How Much Energy Does Your Smartphone Use?

By September 29, 2016March 14th, 2019No Comments

In today’s digital world, we use our various devices for just about everything. There are few of us for whom a day goes by without our cell phone power consumption almost completely depleting our device. It seems like we’re always looking for a place to plug in and recharge. But did you ever wonder how much energy your smartphone uses? We have the answer, based on cell phone usage statistics, and it might surprise you.

iPhone Power Usages vs. Other Cell Phone Power Consumption

The world is divided into people who primarily use Apple products, and people who don’t. Mac vs. PC. iPhone vs. Android or Windows. Many people who are iPhone devotees feel that their devices are far superior. How true does this hold when it comes to iPhone power consumption?

Sorry, iPhone fans, but the truth is all smartphones use up about the same amount of energy. However, the good news is that amount is actually negligible — about 1 kilowatt hour per year. That’s equivalent to the amount of power it takes to light a 100-watt light bulb for about five minutes. One kilowatt hour costs about 12 cents worth of electricity. So, put in context with the rest of the digital economy, your tablet uses about ten times that much, which still amounts to only around a dollar of energy per year. As far as your laptop is concerned, it might use closer to 100 times that much, but it’s still less than $10 a year of energy use.

Now, with respect to cell phone charger wattage, your cell phone charger uses about 20 kilowatt hours of energy, but only if it’s plugged in. If you kept it plugged in around the clock, 24/7, it would use about 175 kilowatt hours over the course of a year, which would still be only about 20 dollars’ worth of energy — but of course, you don’t need to keep your charger plugged in all the time.

Cell Phone Power Consumption vs. Refrigerators

Have you heard about how your cell phone uses enough energy to power two refrigerators? Don’t sweat it. The truth is it’s mostly nonsense. This news bite is derived from cell phone usage statistics about how much energy it takes to send data to and draw data from the cloud. Your specific cell phone isn’t responsible for all that energy, though. It’s spread out over the millions and millions of cell phones that use data every day, and it shouldn’t fit into your personal calculations.

So feel free to use your smartphone without worrying about your carbon footprint. Just make sure to turn the lights off when you leave the room.
