DJI Mini 3 Pro Range – Poor or PRO?

The DJI Mini 3 Pro is the latest addition to DJI’s famous sub 250g line. These drones weigh less than 250 grams and hence don’t need drone registration with the FAA.

The new DJI Mini 3 Pro is a very capable drone that has all the cutting edge features including a long range. Today, we are going to discuss the DJI Mini 3 Pro range and see how far can it go from the controller without losing signal strength.

The DJI Mini 3 Pro has a maximum range of 12km (7.5 miles) when you are in an open area with no interference and obstacles. It uses the newest DJI transmission system, OcuSync 3.0, which is quite powerful. However, physical obstacles, signal interferences, and local regulations limit how much distance the drone can actually travel.

Apart from the DJI provided numbers, I have also discussed the real-life experiences of different pilots at the end of the blog so make sure you read till the end to fully know the DJI Mini 3 pro range capabilities.

DJI Mini 3 Pro Range

When we talk about how far can the Mini 3 Pro fly i-e flight range, it can mean two things:

  1. How far the drone can receive transmission signal from the remote controller (transmission range)
  2. How far the drone can go from the remote controller before running out of power (battery range)

Let’s discuss both and see how the DJI Mini 3 Pro performs on both of these.

Transmission Range

The DJI Mini 3 Pro uses the proprietary DJI transmission protocol called Ocusync 3.0 which has a theoretical range of 12 km. The drone can transmit and receive data from the remote controller at that distance provided there is no interference and no obstacles.

In practice, however, the range is limited by a few factors.

Every region has different regulations when it comes to transmitter power. Although the Ocusync 3.0 and the DJI remote controller hardware are technically capable of producing strong enough signals to cover a radius of 12 km, not all countries and regions permit that.

Due to this, the DJI has different models and certifications for each region. The certifications are usually notified on each drone & remote controller and the transmitting power is locked in the firmware.

The 4 most famous certifications are below along with their max allowed transmitter ranges.

FCC: If your drone is marked FCC at the bottom sticker, that means it is designed to be used in the United States, Australia, Canada, Hong Kong, Taiwan, Chile, Colombia, Puerto Rico, and other regions that follow FCC certification. In these drone models, there is no lock on the maximum range and you are allowed to utilize the 12 km range of your drone (if other conditions are satisfactory like no signal interference and no obstacles)

CE: If your drone is marked CE, that means it is meant to be used in the UK, Russia, France, Germany, Portugal, Spain, Switzerland, Macau, New Zealand, UAE, and other regions that follow CE certification. The maximum allowed range under CE certification is 8 km.

MIC: This certification is for use within Japan only. The maximum allowed transmission range under MIC certification is 8 km.

SRRC: This certification is for use within Mainland China. The maximum allowed transmission range under SRRC certification is 8 km.

Certification TypeMax Allowed Range
FCC12 km
CE8 km
SRRC8 km
MIC8 km
DJI Mini 3 Pro maximum transmission distance in unobstructed interference-free area

Drones shipped to the EU and North America usually have both CE and FCC certifications at the bottom sticker.

The drone will switch to the appropriate certification rules based on your GPS location.

Some people use GPS location spoofing to fool the drone into thinking it is flying in an FCC area while in actuality it is in a CE area (not recommended though)

To check if your drone is operating under FCC or CE, you can go into your DJI Fly App (tap 3 dots >> transmission) and see how many double-digit channels are there.

  • If you see 11 channels, you are on FCC.
  • If you see 13 channels, you are on CE.

Interference & obstacles limit

Even if you are allowed by law to fully utilize the 12 km range offered by the Ocusync 3.0, there are always interferences and obstacles that reduce the effective range.

In urban areas where there are a lot of cell towers, home, and office WiFi, and other interfering signals, the range is considerably reduced.

The range is further reduced if you are flying from behind the obstacles like skyscrapers and towers where you have no direct line of sight.

As per DJI, here is how the effective range is reduced in different environments.

  • Urban areas – strong interference, limited line of sight = 1.5 – 3 km
  • Suburban areas – medium interference, open line of sight = 3 – 7 km
  • Rural areas – very low interference, open line of sight = 7 – 12 km

Battery Range

When talking about ranges, they usually talk about transmitter range and remote control signal strength. They usually ignore battery range limits.

In fact, even if you are in a fully open area with no signal interference and no legal limits, the DJI Mini 3 Pro range can barely reach the 12 km mark. You will consume half your battery before that and will have to return home or risk a crash.

If you have been flying DJI for a while, you might have noticed that the drone always prompts for Return To Home (RTH) mode as soon as the battery is half consumed.

