How much does it cost to charge your iPhone for a year?

“If you’re anything like me, you have a number of gadgets within arms reach that are either on charge right now, or will need charging at some point during the day,” Adrian Kingsley-Hughes reports for ZDNet.

“Maybe it’s a smartphone or tablet, or a laptop, or a wearable. They all have one thing in common – they need power,” Kingsley-Hughes reports. “And that power costs you money. But how much money?”

“As regular readers will know, I’m a big fan of real-world testing. The only drawback of real-world testing is that my “real world” is going to be different to your “real world,” which means that your mileage can, and probably will, vary. But, as long as a few variables are nailed down, these differences shouldn’t be too great,” Kingsley-Hughes reports. “Here’s what I found. On average, during an overnight charge, the iPhone consumed an average of 19.2 Wh. A miniscule amount, but over a year that translates into 7 kWh, which will set you back $0.84.”

MacDailyNews Take: We don’t know how we’re going to swing the annual cost of charging our Kindle Paperwhites – they cost slightly over 1-cent per year to power!


  1. This, apparently, is what happens when a blogger has too much time on their hands – they start thinking about pointless things to keep from eating too many Bon Bons.

    1. This might seem like a silly inquiry, but just this week there was some commenter on MDN claiming that an iPad uses more electricity than six refrigerators. I guess he was wrong!

  2. Costs me nothing. My solar power system produces 2,000 to 3,000 kWh more each year than I can use. Not enough to warrant buying an electric car, though, sigh….
