Apple Watch Series 11
Hypertension alerts, 5G and a full day of battery.
Overview
Series 11 was a steady refinement of the previous design, with improvements most visible in endurance and durability. Battery life increased to 24 hours of normal use, and the new 5G modem meant that cellular models could connect on newer networks while sipping less power.
The aluminium cases got a stronger Ion-X front, which Apple said resisted scratches twice as well as before, while titanium models kept a sapphire crystal. The S10 chip stayed on from the previous year.
On the software side, watchOS 26 added hypertension notifications that look for patterns of high blood pressure over 30 days, and a Sleep Score that rates rest quality. The watch also gained a wrist-flick gesture to dismiss alerts, showing that Apple focused on small daily conveniences.
Why it mattered
Brought hypertension alerts and 24-hour battery to the mainstream watch without changing its shape.
