Radiation Emissions of Popular Smartphones

Smartphones have become an integral part of our everyday lives. From work and school to daily tasks, these handheld devices have brought everything into the palm of our hands.

Most people spend 5-6 hours on their phones each day. And, given that our phones emit a tiny amount of radiation, we’re exposing ourselves to radiation for hours each day.

But different phones emit different amounts of radiation.

With the help of data collected by the German Federal Office of Radiation Protection, we visualize the radiation emissions of some popular smartphones in the market today.

Radiation and SAR Values of Smartphones

Smartphones and other mobile devices emit tiny amounts of radiofrequency (RF) radiation. Humans can absorb this radiation when the smartphone is being used or is lying dormant anywhere near their bodies.

The parameter used to measure phone radiation emissions is the Specific Absorption Rate (SAR). It is the unit of measurement that represents the quantity of electromagnetic energy absorbed by the body when using a mobile device.

The Council of the European Union has set radiation standards for cell phones at 2 watts per kilogram, measured over the 10 grams of tissue that is absorbing the most signal.

SAR values are calculated at the ear (speaking on the phone) and at the body (kept in your pocket). For the purposes of this article, we’ve used the former calculations.

Smartphones With the Highest Levels of Radiation Emissions

The Motorola Edge has the highest radiation emission with a SAR value of 1.79 watts of radiation per kilogram. That’s significantly higher than most other smartphone models in the market today and close to the limits set by the EU for cellphones.

Coming in second is the Axon 11 5G by ZTE with 1.59, followed by the OnePlus 6T at a close third with 1.55 W/kg. The Sony Experia AX2 Plus with 1.41 and the Google Pixel 3 XL and 3A XL at 1.39 round out the top five.

Here is a look at the 10 smartphones that emit the highest level of radiation:

Smartphones with the lowest level of radiation

Now that we have detailed the worst offenders let’s look at the smartphones with the lowest levels of radiation emissions.

Smartphones With the Lowest Levels of Radiation Emissions

The smartphone with the lowest SAR value is the ZTE Blade V10, with 0.13 watts of radiation per kilogram.

Mobile devices by Samsung carry some of the least radiation risks. The company has four phones considered to be the best in the category. The Galaxy Note 10+ is the best model in their line-up, emitting a meager 0.19 watts per kilogram.

Here is a look at the 10 smartphones that emit the lowest levels of radiation:

There is currently no significant research proving the harmful effects of phone radiation.

Despite this, people who are in contact with their devices for extended periods can at least quantify their radiation exposure and make choices about which brands serve their needs.

The World’s Biggest Cloud Computing Service Providers

Cloud computing service providers generated $270 billion in revenues last year, concentrated among a few giants.

Today, the three largest cloud computing service providers command 66% of the global market.

Amazon, Microsoft, and Google have generated billions in revenues through their cloud infrastructure that provide the computing power companies need to store data. What’s more, most AI models are run on the cloud, creating a surge in computing demand for cloud providers.

The above graphic shows the largest cloud providers globally, based on data from Synergy Research Group.

Breaking Down the Cloud Market

Here are the world’s top cloud computing service providers based on enterprise revenues as of the fourth quarter of 2023:

ProviderCountryMarket Share Q4 2023
Amazon Web Services🇺🇸 U.S.31%
Microsoft Azure🇺🇸 U.S.24%
Google Cloud🇺🇸 U.S.11%
Alibaba Cloud🇨🇳 China4%
Salesforce🇺🇸 U.S.3%
IBM Cloud🇺🇸 U.S.2%
Oracle🇺🇸 U.S.2%
Tencent Cloud🇨🇳 China2%
Other🌐 Other21%

With 31% of the global market share, Amazon’s cloud division posted $24.2 billion in revenues over the quarter.

AWS is a major cash engine for the company, but growth slowed over 2023 as enterprises and startups cut back on tech spending. Annual sales growth compared to the same quarter last year grew by 13%—far below competitors Microsoft and Google, whose cloud divisions grew by 30% and 26%, respectively.

As we can see, U.S. firms make up the lion’s share of the market, while China’s Alibaba Cloud and Tencent Cloud together comprise 5% of the global share.

The AI Boom and the Cloud

Given that a significant chunk of AI models are run on the cloud, the industry may be positioned to see greater demand as momentum accelerates.

In fact, newer AI systems are as much as 10 to 100 times larger than older models. In line with this, major cloud providers are seeing high demand for cloud services to allow companies across financial to manufacturing sectors to run large language models on their platforms.

Today, 98% of companies globally rely on the cloud for at least one part of their business applications, which may present a market opportunity for the industry as advancements in AI continue to grow.
