What’s New in watchOS 26.4 Beta
Nine New Emoji Characters
watchOS 26.4 integrates Unicode Emoji 17.0, adding nine culturally relevant and expressive options. The complete new emoji set includes:
- 🎺 Trombone – Musical instrument representation for band and jazz contexts
- 🪙 Treasure chest – Gaming rewards and adventure-themed messaging
- 🥴 Distorted face – Embarrassed or woozy expression variant
- 🦍 Hairy creature – Bigfoot/Sasquatch for cryptid and outdoor references
- 🌪 Fight cloud – Comic-style action indicator for playful conflict
- 🍎 Apple core – Food waste awareness and sustainability symbol
- 🐋 Orca – Marine mammal alternative to generic whale emoji
- 💃 Ballet dancers – Performing arts and dance representation
- 🏔️ Landslide – Natural disaster and geology context
These additions align with Unicode Emoji 17.0 release specifications, ensuring cross-platform compatibility with iOS 26.4 and iPadOS 26.4. Users gain more precise communication tools for messaging and social media interactions directly from their wrist.
Siri AI Enhancements Expected
Apple’s AI-powered Siri overhaul may start its phased rollout with watchOS 26.4, though the company has not confirmed specific capabilities in beta 1. Sources indicate Siri improvements will arrive incrementally rather than as a single launch, allowing for testing and refinement across devices. This strategy mirrors Apple’s cautious approach to AI integration seen in previous iOS updates.
Developer testing suggests potential enhancements to voice recognition and contextual awareness, building on watchOS 26’s on-device language model improvements. However, Apple has not officially documented which Siri features will debut in 26.4 versus later updates.
Performance and Stability Improvements
watchOS 26.4 includes under-the-hood optimizations designed for upcoming Apple products expected to launch in spring 2026. While Apple hasn’t confirmed details, the beta’s timing suggests preparation for potential new Apple Watch models. The update builds on watchOS 26’s existing design improvements and hardware support for current models.
Developers testing the beta report general stability improvements typical of mid-cycle updates. These refinements prepare the platform for additional features expected throughout the watchOS 26 release cycle.
