iPhone 5 Costs Roughly $0.41 Per Year to Charge




Energy efficiency company Opower today released a study calculating the annual energy cost for charging the iPhone 5 at just $0.41. While any user's actual cost would vary based on use and electricity rates in their areas, Opower's estimate assumes a full charge once per day at a U.S. average of 11.8 cents per kWh.

But while an individual iPhone 5 uses a minuscule amount of energy, the massive popularity of Apple's devices results in significant energy demand in aggregate.
Quote:
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.
Still, the study notes that smartphones use significantly less energy than other entertainment devices, and a shift from more traditional entertainment sources to smartphones can result in an overall benefit to energy consumption.




The explosion in smartphone usage is of course just one part of a surge in consumer electronics, which now represent approximately 13% of U.S. household energy usage. That growth, which comes even as the efficiency of appliances and other devices has significantly improved, has been driven by a massive increase in the kinds and numbers of devices being used in homes, from televisions to gaming systems to computers.

iPhone 4 is cheaper, might as well buy that instead.

Like people are really concerned how much there cell phone costs to charge.

They are so much more concerned that it doesn't have NFC that they can't really use anywhere.

I know for sure that doing my casual surfing with iPhone/iPad instead of the MacBookPro did wonders for my energy bill.
According to this, I should use the iPhone instead of the iPad more often to save even more energy.

Interesting. If I were to have taken a wild guess before I saw this article I would have guessed around 10 bucks.

Useless info

Probably the most useless and irrelavent article I've read in a while. My drive to work (12 miles) in one day uses more "energy" than my iphone will ever use. Is this trying to make me feel bad that we have iphones?

It takes more to write an article on this than it does to charge the iPhone. Silly article.

If we translate that over to Australian energy prices I believe the iPhone 5 costs $685.76 AUD to charge per year.

Why would you think that?

I think statistics and knowledge are very cool and always interesting. Why would they make you feel bad?

No. I just thought it was an interesting comparison that most people never think about. As we've seen already in this thread, people are surprised how small the number is.

And of course larger devices use more electricity than smaller ones. But would I have guessed that an Xbox 360 used 100x more energy if I had ever really thought about it? Probably not.

Take it for what it is...a quick look at how little energy a smartphone uses and how that compares to some other stuff you have around the house. It's not good or bad unless you want to make it so.

We should buy phones without screens, because really, phones are where we waste most energy. Right?

Extremely ... extremely minuscule. Hook it up to a Kill-A-Watt sometime. Basically, the electrical cost of a cellphone or a Macbook Air for an entire year is less than 1 visit to Starbucks. Now, x millions of cellphone users adds up but still... My 800 watt gaming computer makes me a terrible person. <cough>

Check out: http://standby.lbl.gov/summary-table.html

Looks like .26 watts? lawl

They do mention the Galaxy S3, which I must point out costs more money than the iPhone 5. Take that Samsung!

This is indeed little, but what about all the servers you access and the antennas it uses to connect you to calls and the internet?
