Nokia Shows Its Greener Side

Nokia has developed alerts for mobile phones to remind users to unplug the chargers from the wall once charging is complete. Users typically unplug mobile phones from the charger when done charging, but many leave the charger plugged into the wall. Even without a phone attached, the charger continues to draw current and wastes electricity. Starting with the mass market phones announced last week and eventually encompassing the entire range of Nokia phones, the alert will help save enough electricity to power 85,000 homes per year.

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 (w...

Another reason to totally ignore it.

I've got bigger things to worry about than unplugging my phone charger.

Like getting to work on time and remembering to put the toilet seat down.

All a/c adapters?

So do all A/C adapters draw electricity when plugged in? - even if the device they are attached to is off or they aren't attached to any device at all?

I have also heard that TVs use electricity when they are plugged in - they are in a standby state that allows them to be turned on by the remote control. If I remember correctly, some TVs in Europe allow you to turn the TV totally off so that it isn't using any electricity, but you also can't turn it on by the remote.
I'm pretty sure that's correct - czech out:

So how will it "let me know"?

So the phone alerts you when it's done charging? My problem: I charge at night, and don't want to be woken up at 3 am by my phone telling me it's full and the environment needs saving. I REALLY hope that this will be an option you can turn of...
The system will beep and display an LCD alert instructing you to unplug the charger. No word on whether you can change the wording on that alert, but we suspect it could be done. No word, either, on whether the monitor will beep incessantly until you ...

85,000 Homes

I would love to see the data that supports this assertion 🙄
i'm sure there's viable research out there that proves this - but nokia is probably the most popular manufacturer in the world. with the % of market share that they have, it is actually feasible.

plus, they could also be counting homes in africa...
That would be if everyone obeyed these messages, which they won't.
