What Causes My Body To Make Batteries Drain?

I have noticed this with watch batteries, cell phone batteries, electric toothbrush batteries and laptop batteries. If it touches me it will drain faster than the batteries that others replace considerably sooner than my husband, and others. If I use my husband's cell phone, for a short amount of time, his will drain right away. Otherwise his can stay powered for days. We have wondered why my new cell phone batteries seem to die within a couple of months or less, and my husband's last a year or more. Is it high iron content or magnetism, or what?
