I would be surprised if that were the root issue as that introduces some common scenarios that should reproduce that issue:
- user driven: battery in body is empty, user shifts to grip
- camera driven: camera automatically shifts power to grip
I do think the grip played a role in the power/battery monitoring as a I should be down by half (if not more) if I took 400 shots. This probably points more so to a power management/utilization issue. Researching some similar threads, users were able to resolve the issue by swapping out the battery. Taking the battery monitoring into account, that may have been the culprit and the 'grip' was probably just a variable that stands out.
