Does BlueTooth have to be enabled at all times

Does BlueTooth need to be on at all times on the iPhone to be connected to the iWatch.? I usually only have it on when I'm connected to a BT headset as it uses too much battery.

Watch Series 2(Alum) 42MM (2nd gen), watchOS 3

Not everything is cut an dry Jonathan when it comes to devices.

When Bluetooth is disabled on the iPhone:


  • It is normal for no devices to be listed under "My Devices" on your iPhone (Settings > Bluetooth).
  • Even so, the watch remains paired to the iPhone. (It is just not connected to it, at that time, via Bluetooth).


The question was whether Bluetooth needs to be on at all times, on the iPhone, for the iPhone to be connected to the watch.


The answer is no; with both devices connected to Wi-Fi, they remain connected.


To verify this:


  • With your iPhone connected to Wi-Fi, turn off Bluetooth.
  • Wait for a few moments, then check (via Control Centre) that your watch has connected, as a fallback, to Wi-Fi.
  • Open the Camera app on your watch.
  • The camera viewfinder will open on your watch, showing the view from the iPhone's camera.

Hi


No, Bluetooth does not have to be on at all times on your iPhone for the watch to be connected to the paired iPhone or to use certain Internet-based services.


When your watch is unable to connect to the paired iPhone via Bluetooth, it will attempt, as a fallback, to connect to a known, compatible Wi-Fi network.


When connected to Wi-Fi, the watch still offers a number of features. If it is unable to connect either via Bluetooth or Wi-Fi, it again still offers some - although fewer - features:

For the best performance from your iPhone and Apple Watch, including the most power-efficient communication between them, Apple recommends keeping both Bluetooth and Wi-Fi permanently enabled on your iPhone.

You need it only if you are using the features of the watch, that require a paired iPhone.


Without bluetooth it will be like you left our iPhone at home. Your watch can still do these tasks - quite a lot:

Frequently I leave the iPhone at home, if I do not expect to have to make phone calls.
