iPhone has a fever of unknown cause, what should I do?-Why can't I ask the iPhone now?
One of the charms and strengths of the iPhone is that you can understand how to use it without reading the manual. However, even if you think you know it, there must be something you don't understand correctly. In this corner, we will explain in an easy-to-understand manner "why the iPhone can't be asked now". This time, we will answer the question "What should I do if my iPhone has a fever of unknown cause?"
＊＊＊
The iPhone is both a smartphone and a mobile phone, but it is also a small computer. Its performance is equivalent to that of a high-performance workstation of a decade ago, and it is a computer with excellent computing performance and drawing ability. It has such high processing power that it surpasses even the performance of personal computers released several years ago.
The central processing unit is the CPU. In the case of the iPhone, it is sometimes called "SoC (System on a Chip)" because it integrates a chip dedicated to drawing processing (GPU), etc., but the structure in which the part corresponding to the brain in a human being takes charge of arithmetic processing is general. It's no different than a regular computer.
The CPU heats up as it does its work. However, once processing involving a high load, such as complicated calculations, is completed, the heat will subside, and the heat will gradually decrease. In the case of the iPhone, heat is released to the main body structure (frame) and dissipated throughout the body, so placing it in a well-ventilated place or on a metal desk with high thermal conductivity will shorten the time. the heat will go down. Since the case prevents heat dissipation, it is not preferable in terms of heat countermeasures.
However, even if you wait for a while, the fever may not subside, and it may even get hotter. It occurs when a program (application or system) falls into a loop processing for some reason in a so-called "runaway" state. Since runaway involves full CPU operation, heat dissipation cannot keep up with heat generation, and the iPhone gets hot. At the same time, power is also consumed, so it is possible to estimate the presence or absence of a runaway program at the pace at which the battery is depleted.
One way to deal with this is to end the suspicious app on the task management screen. If you can't identify which app is causing the issue, you can try restarting the system by pressing and holding the sleep button. Now you can stop the runaway program.
If your iPhone is hotter than usual and the battery is draining very quickly, suspect a "runaway" . You can stop it by closing the suspicious apps or restarting your system |
