I've been flying drones for over 10 years, starting way back with the Phantom 2 and now using the Air 2S and Mavic 3. Lately something occurred to me: I haven't had to calibrate the compass in over a year.

Back when, it felt like I was doing the compass dance every other flight—spinning in a circle like a goofball in public spaces just to get airborne. Sometimes multiple times a week, depending on where I was flying.

Now? Nothing. Even when traveling to totally new locations or different states, the drones just fire up and fly with no complaints. Honestly, it's been so long, I forgot where in the menu the compass calibration even was. That used to be something I had to do by second nature.

Has something changed in the hardware? Are the compasses more shielded or self-correcting now? Or is the software just less sensitive or smarter about when calibration is actually needed? Even when getting new drones through the mail, it occurred to me, I haven't even calibrated them at that point.

Curious if others have noticed the same thing
 
Has something changed in the hardware?
I think what has changed is many people have figured out it's not a best practice, nor is it something that needs to be done before nearly every flight.

When should you be calibrating the compass? See more details here:

Thanks for the reply, yes, I realize some people used to calibrate all the time. I was not one of them. I would typically only calibrate if I got a error on the controller saying calibration needed. My question is, I haven't seen that pop up in well over a year. Even when drones have been shipped from california, overseas, or on international trips. I just don't see it ever anymore.

Per the guide above, that's typically an indicator that you should not calibrate the compass. It normally occurs when the compass is/was near some type of magnetic metal source.
 
LOL, I'm not looking for guidance on when to calibrate. I'm curious if DJI changed anything in hardware or software. I used to get compass warnings a few times a week. Haven't seen one in well over a year

I'm not really offering guidance. Just pointing out the seemingly overlooked possibility that you may have been calibrating the compass unnecessarily.

Not that I'm aware of. This is how compass calibrations have functioned for some years now.
 
Something changed. Across dozens of drones, it wasn't unusual to get at least a compass or two calibration notices every single week. Now I don't get them ever. That's what I'm just trying to drive to the root of regardless if one took the advice or not.

What DJI changed was the misinformation about compass calibration that they spread for years in their manuals.
Truth is that you've never needed to recalibrate the compass of your drones.

The warnings were that your perfectly functioning compass was telling you that the spot you'd placed the drone was close to a source of magnetic interference.
Moving away from that was the proper action and recalibrating a perfectly working compass wouldn't help.

If you really want some answers, the first post in this thread will give you an understanding about what compass calibration actually does (rather than what you might have believed) and when it might be needed (almost never).

I've flown only about a dozen drones over the past four years, but I can count on one hand the number of times I've seen a screen message suggesting a compass calibration and still have a couple of fingers in reserve. Nor have I heard of anyone else encountering those messages so frequently.

Perhaps you were experiencing a unusual problems for some some reason and have changed your operation practices?

I simply wanted an answer of what DJI changed LOL. Regardless if it was needed or not, there are no longer any pop-up notifications. I was trying to understand what changed - the firmware or the hardware. Seems like firmware.

It wasn't firmware or hardware.
Read what I posted because I've given you the answer.

LOL, no you explained WHY there was a notification and the non-necessity of following it and what the calibration did or didn't do. That's all fine. Question was - why did the notification go away. So I am assuming that DJI realized it was unnecessary and changed the firmware to no longer have the pop-up warnings.

I explained what you asked for.
There was no change in firmware or hardware.

I haven't recalibrated any DJI compass in over 10 years.
The only time my drones brought up DJI's poorly worded compass warning, that makes users think they had to calibrate the compass, was if I placed the drone close to steel items.

Or if you want another example of DJI's very badly worded warnings, I would get what appeared to be a comp[*** warning when launching a Mavic 3 pro in the dark.
Although the warning said to recalibrate the compass, it had nothing to do with the compass and recalibrating wouldn't make the warning go away.

Or DJI were so stupid about their false instructions about the necessity to recalibrate the compass every 30 days or if you travelled 50 miles from the last flight, that they actually made the Mavic 2 refuse to launch unless you (unnecessarily) recalibrated for either condition.
This is explained in the post I referred to above.

But to answer your question, compass calibration has never been required and there was no firmware or hardware change made about this.
