Apple’s new wearable has done fairly well since its release selling many units though notably falling under predicted expectations. Last week, the device got its first major firmware update, and some users are not happy about a change to one of its core features, the heart rate monitor.
When the Apple Watch first shipped, the heart rate monitor was tracking your vitals every ten minutes no matter what the user was doing. After this latest update, however, the Watch will now only take a heart rate reading when you’re staying still unless you manually trigger a reading via the heart rate Glance tab or by initiating Workout mode.
According to Engadget, there is no known reason why Apple made this change although it has been confirmed to be an intentional move by the company, and it is safe to assume that it may have enough of an effect on battery life to warrant the decision.
