First time this happened I assumed I had left the camera on and chalked it up to something strange but a once off, but it seems it happens every time, i have two genuine EL-EL15 batterys and I fully charge them and put in camera, but overnight the camera goes completely dead and the batteries need full recharging again, and its both batteries, so I reset all my menu options back to factory just in case I had done something unawares but it happened again last night, I dont have high hopes for a quick fix but it happens to be wedding season here so slightly in the poo considering the nikon repairer for NZ is a long away and i hate to send my camera on the courier anyway, has anyone else had this experience??
