Cool tips

If your cellphone loses its battery charge too quickly while idle in your pocket, part of the problem may be that your pocket is too warm.

“Cellphone batteries do indeed last a bit longer if kept cool,” says Isidor Buchanan, editor of the Battery University Web site. The 98.6-degree body heat of a human, transmitted through a cloth pocket to a cellphone inside, is enough to speed up chemical processes inside the phone’s battery. That makes it run down faster. To keep the phone cooler, carry it in your purse or on your belt.

This same method can be used to preserve your battery should you find yourself away from home without your charger. Turn off the phone and put it in the hotel refrigerator overnight to slow the battery’s natural tendency to lose its charge.

Good idea, huh? Sort of redefines "cold calling." Of course you have to have a hotel. And a refrigerator. But hey, other than that...

Suppose your remote car door opener does not have the range to reach your car across the parking lot. Hold the metal key part of your key fob against your chin, then push the unlock button. The trick turns your head into an antenna, says Tim Pozar, a Silicon Valley radio engineer.

I wonder if you can pick up digital TV that way.
