Using a Watts Up Pro Electricity Consumption Meter, we measured how much electricity it took to charge each phone from 0% to 100% full. Taking those results and modeling them across a year (see Methodology), we found that on an individual basis, the latest smartphones use a trivial amount of electricity. The typical smartphone owner spends more than 2 hours per day using their phone, and they spend two-thirds of that time browsing the internet, social networking, playing games, listening to music, or watching shows and movies.
