There are a lot of people saying the SAR values is high and that is the only reason they are not buying the phone. Well, here are some facts about SAR.
What is SAR
SAR stands for Specific Absorption Rate, which is the unit of measurement for the amount of Radio Frequency (RF) energy absorbed by the body when for example using a mobile phone, walkie talkie, or working in very close to radio communication transmitting antennas. SAR is expressed in units of watts per kilogram (W/kg).
Does the SAR for a mobile phone vary when in use?
Yes. Although the SAR is determined at the highest certified power level in laboratory conditions, the actual SAR level of the phone while operating can be well below this value. This is because mobile phones use adaptive power control to reduce the transmitted power to the minimum possible whilst maintaining good call quality.
Once a call is established the mobile phone will power down to the minimum level required. Therefore, the closer you are to a base station and the better the reception, the lower the actual SAR level.
Does SAR vary between mobile phones?
Yes. The maximum SAR level for different mobile phone models can vary and this is primarily due to where the antenna in the phone is located. The International EMF Guidelines from ICNIRP are designed to protect people of all ages including children and incorporate large safety factors.

Are low SAR mobile phones safer?
No. Variations in SAR do not mean that there are variations in safety. While there may be differences in SAR levels among phone models, all mobile phones must meet RF exposure guidelines.
SAR levels can also vary considerably when in use depending on how good the reception is. Once a call is established the mobile phone will power down to the minimum level required to reach the network and maintain a quality call.
