Summary: Apple Watch Series 11 adds hypertension notifications (trend‑based), a sleep score, tougher cover glass (2× more scratch‑resistant), 5G, and a stated up to 24‑hour battery.
Why it matters
The health stack inches closer to proactive screening, while 5G and a tougher display improve daily reliability for mainstream buyers who don’t need Ultra’s bulk.
Key facts
- Battery: up to 24h; fast charge: ~15 min → up to 8h (Apple claim).
- Health: non‑diagnostic hypertension notifications based on 30‑day trends; new sleep score.
- Availability & price: from $399; launched alongside Ultra 3 and SE 3.
What to watch
Regulatory rollout for hypertension notifications by region; whether 24h battery holds up across heavy LTE use; repairability and glass durability in the field.
