    After upgrading bird, rc and my 3 batteries the flight time is reduced to 13 minutes when flying normal under optimal conditions.

    Any one else have this issue?

    After 12 minutes i get 20%.
    Other battery 7 minutes --> 39%.

    Yes. It's a feature. There is more power than before on the motors for lift, descent and thrust which I'm sure accounts for the battery drain. I hope they fix this quickly.

    You need to take the battery down to 3.3v each cell (5-8%) and retrain it.. This should fix what you're seeing

    I hover it to about 10% and then sit it over an AC vent to keep it cool while it drains down to 3.3v on the ground.

    I drain batteries by putting a car headlight bulb of 55W plugged into the battery.
    Obviously keep an eye on the status lights to make sure its not taken too low.

    The manual gives how often they should be fully discharged.

    Which is every 20 charging cycles.
