🔋 How Much Does It Cost to Charge Your Phone Once?
Tech Tips:
Typically, a mobile phone charger consumes between 5 to 20 watts of power. A standard charger uses around 5 watts, while fast chargers can go up to 18–20 watts or more. Charging a phone fully usually takes about 1 to 2 hours, depending on the phone model and the charger used.
Many people often wonder — does charging your smartphone every day increase the electricity bill?
The answer is no — charging a phone consumes a very small amount of electricity. But how much exactly does it cost to charge your phone daily? Let’s break it down.
⚙️ Power Consumption for One Full Charge:
Let’s say you're using a 10-watt charger and it takes 2 hours to fully charge your phone.
Electricity consumption = 10 watts × 2 hours = 20 watt-hours = 0.02 kilowatt-hours (kWh) = 0.02 units of electricity.
So, each full charge of your phone consumes just 0.02 units.
📅 Yearly Electricity Cost of Charging Your Phone:
If you charge your phone once per day, the annual electricity consumption would be:
0.02 units × 365 days = about 7 to 10 units per year (depending on exact usage and efficiency).
Now, if your local electricity rate is ₹10 per unit, then:
Annual cost = 10 units × ₹10 = ₹100 per year.
(Note: The actual cost will vary depending on the per-unit electricity rate in your state or region.)
⚠️ Tips to Save Electricity:
-
Even when your phone is fully charged, if the charger remains plugged in, it still draws some power.
-
To avoid unnecessary electricity usage, unplug the charger after use.
-
Consider replacing old chargers with newer, more energy-efficient models.
💡 Bottom Line:
Charging your smartphone costs very little — just pennies per day or about ₹100 per year on average. Still, mindful habits can help you save more and prolong the life of both your device and your electricity bill!
