iPhone 5 vs Samsung Galaxy S3 Energy Impact Analysis

Under: Mobile Phones
By:Mark | September 28th, 2012

Opower, the energy information software company, has done an analysis of what it costs iPhone 5 users to charge their phones every day for one year. It turns out that it costs about $0.41 a year, or 3.5 kWh. In comparison, Samsung Galaxy S3 users will pay $0.53 per year (4.9 kWh), due to the Galaxy’s larger battery.

The cost seems negligible, but from an environmental perspective, the energy consumption of popular smartphones has an enormous impact: the 170 million iPhone 5s that analysts believe Apple will sell in the next 12 months will draw enough electricity to power all of the homes in Cedar Rapids, Iowa for one year.

And the energy requirements of operating smartphones go far beyond charging the battery. In particular, smartphones are driving a huge boom in Internet traffic: in 2011, monthly internet traffic stemming from the average smartphone tripled relative to 2010 levels (150 megabytes compared to 55 megabytes), and the current level is projected to grow 17-fold by 2016. Processing all of this data traffic potentially carries a heavy energy price tag of its own, in the form of data centers.

When all’s said and done, smartphones prevail as an energy-efficiency winner compared to traditional notebooks or desktops – when sending an email, watching a video, or sharing a family photo. Put simply, a day spent web-surfing and Facebooking on a smartphone or tablet is a much more energy-efficient day than doing the same on a traditional computer.

    it doesn’t take in consideration that the S3 battery life is greater than on the iphone 5…so you put it on charge less during a year.

    All this analysis shows is that the Samsung’s battery is larger. Of course it’ll take more to charge. What needs to be measured is how much each phone drains during a benchmark suite of apps. That .53 cents per year is pretty small compared to the $100/most service charges.

    Don’t use your microwave once this year it will more than cover this?

    Ridicules comparison.

    Do you just write articles to write articles?

    Is it me? But doesn’t the charge last a lot longer on the s3. And since we are talking talking phones and not batteries. I smell fanboism. The s3 can also reduce energy flow with the very cool nfc ;)
