Nokia Adds Energy Saving Alerts To Mobiles

Nokia Adds Energy Saving Alerts
Could this little move save our planet?

Are you're one of those who plug mobile to charger, go to sleep and let it charge all night long and you don't care that it's wrong because it usually requires less than 2 hours or so to charge?

Well, to be honest I have never really thought that much about leaving my chargers plugged in after charging up and if nothing else I have to admit that's the waste of electricity somehow!

To address this, Nokia has launched the first mobile phones to include alerts encouraging people to unplug the charger once the battery is full and by Nokia calculations, this could save enough electricity to power 85,000 homes a year. Starting with the new Nokia 1200, Nokia 1208 and the Nokia 1650, the alerts will be rolled out across the Nokia product range.

Sounds good but instead of the annoying alerts I’ll rather see some smarter chargers capable to detect that battery is full and switches itself off whenever its necessary.

Anyway; Kirsi Sormunen; Vice-President of Environmental Affairs at Nokia said, "Around two-thirds of the energy used by a mobile phone is lost when it is unplugged after charging but the charger itself is left in a live socket. We want to reduce this waste and are working on reducing to an absolute minimum the amount of energy our chargers use. The new alerts also play an important role, encouraging people to help us in this goal by unplugging their chargers."

The alerts are one of a series of environmental initiatives that mobile manufacturers, led by Nokia, agreed to take action on this year. Nokia is the first of these manufacturers to implement the alerts into its products.

Nokia has decided to put the alerts into mass markets products first to help maximise the potential energy savings. The Nokia 1200, Nokia 1208, Nokia 1650 are targeting high volumes of sales in fast growing markets like India, China and Latin America.

The alerts are the latest in a series of energy saving initiatives from Nokia. Last year the company's newest range of chargers were awarded an Energy Star by the Environmental Protection Agency (EPA) in the US. for their energy efficiency. The chargers, in use since 2005, far exceed the EPA standards by using 50- 70% less energy than the Energy Star requirement, and also meet the highest European Union standards.

The company has set ambitious goals to further reduce the energy consumption of its chargers. By 2010 it aims to have reduced by an additional 50% the amount of electricity a charger consumes whilst still plugged into the mains but not the phone.

Great move actually.

However, it would be better if they could program the charger to turn itself off when the phone has reached full charge.

WTH? The phone/charger is suppose to cut off charging current to the batts as soon as the battery is full wert. Otherwise, all the batts would be dead within days of use.

Yeah, I thought so too. Otherwise the battery would be overcharged

The below is from my understanding of it:

AFAIK, the charger is meant to send power no matter what. That is, it has no circuitry or mechanism to cut off the power to the phone no matter how much the phone is charged. It is just basically a one-way charger.

As for phones, since the era of Li-Ion batteries, batteries can remain constantly charged no matter what. It is because Li-Ion batteries are designed to withstand such constant charges. Moreover, Li-Ion batteries 'love' being charged as much as possible, even when they're full.

Anyway, the issue here is not whether the phone's battery will be overcharged (for reasons explained earlier), but for energy-saving purposes, because as long as the charger is connected to a phone and constantly charging it, it is using up precious energy.
