Batteries drain quickly.

[DavidBlezard]

I have not used my mavic for about a year. Drone and batteries were stored in my house at normal living space temp 70-75 F.

this month I charged all the batteries and controller. Went flying. The batteries seem to only last about 10 minutes.
Is there a way to renew/refresh the batteries to get back to the 25-35 minutes they used to last?

If you post the recorded flight data from one of those flights, it might have some information about the battery's status.
