Apple Watch Series 11 vs 10 - The Truth About the Upgrade!

Apple Watch Series 11 vs 10 is one of the hottest topics among Apple fans this year. Last year’s Apple Watch Series 10 stood out with its thinner design and edge-to-edge display, delivering an impressive visual upgrade. However, its battery life and core features remained largely unchanged, making it more of a design evolution than a functional leap.

At Apple’s Fall Event on September 9, 2025, the company officially unveiled the Apple watch Series 11. Powered by the new S11 chip, it promises better performance and efficiency, paired with a brighter LTPO display for improved outdoor visibility. Health monitoring may also see a breakthrough with the long-rumored blood pressure tracking. I’ve already covered the Apple Watch 11 vs Apple Watch Ultra 3 comparison, but how does the Series 11 truly stack up against the Series 10? In the following sections, we’ll compare design, performance, battery life, and pricing to help you make the right choice.
