Stocklytics has shared a report on the top smartphones according to their radiation levels. While this may sound surprising, a good number of Xiaomi devices are on the top of the smartphone radiation list that the report has shared. Also, we see a Samsung phone coming very close to the top-ranked Xiaomi smartphones.
What’s Smartphone Radiation?
Ever wondered what happens when you hold your phone to your ear? Sure, you’re connecting with someone. However, there’s a little more going on behind the scenes. Smartphones rely on radiofrequency (RF) waves to transmit and receive signals. These waves emit a certain level of radiation, and that’s what we’re talking about today – smartphone radiation emission.
But is this radiation harmful? Well, that depends. To understand the potential risks, we need to introduce a key term. That would be the Specific Absorption Rate (SAR). SAR is a scientific measurement. It quantifies the rate at which your body absorbs RF energy from a radiation source, in this case, your smartphone. It’s expressed in watts per kilogram (W/kg).
Think of SAR as a way to gauge how much “radiation heat” your body is taking in. Regulatory bodies like the Federal Communications Commission (FCC) in the US and the European Commission set SAR limits for smartphones. These limits are established to ensure RF exposure stays within safe ranges for users.
A Closer Look At the Stocklytics Report
A recent report by Stocklytics highlights a concerning trend. It shows rising smartphone radiation levels. This echo growing worries about the environmental impact of technology. And it seems our favorite phone brands aren’t immune.
The report identifies Xiaomi and Samsung as major contributors. There are several models exceeding expectations. The Xiaomi Mi A1 stands out, emitting significantly high radiation. It’s a troubling 1.75 W/kg (ear) and 0.76 W/kg (body). Xiaomi’s Mi Max 3 series isn’t much better. It clocks in at 1.58 W/kg (ear) and a concerning 1.42 W/kg (body) for the non-5G model. The 5G variant boasts similar ear radiation but pushes body radiation even higher at 1.56 W/kg.
Samsung isn’t far behind. The A23 5G raises eyebrows with SAR levels near 1.5 W/kg for both ear and body. Even their popular foldable phones, the Galaxy Z Fold 4 and Z Fold 5, show concerning radiation levels. The Z Fold 4 reaches 1.30 W/kg (ear) and a surprising 1.51 W/kg (body). And the Z Fold 5 sits at 1.24 W/kg (ear).
The Smartphone Radiation Levels Are Expected to Rise
The report also sheds light on the potential impact of 5G technology. With its broader frequency range, 5G raises concerns about potentially higher radiation emissions from smartphones. This underlines the importance of manufacturers prioritizing safe design practices as 5G becomes more widespread.
Of course, as regulatory bodies are getting more conscious about smartphone radiation, we will see more manufacturers taking it into account. So, it’s possible that the upcoming network technologies on smartphones could result in lower emissions.
Should You Be Worried?
The Stocklytics report raises a valid concern. However, before you ditch your phone, here’s what you need to know.
First, it’s important to remember that regulatory bodies set SAR limits for a reason. These limits are in place to ensure our phones don’t emit radiation at harmful levels.
The report highlights specific models exceeding expectations. But it’s important to note that not all phones are created equal. Several brands offer models with demonstrably lower radiation output. For instance, Google Pixel 3a and 4a, and Apple’s iPhone 7 series all fall within a range of 1.36 W/kg to 1.39 W/kg (ear).
Even within Xiaomi and Samsung, there are exceptions. The report acknowledges that the Samsung Note 10 series, A55 and A35 series, and the Xiaomi Redmi 5A and Note 7 Pro all have relatively low SAR readings.
Ultimately, the decision is yours. If you’re concerned about radiation exposure, you can do some research to find a phone with a lower SAR rating. However, it’s important to remember that staying connected often outweighs the minimal risk posed by current radiation levels in most smartphones.
How Can You Lower Smartphone Radiation Exposure?
While the Stocklytics report raises concerns about certain phone models, there are ways to minimize radiation exposure from your smartphone. Here are a few tips:
Use a headset when making calls
When making calls, utilize a wired headset or speakerphone to keep your phone away from your head. This significantly reduces radiation absorption.
Reduce call duration
Shorter calls mean less exposure. Try to keep conversations concise when possible.
Keep Your Phone in Airplane mode When Signals Are Weak
In areas with weak signal strength, phones tend to emit higher radiation to connect to distant towers. Enable Airplane mode in such situations to minimize radiation.
Utilize Text Over Calls
Opt for text messages whenever possible. Texting eliminates the need to hold your phone to your ear, significantly reducing radiation absorption.
