Apple's latest iPhone models, the iPhone 15 series, have been in the hands of users for just over a week, and some have reported issues with their devices getting unusually hot. Apple has responded to these concerns and shed light on the situation.
According to Apple, several factors can contribute to iPhones running warmer than expected. During the initial setup or when restoring a device, there can be increased background activity as the phone redownloads apps, photos, and music from a previous device. This extra workload can lead to elevated temperatures.
In addition to this, Apple acknowledged a bug in iOS 17 that is affecting some users. This issue will be addressed in an upcoming software update. Another problem involves recent updates to third-party apps, which can overload the system and lead to overheating. Apple is actively collaborating with app developers to implement fixes that are currently being rolled out.
It's important to note that not all iPhone users have encountered this problem, and devices tested for review purposes didn't exhibit overheating issues. This suggests that the problem may be intermittent.
Some speculation has arisen that the overheating could be linked to the new titanium material used in the iPhone 15 Pro and iPhone 15 Pro Max. However, Apple dismissed this notion, emphasizing that the titanium design, combined with an aluminum substructure, is effective at dissipating heat. Overheating is not attributed to the design of these new models.
Certain apps have also been identified as culprits in raising the iPhone's temperature. Apps like Instagram, Uber, and Asphalt 9 can cause the device to get hot. Apple is actively collaborating with these app developers to mitigate the issue and is investigating whether other apps are contributing to overheating. Instagram, for example, released an update on September 27 to address this problem.
It's worth noting that Apple's forthcoming iOS 17.1 update, currently in beta testing, will address the temperature issue without compromising device performance.
Apple also clarified that larger USB-C power adapters, exceeding 20W, can temporarily raise the iPhone's temperature. However, this doesn't pose a safety risk, as iPhones have built-in protections to prevent overheating. The device regulates its power consumption when using higher-wattage chargers compliant with the USB-C PD (Power Delivery) standard.
