Earth Day: Unplug Your Cell Phone

Posted by: Olga Kharif on April 16, 2008

According to cell-phone maker Nokia, if we were all to unplug our phones as soon as they are charged, we would do Earth some good. If only 10% of the world’s mobile phone users unplugged their chargers from the power supply once the battery is full, we could save enough energy to power 65,000 homes a year. Wow.

Now we just need cell-phone makers to come out with phones that let users know, by beeping or otherwise, that they are fully charged. Nokia, for one, recently launched its first mobile phone to include alerts that remind people to unplug the charger once the battery is full. I hope to see more cell-phone makers come out with this simple application in the coming months.

I can't bear to think about how much energy my laptop is consuming while I read this drivel.

Actually it would be nice if all primarily battery-operated devices had a "hey! I'm fully charged!" indicator, e.g., digital cameras. Next time I am in the market for a gadget that is going to be a point of consideration.

Totally agree. Think about the laptop battery fiasco. And ever had a cell phone battery go bad from over charging? I am convinced the cell phone companies count on this so they can sell us new chargers. Think about the fact that most digital camera battery chargers have an indicator that changes when the battery is fully charged. How difficult can this be to pull off for handset makers and the carriers that exploit their products (as well as screwing up their speed and functionality by swapping factory software for their inferior walled garden software). Hopefully the coming of Android and carriers' open software policies will help the situation, but I digress. The battery full indicator is a hardware problem -- if we are talking about a light on the charger --but it could potentially have a software fix in the form of a FULL icon and a beep or whatever -- and why can't they figure out how to make it shut the charging off even before you even unplug it? People should be able to plug their phone in before they go to sleep without worrying about killing their battery over night.
