Comparing Features: Apple Watch Series 11 vs. Series 10
The Apple Watch Series 11, launched on September 23, 2025, is the successor to the Series 10, which has been replaced and is no longer available for purchase. Both models maintain a similar design, but the Series 11 introduces several new features and improvements that distinguish it from its predecessor.
Design and Build
The Apple Watch Series 11 continues the legacy of its predecessor with a shared case design, measuring 1mm slimmer at 9.7mm. The Series 11 offers two size options: the 46mm model weighing 37.8 grams and the 42mm model weighing 30.3 grams. A new addition to the Series 11 is the space gray aluminum option, while the titanium models are made from 100% recycled titanium. Furthermore, the Series 11 utilizes 40% recycled glass for its display and features a battery constructed from 100% recycled cobalt.
Display and Durability
Equipped with an LTPO 3 OLED display, the Series 11 boasts an always-on display that refreshes once per second and reaches up to 2,000 nits of brightness for improved visibility. The aluminum models of the Series 11 utilize Ion-X glass, which offers enhanced scratch resistance, while the titanium versions feature a sapphire crystal display. Both models remain water-resistant, making them suitable for swimming and other water-related activities.
Performance and Connectivity
Both the Series 11 and Series 10 are powered by the same S10 processor, ensuring consistent performance across both models. However, the Series 11 introduces redesigned cellular antennas and supports 5G networks, enhancing connectivity with more efficient 5G RedCap technology. In contrast, the Series 10 only supports LTE and UMTS (3G) networks. Both models are equipped with Wi-Fi 4 (802.11n) and Bluetooth 5.3, providing reliable peripheral connectivity.
Battery Life and Charging
The Series 11 offers a notable improvement in battery life with up to 24 hours of usage compared to the Series 10's 18-hour battery life. When using Low Power Mode, the Series 11 can stretch its battery life up to 38 hours, slightly surpassing the Series 10's 36-hour capability. Additionally, the Series 11 supports fast charging, reaching 80% charge in approximately 30 minutes.
Health and Fitness Features
With the introduction of WatchOS 26, both the Series 11 and Series 10 benefit from new features such as hypertension notifications and a Sleep Score feature. The Blood Oxygen app, available in the U.S., continues to be a part of both models' offerings. The Series 11 enhances its fitness tracking features and introduces new health monitoring capabilities, building upon the reliable fitness tracking system of the Series 10. Both models are also compatible with Apple Fitness+, providing users with comprehensive fitness support.
In conclusion, the Apple Watch Series 11 offers several significant upgrades over the Series 10, particularly in terms of display brightness, battery life, and connectivity options. These improvements, along with its commitment to sustainability through the use of recycled materials, make the Series 11 a compelling choice for new users and existing Apple Watch enthusiasts.
