How much it costs to charge a smartphone for a year?

How much will the electricity required to charge a smartphone over the course of a year cost? underneath a dollar? many dollars? Tens of dollars? many dollars? Let's verify.

I'm on a mission, which mission is to avoid wasting on my power bill. I've already done the plain stuff, like replace lightbulbs - particularly the 500W halogens floodlights I even have outdoors - with low-power LEDs, and i am being additional careful on however i take advantage of heating and cooling. however along side creating huge changes, I've conjointly been viewing simply what quantity power all the random stuff I even have obstructed in uses.

Last week, I checked out what quantity power smartphone chargers consumed once there wasn't a smartphone connected to them. currently let's check up on what quantity power it takes to charge a smartphone for a year.

Now, the correct thanks to do that check would be to live the facility consumption over a year. Well, i would like results faster than that, therefore i might ought to do shorter periods of real-world testing and extrapolate out the results, that should not be a haul.

So, what I did instead of keep elaborated charging note for a year, or realize what quantity power it took simply to charge the battery from zero p.c to one hundred pc, and check out to fudge that into some real-world figure, I replicated what the majority do and place my smartphone on to charge nightlong and live the nightly power consumption.

I selected this technique for 2 reasons:

It's a usage pattern that matches what percentage individuals use their device

It is additional real-world, since once the device is on charge nightlong, not solely is power getting used to charge the battery, however conjointly to run the device (remember, your device is doing stuff within the background like checking email), therefore this goes on the far side simply activity the facility wont to charge the battery

Power consumption was measured employing a WattsUp? professional meter.

My check subject was the iPhone half-dozen and, that has the most important battery that Apple offers. i am conjointly a fairly serious user, and this meant that going all day was generally tough (the things I do for you). this implies that my results square measure planning to be at the high-end, which additional restrained smartphone users square measure planning to have a smaller power bill.

So here's what I found.

On average, throughout associate nightlong charge, the iPhone consumed a median of nineteen.2 Wh.

According to figures printed by the North American nation Energy data Administration for Gregorian calendar month 2016, the typical price per kWh within the North American nation was $0.12.

Remember that one kWh equals one,000 Wh.

So, take our average of nineteen.2 Wh per day, multiplying that by twelve months, we have a tendency to get seven kWh, that works out at $0.84 a year.

So if you guess underneath a dollar, well done.
