Xiaomi lowers the intensity of the waves of the Redmi Note 9 Pro, which was excessive


The National Frequencies Agency has required Xiaomi to greatly reduce the intensity of the waves emitted by the Redmi Note 9 Pro. The manufacturer complied.

If you have a Xiaomi Redmi Note 9 Pro, you must have received a very discreet smartphone upgrade. This was not intended to provide a new function or correct a software bug, but rather to reduce the intensity of the waves emitted by the phone, at the request of the National Frequency Agency (ANFR). A statement to this effect was released on July 28.

In this case, the Xiaomi Redmi Note 9 Pro was “flashed” at 4.96 W/kg (watts per kilogram). This index designates the SAR: specific absorption rate. Indicates the part of energy carried by electromagnetic waves that is absorbed by the human body. The higher this value, the higher the energy. Therefore, this value should be as low as possible.

The SAR has three regulatory thresholds, for the trunk, head, and extremities. For Xiaomi, the problem was in the extremities. Thanks to the update, the SAR has been reduced to 2.69 W/kg, knowing that the regulatory limit for this part of the body is 4 W/kg. In short, the intensity of the waves has been practically halved.

In principle, the owner of this phone model has nothing to do: the update is supposed to be sent automatically as soon as the terminal is connected to a data network (mobile or Wi-Fi). If in doubt, check that the system version you have installed on your phone is at least MIUI 12.5.8.0 (RJZEUXM).