At this point, if you don’t initiate an RTH, you risk losing your drone due to a low battery on your way back.

The Mini 3 Pro comes with two types of batteries:

  • Intelligent Flight Battery: It has a capacity of 2453 mAH and offers 34 minutes of flight time. It can fly your drone for 18 km of distance at a 43 km/h speed. That means you can cover 9 km before you have to return home.
  • Intelligent Flight Battery Plus: It is a slightly bigger version with 3850 mAh capacity and offers 47 minutes of flight time. It can fly your drone for 25 km which means you can cover 12 km before you have to hit the RTH button.

Of course, all these numbers are theoretical and recorded by DJI under ideal conditions. Actual conditions can produce very different results.

In summary, although the remote is powerful enough to control the drone at a distance of 12 km, the battery is barely big enough to get you safely back to your home point.

DJI Mini 3 Pro poor range issue

As with a lot of consumer products, the advertised specification are rarely accurate in the real world. This is not unexpected BUT the DJI Mini 3 Pro has been getting negative reviews from initial testers and pilots around the EU and US when it comes to range.

Some pilots have experienced the drone is losing signal after going a few hundred meters from the controller. A lot of people have been complaining about the poor range of DJI Mini 3 Pro.

In the below video, Henrick from Tech Drone Media tested the new DJI Mini 3 Pro in an open airfield without any interference and was only able to get a range of 2 km only. You can watch the video below

A lot of other people are complaining in the forums and Reddit subs about the poor range and it begs the question – what is going on with the new drone despite all the promises and shiny specs?

One answer could be unfinished firmware.

DJI was under a lot of pressure to release the Mini 3 Pro because Autel had released its mini drone – the Autel Nano Plus and similarly Hubsan was taking the market shares with its Zino Mini Pro.

So, it might be that DJI released yet another unfinished firmware. If this is the case, it’s not all bad as DJI can release a firmware update in the coming days and fix the range issues.

However, if the fault is in the hardware of either the drone or the remote controller, that can be a real issue. A product recall might be in order if that’s the case.

Since it’s a new product a lot of public testings are in order to really know the extent of the range issue. DJI has no official response to all the public board messages yet.

Before you can bash DJI for a faulty product, it’s important to know a few common reasons for poor range. You might get a poor range if:

  • You are flying the CE version and the range is limited by the firmware lock. If you are not in an area where CE is applicable but your drone is still going into CE mode, you can use GPS spoofing or try using a moded fly app (these are grey areas so I am not going to link to the resources here. Try at your own risk)
  • You are flying in a heavily populated area where interference from other wireless sources is interfering with your remote controller. This is the most common cause of lower than advertised range.
  • You are flying from behind an obstacle and there is no clear line of sight. Especially in urban areas, where the more popular bandwidth i-e 2.4Ghz is overcrowded, your remote will try to shift to 5.8Ghz. Higher frequencies are even more susceptible to physical obstacles and hence will cause a lower range.
  • Your antenna is not correctly positioned. Remember the rule of thumb: never point the tip of your antenna towards the drone. Keep them perpendicular at all times for best performance.

Even after taking care of all the points above you still cannot reach DJI Mini 3 Pro max distance, maybe it’s the issue we discussed above. In that case, let’s wait for DJI to come out with an explanation.

  1. Recently I’ve read that about 47% of Mini 3 Pro user Reporting Drop-Outs or Forced Retuns to Home at <= 1KM.

    About 3 days ago DJI said my Mini 3 Pro had Shipped — Not allowing a Refund on the Product. It's going on the 4th day and UPS assures me that they Never received the Product. In other Words, DJI is Lying to Customers in order to Stop last minute refunds on a Defective Product.

    That is my Opinion only … based on the Facts.

  2. Basing my own observations on a wide viewing of subject related video posts, as well as on my own experience with a related issue that has started to occur with a Mavic 2 Zoom, I have noticed that the signal drops/dropouts appear in the main to be occurring with the ocusync in the 2.4ghz TX band. The older O2 (Mavic 2 series) also seems to be showing an increase in interference on this band in particular. These signal attenuations I have noticed as common occurrences with the Mini 3 are identical to the ones I am experiencing and in my own case: have nothing to do with overloaded urban WiFi environments as I mainly fly in isolated rural landscapes within VLOS and maintaining unobstructed TX-drone line of sight. Curiously enough, they only really started to become apparent after the 1.00.0770 Mav. 2 firmware upgrade. The previous firmware (1.00.0670) actually increased the transmitter power, which should have guaranteed a stronger and more reliable control link. I am wondering if in both cases: the problem does indeed lie within conflicting/unrefined firmware.
