Honor Teases Watch 6 Pro Ahead of Sept. 28 Launch With Cardiac Arrest Monitoring

Q: Will Honor's promise of 35-day battery life hold up under the heavy strain of continuous blood pressure and cardiac tracking?

Probably not at the full 35 days if those health features run continuously. Honor’s 35-day figure appears to come from the broader Watch 6 platform and is typically tied to light or “typical” usage, not the heaviest sensor load. The standard Watch 6 pairs that claim with a large 980mAh battery, but even favorable hands-on reporting suggests more realistic endurance is around five to seven days with GPS workouts, notifications, sleep tracking and continuous health monitoring switched on. That gap matters when judging the Pro model’s new cardiac-arrest alerts, seamless blood-pressure monitoring 2.0 and Smart Eye Sensing system. Continuous cardiovascular tracking is one of the most power-hungry things a smartwatch can do, especially if it is sampling frequently in the background, analyzing trends, and keeping emergency detection ready at all times. Add an AMOLED display, Bluetooth, notifications and possible GPS use, and battery life usually falls well below headline maximums. That does not mean Honor’s claim is false. It likely reflects a best-case mode with reduced screen wake-ups, limited workouts, and less aggressive health polling. The company has not yet published the precise test conditions for the Watch 6 Pro’s battery under nonstop blood-pressure and cardiac monitoring. So the real answer is that 35 days may hold only in conservative use. Under the heavy strain described, buyers should expect materially shorter battery life until independent tests confirm otherwise.

September 28 is the China launch date for Honor’s Watch 6 Pro, whose latest teaser shows two versions and confirms reservations are already open on Honor Mall, Tmall and JD.com.
Two designs appear in the teaser—a dark sport model with yellow accents and a silver version with a brown leather strap—both using a circular case, numbered bezel, two right-side controls and a red-accented crown.
Honor says the Watch 6 Pro will be its first wearable with a dedicated cardiac arrest monitoring system that tracks heart activity and warns users during emergencies, though it has not detailed the detection method.
Continuous blood pressure monitoring will also be included through Honor’s Smart Eye Sensing system, extending health features beyond the anti-sudden cardiac arrest risk screening previously offered on the Watch GS 5.
Pricing and full specifications remain undisclosed until launch, leaving the health system’s exact operation and broader hardware details to be clarified later this month.
