After the Watch OS 1.0.1 update, some Apple Watch users are reporting that the watch is not sending the consistent heart rate data to their paired iPhone. Before the software update, the watch was functioning properly and used to record and send the data as usual at every ten minutes. What could be the reason behind this inconvenience?
The watch is equipped with a heart sensor that reads heart rate with the use of photoplethysmography technology. The recorded data is stored in the Health app on iPhone. There could be many miscellaneous reasons why the watch is not able to send the data consistently like skin perfusion, motion and temporary or permanent changes to the skin.
#1. Skin Perfusion: It depends on the environment and varies from person to person.
#2. Motion: The watch can measure heart rate if your body is in rhythmic motion like running or cycling.
#3. Changes to Skin: Any temporary or permanent change to the skin like; scratch or tattoo may prevent the watch from recording the heart rate.
According to Apple, even in the ideal situation, the watch can’t send reliable heart rate every time. The Watch measures heart rate regularly at every ten minutes but won’t do so, if you are in motion, or your arm is moving.
