It’s been a busy old week round these parts, but I couldn’t miss out this week’s installment of Save Energy With One Simple Step as it’s a particularly pertinent one for me.  Back at the beginning of this blog, I wrote about my un-green habits, and one of them being charging my mobile phone overnight.  I’m shamefully still quite bad at doing this so I thought I’d write this as a reminder to myself and anyone else who has fallen into the same habit.

So, without further ado:

charging phone night bad

Unplug your phone (at night).  And get into the habit of charging your phone by day.

It only takes less than 2 hours to charge my phone, but leaving it plugged in charging overnight for 8 hours is using 6 hours of extra power that doesn’t need to be used, wasting energy and money.   And if that wasn’t bad enough, as a consequence of doing this, I’ve damaged my phone’s battery, so even though it’s only a year and a half old, it doesn’t hold a charge for very long, which means soon I will have to replace the battery or the phone.  So I’ve considered this a very good lesson learnt.

I’ve recently started taking a USB cable with me to work and charging my phone by day by plugging it into my computer, and when I’m at home, charging it via the USB cable when I’m working on my laptop.    I haven’t been able to find any reliable form of research or analysis on charging your phone via a computer versus plugged into the wall, so I don’t know how much extra energy, if any, a computer uses when it charges a phone.  Hwwever, I’m guessing it’s a lot less than leaving a phone charging overnight. And I know that pretty much as soon as it’s finished charging I tend to remove it from the charger.

If it’s low on charge first thing in the morning, I’ll charge it up as soon as I get up so it’s charged by the time I leave the house.  I’m also going to remove the plug and cable from my bedroom so it’s not so much of a temptation just to charge it up before going to sleep.  I guess in some ways going green is all about making little changes to your life so that they eventually become habits and you don’t notice doing them anymore, which is what I hope to acheive with charging my phone.

I recently become aware of the fact that you can buy mobile phone timer devices that you can plug into the wall, set the timer, and then it will stop drawing power after the set duration.  I don’t know how you feel about these, but I personally feel a bit uneasy buying a gadget that’s taken resources and energy to produce when I can just get into the habit of charging my phone during the day.  What do you think about them?

Look out for another tip next Thursday, and in case you missed it here are energy saving tips one, two, and three.
