DJI Mini 2 batteries are not auto-discharging

Dug my Mini 2 out today as it’s been hiding in its case for two or three weeks now so thought I’d charge up a battery and install the latest firmware updates, etc.

I was surprised to see all three batteries sitting in the hub were all still fully charged :thinking:

I’ll fire it up later and double check but I’m pretty sure I set them all to be 10 days each.

Anyone noticed if their DJI Mini 2 batteries are actually self-discharging correctly?

I might be wrong but I’m pretty sure the original Mini didn’t self discharge. My mini 2 has been hiding for a couple of weeks, let me check…

Still fully charged

Mini 2 has LiPo batteries, Mini 1 Li-Ion. Longest I’ve left my 2 is 2 weeks, they’d lost a bit which I assumed was as described in the manual.

Can you set that in the Fly app, I thought is was all auto on the Mini and 2.

Mine have lost about 10% after been in the bag for 3/4 weeks when I took it out yesterday

That’s right, it also didn’t need to as @Doodler points out they were Li-Ion batteries.

You have me doubting myself now, will confirm later.

The manual suggests I should see some depletion though :thinking:

Just turned the Mini 2 on to install the firmware and check this:

Nope, you’re right.

There is absolutely no option in the Fly app to set the number of days for the batteries to discharge.

Does the Air 2 have this option? :thinking:

Anyway, original question still stands I guess, has anyone seen their batteries discharge more than 10% so far? :man_shrugging:

No it doesn’t. Or not that I have seen.

I thought all LiPo batteries discharged automatically?

All “intelligent” batteries are supposed to.

Hey Rich no the Air 2 has no option to change discharge time that I know of. My Air 2 batteries discharge fast to around (65-70%) in about a week. Well it seems fast to me, not sure if that’s about the ballpark figures for every Air 2?

Just checked the manual and it seems this is around the right figures for an Air 2

Weird… so it seems like the Mini 2 batteries are not behaving as DJI intended then :thinking:

Hmm, last time I checked I think at least 1 LED was off on all the batteries after leaving them for around 3 weeks. Not 100% sure though :rofl:. I do know that I charged them after the three week period so…

Well, they are intelligent batteries after all, perhaps AI is already with us :thinking:

Just stumbled upon this… seems 72% is the magic number.

My reading of this is that the battery will discharge to 72% and then stay there?

Isn’t that what I posted a couple of days ago @JoeC? :blush:

No, it’s entirely different… definitely.

In my defence, I’m a little bit tipsy :wink: :tumbler_glass:

Mine (3} have been left longer than 5 days and aren’t discharging to 72%. Typically just over 90% after about 10 days.
