When electronic equipment is used, it will often generate heat. This problem will affect many different electrical appliances, especially those with processing function. While this is easy to see on desktops and laptops, it is also common on mobile devices such as iPhones and iPads. Because mobile devices require a lightweight and compact design, mobile phones and tablets may get hot during use, such as for heavy processing tasks or wireless charging. The thermal management of processors and other chips must be carefully controlled. < / P > < p > in addition to causing discomfort to users when they are held, heat is also a big problem for electronic products. Heat can cause the metal structure in the circuit to malfunction, weaken or melt the welded connection at high temperatures, or worse. In order to improve the quality of life of users and maintain the equipment for a longer time, it is necessary to resist heat, either by adding additional cooling or by reducing the performance of heating elements. Since it’s not practical to add external cooling to the iPhone, this usually requires throttling, which may not be what device users want to see. < / P > < p > for security and availability, a balance must be struck, which means that there is a bias towards throttling enough availability rather than letting users hold it too hot. However, if the device can be determined that there is no risk to the user, it may run warmer and closer to its limits. Apple believes that the smart case equipped with MagSafe can make the iPhone run faster without causing harm to users due to overheating. As long as the presence of the case is detected, the iPhone can run at a higher temperature. In a patent granted by the U.S. patent and Trademark Office on Tuesday, the U.S. patent and Trademark Office issued a patent entitled “smart case for portable electronic devices” & quot; on Tuesday, apple proposed that it could help determine whether to control the processor by sensing whether it has used the shell. If the shell is detected, it can safely run faster and generate more heat without the risk of harming the user. < / P > < p > for this reason, apple recommends embedding a magnet in the case of the phone to create a magnetic field that can be detected by the iPhone or iPad via the Hall effect sensor. By detecting changes in the magnetic field in a specific configuration, this will tell the iPhone that a case is installed. If the case is detected, you can raise the iPhone’s operation from running at a lower temperature threshold or a lower temperature threshold to a second higher threshold, at least when the case is installed. Once the case is removed, a lower temperature threshold is applied, so there is a greater chance of throttling. < / P > < p > as part of the shell sensing function, apple suggests that it can include determining the direction of the magnetic field associated with a particular type of enclosure, which can then provide other benefits. For example, different shells may have different thermal properties, allowing the iPhone to run at different maximum temperatures. The use of NFC can also be used to detect the presence of a mobile phone case. The presence of an RFID tag in the case will generate a signal that can be read by the iPhone. < / P > < p > Apple submits a large number of patent applications every week, but although the existence of patents indicates the areas of interest for Apple’s R & D team, it does not guarantee that the concept will exist in future products or services.
