One of my relatives claims that returning a cordless phone (not cell
phone) to the charging cradle after each use will wear down the
charging contacts. Is this true? I can't find anything about this
anywhere and can only assume it's wrong. |

Yes, it's true, but you'd have to live till you were about 200 years old
to witness it. More than likely they'll just get dirty from time to time.
People who leave cordless phones out of the cradle until they go flat
are about as annoying as Paris Hilton.

Your assumption would be pretty safe. Whatever tiny amount of wear
occurs (and, technically, there is wear ANY time two surfaces rub
together) in such a situation would be negligible to anyone not
inspecting the contacts with a microscope.
Keep the peace(es).

If the contacts get dirty, buff them with a pencil eraser.
Your relative is a strange one; isn't he? |

some the contacts are only good 10000 cycles or so

and you'd be mostly right, lots of phones are using solid stainless steel or
chrome plated contacts, and these basically last forever.

The charging contacts are generaly a fairly heavy guage of metal to
easily wear down. If your cordless phone is using a silver hydride or
similiar type battery that has no memory problems as like the older
Nicad batteries, there should be no problem. Most likely, you will wear
out the phone before you wear out the contacts!
The average lifespan of chargeable batteries is about 3 to 4 years.
Sometimes they last longer.
