Firmware Update Apple Watch caused an uproar in some users due to disruption of the heart rate sensor.
If earlier the pulse of the citizens clearly
was checked every 10 minutes, the Watch OS 1.0.1 it comes with different, sometimes very long intervals. According to the updated official website Apple Watch, the sensor is still working properly.
Simply put, a change in the working time heart rate is a feature, not a bug. The fact that the Watch OS 1.0 HR metering system has been configured so that every 10 minutes the pulse check the user, regardless of its activity. Watch OS 1.0.1 in the same pulse is measured under the scheme only when the clock hand real estate. If the user moves the said limb, for example, while walking or any other activity, heart rate measurement is not done.
However, you still have the possibility to force Apple Watch to measure the pulse of the time - you need to activate the training mode (run the application Workout), after which the heart rate will be determined every 10 seconds. But such a regime Neshchadim to charge the battery.
Unfortunately, Apple does not explain the reasons for the change of heart rate measurement. Maybe the company is trying to save battery life. The second likely reason - inaccurate measurements of heart rate due to hand movement, which leveled out at 10-second interval (in training mode), but become critical if the metering is done every 10 minutes. Either Apple has decided that more important than ever to measure only heart rate at rest, but that did not accurately determined energy expenditure while walking. I am personally inclined to think it's all about the struggle to increase the autonomy of the gadget.
