My phone (OnePlus 7T Pro) has a sleep standby optimization that preserves battery life when it detects the phone is stationary at night time. When the phone is moved again in the morning, the optimization mode is switched off and all connectivity is restored. The FR945 however doesn't reconnect to the phone, which means that every morning I need to turn off BT manually, and turn it back on in order to regain the connection to the watch.
Has anyone experienced this?
