Hey all,

First time DJI owner so I don't have a lot of experience with the ins/outs of ownership. I bought the Fly More combo so I have 3 batteries.

After flying, I always plug in all 3 batteries and charge them up. After charging is complete for all 3, I load 1 into the Mavic Air and put the other 2 in the case. With the crazy spring weather, I can't fly that often yet, so the fully charged batteries tend to sit for a week or so without use. They are inside in my office at about 68 degrees F. Basically optimum storage between useage.

What I am noticing is that the next time I fly, the battery is at about 50-55% charge when I first power on the Mavic Air. The same goes for the other 2. So absolutely no useage in between fully charging and the next flight.

I do see that the batteries all achieve 100% charge if I charge overnight and fly the next day, so I don't think they are faulty.

What's the deal here? Do Mavic Air batteries drain when not being used? I imagine any battery (Mavic Air or otherwise) doesn't hold 100% charge when not in use, but a 50% drop in charge after a week seems EXTREMELY excessive. Wondering about others experienced more with DJI and their products, either the new Air or previous drones.

hi, this could be normal behaviour. Check in your battery settings menu where you will discover an option for amount of time to discharge. it is not recommended to hold full charge in the battery for more than a few days because this has negative effect on battery cells and decreases the overall battery life. Therefore the option exists to automatically discharge after a certain amount of days (mine is set to 3 days) - this to protect general battery health and limit risk of self combustion or other risks. hope this helps - check out the options in your battery settings menu

In Mavic Air there no setting in DJGo app. Discharge time is fixed to 10 days.

U shouldnt be charging your batteries and letting them sit fully charged....not even 2 days....u should leave them in storage charge or 35 to 40% till the day u are ready to fly....things that make lipos go bad fast and lose life expectancy are: leaving fully charged for days....over discharging to below 10% all the time. And leaving them sit depleted ie 10%

Correct pawel so what he should do if he is not flying for a week is discharge them to 3.80 v (storage voltage....which equates to somewhere around 35 to 40%

I am having the same problem, which now I understand is not a problem.  I have been storing the batteries on the charger and am only getting 50% battery.  The last time I used it, I pulled the batteries out of the charger and put them back in to reset it and I still only got 50%.

I so wish people would read the manual for their new 'toy' before asking, what turn out to be, stupid questions & making ill-informed statements!
