LG G4 Safety Tip: Turning Off Wi-Fi and Bluetooth Reduces Radiation.

This SAR chart reveals how turning off Wi-Fi and Bluetooth on your LG G4 can significantly reduce your exposure to radiation. Our SAR comparison chart shows that by simply turning off these transmitters, you can lower the RF radiation exposure to your head by %, and you can lower exposure to the body by %, when considering these differences between cellular-only (Wi-Fi/Bluetooth OFF) and simultaneous use exposure (Wi-Fi/Bluetooth ON), a wise way to reduce excessive phone radiation is to tap off unnecessary transmitters when not in use. Additionally, when using your phone as a hotspot, turning off Bluetooth can reduce your exposure by up to 100% according to the FCC SAR report for device number ZNFH815.

The Specific Absorption Rate (SAR) of a mobile device measures the amount of radio frequency energy absorbed by the body during device usage.

The SAR values for the g4 (FCC ID ZNFH815) are as follows:

  • 0.72 W/kg when held at the head with cellular transmission only
  • 0.75 W/kg when worn on the body with cellular transmission only
  • 1.18 W/kg when used as a Hotspot or Airplay
  • 0 W/kg when held at the head with simultaneous cellular and Wi-Fi transmission
  • 0 W/kg when worn on the body with simultaneous cellular and Wi-Fi transmission
  • when used as a Hotspot simultaneously with other transmitters active.

    SIMStandard SIM
    SIM (Subscriber Identity Module) is a small card that contains mobile network subscriber's account information. This allows the phone using the card to attach to a mobile network. The SIM card is most commonly associated with GSM and UMTS mobile networks. Moving a SIM card from one phone to another allows a subscriber to switch mobile phones without having to contact their mobile network carrier. SIM cards can also be used by a phone to store limited amounts of data, such as phone numbers and text messages.
