Do Phone Chargers Use Power When Not Connected. Wirelessly however all the power is coming from the battery and the charger is only topping it upthe battery isnt getting a break. Other devices that run off DC internally.
Either way this shows us that the amount of vampire power consumed by your chargers is. If the adapter is warm even when the device is off its wasting a little electricity but usually not much. Once the phone is done charging the charger goes back to waiting for something to accept the power again so its similar to not having the phone plugged in at all.
Create a central charging area for all the devices in your house using a power strip with a timer even to ensure that nothing is left on longer than needed.
When my cell phone is charged fully it says Please remove charger from wall socket to save energy. Anecdotal evidence from 3 chargers of an Siemens Motorola and Samsung cell phone while charging at 4 3 and 3 Watt the measuring tool which is made for higher voltages and not very accurat for low values always reports 0 watt if no phone is. I am designing a phone charging station for my family. Further it may not charge all devices at their full current.
