How much does it cost to charge your smartphone throughout the year?

Even with the rising cost of energy, we don’t think much about the cost of charging our smartphone throughout the year. However, given that we do this practically every day (depending on the model), it is still an intriguing question. If you have no idea how much these costs will cost, don’t worry because we will tell you now.

How much does it cost to charge your smartphone throughout the year?

Of all the electronic devices we have in the home—computers, televisions, smart speakers, including analog equipment like lights and heaters—it’s reasonable to think that nothing consumes such a tiny amount of energy as our smartphone. That is if we are using an iPhone, the file xiaomi smart phone or Samsung Galaxy or other equipment Android. But would it really be so?

The most accurate way to measure the cost of charging your smartphone is to make a small calculation that takes into account the energy lost in the charging process.

For example, let’s look at the iPhone 13 Pro battery as a reference point. The iPhone 13 Pro has a 3,095 mAh battery that operates at a voltage of 3.83V. However, you can look at the battery of your smartphone model and replace this value in the calculations. But back to the iPhone example.

First, we have to find out how many hours of energy the smartphone battery can store. To do this, we first need to convert milliampere-hours to watt-hours by multiplying the battery capacity by the voltage and dividing by 1000.

(mA * volts) / 1000 = Wh

Based on this equation, the iPhone battery capacity is 3095mAh / 3.83v 11.85Wh. We have converted from mAh to Wh because electricity consumption is measured and calculated in kilowatts.

Now let’s calculate the cost of charging an 11.85W battery, assuming it runs out completely. Let’s convert Wh to kWh, the unit the power company uses.

Wh / 1000 = kilowatt-hours

So, our iPhone battery capacity is 0.019 kWh. Now we have to see how much a kilowatt hour costs.

Now the calculation is as follows.

Battery capacity in kWh * Cost per kWh = Shipping cost.

Now if we charge the smartphone every day from zero to 100, we will see that charging the smartphone all year round costs less than 1 euro.

Yes it is not one euro per week nor per month. It’s even every year!

Of course, there are also devices that can measure this, the so-called wattmeters. However, the result will be quite similar.
