SAR explained: here is the radiation level of top smartphones (iPhone 6 compared with competition)

Have you heard about SAR? The acronym stands for Specific Absorption Rate and relates to the radiation exposure levels of electronic devices. It’s an important measurement for human health and that’s why all phones undergo careful evaluation of their SAR by the Federal Communications Commission (FCC) in the United States.

The legal limit for a device to pass testing is 1.6 watts per kilogram (W/kg), averaged over one gram of tissue, and interestingly enough many of the top-rated smartphones out there approach it dangerously closely.

One such barely legal device is the Apple iPhone 6. Did you know that SAR levels for the iPhone 6 are merely .01 below the legal 1.6 W/kg limit? While technically it is under the threshold, we’d definitely be more reassured if Apple’s newest big thing had lower levels of SAR. Is there an explanation for this? We’d guess that it might have something to do with the iPhone 6’s record number of LTE bands, but take this as merely an educated guess.

And did you know that you can check the SAR for any smartphone on Just type in the name of the device in our search bar, select the specification page for that phone, click ‘TO SEE THE FULL SPECIFICATIONS WITH IN-DEPTH DETAILS CLICK HERE’ (located right below the availability tab). That’s all it takes!

Apple puts the SAR up near the limit as it nearly impossible to fry the "brain" of an iZombie.

Hail the king of phone radiation. I wonder what are the SAR scores of the previous iPhone models? Oh right, no need to see it iZombies are proof enough.

Pong makes a case that reduces the EMF exposure to about 1/3 of what is produced without the case. Unfortunately, no RF-reducing case from Pong as yet. Pong reduces the SAR for the 5 by 5X from the legal max SAR limit:

Don’t get played by Pong cases, cell phone radiation is no game -- SAR testing can only guard aganst hazards caused by heat. Heat isn't even the issue as health effects are proven at below thermal levels. You need a phone case that blocks radiation, not just lowers SAR levels. You can lower SAR hundreds times more than the Pong case simply by iPhone users changing to a Galaxy Note device. Do a search on Pong Case vs RF Safe Case

Taking your claims at face value, it seems that the RF Safe case only provides protection with the flip cover in place (covering the screen of the phone). I don't know many smartphone users who keep a flip cover in place when taking a call. The cover gets opened to see who is calling and then the cover remains opened to take the call. Net-net, it seems the protection is negated by normal use. Better to buy a phone with low radiation output if radiation exposure is a concern. Or, use ear buds or other means of reducing the exposure.

Most smartphone users don't have to look at the screen after answering the call. Close the shielded flip cover to keep microwave shielding between the user and device! Nothing works better really! Great for when carried in your pocket too! See videos online of people testing RF Safe cases with and RF meter. You either do or don't want to be exposed to it, if you don't, good options for protection are available.

NOW JUST IMAGINE: If some Galaxy flagship phone was barely legal like iPhone6??????? WOW,WOW WOW There would be such a noise, and saliva over Samsung, in the tech media.....even on the central news of all popular TV channels......every day....until they make ppl scared to even touch Samsung's phone. Right?????

Samsung phones are actually praised for their low SARs value.

Funny you should mention that. From Samsung's own website, they actually do have a version of the Galaxy S5 that is barely legal.​900R4&selNatCd=US&languageCode=EN Mind you, not all of the versions have this high of a rating. I also find it strange there is such a significant difference in SAR rating between different S5 versions. Regardless, several of their models run on the hairy edge as well.

Stop this guys... Let's say if your fav phone has high SAR rating...will it stop you from buying it??? I bet 95% will not care...i know it is bad....but don't make such a big issue of it...blackberries too have high SAR..but no one cares... If anyone who cares about this it should iphone users...not us...

iPhone 6 = Attention grabber, and for a title of a website like this you need attention grabbers to get more clicks.

Can you stop with this BS over and over again??? There will be even MORE clicks if the headline was : "Note 3/4 and even the other top smartphones have less SAR than iPhone 6" or: "iPhone6 is barely legal , for the health of the users"

Why is there an iPhone 6 image on the Galaxy S5's SAR? FAIL.

Does the SAR level go up the more you use the iPhone?

15. dimas

Posts: 3374; Member since: Jul 22, 2014

Yes it will. The longer you make calls, the more heat will be applied to your ear making you more susceptible to the radiation. But don't worry, iFans will ignore every scientific data as crap because hey, it's apple.

The Interphone, Hardell and the recently concluded CERENAT studies in France have all pointed towards a common risk to increased brain cancer. This is why the World Health Organization’s International Agency for Research on Cancer (IARC). WHO has classified electromagnetic frequency radiation emitted by cellphone, cell towers and wi-fi as category 2(B) or possibly carcinogenic. According to the Brain Tumor Foundation of Canada, brain tumors are the leading cause of cancer death in children under the age of 20, now surpassing acute lymphoblastic leukemia. They are the third leading cause of cancer death in young adults ages 20-39 Is it already happening?

Guess that could depend on if the iPhone users bottom puts more than 70 pounds of force on the phone. A bent iPhone can cause its microwave transmitter to utilize maximum output power; possibly exceeding safe RF Radiation levels whenever an iPhone’s antenna is either deformed or broken. Just more bad news for iPhone users stuck with a flimsily iPhone. On a more serious Note, the Galaxy Note series are much stronger than the iPhones and produce much lower SAR levels. iPhone isn’t the device for a Healthkit App yet, at least until Apple can start making the iPhone suitable for health conscious users! But to answer your question, yes the iPhones thermal levels of microwave radiation will contiune to increase SAR levels the longer you use your phone. Duration of exposure is a factor when simulated SAR values are calculated.

Of course. Your brains izombies, are already fried . Check out how is the SAR level of the older iphones, too. LOL That's the way they(Apple) incubate you.
