One of the most widespread and ancient recommendations that exist in the field of electronic devices is to not buy the first runs of the same. Despite numerous quality controls that are subjected sometimes they carry small defects to reach the stores that are corrected by the responsible in later fabrications. One recommendation, of course, very difficult to carry out when it comes to smartphones.

Commented on the review of the problems with the batteries of the Samsung Galaxy Note 7 that few manufacturers can boast not to lay any manufacturing problem, and that is precisely what may be happening right now with the iPhone in July. Some users report the appearance of a small whistle when the processor is running at maximum, and some believe to have found the explanation for the problem.

Some explanations to dismiss

Yet the problem that exists with the Samsung Galaxy Note 7 had not missed that automatically put the focus on Apple, accusing them of certain errors when building the new iPhone 7 which may have led to this whistle. Accusations thrown away because, as some media check, the whistle also heard in previous iPhone models , although with less intensity.

That it is a problem that takes some time inside terminals Apple rule, first, it is due to the absence of the headphone jack. The clearance of this in the iPhone 7 would have occupied a larger motor, one of the first mentioned when seeking explanation for this whistle.

The other explanation, not as discardable, is concerned problem of sealing the terminal itself . A possible exchange of hot air to the outside, hence the appearance of the whistle when the A10 processor runs at maximum power, which would be caused by a leak in the body unibody iPhone. Since we are talking about, for the first time, a completely waterproof iPhone thanks to the IP67 certification, should start to discard this explanation. Although there are defective devices in all families.

Coils, or the coil whine

Among many possible explanations for the whistle that appears to be random, and not be present on all iPhone 7 sold so far, he has appeared in matching various electronics experts. The whistle could be caused by a coil plate iPhone and appear more significantly, making it easier to hear, with the processor to develop their full potential.

This noise, confirmed that it is this coil whine or sound from a coil, would be of electrical origin and appears to be, once plumbed the electronics market, quite common. The effect, which is known as coil whine (or lament the coil), is called magnetostriction and as we say, is very common. It seems to occur with some regularity in the most advanced graphics cards for PCs and consoles, but also in other high – performance devices.

The coils are subjected to electric fields and magnetic fields are generated. The same field forces that can eventually produce the coil physically vibrate, producing the whistle that sometimes it is not as weak as would be desirable. The sound increase may occur, in fact, if used in the terminal resonant frequencies of the coil itself, as the combination between the causes is amplified.

As discussed the most knowledgeable in physics and electronics, increased stress on electronic circuitries makes them more prone to noise, and hence the iPhone 7, when subjected processor very complex and demanding tasks, reach produce this sound that some users are detecting and reporting.

Possible solutions

For now Apple remains silent about this matter with the hiss of its iPhone in July, possibly because they are still in the process of detection and diagnosis, but as sources close cite the Californian company about a possible replacement without charge if the customer requests. This automatically entail the assumption by the company of a manufacturing error, a flaw in some terminals.

Other sources say that if it is finally a problem with the vibration of the coils, Apple could fix it with a software patch for the next version of iOS 10, which should not be delayed to correct small defects which they are found in the operating system. With this patch, Apple could reduce the maximum power of your processor and avoid stress to their devices, reducing or eliminating the whistle.

To wait because the manufacturer has not yet ruled on the matter and complaints, for now, they are quite isolated. Although it is only necessary to appear in the media for all users begin to perceive the whistle and claim your refund in these cases. We’ll see how Apple saves this possible claim at hand. As for your safety, do not fear, electronic components sound. We have already seen.
