Having already revealed the current phones which emit the most radiation, this chart looks at the opposite end of the scale. While conclusive longitudinal research on the effects of cell phone radiation is still hard to come by, for those looking to minimize the risks, this list may be useful.
SAR values of mobile phones
The specific absorption rate (SAR) is a measure for the energy absorbed by the body. Its measure is Watt per kilogram (W/kg). In order to avoid adverse health effects, the specific absorption rate of a mobile phone must not exceed 2 Watts per kilogram

Less is better
Interestingly, Samsung is truly committed to making very safe phones. Apple on the hand is struggling hard to just meet the psychological safe phones. Another astonishing fact is all their SAR numbers are just shy of 1.0. Is it too close for comfort?
While there is no universal guideline for a 'safe' level of phone radiation, the German certification for environmental friendliness 'Der Blaue Engel' (Blue Angel) only certifies phones which have a specific absorption rate of less than 0.60 watts per kilogram. All of the phones featured here are well under this benchmark.
The German Federal Office for Radiation Protection (Bundesamt für Strahlenschutz) has a comprehensive database of smartphones - new and old - and the level of radiation they emit when held to the ear during a call. Following the criteria set for this chart (see footnotes), the smartphones creating the lowest level of radiation are the ZTE Blade V10 and the Axon Elite - with a specific absorption rate of 0.13 and 0.17 watts per kilogram, respectively. Alongside ZTE, Samsung handsets feature prominently, with five out of eight of the smartphones on this ranking coming from the South Korean company.
