Amazfit Watch faces

hello,
the bluetooth icon of my gtr 47mm version is always displayed, even if the bluetooth of my phone is turned off.
so it uses more battery all the day uselessly.
someone know how disable bluetooth on the watch?
thanks

Wich face do you use? Since an update all icons were messed up, big chance the icon is linked to lock icon or any other icon. I think the watch will always try to connect by Bluetooth
