[QUOTE="NyJosh, post: 34856, member: 6744"] As this is a "smart" battery, I suspect it's like most modern smart phones where the percentages displayed to users are the usable amount of the battery and that there's still a buffer. Since lipos generally shouldn't go below roughly 5% at the low end and 95% at the high end, they just program them to display 1% when there's 5% left and 100% when charged to 95% total capacity. This is why you can press the button when it's supposedly dead but still light up the LED's to see the charge status. I wouldn't worry about it. If you do a scientific comparison between the battery you're worried about and another and find it's no longer performing properly, open a warranty case with DJI and they'll likely replace it if it's within 1 year of activation or whatever they say the top number of recharge cycles is (I vaguely want to say 240-250).
