Controller battery level after extended storage

[kc9sdo]

I have to confess that my Mavic Pro hasn't been out of its case since last fall. Today, I decided to recharge the batteries and update the software in preparation for some spring flying.

I checked the flight batteries and they were still at 3 bars as expected with the automatic discharged after 10 days. What was surprising was that the controller was at 1% when I first started charging it. I know it was turned off when I put it away, so it must have discharged this much during 5 months. I hope this hasn't shortened the battery life of the controller. Has anyone else experienced this amount of discharge with their controller?

havent left mine that long but after a week its still at 100, thats strange it was so low after that time, hope it charges up well and holds a good charge

That is known, it will drain like 10% a month when unused.

This is normal with the controller. It drains when it's not used, you have to charge it every few weeks.

DJI recommends keeping the remote between 40% and 60% when you're storing it.

I was able to charge the controller battery up to 100% and it doesn't appear to have any issues holding a charge.

If it does prove to be compromised you could tape a powerbank to the back and get another season from it
