Owners of Apple’s new iPhone 5 and Samsung’s Galaxy S III don’t mind singing the praises of their smartphones or talking down their rival’s.
Researchers at Outlier, however, say both sides have something big in common: The annual cost of keeping their phones charged is minuscule.
It’ll cost about 41 cents to charge the iPhone 5 and 53 cents to charge the Galaxy S III, Outlier said. The cost for juicing the Galaxy is larger because it has a larger battery.
Outlier measured how much electricity it took to charge each phone from 0 percent to 100 percent full. The iPhone 5 used 3.5 kilowatt hours of energy while the Galaxy S III used 4.9 kWh.
Outlier paints a much different picture about power consumption, however, when you consider the “power of multiplication.”
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.
Just think, as Outlier points out, global smartphone shipments, including upgrades to newer phones, will reach 567 million devices just this year and by 2016, 1 billion people worldwide will own smartphones.
That’s a lot of juice.
