Have you ever wondered how much does it cost to charge your smartphone? Below we will see how much energy is needed to charge a smartphone a whole year.
The right way to do it is of course to measure the energy consumed by one device for one year. But because no one is going to enter such a one procedure we will do the test with smaller measurements and use math.
So we will measure the energy needed to charge a battery from 0 percent to 100 percent, as most do. We will charge the smartphone during the night.
This method is the way most people use to charge their device.
Energy consumption can be measured with various products such as the WattsUp PRO meter.
Η essay it happened to me on an iPhone 6 Plus, which has the largest battery currently offered by Apple.
Let's see the numbers:
On average, during an overnight charge, iPhone consumed 19,2 Wh.
According to data published by PPC (family PDF invoices) the average cost per kWh in Greece is 0,107 of the euro.
One (1) kWh is equal to 1.000 Wh.
So with 19,2 Wh the day, multiplying by 365 days, we have 7 kWh, which cost 0,749 the euro over time.
Of course the result will change according to the decisions of the troika - government. No one can guarantee who it will be price of electricity for a whole year, just as no one can tell how much VAT will be next month….
