SAR levels

A few words about SAR. Phone has body 0.62W/kg and head 0.75W/kg SAR levels.
Info from Carl (admin OPO forum) http://forums.oneplus.net/threads/oneplus-one-what-about-s-a-r-levels.821/#post-289699

I had no idea what this was so I googled it.
WHAT IS SAR AND WHAT IS ALL THE FUSS ABOUT?
SAR (specific absorption rate) is an indication of the amount of radiation that is absorbed into a head whilst using a cellular phone, the higher the SAR rating the more radiation that is absorbed into the head.
SPECIFIC ABSORPTION RATE (SAR)
A SAR value is a measure of the maximum energy absorbed by a unit of mass of exposed tissue of a person using a mobile phone, over a given time or more simply the power absorbed per unit mass. SAR values are usually expressed in units of watts per kilogram (W/kg) in either 1g or 10g of tissue.
EXPOSURE LIMITS
In Europe, the European Council Recommendation 519/1999/EC for exposure guidelines has adopted the recommendations made by the International Commission on Non-Ionising Radiation Protection (ICNIRP Guidelines 1998). In the US, the FCC, Federal Communications Commission, sets the radio frequency safety guidelines that all phones must meet before being sold in the US. Current reference standards and limits (status January 2001).

I have no idea if this is good or bad? how is it compared to other phones?

I think it's good.

As reference, I looked up the SAR of several phones... Samsung Galaxy SIII i535 (CDMA. VZW) had an overall rating of 1.29 US / 0.88 EU. Note the US and EU measure them differently. The US legal limit is 2.0. The source did not differentiate 'head' or 'body". source: http://sarshield.com/radiation-chart/
They're selling a radiation shield to help prevent exposure and it benefits them to provide lots of information - so take this with a grain of salt. It is very difficult to find comprehensive lists because the manufacturers would rather not have to publish this information. Lots of issues related to radiation exposure potentially causing brain cancer. Kind of like the cigarette manufacturers - smoking didn't cause cancer, no need to worry, nothing to see here, move along.

S7 edge Italian TIM version ok ?

Hi.. So the best price I can find easily in europe is to buy the S7 Edge "Italia Tim" . Its on Amazon it
It says its the G935 but I guess firmware is for Italy. My concern is.. I'm American living in Greece now.. but want to return to USA and have Samsung pay work etc. and I don't know if updates will come from TIM ?? Supposed the phone only has like 3 apps put on by TIM and its unlocked. Is it worth it to pay a little more and get it from the UK Version?

Either you buy this one or the non-branded one, you wont have any problem (Theoratically). I don't know tho about the SPay if it is going to work in america. I recommend you to flash a non-branded os once you get the phone. If you are going to use at&t or t-mobile, you are not going to have any problem with the signal

Thanks for the answer. Just to clarify... this "tim" version.. I can flash it correctly? And if so.. this takes away updates if they were from Tim? Far as I understand this version is unlocked and can be used anywhere (europe first etc)

Honor 8 is the Highest SAR value rated phone

Seems that the Electromagnetic radiation emitted by Huawei Honor 8 is 1.5 watt per kg, which is the highest among all smartphones currently.
The rank of high electromagnetic radiation with some other mobiles (from major to minor) are listed below:
1) Huawei Honor 8 is (1.5 watt per kg)
2) iPhone 7 (1.38 watts per kg)
3) Huawei Honor 5C (1.14 watts per kg)
4) Huawei Honor 7 (1.13 watts per kg)
5) iPhone 6S (0.87 watts per kg)
The list with the smartphones that emit less radiation (from minor to major) is the following one:
1. Samsung Galaxy S7 Edge (0.264)
2. Lenovo Moto Z (0.304)
3. OnePlus 3 (0.394)
4. Samsung Galaxy S7 (0.406)
5. Huawei Honor 5X (0.560)
From the list, we can see that Honor 8 is having High SAR rate and honor 5X having Low SAR rate in Honor brands.
Hope so this information will be useful before buying your mobile.
High SAR rate is due that the signal receiving capacity of the device is High.

