Get your calculator ready if you don't believe us.
We’re all guilty of having our mobiles in our hand constantly. Whether we’re texting, calling, streaming or browsing our socials.
By now, you’ve no doubt clocked up a fair few hours plugged into the mains. The common routine is to use your mobile all day long then charge it through the night.
Bills don’t pay themselves and with all this charging, we imagine your minds have started wandering thinking about how much electric you’re using.
If you’re anything like us, you probably have a silly number in your head like £600, but we assure you it’s a lot less than this and we did the maths to prove it.
After pulling together a few figures, concentrating really hard, we worked out how much it would cost to charge your, let’s say, iPhone 13, per year.
Drum roll please… The total cost is just £2.48 a year – that’s less than one single Tesco Meal Deal.
How’d we get there?
£2.48 suddenly makes us feel a whole lot better about charging our iPhone all night long but you’re probably wondering how on earth we got there.
So, we’ll start with the cost of a kilowatt hour (kWh), which is an average of about 17.2p in the UK.
Take a look at the iPhone 13. If you use a 20W (0.02 kilowatts) charger that will juice the battery up from empty to full, in about 2 hours’ time – hella impressive in itself!
What we do then is multiply the 2 hour power time with the 20W charger, giving you a total of 40W.
This number is the total amount of electricity that your iPhone 13 barely sips from the grid every time you replenish from 0% to 100%. Given that a kilowatt costs 17.2p, 40W will set you back a cool 0.68p. Not even a full penny.
The next bit was super-easy. 365 days in a year, so 0.68 multiplied by 365 gives a nice round total of £2.48.
You can apply this genius mathematic solution to most devices on the mobile market. Take the latest Galaxy S22 for example.
A 15W charger will get you powered up from 0% to 100% in 2 hours. Applying the same maths as above, the total to cost your Galaxy S22 per year is £1.86 – slightly less than he iPhone 13.
Whether you’re Apple or Samsung loyal, the cost per year to charge your mobile is super-low – less than your average pint of beer or a Big Mac meal at McDonalds.
The cheapest juice around.
This article should’ve made you feel a whole lot better about plugging your mobile in all night.
