In a surprising revelation, a former Apple employee has issued a cautionary message for iPhone users eager to upgrade to the new iOS 18 update. The warning comes as many users are looking to enhance their devices with the latest features, but concerns have emerged about potential compatibility issues and performance degradation on older models.
The ex-Apple engineer, who chose to remain anonymous, stated that users with iPhone models dating back to the iPhone 11 may experience significant slowdowns and battery drain after installing the update. “Apple tends to optimize its software for newer devices, and while iOS 18 promises exciting features, it may not run smoothly on older hardware,” the source explained.

Among the features touted in iOS 18 are enhanced privacy controls, advanced multitasking capabilities, and an upgraded user interface. While these upgrades are appealing, the former employee highlighted that users should consider the trade-offs. “Those with older iPhones could find themselves frustrated with lagging performance or diminished battery life.”
Apple has a long-standing reputation for offering regular software updates, but as technology progresses, older devices often struggle to keep pace. The warning serves as a reminder for users to assess their phone’s age and capabilities before committing to the new operating system.
In response to the concerns, Apple has not yet issued an official statement, but the company typically encourages users to back up their devices before any update and to check for specific compatibility requirements.

For those determined to upgrade, tech experts recommend performing a comprehensive backup and checking for any recent user feedback regarding the iOS 18 experience on older models. Additionally, users might consider delaying the update until any potential issues have been addressed by Apple.
As the iOS 18 rollout begins, consumers are advised to proceed with caution. The allure of new features may come at the cost of performance, particularly for those using devices that are no longer the latest in technology.
