p.1 #1 · Keeping Bluetooth & Battery Drain

Will keeping BT on, for possible use with my Sony BT remote negatively effect my battery? This is on my A7RIII.

I keep the BT active on my A7RIII all the time for GPS connection with my phone. I've never noticed any excess power draw/loss as a result.

You're running a short range radio transceiver. That requires power.

Note from camera manual that may be useful:

While [Bluetooth Rmt Ctrl] is set to [On], the camera will not switch to the power-saving mode.

So if you forget to turn off camera and put it in a bag, it will not turn off on its own, but it will drain battery completely. If you catch it before complete drain you will notice that camera is hotter than usual. That happened to me few times.

OP here�.it�s sounding like the best practice is to turn it on and off based upon needing to use the remote.

For what it's worth, the a7RM4 has more granular control over some of these connections.

OR, if granular control isn't necessary, just set Airplane mode to ON. Assuming here the a7rIV has it.
