Canon G7X Mark II - got the battery warning after second full charge and about 20 minute's use.

If this occurs once per charge it won't bother me to save some money, but if it's going to be appearing frequently, and shutting my camera off as it does, it's going to be a problem. I can't be in the middle of critical Manual shots and have my camera shutting down.
