Just How Energy Efficient is Your Smart Phone?
Smart phones have become so effective and reliable that they have replaced dozens of other devices you might otherwise carry. A smart phone can let you take pictures, listen to downloaded music, browse your favorite internet site, write emails, log on to your social media sites, and perform hundreds of other tasks. Many people are actually giving up personal computers altogether because of everything their smart phone can accomplish. If there is one drawback to the device that allows you to do so much, it’s that it takes so much energy to run all these different programs.
Many who own smart phones are finding that they need to plug in their phone every day or every other day, and they may wonder how much energy they are using to charge them up to full power. It can also be a concern in a household where everyone has their own smart phone and is constantly plugging them in. The truth is that while you need to constantly plug in your smart phone and recharge it, the cost of doing so is miniscule. The reason they need to be charged so often is not that they use so much electricity to run, but that their batteries are so small and carry such a small amount of power for them.
It is also good to know that today’s smart phones use a very small amount of energy when compared with other electrical devices. For example, your standard laptop, when left plugged in all year long, will average around $10 (6,28 ₤) worth of electricity for a year. A desktop PC will use considerably more, usually around $30 (18,84 ₤) per year. A 42” plasma television, when left plugged in, will use around $50 (31,41 ₤) per year for electricity. When you compare the energy consumption of your smart phone to these other common devices, it is easy to see that its energy consumption is of little concern.
You can make your smart phone more energy efficient by turning it off when not in use and dimming the backlight, or reducing the amount of time the light stays on when you turn on the screen. These tasks can be burdensome however and can detract from the use of your smart phone. If you are looking to save money on electricity, you might be better off thinking about how to reduce the cost of many appliances, such as turning off your hot water heater during the day and unplugging your TV at night. These simple steps will cut down on your electricity consumption and allow you to use your smart phone freely, without worrying about its energy consumption.
