Why iOS 18.5 Matters
iOS 18.5 (Beta 3, build ending in ‘J’) is a performance-focused update, addressing bugs and laying groundwork for iOS 19, expected later in 2025. While not a feature-heavy release, it introduces India-specific connectivity options and resolves critical issues, making it relevant for Airtel and Jio users. With a 1GB update size for Beta 2 to Beta 3 transitions and 6–7GB for others, it’s lightweight but impactful.
Key Updates in iOS 18.5
1. India-Specific Connectivity Enhancements
iOS 18.5 introduces two notable features for Indian iPhone users.

- Jio RCS Messaging: Prepares iPhones for Rich Communication Services, enhancing messaging with read receipts and media sharing, soon to be enabled.
- Modem Firmware Update: Upgraded to 1.60.02, improving network stability for WiFi, Bluetooth, and mobile data.
Why It Matters: Indian users with Airtel or Jio SIMs gain future-proof connectivity. Once activated, Airtel’s 5G standalone could offer 20% faster speeds (TRAI, 2025), while Jio’s RCS aligns with global messaging trends.
2. Performance and Stability Improvements
