How do I get rid of this 'Disconnected Icon' when BLUETOOTH AND LTE are both not enabled?
The symbol looks like a phone with a line/strike through it. Never had this issue on previous Galaxy Watch.
You can't disable that icon because the watch is meant to be connected to a phone via Bluetooth. I personally don't see the purpose of a wearable with a big screen just for checking the time with it, and not also use it for notifications. Bluetooth, nowadays, doesn't even consume that much power when enabled and connected, it's not called Low Energy for nothing. It doesn't really affect any wearable's or phone's battery runtime.
I have wifi and data on, not connected to my phone (its out in the car, im inside at work) and this symbol wont go away. Turned off watch and back on, still there, can't get it to go away.
That's because it needs to be connected to the phone via Bluetooth, meaning directly to it. It will appear with the remote connection as well. It is a crossed-out phone, it should be pretty clear what that means - the phone is not nearby.
That icon will only disappear once the watch is connected to the phone via Bluetooth.
