While I'm sure it's not 0W, even if it was 0.5W, do you know how much it costs you to keep it plugged in 24/7 for a whole year?
In USA the math is very simple.
As a rule of the thumb, you look at the wattage the device uses.
Take that number, and that's the amount of dollars you pay, leaving it plugged in 24/7 for a whole year.
In other words, if you have a 60W lightbulb, and keep it burning for a whole year, 24/7, never turn it off,
it'll cost you roundabout $60 that year on electricity.
That being said,
If the charger with phone on fully charged, or even without phone, was plugged in 24/7, it will cost you less than $0,5 per year on electricity.
Not worth the cost of unplugging and risking battery loss over here...

Hey thanks for that tip. Especially since electricity we pay for is done in kilowatts not watts.
Oh wait at 15 cents a kilowatt or 1000 watts can you double check your math.
Oh and except for the hall light none of my lights are over 23watts.
Well now I have met some people that would tell you to spend $1000 because you need to save energy in the amount of less than 1 kilowatt a year.
Heck it cost more energy than that to build the refrigerator.
I told that person if they thought I needed a new refrigerator that bad, they could buy it for me.
So Yea sometimes the savings is not worth it.
Rather like unplugging your cable box to save pennies. If it goes out because you are constantly powering it down, you will owe cable at least $200.
