iPhone 5 costs $0.41 per year to charge

Energy efficiency organization Opower has calculated the annual energy cost for charging the iPhone 5.

The results showed that new iPhone users have to pay $0.41 a year to charge their devices, which equates to 3.5 kilowatt hours per year.

By contrast, the Samsung Galaxy S III costs a bit more at $0.53/year due to its larger battery.

But if taken in the aggregate, the power consumption for one year is significantly higher.

Opower writes:

“Even if we consider just the 170 million iPhone 5’s that are projected to be sold globally in the next year, their aggregate electricity requirements are nothing to sneeze at. The collective annual electricity consumption of the iPhone 5’s sold within 12 months will be equivalent to the annual electricity usage of 54,000 US households (roughly equivalent to the size of Cedar Rapids – the second largest city in Iowa). That’s just for one smartphone model over one year.”

The study also notes that giving up on more traditional entertainment sources in favor of smartphones would benefit energy consumption.
