Apple explains that the iPhone 15 Pro's abnormal heat generation problem is caused by software, not hardware, and promises to release software updates to improve it.



Apple has acknowledged the abnormal heating issue reported with the iPhone 15 Pro and iPhone 15 Pro Max, and issued a statement that it is caused by software, not hardware. Apple promises to fix the overheating issue with an iOS 17 software update.

Multiple users have reported an issue with the iPhone 15 series released on September 22, 2023, where the device heats up abnormally when charging quickly or when used for long periods of time. In particular, there were many reports of abnormal heat generation with the iPhone 15 Pro and iPhone 15 Pro Max, so it was initially pointed out that the A17 Pro may be the cause of the abnormal heat generation.

However, Ming-Chi Kuo, a prominent Apple-related analyst, said, ``According to my research, the overheating issue of the iPhone 15 Pro series has nothing to do with TSMC's advanced 3nm process, which is responsible for manufacturing the A17 Pro. This is because a compromise was made to the thermal design in order to reduce weight by using a titanium frame, reducing the heat dissipation area and worsening thermal efficiency.

Regarding this abnormal heating issue, Apple issued a statement to David Phelan of Forbes saying, ``The cause of the overheating is software, not hardware, and it will be resolved soon with a software update for iOS 17.'' Did.

Apple says, 'We've identified several conditions that can cause your iPhone to run hotter than expected. For the first few days after setting up or restoring your device, increased background activity may cause your device to run hotter than expected. 'In some cases, the device may feel hot,' he said, adding that the increased activity running in the background, especially when restoring the device from a backup, causes abnormal heat generation. In addition, Apple also explains on its official support page that the device heats up when restoring from a backup .

When you upgrade your iPhone's iOS to a major version such as iOS 17, your device may run slowly and run warmer than usual for the first few hours or even days after the upgrade. Apple claims that this heat generation is more excessive than usual. However, some people claim that their iPhone 15 Pro continues to overheat hours or even days after upgrading the OS.



Apple also said, ``Another problem is that the latest updates to third-party apps can overload the system. We are working with these app developers to deploy a fix.'' It explains that third-party app updates are overloading the system. According to Forbes, third-party apps that are causing abnormal fevers include popular apps with millions of users, such as Instagram and Uber. One of the apps that causes abnormal heat generation is the racing game app '

Asphalt 9: Legends ,' and apps that output detailed graphics like this app also seem to cause abnormal heat generation. According to Forbes, Instagram fixed the problem with a software update on Wednesday, September 25, 2023.

In addition, Apple also said, ``We have also discovered a bug in iOS 17 that affects some users, and we plan to fix this in a software update.'' It has been pointed out that Apple may reduce the performance of the A17 Pro in order to suppress abnormal heat generation, but Forbes said, ``In order to solve the iPhone abnormal heat generation problem with this software update, we will not reduce the performance of the CPU. There doesn't seem to be any.''

In other words, according to Apple, there are three causes of abnormal heat generation:

・Restore your device from backup
・Third-party apps that behave incorrectly
・iOS 17 bugs



In addition, some iPhone users claim that not only the iPhone 15 Pro but also the iPhone 15 and iPhone 15 Plus generate abnormal heat. In fact, according to DxOMark, a smartphone benchmark website, it has been confirmed that not only the iPhone 15 Pro but also the iPhone 15 generates abnormal heat when charging.



It has also been pointed out that the abnormal heat generation during charging may be caused by the charger rather than the iPhone. However, many existing USB-C power adapters support USB Power Delivery (USB PD), and USB PD automatically recognizes the current and voltage information required to charge the device and supplies power. Apple-related media iDownloadBlog points out that it is unlikely that the charger is the cause.

In addition, the iPhone has a function that detects the temperature of the device, displays a temperature warning message if the temperature exceeds the allowable limit, and becomes unusable until the temperature falls. Therefore, there is no need to worry about your iPhone malfunctioning due to abnormal heat generation.



However, Apple's software update seems to only be able to resolve the abnormal heat generation problem of the iPhone 15 Pro, and the cause of the abnormal heat generation of the iPhone 15 and iPhone 15 Plus remains unknown.
