This looks really cool and happy to see a clinically validated watch but am I the only one who does not see any mentions for battery life for this watch? Even in their FAQ section they just have a question about low battery indicator but nothing on how long does it last.
Power source: 1 Lithium ion polymer rechargeable battery, AC adapter
Battery lifespan: Will last for approximately 500 cycles, 8 times/day measurements in normal temperatures of 77 °F (25 °C) when new battery fully charged
Battery life: A typical user can expect to charge HeartGuide approximately 2-3 times per week, depending upon the frequency of use of HeartGuide’s features
I looked up what "clinical validation" meant for blood pressure monitors -- apparently it's a real term with a (somewhat) specific meaning! Omron lists all their devices, and what they passed [1]. Interestingly, out of dozens of devices, this is the only one they make which isn't validated by ESH-IP. I wonder why.
