    I have my A7R2 in air plane mode to save on battery power but what else is sucking the battery down when not in use and switched off?



    does any one know how long memory, copyright info etc is stored if the battery is out? is it stored on a eprom or is there a backup battery inside ?

    There is always going to be a bit of a drain just from sitting, but it should not be very much.

    As you said, the camera maintains a lot if setting data, but this should be extremely minimal and not affect battery life in any significant way.

    If you are having more than a few percentage point in loss over a couple of days I would look for a new battery.

    Battery removed for 48 hours and had no power loss nor was there any loss of date ,time or copyright settings, hopefully the answer is pull the battery when not in use and not loose the embedded data
