"After updating to iOS 18.6, my iPhone 14 Pro Max's battery drains very quickly. Even when left overnight and not in use at all, the battery level drops by 10%," user Minh Thanh reported.

"My iPhone is less stable than before. Especially when the battery level drops below 20%, the phone lags and gets very hot, and the keyboard also malfunctions, making it impossible to type normally," shared user Ngoc Ly about the problems with her iPhone 16 after updating to iOS 18.6.

According to observations by Dan Tri reporters, battery drain and overheating issues after updating to iOS 18.6 have appeared on many different devices, including the iPhone 16 series and older iPhone generations such as the iPhone 15, iPhone 14, etc.

"Some people say that after updating iOS, it will take about 2-3 days for the device to become more stable. However, it's been almost a week now, and my iPhone 15 Pro Max is still overheating even when not using heavy tasks," said Duc Thang about the iOS 18.6 bug.

According to Apple's support documentation, the iOS 18.6 operating system update will address dozens of critical security vulnerabilities on iPhones. Therefore, users are advised to install it immediately.
