The French agency that regulates radio frequencies, the ANFR, has notified Apple of its decision to ban iPhone 12 sales after tests showed the Specific Absorption Rate...
This title is so misleading. France hasn’t banned the device, and the radiation levels could likely be fixed with a software update. French officials have stated that they may prohibit sale and issue a recall IF Apple doesn’t respond to their request. The article says as much:
France's junior minister for the digital economy, Jean-Noël Barrot, told newspaper Le Parisien that a software update would be able to address the radiation issues linked to the iPhone 12. Apple has two weeks to respond to France's request, if it fails to do so, Barrot stated that he is prepared to issue a recall of the device, which went on sale in 2020.
Also, why the hell did it take French agencies 4 years to test this device? Even if Apple says they won’t update the phones and is forced to stop selling them, taking a 4 year old phone off the market won’t really hurt them in any way.
It would also affect already sold units. They are giving apple 2 weeks to come up with a software fix to remediate already sold units and if apple fails to comply, they will force apple to recall all the iPhone 12s still in use.
The French agency that regulates radio frequencies, the ANFR, has notified Apple of its decision to ban iPhone 12 sales after tests showed the Specific Absorption Rate (SAR) was above the allowed limit.
Followed by this quote:
The ANFR said it would verify that the iPhone 12 models were no longer being offered for sale in France starting today.
That sounds a lot like "banned" to me. Considering those two quotes, I don't think the article title is misleading. It sounds like they are banning sales effective immediately, and will force apple to conduct a recall if they can't retroactively fix the already sold units.
Your head might have gotten a little bit warmer compared to someone using a different phone while calling, especially if you live in an area with poor coverage.
If you or a loved one owned an iPhone 12 and have developed mesothelioma, you may be due compensation. Our lawyers are standing by to evaluate your claim so call today!
Probably not, but you could look into any recalls / software updates.
I haven't read the specifics, but I think if you store it in a bag or something and don't leave it in contact with your body too long, you should be fine. If it was more serious, there would be more of an announcement
Wait, they measure the wattage per kilogram of the device? Why does the weight of the device matter? Could they just increase the weight of the phone to pass the test?
It's not per kilogram of the device. It's a measure of absorption per kilogram of body mass of the person using the device.
A good way to think about it is: throw a small piece of meat into the microwave and let it absorb some microwaves. It gets warm. Now imagine a much larger piece of meat. It can absorb a lot more microwaves before it starts getting warm. The smaller the 'body mass', the less radiation it can absorb and dissipate before becoming damaged. So when it comes to mobile device radiation levels, they focus on the watts of radiation absorbed per kilogram of body mass.
and different parts of the body resonate at different frequencies...part of the reason ~2.4 GHz was picked for the common household microwave is water molecules resonate there (and other harmonically related frequencies too... it's why a lot of the unlicensed ISM stuff is allocated there: crappy atmospheric propagation). also the necessary magnetron and waveguide for that freq is conveniently sized for a kitchen appliance and not too complicated.
EDIT: see proper principle of operation in reply below
The agency noted that tests measuring radiation absorption rates at a distance of 5cms (1.98 inches) showed that the iPhone 12 was in compliance with the limit of 2.0 watts per kilogram.
But it also says that:
The ANFR said accredited labs had measured absorption of electromagnetic energy by the body at 5.74 watts per kilogram during tests simulating when the phone was being held in the hand or kept in a pocket, writes France 24. That's higher than the European standard absorption rate of 4.0 watts per kilogram.
That sounds like different test methodology was used for the test it is currently failing? There is a difference between "from 5 cm" vs "held in hand" or "kept in a pocket".
It makes it sound like the iPhone 12 was in compliance earlier, but is not in compliance now with different test methodology.
