Measuring iPhone RF Radiation: SAR Rating
To ensure public safety, the Federal Communications Commission (FCC) requires manufacturers to conduct tests on the Specific Absorption Rate (SAR) of their devices. SAR measures the amount of RF radiation absorbed by the human body when using a cell phone. A lower SAR rating indicates lower RF radiation emission.
| iPhone Model | SAR Rating (Head) | SAR Rating (Body) |
|---|---|---|
| iPhone 12 | 1.18 W/kg | 1.17 W/kg |
| iPhone 11 | 1.15 W/kg | 1.16 W/kg |
| iPhone XR | 1.12 W/kg | 1.14 W/kg |
As you can see from the table above, the SAR rating for iPhones is well within the FCC’s safety limit of 1.6 W/kg.
Minimizing Exposure to RF Radiation from iPhones
While iPhones do emit RF radiation, there are steps you can take to minimize your exposure:
Use a Headset or Speaker
Using a headset or speaker can significantly reduce RF radiation exposure by increasing the distance between the iPhone and your head.
Text or Email Instead
Whenever possible, opt for texting or emailing instead of making calls to reduce RF radiation emission.
Use Airplane Mode
Enable airplane mode when not in use to prevent your iPhone from emitting RF radiation.
Keep Your iPhone Away from Your Body
Try to keep your iPhone at least 10 mm away from your body to reduce RF radiation exposure.
Conclusion
In conclusion, iPhones do emit radio frequency radiation, but the amount emitted is well within the safety limits set by the FCC. By taking simple precautions to minimize exposure, you can enjoy the benefits of wireless communication while protecting your health. Remember, it’s always better to be informed and take proactive steps to ensure a healthier and safer relationship with your iPhone.

What is radio frequency and how does it relate to iPhones?
Radio frequency (RF) refers to a type of electromagnetic energy that is used to transmit signals wirelessly between devices. In the context of iPhones, RF is used to enable various wireless communication functions such as making and receiving calls, sending texts, and accessing the internet. However, the use of RF energy has raised concerns about potential health risks, as it has been linked to cancer and other adverse health effects.
The iPhone, like all cellular devices, emits RF energy when it is in use. This energy is emitted by the phone’s antenna, which is usually located in the back of the device. The amount of RF energy emitted by an iPhone can vary depending on various factors, such as the strength of the cellular signal, the type of iPhone model, and the usage patterns of the user. While some studies have suggested a possible link between RF energy and health risks, the scientific consensus is that the RF energy emitted by iPhones is within safe limits set by regulatory agencies such as the Federal Communications Commission (FCC).
How does iPhone’s radio frequency emission compare to other devices?
The iPhone’s RF emission levels are comparable to those of other cellular devices on the market. In fact, the FCC sets a specific absorption rate (SAR) limit of 1.6 watts per kilogram (W/kg) for all cellular devices, and iPhone models have been found to emit RF energy well within this limit. For example, the iPhone 12 Pro has a SAR rating of 0.99 W/kg, which is significantly lower than the FCC’s maximum allowed limit.
It’s worth noting that RF emission levels can vary across different devices and models, and some devices may emit higher levels of RF energy than others. For example, some smartphones from other manufacturers may have higher SAR ratings than iPhone models. However, the overall consensus is that modern cellular devices, including iPhones, are designed to minimize RF emission levels and meet or exceed regulatory safety standards.
