Jakarta, Indonesia Sentinel — All smartphones emit radiation, but some models surpass others in terms of the amount they produce. The level of smartphone radiation is measured using the Specific Absorption Rate (SAR), which quantifies how much energy from radio frequencies is absorbed by the human body.
The U.S. Federal Communications Commission (FCC) has set the maximum permissible SAR value at 1.6 watts per kilogram (w/kg). However, a report by Bankless Times highlights that several smartphone models emit radiation levels close to or even exceeding this limit.
Factors Affecting Radiation Emission
The radiation emitted by a smartphone varies due to multiple factors, including:
- Device Type and Model: Newer devices often have better antenna technology to reduce emissions.
- Age of the Device: Older models may emit higher radiation due to outdated components.
- Antenna Strength: A weaker antenna might need more power to connect, leading to higher emissions.
- Proximity to Cell Towers: Devices emit more radiation when far from towers due to increased signal power demands.
Smartphones with the Highest Radiation
The report identifies the top 10 smartphones with the highest SAR values, based on data from Gizchina. Notably, the Motorola Edge tops the list with a SAR value of 1.79 w/kg, exceeding the FCC’s safety limit. Here’s the full list:
- Motorola Edge: 1.79 w/kg
- ZTE Axon 11 5G: 1.59 w/kg
- OnePlus 6T: 1.55 w/kg
- Sony Xperia XA2 Plus: 1.41 w/kg
- Google Pixel 3XL: 1.39 w/kg
- Google Pixel 4a: 1.37 w/kg
- Oppo Reno5 5G: 1.37 w/kg
- Sony Xperia XZ1 Compact: 1.36 w/kg
- Google Pixel 3: 1.33 w/kg
- OnePlus 6: 1.33 w/kg
The Case of Motorola Edge
The Motorola Edge, released several years ago, takes the lead with the highest SAR rating of 1.79 w/kg. This value surpasses the FCC threshold, raising concerns about prolonged exposure to radiofrequency energy.
Are These Phones Still in Use?
Most of the phones listed are older models, released between two and five years ago. As a result, they may not be widely used today. However, users of these models should be aware of potential health risks associated with high SAR values.

Mitigating Radiation Risks
While the risks associated with phone radiation remain a topic of debate, users can take precautions to minimize exposure:
- Use Speakerphone or Headphones: Avoid holding the phone directly against your ear.
- Limit Call Duration: Keep phone calls short or switch to texting.
- Keep Distance: Avoid placing the phone near your body, especially while sleeping.
- Use Airplane Mode: When not actively using the device, turn on airplane mode to reduce radiation.
Conclusion
Awareness of SAR values is essential for smartphone users, especially for those concerned about potential health impacts. While the devices listed above exhibit high radiation levels, adopting safer usage habits can help mitigate risks. As technology evolves, newer smartphones are expected to come with improved designs that prioritize user safety.
Understanding the radiation levels of your device is a step toward making informed decisions about your tech usage.
