How much does it cost to charge a smartphone cell phone for 1 year, 1 month, 1 week, 1 day or 1 hour?


We are going to calculate this out based on average low and average high numbers. Your exact amount may vary depending on your electricity cost where you are located and also which phone you are using. 

The quick answer to how much it cost to charge your cellphone per year is 

20 Wh per day x 365 days = 7.3 kWh per year

Low range = $0.12 x 7.3 kWh = $0.88 per year

($0.002 per day or $0.06 per month)


High range = $0.20 x 7.3 kWh = $1.46 per year

($0.004 per day or $0.12 per month)

Your outcomes may vary based on what phone you use, where you are located and how many times you charge your phone per say.

Conclusion:

Keep charging your phone, it should only cost you about one dollar per year.


Assumptions made:

Average phone charge 1 time per day, 20 Wh per say per phone