That's a meaningless set of statistics and the article doesn't give any indication of the methodology.
1) A mobile phone is an RF transmitter, running within a given set of statutorily fixed limits. An iPhone 7 will have broadly the same transmit power as any other. The biggest factor will be network conditions, as the phone ramps down it's transmit power as low as it can, so the worse the path to the cell tower, the more power the phone will use.
2) Watts/kg is a good metric for categorising cyclists, useless for mobile phones, unless you have some very peculiar requirements.
The article linked appears to be discussing the long-discredited health effects of mobile phones. Even if there were anything in it, the type of modern mobile phone would be irrelevant - the difference in transmission paths into the head would be in the order of millimeters and the actual transmission power would be almost identical.

Does it mean that if the path to the cell tower is worst, then Honor 8 emits more radiation than others?
And if there is No use with the SAR value, why it is regulated ? Then for what purpose that information is used for?

I pretty much use Google Hangouts over WiFi, I only take incoming text and calls over T-Mo WiFi, which of course isn't available on the Honor 8 yet.

Is this bad then?

It's how much radiation energy get absorbs into your cranium when you talk on the phone. Or potentially to your balls while the phone is in your pocket.

View attachment 3974626
It depends from the connection type and band used.
In my country we have LTE band 7, according to the doc it's just 0.11
Anyway, it's the best to keep the phone as far from your body(especially important organs) as possible.

Those numbers aren't bad at all for B2, B4, or B12. All of which T-Mobile use. If you're on AT&T, your brain might melt a little bit. B5 and B17 numbers are really high!

In India JIO uses Band 5.
And I think Indian Honor 6 variant supports only Band 5 sadly.

i cant say that's wrong but i can say since i receive the phone yesterday i cant feel its a value phone with the price i payed !.. even the finger touch into the back feels cheap !..
i am disappointed !

Wrong thread. OP has nothing to do how you feel about your phone.
Sent from my FRD-L04 using Tapatalk

This is pretty meaningless:
1. Unless you hold your phone exactly like the official test setup is, your result will be wildly different.
2. The highest level allowed is an order of magnitude than the lowest level thought to pose any possible risk.

Just FYI
Quote
______
United States: the FCC requires that phones sold have a SAR level at or below 1.6 watts per kilogram (W/kg) taken over the volume containing a mass of 1 gram of tissue that is absorbing the most signal.
European Union: CENELEC specify SAR limits within the EU, following IEC standards. For mobile phones, and other such hand-held devices, the SAR limit is 2 W/kg averaged over the 10 g of tissue absorbing the most signal (IEC 62209-1).
India: switched from the EU limits to the US limits for mobile handsets in 2012. Unlike the US, India will not rely solely on SAR measurements provided by manufacturers; random compliance tests are done by a government-run Telecommunication Engineering Center (TEC) SAR Laboratory on handsets and 10% of towers. All handsets must have a hands free mode.[4]
SAR values are heavily dependent on the size of the averaging volume. Without information about the averaging volume used, comparisons between different measurements cannot be made. Thus, the European 10-gram ratings should be compared among themselves, and the American 1-gram ratings should only be compared among themselves.
Unquote

So it looks like the Honor 8 SAR ratings are within the limits prescribed in various parts of the world. Equally importantly, as noted above just quoting a SAR number by itself without reference to the method used for measuring it is quite meaningless for comparing one SAR rating with another!

I guess if use a very heavy case, I can reduce the SAR to a much lower level, or should the weight of the case not be counted?

SAR HEAD Value

Hey,
Comments on the fact this phone has a SAR value of 1.75? which is high
thinking of selling it soon.

That' s true that Mi a1 is one with the highest SAR value.
Anyway, take a look to this:

Great article.
Dispite the unknown about what radiation doest to us, especially phone's, it's definily better to have a lower sar value phone..

I agree with you, it is bad to unknown the effects of radiation... What if scientists discover that a 1.0 value is deadly and will cause tumor 100%? We are all f***ed

I assume you are talking about India. For 601KL model SAR value is 0.549 W/kg (Head) and 1.340 W/kg (Body) which is below the limit of 1.6 W/kg mandated by Department of Telecom, GoI. So i dont know where you got the info that it is high.
Regarding slow/fast motion updates - No idea.

I mean it's high compared to it's competitor phones like redimi note 5 pro and many other smart phones.why is it so?wifi when switched on is not connecting quickly.it must be fixed
Thanks
