Visualizing the Critical Metals in a Smartphone
In an increasingly connected world, smartphones have become an inseparable part of our lives.
Over 60% of the world’s population owns a mobile phone and smartphone adoption continues to rise in developing countries around the world.
While each brand has its own mix of components, whether it’s a Samsung or an iPhone, most smartphones can carry roughly 80% of the stable elements on the periodic table.
But some of the vital metals to build these devices are considered at risk due to geological scarcity, geopolitical issues, and other factors.
Smartphone Part | Critical Metal |
---|---|
Touch Screen | indium |
Display | lanthanum; gadolinium; praseodymium; europium; terbium; dysprosium |
Electronics | nickel, gallium, tantalum |
Casing | nickel, magnesium |
Battery | lithium, nickel, cobalt |
Microphone, speakers, vibration unit | nickel, praseodymium, neodymium, gadolinium, terbium, dysprosium |
What’s in Your Pocket?
This infographic based on data from the University of Birmingham details all the critical metals that you carry in your pocket with your smartphone.
1. Touch Screen
Screens are made up of multiple layers of glass and plastic, coated with a conductor material called indium which is highly conductive and transparent.
Indium responds when contacted by another electrical conductor, like our fingers.
When we touch the screen, an electric circuit is completed where the finger makes contact with the screen, changing the electrical charge at this location. The device registers this electrical charge as a “touch event”, then prompting a response.
2. Display
Smartphones screens display images on a liquid crystal display (LCD). Just like in most TVs and computer monitors, a phone LCD uses an electrical current to adjust the color of each pixel.
Several rare earth elements are used to produce the colors on screen.
3. Electronics
Smartphones employ multiple antenna systems, such as Bluetooth, GPS, and WiFi.
The distance between these antenna systems is usually small making it extremely difficult to achieve flawless performance. Capacitors made of the rare, hard, blue-gray metal tantalum are used for filtering and frequency tuning.
Nickel is also used in capacitors and in mobile phone electrical connections. Another silvery metal, gallium, is used in semiconductors.
4. Microphone, Speakers, Vibration Unit
Nickel is used in the microphone diaphragm (that vibrates in response to sound waves).
Alloys containing rare earths neodymium, praseodymium and gadolinium are used in the magnets contained in the speaker and microphone. Neodymium, terbium and dysprosium are also used in the vibration unit.
5. Casing
There are many materials used to make phone cases, such as plastic, aluminum, carbon fiber, and even gold. Commonly, the cases have nickel to reduce electromagnetic interference (EMI) and magnesium alloys for EMI shielding.
6. Battery
Unless you bought your smartphone a decade ago, your device most likely carries a lithium-ion battery, which is charged and discharged by lithium ions moving between the negative (anode) and positive (cathode) electrodes.
What’s Next?
Smartphones will naturally evolve as consumers look for ever-more useful features. Foldable phones, 5G technology with higher download speeds, and extra cameras are just a few of the changes expected.
As technology continues to improve, so will the demand for the metals necessary for the next generation of smartphones.

Charting Grand Theft Auto: GTA’s Budget and Revenues
Dive into the GTA budget through the years, with GTA VI set to be the most expensive video game of all time.

Charting Grand Theft Auto: GTA’s Budget and Revenues
Over 10 years since the launch of Grand Theft Auto V (GTA V), the second most-sold video game in history, Rockstar Games has announced its sequel GTA VI will be “coming 2025.”
As the anticipation only grows for this next big entry in the franchise, we take a look at the GTA budget through the years. How much have the last two games cost to make, how much have they earned, and how do they compare with the latest entry?
Data for this visualization comes from Statista, TweakTown, and Twitch Metrics.
How Much Has GTA VI Cost to Make?
The GTA franchise has grown enormously in scale from humble beginnings as a top-down, 2D video game in 1997. Fifteen installments later, the upcoming release, GTA VI, is estimated to be the most expensive video game to be made yet.
Here’s a look at how much GTA VI and the last two major releases cost, and how much revenue they’ve earned as of August 2023.
Year | Title | Production Costs ($) | Revenue ($) | Copies Sold |
---|---|---|---|---|
2025 (est.) | GTA VI | $2B (rumored) | N/A | N/A |
2013 | GTA V | $265M | $7.7B | 185M |
2008 | GTA IV | $100M | $2B | 25M |
In 2008, GTA IV cost around $100 million—already a budget that rivalled big Hollywood releases. However with 25 million copies sold, the game earned nearly $2 billion—a five-fold return on its production cost.
Five years later, GTA V (2013) cost more than $200 million to make—twice GTA IV’s budget. A decade after its release, GTA V has generated close to $8 billion, with hundreds of millions in annual revenue from subscriptions and in-game purchases—a model that its successor is sure to follow.
In fact, subscription fees and in-game purchases represented 78% of Take-Two Interactive’s (parent of GTA developer Rockstar Games) revenues in 2023.
Analysts estimate the to-be-released GTA VI’s costs at $2 billion, including marketing and other expenses. A massive open-world (set in the Miami-inspired “Vice City”), cutting edge graphics, and a reportedly brand-new game engine are all reasons for the game’s outsized budget.
For comparison, the current most expensive games to have been made include Red Dead Redemption 2 (also by Rockstar) and Star Citizen, both reportedly with a $500 million budget.
Meanwhile, Take-Two Interactive shares are up more than 50% for the year.
