蘋果 iOS 26 採用率穩定 緩解下滑疑慮

• iOS 26 released September 2025 (based on 150-day measurement window from February 12, 2026)
• Adoption metrics measured via App Store transacting devices, providing real-world usage data rather than theoretical install base
• iOS 26.3 released in early February 2026, adding native Android data migration tool and EU-specific Notification Forwarding for wearables
• Measurement methodology: App Store metrics capture only devices that have transacted with the store, potentially excluding inactive devices and creating a selection bias toward engaged users
• Distribution breakdown across all active iPhones: 66% iOS 26, 24% iOS 18, 10% earlier versions
• Distribution breakdown across all active iPads: 57% iPadOS 26, 26% iPadOS 18, 17% earlier versions

iOS 26's steady adoption trajectory suggests Apple's iterative approach to OS development—emphasizing stability and incremental improvements over transformative features—resonates with users despite slower initial uptake. The year-over-year iPad adoption gains indicate the company's tablet ecosystem is maturing with stronger upgrade incentives. If adoption continues tracking iOS 18's pattern, iOS 26 could reach 70%+ across all devices by mid-2026, maintaining Apple's historical consistency. The introduction of Android migration tools in iOS 26.3 signals Apple's competitive focus on cross-platform switching costs, potentially influencing long-term ecosystem lock-in metrics. Slower feature-driven adoption may pressure Apple to emphasize security, privacy, and AI capabilities more aggressively in iOS 27 to stimulate upgrade cycles.
