DZERO Hates Cell Phones September 20, 2006Posted by gordonwatts in computers, physics life.
Every DZERO shifter knows to turn off their cell phone when they are on shift. Our Control Room is 4 stories underground and no cell phone signal reaches it. I’d always thought the phone goes into search mode and wastes a lot of energy broadcasting to a cell site that can’t be reached, and thus the battery drain. Actually, I always thought that it was poor design in the cell phone to let that happen!
Then I went to the summer cottage in Ottawa. There is no cell service out there. And my current phone’s battery lasts forever. “Ah Ha!” I thought — finally a cell phone that doesn’t chew up batteries when there is no cell site around.
Wrong! During one of my eight hour shifts here at DZERO my cell phone will go from 100% charged to about 10% charged! Normally it lasts almost 2 days without a charge! There is something about this location that causes the cell phone to really waste a lot of energy. It’s a mystery to me!
