Comments on: Your cell phone is charged--please unplug

A Nokia-led European Commission task force offers ideas for making mobile phones greener.

Block the Charge

Wouldn't it make more sense to stop the charging automatically instead of alerting the owner? Surely an onboard switch could be added to keep the phone from continuing to charge until it needs it. Not that hard.

Block the Charge

I agree. The last thing I want is to get up at 2AM to remove my cell phone from the charger. My current cell lights up and there is a message on the display when the charge is complete, but if I'm asleep I don't see it.

Fix your phones

Redesign the power management and charger. Jeese... What a surprise Nokia finds this to be the user's fault.

[mkhecker]

What they don't mention is...

I saw a very similar news story a year ago, except it wasn't by a major cell phone manufacturer. What Nokia doesn't say is that charger technology has improved to where they can be made to not leak electricity, or at least a small fraction of what they do now. But of course instead of spending more on better chargers, they just are going to annoy their customers. Which do you think would have the greater impact in the long run?

Nokias have turned into such ugly things anyway.

Why you should unplug things.

From what I have heard, devices (such as cell phone chargers, TVs, or anything else electronic) continue to use electricity even when they're not in use. So, the point of the request is not to wake up at 3am, but rather to only have your cell phone charger plugged in while being used.

Power Saving

I think that's rich coming from anyone because just about any company that makes such proposals, wastes far far more in powerful light displays & in many other ways themselves. Maybe Vegas lights should be shut down & nobody use a private car or take a plane ride. Get real. I'm every bit in favor of saving power consumption but lets start with the really big users as they consume considerably more than Cell (or Mobile) phone users might do with their battery charges.

[nuckelhedd]

The solution is simple.

Require makers of cellphones and their companion chargers to sense when the charge is complete and turn the charger off automatically. Problem solved with a micro circuit. Christ corporations and their overlords are morons. I suppose next they'll want us to stop using forks since we could save more energy by only having to produce spoons.

[Dr. B]

Mind telling me how that works?

"The members of the task force, a project of the European
Commission (EC), agreed to include alerts on the cell phones
they make that will remind people to unplug their charger once
a phone is fully charged. If 10 percent of the world's cell phone
owners did this, the group's final report said, it would reduce
energy consumption by an amount equivalent to that used by
60,000 European homes per year."

Ok, so now that you've told me how much energy we can save,
mind telling me how this works? I wasn't under the impression
that chargers use any energy other than when they're charging
phones. Do they suck electricity out of the wall and spit it into
nowhere the rest of the time or what?

They are little heaters

Low-quality chargers are always on. The energy is wasted as heat. Therefore, in the winter, this heat is actually NOT totally wasted. Same with lights being left on, or any inefficiency. If it's real cold outside, it doesn't matter much. In the summer, though, it's a double waste. Not only do you not want the waste heat, but you have to run the A/C more to compensate.

So I'm going to get up in the middle of the night...

Um.. you force us to use those rediculously large plugs on the phone, why not use those connections for something? You want to save energy? The phone knows when its charged. How much would it cost to add circuitry to tell the charger to shut off??? Pennies, I'm sure.

Unplug THIS!

I am constantly amazed at what passes for news and product improvement. Why in heavens name wasn't that basic design built into the charger?
If I were Nokia, I would be embarrassed to even mention this "improvement". They (Gov)should slap them (cell phone makers, not just Nokia) with a fine for such a stupid and penny pinching oversight.

I have 3 batteries that my cellphone provider tells me have been overcharged, causing the battery to last a shorter time between charge AND voids the 1 year warranty . Who the heck put their phone in a cradle then set an alarm for 3 hours to go take it out when it's "charged".

Morons, the whole lot of them!

Charging phones

I think it would work if you turn your phone off at night and then when it gets fully charged the charging will stop. If you leave your phone on it keeps using some of your battery and therefore needs to keeps charging. At least that is how my phone works. I just charge it in my car on the way to/from work each day and never charge it by AC unless I am on vacation or something.

[disco-legend-zeke]

Smarter charger more likely than smarter consumers.

Eating two less slices of toast for one day would save as much electricity as a year or two of trickle charging.

That said, smarter chargers would stop current when battery capacity is reached

[mahurshi]

well said.

i agree.

[menty666]

So long as I can turn it off...

I charge my phone over night while I sleep. If it woke me up to tell me it was full I think I'd put it through a window.
I like the ideas to block the charge myself but it's not really the problem. Any device that's plugged in is taking in electricity whether it's used or not. There are hundred of articles out there about so called "energy vampires" doing this and adding to household electricity bills. The solution isn't to stop the charge or wake me up, but rather the consumer actually has to physically unplug that god awful brick from the wall.

[eeee]

include a switch on the charger

Simply include an on off switch in the charger housing to enable saving power without having to unplug it

[eeemang]

store doors stay open with AC wasted

Bigger waste is found:
-stores that leave their front doors open in the summer to invite customers while the air conditiong cranks and flies out the door
-parking lot lamps that burn all day long: (ie CompUSA-White Plains,NY;
-highway lamps on all day: (ie Cross County Pkway; Major Deegan Expy, Bronx River Pkwy in NY)
-office buildings that run lights 24 /7 but are open only 9 hours for business (250 North St-White Plains)
-large corporations that leave meeting room lights on with no meetings
-office buildings so over cooled in the summer that people plug in electric heaters
You all have many more examples of waste that is zillions of times more than our 10 watt cell phone chargers.
