We are witnessing a significant shift in mobile messaging platform requirements as WhatsApp officially discontinues support for older iPhone models, including the iPhone 6s, effective June 1, 2025. This comprehensive guide provides everything users need to know about this critical update and its implications for millions of iPhone users worldwide.
Understanding the WhatsApp iOS 15.1 Requirement
WhatsApp will only work on iPhones running iOS 15.1 or later starting June 1st, marking a decisive end to backward compatibility with older iPhone models. This requirement represents Meta’s strategic focus on enhanced security protocols and modern app functionality that older iOS versions simply cannot support.
The decision affects multiple iPhone generations, with iPhone 6s users facing particular challenges due to their device’s limited iOS upgrade path. While newer iPhone models can easily update to meet these requirements, legacy devices encounter technical barriers that prevent them from accessing the necessary iOS versions.

Complete List of Affected iPhone Models
Primary Models Losing WhatsApp Support
iPhone 5s, iPhone 6, and iPhone 6 Plus will be affected by WhatsApp dropping support for iOS versions older than 15.1. However, the situation is more nuanced for iPhone 6s users, as this model presents unique compatibility considerations.
Confirmed Incompatible Models:
- iPhone 5s (maximum iOS 12.5.7)
- iPhone 6 (maximum iOS 12.5.7)
- iPhone 6 Plus (maximum iOS 12.5.7)
Models Requiring Verification:
- iPhone 6s (upgradeable to iOS 15.7.2)
- iPhone 6s Plus (upgradeable to iOS 15.7.2)
- iPhone SE (1st generation, 2016)
iPhone 6s: The Critical Compatibility Question
The iPhone 6s occupies a unique position in this transition period. iPhone 6S can update to iOS 15.7.2, but not to a higher iOS version (16 and later), which places it in a gray area regarding WhatsApp compatibility.
Our analysis indicates that iPhone 6s users may retain WhatsApp functionality if their devices run iOS 15.7.2, as this version meets the minimum iOS 15.1 requirement. However, users should verify their current iOS version and update capabilities immediately.
Checking Your iPhone 6s Compatibility
To determine if your iPhone 6s will continue supporting WhatsApp:
- Navigate to Settings > General > About
- Verify your current iOS version
- Check for available software updates
- Ensure your device runs at least iOS 15.1

Technical Reasons Behind the Support Discontinuation of iPhone 6s
Security Enhancement Priorities
WhatsApp’s withdrawal of support aims to enhance user security amid rapidly advancing technology and escalating cyber threats. Modern security protocols require advanced iOS frameworks that older versions simply cannot provide.
Key Security Improvements Include:
- Enhanced end-to-end encryption protocols
- Advanced malware protection systems
- Improved privacy controls and data protection
- Modern authentication frameworks
- Updated cryptographic standards
Performance and Feature Optimization in iPhone 6s
Newer iOS versions provide essential APIs and development frameworks that enable WhatsApp’s latest features. Legacy iOS versions lack the technical infrastructure to support:
- Advanced message encryption algorithms
- High-quality media sharing capabilities
- Cloud backup integration improvements
- Voice and video calling enhancements
- Group chat functionality expansions
Timeline of Changes and Previous Delays
Originally, the change had been planned for May 5th. However, it seems the new cutoff date was pushed by a few weeks and landed on June 1st. This postponement provided users additional time to prepare for the transition, though many remained unaware of the impending changes.
Critical Timeline:
- December 2024: Initial announcement of iOS 15.1 requirement
- May 5, 2025: Original discontinuation date (postponed)
- June 1, 2025: Current implementation date
