Configuration of your mobile phone
To increase the time between charging and to help save energy, you can easily adjust the settings of your mobile phone. This will enable you to use your phone for a longer period before the battery needs to be charged as well as minimise the energy consumption (and related carbon dioxide emissions).
