Faster and More Efficient S11 Chip
The Apple Watch Series 11 is expected to debut with the all-new S11 chip, designed to deliver better performance and improved power efficiency. Apple has reportedly engineered the S11 with a more compact layout, allowing extra space for larger batteries or additional internal components. The result could be faster processing, longer battery life, and enhanced support for advanced health and fitness features.
Updated Modem with 5G RedCap Support
In a notable connectivity upgrade, Apple may equip the Series 11 with new modem technology from MediaTek that supports 5G RedCap. Unlike full-speed 5G, RedCap is optimized for wearable devices, balancing speed, battery efficiency, and cost-effectiveness. This addition would improve real-time syncing, cloud-based app functionality, and streaming capabilities without significantly draining battery power.
Blood Pressure Monitoring and Hypertension Alerts
One of the most anticipated potential health features for the Apple Watch Series 11 is blood pressure monitoring. While exact systolic and diastolic readings like those from medical-grade cuffs are unlikely, Apple is reportedly working on a hypertension detection system.
This system would monitor blood pressure trends over time and alert users if elevated levels are consistently detected. Hypertension is a key risk factor for conditions like heart disease and stroke, making early alerts valuable for proactive healthcare. If the technology is ready in time, it could become one of the most significant health upgrades to the Apple Watch platform in years.
watchOS 26: New Features and Redesign
The Apple Watch Series 11 will launch with watchOS 26, which is currently in beta testing. This software update will introduce a range of new capabilities:
-
Workout Buddy – An AI-powered personal training companion that uses text-to-speech technology, trained on real Apple Fitness+ trainer voices. Designed to motivate and guide workouts, Workout Buddy requires a paired iPhone running Apple Intelligence.
-
Liquid Glass Design – A refreshed interface matching the new iOS 26 aesthetic, offering a sleek and modern visual style.
-
Updated Smart Stack – Improved widget organization for faster access to key information.
-
Revamped Control Center – Streamlined layout for more intuitive navigation.
-
New Gestures – Expanded gesture support for easier watch control without touching the screen.
Sleep Score Feature in Development
Although Apple Watch already provides sleep tracking data such as REM, Core, and Deep sleep phases, as well as time in bed and time awake, there is still no sleep score metric. This rumored feature would analyze multiple health data points to estimate daily performance potential based on sleep quality. While there’s no sign of this function in current watchOS 26 betas, it could be introduced exclusively on the Series 11.
10th Anniversary of the Apple Watch
2025 marks a decade since the original Apple Watch debuted. Earlier rumors suggested Apple might celebrate with a special anniversary edition featuring a redesigned casing and a magnetic band attachment system. However, with no clear evidence of these changes in leaks so far, the Series 11 may focus on evolutionary rather than revolutionary updates. Apple could still commemorate the milestone through marketing, special packaging, or limited-edition models.
Blood Oxygen Monitoring Remains Limited
Due to ongoing legal and regulatory issues, blood oxygen monitoring remains unavailable on Apple Watch models sold in the United States. Current reports indicate that this restriction will continue with the Series 11, meaning users in affected regions will not see this feature return for now.
