Magnetic cases have been with us practically since the arrival of smartphones, it is true that styles have changed and we could discuss at length about the aesthetic section, but the most interesting thing is to know how magnetic cases affect mobile phones . We may have heard many about them, but rarely have we known the truth.
There are currently several types of magnetic covers , the classic book covers , others that protect the back and front of the smartphone or also a combination of the book covers with a transparent shell. All of them work basically the same, with a series of small images that they manage to keep protects the mobile, but doubts are served in all of them.
The fake problems with magnetic sleeves
We will start by disproving all the myths that have been created around it, taking into account that in certain cases poorly designed covers and bad ones have a greater effect on our phones.
The battery does not discharge before
Something that we have been able to read and see in various places is that the smartphone battery suffers from using this type of case, something that is totally false. It is true that manufacturers recommend not to place magnets near the device and of course not with the battery, but the small magnet in these protective cases does not have enough capacity to cause the battery to be affected.
Magnetic covers do not break the screen easily
The magnets of the cases themselves are not capable of affecting the screen of mobile phones for the same reason as before, their capacities are very limited. However, magnets with a higher capacity can cause irreversible damage to the screen. If we want to prevent it, it will be better not to use these covers, although as we have mentioned it is not something that we should worry excessively.
Effects of magnetic cases on mobile
In addition to all the myths that we have known and which do not affect mobile phones to a great extent, there are other effects that go unnoticed, small than if they occur in most smartphones when using a magnetic case.
The compass of the mobile is decalibrated
The manufacturers themselves, such as Apple, have repeated the following in the case design instructions on many occasions: Apple recommends avoiding the use of magnets and metal components in the cases . This beyond the precaution that the manufacturers ask for have to do with problems in the software due to the compass.
Inside the phones there is a magnetic compass that helps the gyroscope and other sensors, through which we are offered an exact position when we open a map application or other services. In this case, the images, no matter how small, can vary the direction and confuse our mobile.
Can you use the magnetic sleeves?
Taking into account everything we have known, there is nothing that prevents us from using them, we only have to bear in mind that in certain cases the compass of the mobile could be affected, but we will be able to detect it ourselves. Regarding other situations, being careful nothing should happen. In case of doing so, we must take into account that the covers have passed the completed security controls and therefore an official magnetic covers of the brand of our mobile will always be safer.
However, if we do not have an irrevocable need for this type of covers, there will always be a silicone or gel alternative that suits us.
