Users who tested the Apple Watch with the first version of Watch OS were able to experience that the smartwatch made a very reliable record of the heart rate every 10 minutes, when upgrading to Watch OS 1.0.1 some realized that the records were no longer made as often , which was thought to be a mistake of this new update.
Apple, with the aim of not considering this difference as an error, has made a new clarification through its website, where it says that the Apple Watch tries to measure our heart rate every 10 minutes, but it will not be recorded if we are in motion or if we have our arm in motion, something that can be considered a delay since Watch OS 1.0 did not care about the movement of our arm.
We don’t know why Apple made this decision, it’s possible that they noticed that with the movement the device loses precision, other comments say that it could have been because this function punished the battery of the device, something that could have been solved by allowing the user to choose whether to use it or not. The main problem is that this is causing a lot of complaints from users who had bought the device with version 1.0 and now it has lost one of its features.
A rudimentary solution to this problem could be to use the Apple Watch Training application and force the system to perform a continuous heart rate check, which would record heart rate measurements every 10 seconds. This has two disadvantages, the first is that unlike the passive mode, we will now have to remember to activate the function if we want the heart rate to be counted, the second and most obvious one is the battery one, since by doing a continuous recording we will spend much more battery. Hopefully the next Watch OS update will let the user choose what he wants.
