iOS 26 Beta Hints at Larger Display for Apple Watch Ultra 3

Developer beta imagery confirms a jump to 422×514 pixels; potential additions include satellite messaging, blood pressure monitoring, LTPO3 refresh rates, 5G support, a next-generation SiP chip

Overview

  • The iOS 26 developer beta includes imagery indicating a 422×514-pixel display resolution, up from the Ultra 2’s 410×502
  • The unchanged case size is expected to house this larger screen through slimmer bezels rather than a bulkier frame
  • Rumors now coalesce around added satellite messaging capabilities for off-grid communication
  • Advanced health sensors like high blood pressure detection and an LTPO3 OLED panel for faster always-on refresh rates are anticipated
  • The Ultra 3 is also expected to feature 5G cellular support and a next-generation S10 or S11 system-in-package ahead of its reveal with the iPhone 17 event in September
