Shortly after this update was released, many users reported experiencing various problems after upgrading their devices to iOS 26.

On online forums and groups sharing iPhone usage experiences, many users have reported that iPhones become hotter and drain battery faster after updating to iOS 26. This issue has been observed on many older devices such as the iPhone 12, iPhone 14, and iPhone 15.

This is a common problem that occurs whenever Apple releases a completely new version of its operating system.

Overheating also affects device performance. Some users have reported that their iPhones suddenly experience lag and freezing even when performing basic tasks like browsing the web or using Facebook.

"After using iOS 26 for over a day, I've noticed my iPhone 15 Pro Max is less stable. Notably, the screen is even stuttering when viewing images on Facebook," commented user Minh Tuệ.

Other issues have also been reported, such as app icons not displaying, wireless CarPlay connection errors, and widgets disappearing when switching to transparent mode, etc.

"The CarPlay interface on iOS 26 is quite vibrant. However, it seems that the connectivity of this version lacks stability. The device keeps disconnecting from the car, something that never happened before," shared user Anh Tú about his iPhone 14 Plus after updating to iOS 26.

Meanwhile, some users have reported that the new Liquid Glass interface on iOS 26 is relatively difficult to use.

"The interface design on iOS 26 is quite new and interesting for the first few hours of use. However, after using it for a while, this interface becomes cluttered and difficult to get used to compared to iOS 18. I'm looking for a way to revert to the old version," said user Thanh Trung.

Alongside iOS 26, Apple also released the iOS 18.7 update. In its operating system description, the company stated that this version provides important bug fixes and security updates, recommended for all users.

If users don't want to update to iOS 26 yet, they can choose to upgrade to this operating system version to install the necessary security patches for their device.
