How much data does the Apple Watch use?

[iMore Question]

Data usage.

 

[Just_Me_D]

If you're referring to cellular dat then I'd say none. Remember, the Watch is connected to your iPhone via Bluetooth, and is dependent on that connection, with the exception of being able to connect to a remembered Wi-if network.

Data usage.

Well it basically depends on the apps you are using on it.
It is connected to the iPhone via Bluetooth and use cellular data via the iPhone itself.
