What has the highest SAR value?
The FCC measures this via the Specific Absorption Rate (SAR), with the maximum acceptable value pegged at 1.6 W/kg. The lower your mobile phone's SAR is, the less radiation it emits.
The current lowest radiation smartphone (by SAR rating) is the Verykool Vortex RS90 with a SAR rating of . 18 w/kg.

As per FCC, the permissible limit for public exposure from cell phones is a SAR level of 1.6 watts per kilogram (W/kg). Hence, any cell phone at or below this SAR level is considered to be safe.
The SAR value is the rate at which the body absorbs this lost electromagnetic waves. According to US Federal Communications Commission (FCC), phones with a SAR level of 1.6 W/Kg for body or below are deemed safe. The same measurement is followed in India.
This device has a SAR value of 1.78watts/kg which is hazardous to health. The allowed SAR value in India is 1.6watts/kg. Radiations are heavy from this device.
The SAR limit recommended by the Council of the European Union is 2.0W/kg averaged over 10 g of actual tissue.
While there has been a lot of talk about the phones with high SAR (specific absorption rate) value can potentially damage the body at a cellular level, particularly when you hold the phones against your ears and talk on them, not enough attention has been paid by smartphone users to the damage that these devices the ...
Specific Absorption Rate (SAR) is a measure of the amount of RF power deposited in the human head or body whenever a mobile phone or other wireless radio device transmits. It is the maximum SAR value (in units of Watts/kilogram) that is measured during SAR compliance testing.
If you're concerned about your SAR risks, but don't feel like the hassle of keeping your phone at a distance all the time, these are the phones known to emit the least radiation: the Samsung Galaxy Note10+ 5G (0.19 w/kg); Samsung's Galaxy Note10 (0.21 w/kg); the Samsung Galaxy A80 (0.22 w/kg); LG G7 ThinQ (0.24 w/kg); ...
What is the safest cell phone?
Samsung Galaxy Note 20 Ultra
Your Note 20 Ultra has multi-layered security created by this security platform. You will get security improvements designed expressly for the Android OS, encryption, and TrustZone architecture to safeguard critical data.
Use speaker mode, head phones, or ear buds to place more distance between your head and the cell phone. Avoid making calls when the signal is weak as this causes cell phones to boost RF transmission power. Consider texting rather than talking - but don't text while you are driving.
The FCC limit for public exposure from cellular telephones is an SAR level of 1.6 watts per kilogram (1.6 W/kg).
The SAR level of any device should not exceed 1.6 W per Kg.
SAR values increase as the conductivities of human body tissues increase and usually decrease as the increase of relative permittivities of human body tissues increase. The effect of the dielectric values of human body on SAR is orientation, human body and frequency dependent.
So how much SAR is better? Lower is better, although as noted earlier FCC in the US considers SAR level of 1.6W/kg good enough. So don't worry if your phone has a SAR value of 1.2 or something like that even though most phones are nowadays in the range of 0.5 to 0.6.
According to IEC standard 60601-2-33, the maximum SAR limit for the whole body is 2.0 W/kg, and the maximum temperature limit is 39 °C and the core temperature increase is limited to 0.5°C6.
iPhone 13 Pro Max RF Exposure Information
The SAR limit is 1.6 watts per kilogram in countries that set the limit averaged over 1 gram of tissue, and 2.0 watts per kilogram in countries that set the limit averaged over 10 grams of tissue.
iPhone 12 Pro RF Exposure Information
The SAR limit is 1.6 watts per kilogram in countries that set the limit averaged over 1 gram of tissue, and 2.0 watts per kilogram in countries that set the limit averaged over 10 grams of tissue.
A whole-body average SAR of 0.4 W/kg has been chosen as the restriction that provides adequate protection for occupational exposure. An additional safety factor of 5 is introduced for exposure of the public, giving an average whole-body SAR limit of 0.08 W/kg.
What is the SAR limit for WIFI?
The SAR is a measure of the rate that RF energy is absorbed by the body. For exposure to RF energy from wireless devices, the allowable FCC SAR limit is 1.6 watts per kilogram (W/kg), as averaged over one gram of tissue.
Maximum Simultaneous SAR value. 1.36W/kg. Regarding 5G terminals: Unlike previous technologies, the current 5G in the 3.5 GHz band requires the phone to use two networks simultaneously, the 4G network and the 5G network.
- Avoid or minimize use of high SAR sequences (in the box above). ...
- Use Gradient Echo instead of Spin Echo sequences where possible. ...
- Reduce initial RF flip angle (α). ...
- Increase TR (without increasing # of slices). ...
- Decrease # of slices (without reducing TR). ...

First level controlled operating mode.
This level is defined as one where certain imaging parameters may cause physiologic stress (such as peripheral nerve stimulation or tissue heating). Active medical supervision is required to use this mode to insure that a careful assessment of benefits vs risks have been assessed.
The Federal Communications Commission (FCC) sets the maximum SAR limit for mobile phones at 1.6 W/kg in the US. This limit is based on guidelines from the International Commission on Non-Ionizing Radiation Protection (ICNIRP) and is considered safe for public exposure.
Can iPhone Radiation Hurt You? Probably not. The radiation given off by iPhones isn't ionizing and is on the lower end of the electromagnetic spectrum, far from being dangerous like a UV light. Your iPhone will definitely not make you sick after using it for a few days.
Cell phones emit low levels of non-ionizing radiation when in use. The type of radiation emitted by cell phones is also referred to as radio frequency (RF) energy. As stated by the National Cancer Institute, "there is currently no consistent evidence that non-ionizing radiation increases cancer risk in humans.
The report claims the iPhones had an average radiation SAR of 1.166 watts per kilogram (W/kg) whereas the Samsung devices that launched this year had an average of 0.517W/kg.
Based on interest, it's likely Android phones get hacked more than iPhones. The two-factor authentication platform Rublon reported that there was 13 times more interest in hacking Android phones than iPhones in 2021.
Purism Librem 5
From the entire list of smartphones that don't track you, the Librem 5 is the best option. The phone runs PureOS, Purism's privacy-focused Linux operating system which is not based on Android nor iOS. As such, the software is open-source and comes with free and open-source software (FOSS) pre-installed.
Are Apple phones safer than Android?
security. While iOS may be considered more secure, it's not impossible for cybercriminals to hit iPhones or iPads with malicious software. Because of this, the owners of both Android and iOS devices need to be aware of possible malware and viruses, and be careful when downloading apps from third-party app stores.

Specific Absorption Rate (SAR) measures the amount of RF energy absorbed by a human or animal body. SAR testing must be done on all wireless devices that have radiating parts closer than 20 cm to the human body or head.
While SAR values are an important tool in judging the maximum possible exposure to RF energy from a particular model of cell phone, a single SAR value does not provide sufficient information about the amount of RF exposure under typical usage conditions to reliably compare individual cell phone models.
So how much SAR is better? Lower is better, although as noted earlier FCC in the US considers SAR level of 1.6W/kg good enough. So don't worry if your phone has a SAR value of 1.2 or something like that even though most phones are nowadays in the range of 0.5 to 0.6.
