That was probably nothing. The battery is either almost empty when I put him in my X20 or he breaks down quickly and are so few photos up the ghost. Discharges probably quite fast even and if he has the specified capacity, I doubt, at least. So I'm considering just create one original battery and to feel confirmed so far never have resorted to third-party batteries. Happened to me not so quickly. Den here I would certainly not buy it again. Not even for 5 seconds.
