Battery faster empty after FW upgrade

[nikon.]

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

How can I do that?

How can I do that?

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.

Have I to do this every time or 1 in 10 charges?

The manual gives how often they should be fully discharged.

The manual gives how often they should be fully discharged.

Which is every 20 charging cycles.
