A Breakdown of the Critical Metals in a Smartphone

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 PartCritical Metal
Touch Screen indium
Displaylanthanum; gadolinium; praseodymium; europium; terbium; dysprosium
Electronicsnickel, gallium, tantalum
Casingnickel, 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.

Mapped: The World’s Fastest (and Slowest) Internet Speeds

How quickly did this page load for you?

The answer depends on the device you’re using, and where in the world you’re located. Average internet speeds vary wildly from country to country.

Which countries have the fastest internet connection? Using data from the Speedtest Global Index™, this map ranks the fastest (and slowest) internet speeds worldwide, comparing both fixed broadband and mobile.

What Factors Affect Internet Speed?

Before diving in, it’s important to understand the key factors that impact a country’s internet speed. Generally speaking, internet speed depends on:

  1. Infrastructure or the type of cabling (copper or fiber-optic) that a country’s utilizing to support their internet service. Typically, the newer the infrastructure, the faster the connection.
  2. Proximity/connection to submarine cables is important, as these massive undersea fiber-optic cables transmit about 97% of the world’s communication data.
  3. The size of a country, since landmass affects how much it costs to upgrade infrastructure. The smaller the country, the cheaper it is to upgrade cabling.
  4. Investment makes a difference, or how much a country’s government prioritizes internet accessibility.

Of course, other factors may influence a country’s internet speed too, such as government regulation and intentional bandwidth throttling, which is the case in countries like Turkmenistan.

Ranked: Fixed Broadband Internet Speeds

The Speedtest Global Index uses data from hundreds of millions of people, in more than 190 countries, to measure both fixed broadband and mobile connections.

When it comes to the fastest fixed broadband, Singapore comes in first place, with a download speed of 262.2 mbps—more than double the global average.

Size could be a factor in Singapore’s speedy internet, as it’s one of the smallest
and also densest countries in the world. With a landmass of just 280 square miles, it’s around the same size as Austin, Texas.

The country’s government has also prioritized investment in digital infrastructure, especially in recent years. In 2020, the Singaporean government promised to invest $2.52 billion towards digital innovation, with a portion dedicated to upgrading the country’s telecom infrastructure.

At the opposite end of the spectrum, Cuba has the slowest fixed broadband, with a speed of 3.46 mbps. Along with poor government funding, Cuba also has limited access to submarine cables. While most countries are connected to several, Cuba is only connected to one.

Ranked: Mobile Internet Speeds

Mobile internet uses cell towers to wirelessly transmit internet to your phone. Because of this extra element, the ranking for mobile internet speeds varies from fixed broadband.

The United Arab Emirates (UAE) is first on the list, with a download speed of 195.5 mbps. Not only is mobile data fast in the UAE, it’s also relatively cheap, compared to other countries on the ranking. The average cost of 1 GB of data in the UAE is around $3.78, while in South Korea (#2 on the list) it’s $10.94.

The Future is 5G

Innovation and new technologies are changing the digital landscape, and things like 5G networks are becoming more mainstream across the globe.

Because of the rapidly changing nature of this industry, the data behind this ranking is updated monthly to provide the latest look at internet speeds across the globe.

This means the bar is gradually raising when it comes to internet speed, as faster, stronger internet connections become the norm. And countries that aren’t equipped to handle these souped-up networks will lag behind even further.

Ranked: Big Tech CEO Insider Trading During the First Half of 2021

Big Tech is worth trillions, but what are insiders doing with their stock? We breakdown Big Tech CEO insider trading during the first half of 2021.

Big Tech CEO Insider Trading During The First Half of 2021

When CEOs of major companies are selling their shares, investors can’t help but notice.

After all, these decisions have a direct effect on the personal wealth of these insiders, which can say plenty about their convictions with respect to the future direction of the companies they run.

Considering that Big Tech stocks are some of the most popular holdings in today’s portfolios, and are backed by a collective $5.3 trillion in institutional investment, how do the CEOs of these organizations rank by their insider selling?

CEOStockShares Sold H1 2021Value of Shares ($M)
Jeff BezosAmazon (AMZN)2.0 million$6,600
Mark ZuckerbergFacebook (FB)7.1 million$2,200
Satya NadellaMicrosoft (MSFT)278,694
$65
Sundar PichaiGoogle (GOOGL)27,000$62
Tim CookApple (AAPL)0$0

Breaking Down Insider Trading, by CEO

Let’s dive into the insider trading activity of each Big Tech CEO:

Jeff Bezos

During the first half of 2021, Jeff Bezos sold 2 million shares of Amazon worth $6.6 billion.

This activity was spread across 15 different transactions, representing an average of $440 million per transaction. Altogether, this ranks him first by CEO insider selling, by total dollar proceeds. Bezos’s time as CEO of Amazon came to an end shortly after the half way mark for the year.

Mark Zuckerberg

In second place is Mark Zuckerberg, who has been significantly busier selling than the rest.

In the first half of 2021, he unloaded 7.1 million shares of Facebook onto the open market, worth $2.2 billion. What makes these transactions interesting is the sheer quantity of them, as he sold on 136 out of 180 days. On average, that’s $12 million worth of stock sold every day.

Zuckerberg’s record year of selling in 2018 resulted in over $5 billion worth of stock sold, but over 90% of his net worth still remains in the company.

Satya Nadella

Next is Satya Nadella, who sold 278,694 shares of Microsoft, worth $234 million. Despite this, the Microsoft CEO still holds an estimated 1.6 million shares, which is the largest of any insider.

Microsoft’s stock has been on a tear for a number of years now, and belongs to an elite trillion dollar club, which consists of only six public companies.

Sundar Pichai

Fourth on the list is Sundar Pichai who has been at the helm at Google for six years now. Since the start of 2021, he’s sold 27,000 shares through nine separate transactions, worth $62.5 million. However, Pichai still has an estimated 6,407 Class A and 114,861 Class C shares.

Google is closing in on a $2 trillion valuation and is the best performing Big Tech stock, with shares rising 60% year-to-date. Their market share growth from U.S. ad revenues is a large contributing factor.

Tim Cook

Last, is Tim Cook, who just surpassed a decade as Apple CEO.

During this time, shares have rallied over 1,000% and annual sales have gone from $100 billion to $347 billion. That said, Cook has sold 0 shares of Apple during the first half of 2021. That doesn’t mean he hasn’t sold shares elsewhere, though. Cook also sits on the board of directors for Nike, and has sold $6.9 million worth of shares this year.

Measuring Insider Selling

All things equal, it’s desirable for management to have skin in the game, and be invested alongside shareholders. It can also be seen as aligning long-term interests.

A good measure of insider selling activity is in relation to the existing stake in the company. For example, selling $6.6 billion worth of shares may sound like a lot, but when there are 51.7 million Amazon shares remaining for Jeff Bezos, it actually represents a small portion and is probably not cause for panic.

If, however, executives are disclosing large transactions relative to their total stakes, it might be worth digging deeper.
