This is the cost of charging your mobile phone per year, so you can calculate it.

Most of us charge our phones without thinking because they are an integral part of our connected lives. But how much do we spend a year to keep them fully charged? Very few have stopped to think about it.

Smartphones consume surprisingly little power, fortunately for us. Of all the electrical things you use at home (computers, TVs, smart speakers, light bulbs, etc.), we can assure you that nothing consumes as little power as your smartphone.

Although we will work out the real cost and how to calculate it later, since the price of energy is more expensive than ever, it is most likely that you will spend about one euro and a little a year on carry your smartphone.

Yes, no matter how many milliamps your smartphone has and charge it once a day, 365 days a year, most likely you will not exceed one euro on a mobile phone charge, regardless of whether it is iPhone or samsung galaxy. upload some airfields We don’t even tell you.

How to calculate the cost of charging a smartphone yourself

How can we say with such certainty that phone charging is so cheap? Well, in a very simple way, in which we’ll have to use math.

The most accurate way to measure the cost of charging your smartphone is use a physical instrument to measure actual power consumptionwhich takes into account the energy loss during the charging process.

But in practice this is a very small amount of energy, and small low voltage chargers are usually quite efficientso not much overhead.

With that in mind we feel safe using battery capacity as a benchmark for calculating how much power is used to charge it. You will need to find the capacity in milliamp hours (mAh) and the voltage of your phone’s battery.

For example, how to become a geek used the battery iPhone 13 Pro as the benchmark, Apple’s best-selling model of the previous generation and one of the best selling phones in history. The iPhone 13 Pro has a 3095 mAh battery running at 3.83 volts.

You can look up the battery capacity of your specific smartphone model and plug that into the calculations.

The first, we need to find out how many watt-hours of energy your phone’s battery can store. To do this, we first need to convert milliamp hours to watt hours by multiplying the battery capacity by the voltage and dividing by 1000: (mAh * V) / 1000 = Wh.

According to this equation The iPhone 13 Pro battery has a capacity of 3095mAh/3.83V and a capacity of 11.85Wh. It’s the same amount of stored energy, no matter how we label it, we’re just changing the units from mAh to Wh because electricity consumption is measured and billed per kilowatt.

Now let’s calculate how much it costs you to charge an 11.85 Wh battery., provided that it is completely exhausted. Let’s convert Wh to kWh, the unit your electric company uses for billing: Wh / 1000 = kWh

So the capacity The battery of our iPhone is 0.019kWh. In turn, you can calculate how much that amount of electricity costs you by checking your electricity bill for cost per kWh. We will use the current averagewhich is about 0.24 euros per kWh.

Our iPhone 13 Proin a perfectly efficient load scenarioloading from 0% to 100% costs 0.0046 euros. Assuming the battery was discharged every day of the year and then recharged: charging your phone during 2022 will cost you 1.6 euros..

But this scenario is unrealistic, since no one charges the phone 365 days a year from 0% to 100%, but usually the phone is charged at night when we have 20 to 40% battery, yes, the real number is much lower. It is about 1 to 1.20 real euros per year.

After doing all these calculations, you can see the charger of your iPhone or Android with different eyes, this is no longer the vampire that steals the euro, as you thought. And when it comes to charging some AirPods, you will surely laugh.
