Your iPhone uses more energy than a refrigerator - The Week

How much energy does it take to power your smartphone addiction?

The average iPhone uses more energy than a midsize refrigerator, says a new paper by Mark Mills, CEO of Digital Power Group, a tech investment advisory. A midsize refrigerator that qualifies for the Environmental Protection Agency's Energy Star rating uses about 322 kW-h a year, while your iPhone uses about 361 kW-h if you stack up wireless connections, data usage, and battery charging.


This seems a little weird. I wonder if this is true..?.

I use an old iPhone 4 on wifi only for checking email etc when my desk top PC is off.
It takes so long to boot up, I leave it on and charge it once a week.
Maybe I should leave it off and just reboot when I need it..

For Cells, my wife and I use cheap TracFones, which we leave off,
(full power-down) about 80% of the time.
I charge mine once a week, if needed.

Pretty ridiculous title thats only meant to be eye catching. Server farms have been growing for ages as our techyness demands more and more. Its not like throwing away your iphone is going to save the world 361 kWh a year.

For kicks I ran the numbers on charging. My smart phone has a 1650 mAh battery at 3.8V. That means it holds 6.27 Wh of power. That is 0.00627 kilowatt hours. Say I have to recharge the whole thing every day (its less than that) and it comes to 2.29 kWh a year. More than I would have thought, but really thats nothing.

Even running my Netbook at 25 watts 24/7 is .6kwh a day is 219kwh per year.
My laptop is 40 watts or 360kwh/year. Which actually is about the same as my non-energy star refrigerator after I modded it for additional efficiency.

Bull****.

Corporate propaganda. How about a S3 or 4?

Fact, ipad 3, charger rated at 15W, charging from 5-8 % to 100% up to 6 hours. A very brief math, if charged daily, 6x15=90W, 90x365=32.850W per year meaning a wooping 32,85KWh.

An iphone charger is rated at 5W. Any questions?

Later Edit. ... and charging time arownd 3 hours.

I cannot recreate the math used to come to the original author's conclusion:

Kill-A-Watt + iPhone charger =0W standby
Kill-A-Watt + iPhone charger + iPhone 4S = 6W

Assuming you charged your iPhone every night for 8 hours, you would consume 17.52kWh for the year. (6W*8h*365)/1000=17.52kWh

Whenever my wife charges up her iPad mini or when I charge up the iPhone4,
I'm always amazed at how fast these things charge up. Seems like they get most
of their re-charge during the first hour.

I hope these batteries don't wear out too fast, being re-charged so often.

@where2 If you leave your phone conected 8 hours to charging it won't take 6 W all the time, only first 2 hours and the rest of the time the amount of power is only for sustained charging, about 1 W to 2-3 hours.

Just goes to show how efficient modern refrigerators really are.

Yeah, ours is getting long in the tooth..
We are thinking about one of those with the freezer down on the bottom.
I'll have to start reading the reviews..

If you're looking for a unit that only uses 300 kwh per year, expect to pay big bucks for a smallish unit. AC_Hacker did a freezerator hack on a small deep freeze, and his usage was around 400 watt-hours per day.

There are only a few retail units that boast the same performance. A euro-market bosch kge39ai40 uses around 390 wh per day and costs around $2000. Most USA-market units use upwards of 750.
