That's not what the tech at my DJI store told me. He said there should be no battery drain at all when the battery sits in the drone with it off.

It's hard on LIPO batteries to store them fully charged for long periods. The "smart" battery will take itself down to like 97% if left fully charged for a day, and to a proper storage level if left for a certain period.
I often charge batteries, figuring on going out later, then something happens and I don't go out. Then something delays me a few days. Then my batteries are dead. Not sure I'm using them quite as DJI intended
.I figure, as fast as drone technology advances, that they'll still last longer than I'll be interested in them.
Expected behavior with the autodischarge. They will drain no matter what you do, including leave them in the charger, if you don’t do a new charge cycle.

So now one picked up that he flew 1KM away? LOL. Would think that was tad behond VLOS. . As for teh battery, always charge them all at same time to be sure you don't run into this situation or one where you discovered you don't have a charged battery....can ruin a trip to go fly real fast.

Even if the battery wasn't in the AC it would have done that. The auto discharge brings the charge down to about 60%. I wouldn't call that dead though.

Ya maybe. I am checking the manual now.
It looks like I will transport and travel with my drone with all 3 batteries out until I turn it on. Not worth the drain.

If that's the case, wouldn't it be a better idea to just leave all the batteries on the charger and remove it right before you plan on flying it? As opposed to taking it on and off the charger. I would think it would save the discharge cycles.
Don't DJI batteries only have something like a 700 discharge cycle life?

Thanks, good to know this. Too bad they still drain when in the charger, otherwise I would just leave them in there all the time when in storage.
These are Li-Polymer batteries and I never did a complete 100% to 0% cycle on any of them. Close but not right now to 0%. Hopefully I still get peak battery life out of my 1 week old batteries,
So that makes me think that even though these batteries auto discharge from sitting unused, it's best to just charge them the day of or night before you plan on flying and not every couple of days. This way you are only using one discharge cycle and not several.
So if you do a new charge cycle, then the auto drain will be stopped? Doesn't the new charge cycle have to be done literally the very first time that battery is used? Otherwise will it still be effective after the battery has been used one or two times?
When you put the batteries on your charger they will charge to max regardless of reason for charge depletion. They will then start a new auto-discharge cycle at the time specified in their programming.
Charging within 6-12 hours of flights is my method.
Having the charger maintain a constant full charge would be the worst thing for the batteries so it's a good thing the battery stops charging when full and not start charging again until removed from charger/hub.
As an example laptop batteries seem to deteriorate prematurely if left on constant charge, or if left uncharged for extended periods.

In the fly app.
Connect to fly. Then click the ... button in the top left.
Select the About tab.

Wow! I obsessively watch the battery level. Hopefully I don;t get complacent when I'm not all puckered up tightly flying in the future when I have more experience!!
Laptop batteries won't wear near as quick if plugged in 24/7 versus constantly draining it down to almost 0% everyday. I know tons of people who drain their laptop batteries daily because they never run it on AC power and in a year, their battery life is half what it was when new.
I have my powerhouse laptop at home plugged in 24/7 at my desk because it doesn't get moved around much, but I drain the battery once a month and the battery is still 98% after almost 2 years of use. Have always been told that if you have a laptop plugged in 24/7 to cycle it once a month.
