I am having the same problem over here.
I have total of 6 sets of batteries and 2 sets have 1 battery each going from 85% -> 0% in 1-2 minutes in air.
Made a thread about it also but no answer from DJI - https://forum.dji.com/thread-176990-1-1.html
Battery health check in DJI GO app shows Normal for status, but shows 0% and for some reason I2 only looks at this percentage when doing the auto landing or RTH calculations.
I contacted DJI via email and they said that i need to buy new batteries.
This is their first answer -
Thank you for writing DJI Support.
We are very sorry to hear about the problem you are having with your DJI product.
Based on the details you have provided, it indicates that the battery is outside of the warranty period. And upon checking with our engineers, this needs to be replaced.
Lithium polymer batteries require special care on how they are charged, discharged and stored which therefore concludes that the battery's health and lifespan will depend on usage. Once you are out of the warranty period, we can no longer provide warranty service as the lifespan of your unit will depend on the totality of how it was used and all.
Because of the structure of the battery, it cannot be repaired. If it is out of warranty, we will just replace it with a new one by charging you as the price of a new battery. If so, we don't suggest you send them back. You can buy a new battery from an authorized DJI dealer or the DJI Online Store. https://store.dji.com. We are sorry for the inconvenience, and we appreciate your understanding in this matter.
And this is how i responded -
Hello,
But this is a firmware (software) issue not a hardware issue.
I don't quite understand why it needs to be replaced.
Issues started with the last firmware update when you tried to mitigate the TB50/TB55 issues.
Battery itself it totally fine. By fine i mean It shows correct cell voltage levels, no anomalies there.
It's the charge percentage software bug that causes the issue.
By reading the dji forums and other forums, other people also have the same issue and it seems to be a battery manufacturer firmware issue and DJI is waiting for the firmware fix from them.
And i got this answer back from them -
Thank you so much for your time.
I agree with your concern about waiting for the firmware update however, the implementation of that solution has been suspended and advised customers to send back their batteries to our facility.
In your case, since the battery is out of the warranty period, we advise you to purchase another one and the good thing about it is you will be getting a new fresh warranty.
Hoping for your understanding with this regard.
Thanks for choosing DJI.
Like seriously DJI are you really punishing your customers for your own programming mistakes?
