Apple has officially acknowledged reports from some users of its latest iPhone 15 Pro and Pro Max models experiencing overheating issues. The company has assured users that it’s actively developing a software update to address this problem. Additionally, Apple disclosed that specific apps were contributing to the excessive heat, and they are collaborating with developers to enhance their performance.
Initial complaints about overheating emerged from users on Apple’s community forum, who voiced concerns that their new iPhones were becoming uncomfortably hot to handle. Some reported that their devices reached temperatures exceeding 43 degrees Celsius (110 degrees Fahrenheit), adversely impacting battery life and overall performance. A few even mentioned discomfort due to the heat emitted by the phones.
Software bug and app optimization
Apple clarified that during the initial setup or device restoration, users might notice their phones feeling warmer due to increased background activity. However, the company acknowledged that a software bug was present in its iOS 17 operating system, which powers the iPhone 15 series, and was causing overheating. Apple reassured users that there were no safety concerns associated with the iPhone 15 during this time, and it wouldn’t affect the device’s long-term performance. A fix for this bug was actively in development.
Furthermore, Apple identified certain apps, including Instagram, Uber, and Asphalt 9, as culprits that were overloading the system and causing excessive heat. Instagram had already made modifications to its app to prevent this overheating issue, while Uber and other apps were working on updates to rectify the problem. Apple advised users to regularly update their apps to ensure optimal device performance.
Thermal system design
According to Apple analyst Ming-Chi Kuo, the overheating problem likely stemmed from compromises made in the iPhone’s thermal system design to maintain its lightweight form. These compromises involve a reduced heat dissipation area and the integration of a new titanium frame, which impacts thermal efficiency.
Operating temperature range
Apple also reminded users to operate their devices within the recommended temperature range of 0 to 35 degrees Celsius (32 to 95 degrees Fahrenheit) and to avoid exposing them to direct sunlight or extreme heat, such as leaving them in a car on a hot day. The company emphasized that certain activities, such as extended use of GPS tracking or navigation, intensive gaming, or augmented-reality apps, in hot conditions or direct sunlight could lead to overheating issues.
