Here's an idea - how about the charger actually stops drawing power?

It *can't* be that hard to design a charger that doesn't draw power when it's not actually charging. Seriously.

This whole thing sounds fishy.

That would make too much sense... 🤣

The ac adapter/charger is a very simple device that has just one function: taking power from the grid & converting it to a form of electricity your battery can use. It's been about a decade since my last physics class, so I really couldn't explain (with any credibility) beyond that, but what we're talking about is a very simple device.

To integrate functions of power regulation into something like that would infinitely increase the complexity of the charger. It would actually be much easier to design a function like that into the device that's being charged, and in fact, that's been done with most consumer electronics. But even a function like that wouldn't be able to physically stop the connection from the grid to the de...

How about a charger with a switch on it. I cant believe Nokia can design Smartphones, but not design smart chargers. Why is that car charges have this ability to sense ignition and turn on. This will save zero energy its just to make people feel good.

A hard switch could work - that's a great idea!

Car chargers are different though - it's not that they sense when the car isn't on, but when the ignition of the car isn't on, or the engine isn't running, there's no power being supplied to the outlet.

No they do sense, at least the one i used to use. It would turn the unit off after 5mins. But the cigerette lighter still could be used even if the car was off. All they have to do is have the unit sense when something is drawing power, matter of fact my energezer battery charger does this, it turns itself off after the batteries are done charging. Its completely possible for them to add it into there designs. However it just a feel good thing, these reminders are not going to stop people who are 20mins late for work... etc.

It is possible. The car is running at a 12 volt circuit. It is relatively easy to ground out 12 volts. Your home, in most cases, runs with a 110 volt circuit. That is a little hard to ground out. So if you could figure out how to ground it out or stop it from completing the circuit. Maybe??? A switch??

While unplugging the charger may be the cheapest solution, it's certainly only the easiest and simplest solution for Nokia - not for the people actually using the charger. We're also talking about chargers that cost $1 to make and sold for $30.

No one, including myself, is going to unplug the wall charger to save such a small amount of little electricity. Most of the people I work with, sadly, don't even turn off their work computers when they go home at night because they're to lazy to wait for it to turn on in the morning. (Something I cannot understand.) And listen to how much people complain about having to plug in their phone *every night*. Do you think they're going to mess with plugging and unplugging the charger every night, to?

Another reason to totally ignore it.
