Apple is working on a software fix following reports that some of its new iPhone 15 models are overheating.
The company told CNN the current overheating issues are not a safety risk and will not affect the long-term performance of impacted iPhone models. It also emphasized that iPhones have internal protections for components to help regulate the temperature if it gets too high.
Apple also told CNN there are several circumstances that are causing its next-generation lineup to heat up. User complaints started to circulate after the latest iPhones hit stores on September 22.
"We have identified a few conditions which can cause iPhone to run warmer than expected," Apple told CNN in a statement.
To start, overheating can occur with some recently updated third-party apps, causing them to "overload the system," the company said. Those apps include Instagram, Uber and arcade racing game Asphalt 9.
"We're working with these app developers on fixes that are in the process of rolling out," Apple said in a statement.
It also said it discovered a bug in iOS 17 impacting some users, and plans to roll out a software update to address the issue. It did not comment on when the fix will be made available.
In addition, Apple said the device may feel warmer during the first few days after setting up or restoring the device because of "increased background activity."
Apple's support page warns users that a device can get hotter when restoring it from a backup, using graphic-intensive apps, streaming high-quality video, and charging it wirelessly.
"These conditions are normal, and your device will return to a regular temperature when the process is complete or when you finish your activity," the company states on the website. "If your device doesn't display a temperature warning, you can keep using your device."
The news comes as demand for the iPhone 15 appears strong. Leading up to launch day, analysts at firms such as Wedbush Securities reported iPhone 15 pre-orders tracking better than originally expected, with a heavy demand on its premium iPhone 15 Pro offerings, especially the Pro Max. Delivery and shipment times have moved to late October through mid-November for various Pro models.
The new iPhones come as Apple reported in August that sales fell for the third consecutive quarter. iPhone revenue came in at $39.7 billion for the third quarter, marking an approximately 2% year-over-year decline, as users update their devices less often.
But according to Wedbush estimates, about 250 million iPhones have not been upgraded in more than four years. Advancements made to the processor, camera and charging system, along with discounts from mobile carriers, could be more than enough reason for users to finally upgrade this year.
The iPhone 15 Pro starts at $1,099, and the iPhone 15 Pro Max starts at $1,199. Apple's entry-level iPhones, the iPhone 15 and iPhone 15 Plus, cost $799 and $899, respectively.
