Got a battery around a year old now but still according to my assistant software says there is still 90% life left in the cells. I get only 2-3 minutes of flight when the percentage level on screen still says 80%. Is this normal and just time to get new batteries or is there a trick in repairing the problem. I have tried draining the charge to under 8% then re-charging fully. Please see my YT video attached.
