I hope they do the right thing and replace your bird! Alot of people are explaining how the battery monitor works, which is great, but the 'why' has absolutely no bearing on whether its a hardware failure VS user error.
Not everyone that buys a drone is on this forum reading about it's glitch's (nor should they be expected to). The battery should either indicate the true charge or it should auto block use when it has been sitting around for X hours. The only way I would put this liability off the companies shoulders is if it clearly states on the battery that the charge indicator is not reliable after X hours of non-use. Then the user was clearly warned.
