Update information

About Specific Absorption Rate (SAR)

This product has been designed to comply with the technical standards ^*1 set by the government regarding the human absorption of radio waves, as well as the radio wave protection limits recommended by equivalent international guidelines. These international guidelines were established by the International Commission on Non-Ionizing Radiation Protection (ICNIRP), which is in collaboration with the World Health Organization (WHO), and the limits include a sufficient safety margin for all users, regardless of their age or health condition.
National technical standards and international guidelines define the permissible value for radio wave protection as the Specific Absorption Rate (SAR), which represents the average amount of radio wave energy absorbed by the human body, and the permissible SAR value for mobile phones is 2.0 W/kg.
The maximum SAR value for this product [Samsung Galaxy A25 5G] at the side of the head is 1.125W/kg, ^and the maximum SAR value when worn on the body is 0.423W/kg ^*3. Although there may be slight differences in SAR depending on the individual product, all of them meet the allowable value. Mobile phones are designed to have the minimum transmission power required for communication with mobile phone base stations, so when actually making a call, the SAR value is usually smaller. In general, the closer the distance from the base station, the smaller the output of the mobile phone.

*1 Technical standards are stipulated in the Radio Law-related Ministerial Ordinance (Article 14-2 of the Radio Equipment Regulations).
*2 This product can be used in positions other than on the side of the head. By using accessories such as a carrying case to keep the device at least 1.5 cm away from the body and without any metal (parts) between the device and the body, this product complies with national technical standards and international guidelines for radio wave protection.
*3 This value is the value for simultaneous transmission.

The World Health Organization has stated that "Numerous studies have been conducted over the past 20 years to assess whether mobile phones pose a potential health risk. To date, no adverse health effects have been established as being caused by mobile phone use."
