ZV1 Battery Life

[Gillincs]

New to this forum and may not be in the right area but would very much appreciate any offers of advice. Does anyone else have issues with the battery life of ZV1 camera? I’ve had my camera 3 months now, have hardly used it but have had to recharge the battery dozens of times. Battery doesn’t last very long when camera’s being used but my main issue is with its rapid discharge when the camera’s turned off. It’s been back to Sony twice and they report there’s nothing wrong. With airplane mode on and Bluetooth off, and the camera doing nothing except sitting in a drawer, shouldn’t the battery remain charged for more than a few days? Thanks in advance for anyone’s help.
