Unlike iOS 18.4, iOS 18.5 is a minor update but includes some notable changes and additions that focus on quality-of-life improvements rather than flashy new features. Apple has concentrated on refining existing functionality while addressing critical security vulnerabilities.
Key Features and Updates
Pride Harmony Wallpaper: Celebrating Diversity
According to Apple, iOS 18.5 comes with five notable enhancements. One of them is the new Pride Harmony wallpaper available for iPhones and iPads, which is part of Apple’s 2025 Pride celebration. This vibrant new wallpaper adds a colorful option to personalize your device while supporting inclusivity.
Enhanced Screen Time Security for Parents
The most significant upgrade in iOS 18.5 revolves around parental controls. Apple has improved the security of Screen Time, as parents are now notified whenever their passcode is successfully entered on a child’s device. This makes it much more difficult for children to shoulder-surf or guess passwords to bypass restrictions.
What this means for families:
- Real-time notifications when kids attempt to override Screen Time limits
- Better protection against password guessing and observation
- Increased peace of mind for parents managing screen time
Mail App Refinements
Apple continues to polish the Mail app experience that was redesigned in iOS 18.2. iOS 18.5 adds a new toggle that lets you quickly disable the new contact photos design in the Mail app, giving users more control over their email interface appearance.
Mail app improvements include:
- Option to turn off contact photos in email lists
- Better customization for traditional email viewing preferences
- Continued refinement of the categorization system
