How much does it cost to charge a mobile phone?

Answer

The cost for charging a mobile phone differs based on the model. For example, as of September 2012, the iPhone 5 cost 41 cents worth of electricity per year, while the Samsung Galaxy S cost 53 cents per year.

Some environmentalists consider these figures great news. As people become more dependent on mobile phones, they save energy by not having to use other devices around them. However, another factor to consider is the number of mobile phone users all over the world. It is estimated that by 2016, a total of 1 billion smartphones will be used by people worldwide. Also to be taken into account is the energy consumption needed to meet the Internet demands of these mobile phone users.
