Introduction
The Apple Watch Series 11 is the latest in the Apple Watch series, building on the solid foundation of the Apple Watch Series 10 with a bunch of nice upgrades. Apple continues to refine its iconic smartwatch, balancing style, performance and health tracking. With better battery life, new health features and more durability, the Series 11 is a good upgrade for anyone considering to upgrade. In this post we’ll break down the features, compare Series 11 to previous models and help you decide if upgrading to the new watch series is worth it.
Apple Watch Series 11 vs Series 10: What’s New?
At first glance the Apple Watch Series 11 looks almost the same as the Series 10, but there are some subtle differences. When comparing both the series, they have the same 9.7mm slim design, 42mm and 46mm case sizes, and Apple Watch Series 10 strap compatibility. But the Series 11 builds on last year’s series, with Apple focusing on sustainability, durability and battery life.
The Series 11 uses 100% recycled titanium for the premium models and 40% recycled display glass, and the battery is 100% recycled cobalt. The Hermès edition is available in silver titanium. For those who want a modern look, the Series 11 is available in space gray, rose gold and jet black, each looking sleek and stylish. The space gray aluminum is one of the options for the aluminum models which use Ion-X glass for durability. Titanium models use sapphire crystal for even more scratch resistance. Aluminum models are light and durable, titanium models are premium and protected.
Apple’s commitment to sustainability and design innovation is evident in the Series 11, as the brand continues to combine technology with eco-friendly materials.
Battery Life and Performance
Both watches use the same S10 chip, which is the key to their performance and battery life. When comparing battery life, Apple claims up to 24 hours (and 38 hours in Low Power Mode) for the Series 11, compared to 18 hours on the Series 10. In real world testing, most users find that actual battery life during normal use is often more than the official ratings, with typical usage delivering between 27–32 hours per charge.
Charging has also improved, with both faster charging and fast charging now available. You can get 80% in 30 minutes, and a 5-minute charge gives you enough power for a full night’s sleep tracking. A 15-minute fast charge gives you up to 8 hours of use, perfect for busy schedules.
These battery and charging improvements make the Series 11 feel fresh especially for those upgrading from older models.
Connectivity and Smart Features
The biggest upgrade is 5G Reduced Capacity (5G RedCap) on the Apple Watch Series 11 Cellular models, which provides better cellular connectivity for faster downloads, more stable connections and better efficiency when using the watch without your iPhone. This is great for workouts, quick outings and everyday use by maintaining a connection while consuming less power.
This year’s model, the new Apple Watch Series 11 also features second generation Ultra Wideband for advanced location tracking and seamless device integration.
Both models have Bluetooth 5.3, Wi-Fi 4 and WatchOS 26 which introduces new features like Sleep Score, hypertension notifications, the returning Blood Oxygen app and the Workout Buddy AI coach. The health app now consolidates health data, integrating these new features for a more comprehensive and user-friendly health monitoring experience.
Display and Durability
Both watches have Apple’s beautiful LTPO 3 wide angle OLED Retina display with up to 2,000 nits of brightness for outdoor use, so you can see it from any angle in bright environments. The new Series 11’s Ion-X glass and sapphire crystal options are more scratch resistant, with the Series 11 using scratch resistant glass for extra protection and durability in daily wear. The Titanium Series 11 models are lighter, slimmer and now fully made from recycled materials without losing the premium feel Apple is known for. You can also use the wrist flick gesture to interact with the watch, such as dismissing notifications or going back to the watch face, without touching the screen.
Health and Fitness
The Apple Watch Series 11 takes health and fitness to the next level, making it a great companion for anyone focused on wellness. With advanced heart rate monitoring and ECG, you can keep an eye on your cardiovascular health. The built-in blood oxygen monitoring gives you insights into your respiratory wellness, while the enhanced sleep tracking now includes sleep apnea notifications for early detection of potential issues. One of the new features is hypertension notifications which alert you if signs of high blood pressure are detected, so you can stay on top of your health. The new Sleep Score gives you a clear, easy to understand grade for your nightly rest, breaking down factors like sleep duration, consistency and interruptions. Whether you’re tracking workouts or monitoring your overall health, the Series 11 has all the features you need to be health conscious.
Apple Watch Ultra
For those who want more from their smartwatch, the Apple Watch Ultra is the ultimate choice in the Apple Watch Series 11 lineup. Designed for adventure and extreme conditions, the Ultra has a larger display that’s easy to read in any environment, plus better water resistance for swimming and diving. Enhanced GPS for precise location tracking and a built-in depth gauge makes it a favorite among divers and outdoor enthusiasts. The Apple Watch Ultra combines rugged durability with all the features of the Series 11, so it’s the go-to for athletes and explorers who need a watch that can keep up with their active lifestyle.
