Study finds the iPhone 5 costs $0.41 a year to charge

Okay, so you have your new iPhone 5. Although Apple claims its new handset’s battery can last around 8 hours, there will come a time when you have to recharge.

The new iPhone will cost you more to charge, but by only pennies, a new study finds. Keeping your four-inch iPhone 5 fully charged will cost you $0.41 cents per year, or $0.03 more than the iPhone 4

Yes, you can’t buy anything with $0.41 cents nowadays, but the energy-efficient obsessive folks at Opower want you to look at the big picture.

If we combine the electricity required to charge the 170 million iPhones 5 units experts believe Apple will sell over the next twelve months, it’s equivalent to the yearly electricity consumed by 54,000 US homes.

For just one iPhone model over only one year.

But how does the iPhone’s energy consumption rank with other electronic devices?

Your iPad uses $1.36 of energy annually, but it is pretty miserly compared to other common living-room electronics. A laptop PC burns up $8.31 per year, while a desktop PC costs $28.21 per year, according to the study.

It may be wise to use your iPad or iPhone to view movies and television, given that a set-top box eats $30.20 in electricity. While that Xbox 360 may provide some fun moments it is also costing you: $40.24 per year.

But the prize for electricity hog goes to the 42-inch plasma TV: $41.13 annually.

That works out to 100 years for a single iPhone 5.

On a somewhat related note, we got mixed results in our recent poll asking about your battery life on iOS 6 devices. Nearly 30 percent of respondents thought their battery life improved with iOS 6, with approximately the same percentage of respondents voting for “Worse”.
