A7Rii Battery Grip Draining Power

[alh00020]

Hi all,

 

Have noticed in my last two or three outings that using the A7Rii with the battery grip appears to drain the 1st battery even faster than when using the camera without the battery grip. Last night, I returned from shooting and took a single battery out of the grip to charge, leaving the 2nd battery in. The camera was switched off with the battery grip attached (also switched off), and I have just turned it on 24 hours later to find that the battery that was at 100% is now at 85%.

 

Has anyone else found this occurring? Any solutions out there that I am missing? 

 

Many thanks,

Alex

It`s the same problem which I described in the topic "Battery drain without using the camera (A7mII)".

Without battery grip it`s the same. One week and the battery stays with 8_12%.

Sony doesn`t know that OFF means OFF  or they are not able to write Linux.

The only way to solve this problem is to get an firmware update.

Anybody has got an idea to convince Sony instead of writing stupid apps to develop a better firmware???!

Remove the battery.

Yes, that is an apt description of the situation, its possible to come up with a more complex reasoning if you want:

Not that it helps. Firmware update should fix it       expectation update might help too
