Last year's flagship, which Apple no longer sells but stores are still clearing out. It has the ECG app, blood-oxygen readings, hypertension alerts and a 24-hour rated battery, and Wirecutter recommends it at the right price. It misses the Series 12's continuous heart-rate tracking, Readiness score and longer battery, and Tom's Guide says it's barely changed from the Series 10.
Common Apple Watch Series 11 problems
- Discontinued, and missing the Series 12's new tools
Wirecutter says Apple no longer sells it. Compared with the Series 12, you give up longer battery life, all-day continuous heart-rate monitoring, the Readiness score and the Audio Intelligence features.
Source: Wirecutter (Apple Watch guide) - Little change from the Series 10
Tom's Guide says it's so close to the Series 10 that it makes you wonder why Apple released it. Its review notes the same design and the same display brightness, and says Series 9 or 10 owners may not find enough to justify switching.
- Still a daily charge, and limited AI
It's rated for 24 hours (38 in Low Power Mode). Tom's Guide lists limited AI features as a con and says watchOS 26 brings no meaningful Siri upgrades. Amazon's review summary, by contrast, is entirely positive, and only about 5% of ratings are 1 or 2 stars.
What owners like
- A full day and night on a charge
Tom's Guide says it's the first regular Series model rated beyond 18 hours (24 hours); the tester lost only about 20% overnight. Wirecutter measured 82% after 30 minutes on the charger. Amazon owners praise the battery life and quick charging.
- Full set of heart-health tools
ECG, blood-oxygen readings, hypertension notifications, sleep apnea notifications and a Sleep Score (Tom's Guide, Amazon listing specs). Wirecutter says it will also get the redesigned Health app.
- Tougher glass and 5G
Tom's Guide says the display glass is twice as scratch-resistant as before, and the cellular model moves from LTE to 5G.
- You use an Android phone
- You already own a Series 9 or 10
- You want the Readiness score or all-day continuous heart-rate tracking
- iPhone owners who want ECG and hypertension alerts without paying for a Series 12
- Buying leftover stock on sale
- Upgrading from an Apple Watch older than the Series 9

What experts say
- Wirecutter (NYT): The competition (updated 2026-09-17): no longer sold by Apple, but recommended if you find leftover stock at a good price. It has excellent health and fitness features but misses the Series 12's battery, continuous heart rate and Readiness score.
- Tom's Guide: 'Also consider' (updated 2026-09-21): the pick if you need more hours from an iPhone watch, though it's very close to the Series 10.
- Tom's Guide (Series 11 review): A well-rounded upgrade with 24-hour battery, hypertension alerts and a sleep score; the cons are the same display brightness as the Series 10 and limited AI features.
