Anyone just leave the OP-Z connected to IPhone/IPad via Camera kit/OP-Z cable

I just started leaving my OPZ connected to IPhone/IPad via Camera kit/OP-Z cable. The Bluetooth seemed to drop a lot (and I like the OP-Z app), and its ready to go for sampling from iOS apps. Does anyone else do this? I guess I thought you HAD to use the Bluetooth for connecting to the app.
