The smart watch hasn't been notified!? --Because I can't hear it anymore, why is it an iPhone?

As the name suggests, a smart watch that advocates "wisdom" is a watch that will be a good buddy of the iPhone.Of course, there is a difference in performance depending on the model, but if you charge it once, it is not unusual for power -saving design that you do not need to charge for more than a week, and the function that will inform you of the arrival of calls and notifications on the iPhone by vibration/screen display.It is prepared like.

Most of the smartwatches use Bluetooth for most products with the iPhone.Moreover, among the Bluetooth standards, BLE (Bluetooth Low Energy), which has a particularly low power consumption, is used, so the power consumption is very small.Even if you always wait for notification from the iPhone, there is no power consumption that you can make an eye on the iPhone/smart watch.

However, suddenly the notification may not arrive.The first possible reason is that the Bluetooth on the iPhone side was turned off.This can be dealt with by checking the state of Bluetooth at the control center.

It is also possible that the communication between the iPhone and the smartwatch has been disconnected.Normally, if the iPhone and smartwatch are within a 10 -meter radius, communication will not be interrupted, and even if it is interrupted, it will be automatically reconnected, but communication may be interrupted for some reason.This problem is mostly resolved if you reconnect with the smart watch management app on the iPhone side.

Another reason is that the iPhone side "Share System Notification" switch is turned off.This switch appears when you open the screen in the order of "Settings" → "Bluetooth" and tap the "i" button on the right side of the device name of the smartwatch.I can't let you know.If the switch may turn off when the iOS is updated, let's make sure that the smartwatch has not arrived recently.
