If you’re reading this blog post on your smartphone, chances are you’re holding a little treasure in your hand. That’s right – your smartphone contains gold. But have you ever wondered how much gold is really inside your device?

What makes smartphones a gold mine?

Smartphones are not just devices for communication and entertainment; they are technologically advanced gadgets that house various precious metals and minerals. Gold is one of the most valuable and sought-after resources found in smartphones.

So, how much gold does an average smartphone contain?

An average smartphone contains about 0.034 grams of gold. While that may not seem like much, it adds up when you consider the billions of smartphones produced worldwide. In fact, it is estimated that the total amount of gold contained within all smartphones produced in a year could exceed 30 tons!

Where is the gold in smartphones located?

The gold in smartphones can be found in various components of the device. Here are the main areas where you’ll find traces of this precious metal:

  • Circuit boards: The printed circuit boards (PCBs) inside smartphones contain a thin layer of gold. This gold is used to establish reliable connections between different components.
  • Connectors: The connectors, such as SIM card slots and charging ports, also have gold plating. This enhances conductivity and prevents corrosion, ensuring a better user experience.
  • Screen: Smartphones with touch screens use indium tin oxide (ITO) as a transparent conductor. ITO is often deposited on a thin layer of gold, improving the touch sensitivity of the screen.
  • Other components: Gold can also be found in small amounts in other smartphone parts like speakers, microphones, and even in the bonding wires that connect different chips.

Why use gold in smartphones?

You might wonder why manufacturers choose to use gold in smartphones when there are other, less expensive alternatives available.

There are several reasons for using gold:

  • Reliability: Gold is highly conductive and resistant to corrosion, ensuring better signal transmission and a longer lifespan for your device.
  • Ease of use: Gold is easy to work with, making it an ideal material for fine electronics and delicate connections.
  • Value: Despite being more expensive than other metals, gold retains its value and can be easily recycled or recovered from old smartphones.

Final thoughts

So, before you trade in or throw away your old smartphone, think about the hidden treasure it holds. The gold inside your device might not make you an instant millionaire, but it certainly adds value to your pocket and the environment. Next time you scroll through your phone, remember that there’s more to it than meets the eye.
