How long does silver last in a cell phone or computer
The modern life cycle of cell phones, music listening and computers is limited to about two years for most owners around the world.

How much is the gold in a cell phone worth
For example, did you know that it only takes about 41 mobile phones to earn a fantastic 1g? The price of gold is now around $1,700 (£1,365) an ounce, which equates to about $60 a gram. So each discarded device contains about $1.50 worth of gold.
What old cell phones are valuable
Those old cell phone calls you’ve hidden in your desk drawer not only take up valuable space in your home, they can’t do the same for the great new planet. Mobile phones contain valuable assets including gold, silver, copper, zinc and silver.
