Hypertension notifications with FDA clearance, and 24-hour battery life, the first increase Apple has given the standard Watch since 2015.
Released September 19, 2025 · From $399 (42mm GPS)

Hypertension notifications. The Series 11 uses the optical heart sensor to watch for signs of chronic high blood pressure over thirty-day windows, and it received FDA clearance shortly after announcement, which matters because roughly half the people who have hypertension do not know it. Battery life went to 24 hours, the first increase Apple has given the standard Watch since 2015, when 18 hours became the number everybody complained about. 5G arrived on the cellular models. Ion-X glass on the aluminum cases is now twice as scratch resistant. It is a quiet generation carrying one health feature with a genuinely large number of people on the other end of it.
Hypertension notifications, 5G and a 24-hour battery were the changes behind an unchanged exterior.
The Apple Watch Series 11 is a refinement of an already winning formula, packing a device that's always on your person with exactly the type of passive features you'd want in something like that.
With longer battery life this time, it promises to provide even more peace of mind.
