Apple (AAPL.O) announced on Saturday that it has uncovered a few vulnerabilities that may cause new iPhones to run hotter than planned, including a fault in the iOS 17 software that will be resolved in a future update.

Following complaints that the new phones are overheating, Apple has stated that the device may feel warmer in the first few days “after setting up or restoring the device due to increased background activity.”

“Another issue involves some recent updates to third-party apps that are causing them to overload the system,” Apple explained, adding that the company is working with app developers on remedies that are being handed out.

According to the business, the third-party apps triggering the problem include the game Asphalt 9, Meta’s (META.O) Instagram, and Uber. On September 27, Instagram fixed the problem with its app.

To address the iPhone’s temperature, the impending iOS 17 bug update will not affect performance.

According to the Cupertino, California-based corporation, the iPhone 15 Pro and Pro Max do not overheat due to the design, but rather the new titanium shells result in superior heat dissipation compared to previous stainless steel models.

Apple also stated that the problem poses no safety or harm risk and will have no long-term impact on the phone’s performance.
