DJI Mini 5 Pro vs DJI Mini 3: which one should you buy?
Three years and two generations separate these two. The odd thing is that the older drone still holds the longest flight time of any sub-250 gram DJI drone, and it is the only line it wins.
Written by Peter Leslie, GVC-qualified commercial drone pilot | Every figure checked against both DJI manuals | 3 Aug 2026 My short answer
I recommend the DJI Mini 5 Pro
DJI Mini 5 Pro
The 2025 flagship mini
A one-inch sensor, LiDAR and 42 GB of storage. The Mini 3 answers with two extra minutes in the air, and very little else.
- One-inch, 50 MP sensor against 1/1.3-inch, 48 MP
- LiDAR and omnidirectional vision against downward only
- 4K at 120fps against 4K at 30
- 42 GB inside against no storage at all
- O4+ against O2 transmission
- 36 minutes against the Mini 3’s 38
I recommend this if…
- The finished footage is the reason you are buying
- You will fly near obstacles on more than one side
- You want slow motion and a sharp live view
- You would rather not buy a memory card
If flight time and price come first
DJI Mini 3
The 2022 camera mini
The longest-flying drone in the class, and three years behind on everything else. Still a good camera, with no safety net at all.
- 1/1.3-inch, 48 MP against a one-inch, 50 MP sensor
- Downward vision only — nothing forwards
- 4K capped at 30fps, no slow motion
- No internal storage at all
- O2 transmission, two generations behind
- 38 minutes, the longest in the class
I recommend this if…
- You want the longest flights of any mini
- You fly in open space with little to hit
- Price is a significant factor
- You want two grams more margin under the limit

Where each of these sits in the range
The Mini 3 arrived in December 2022 as the sensible middle of DJI’s small folding line. The Mini 5 Pro is the current flagship of it.
Both fold, both need a controller and a phone, both carry a C0 class mark and both sit just under 250 grams.
So this is a straight generational comparison, which usually means the newer drone wins everything. Here it wins everything except one number.
That number is flight time, and the Mini 3 still holds the class record for it at 38 minutes.
Both appear in my best drones under 250g guide.
Four things that do not separate them
Clear these away first.
-
Same three-axis gimbal
Tilt, roll and pan on both.
-
Same C0 class mark
And the same Flyer ID and Operator ID.
-
Same cold limit
Both rated down to minus ten degrees.
-
Both fold
And both need a controller and a phone.
-
So ignore all 4
None of it can tell you which to buy. The next four things can.
Both also fly on bare propellers with no guards fitted as standard, and neither can be launched from your palm.
The four differences that actually matter
1. The Mini 5 Pro has a one-inch sensor. The Mini 3 has 1/1.3-inch
The megapixel counts are close, at 50 against 48, and that is the misleading part.
What matters is physical area, and a one-inch sensor has substantially more of it than a 1/1.3-inch one.
Mini 5 Pro
50MP
one-inch sensor, f/1.8
Mini 3
48MP
1/1.3-inch sensor, f/1.7
More sensor area means cleaner footage as the light drops, and more room to crop or grade before the picture breaks up.
The Mini 3 has a very slightly wider lens, at f/1.7 against f/1.8, which is the one camera line it wins and it does not offset the sensor.
Stills go from 8064 by 6048 to 8192 by 6144, which is a modest jump on paper and a larger one in practice because of where the pixels are gathered.
Winner — DJI Mini 5 Pro
A physically larger sensor gathering more light, from the same nominal resolution. The Mini 3 is a good camera drone; the Mini 5 Pro is a better one, and the gap widens as the light falls.
In bright, still conditions the two are closer than the specifications suggest, because 48 and 50 megapixels resolve similar detail.
Check the Mini 5 Pro on Amazon2. The Mini 5 Pro sees in every direction and adds LiDAR. The Mini 3 sees the ground
With three years between them, this is where the gap is widest in practical terms.
The Mini 3 has a downward vision system. It helps the drone hover and land, and it does nothing about what is ahead.
The Mini 5 Pro has omnidirectional binocular vision, which is paired cameras judging depth in every direction, plus forward LiDAR and infrared underneath.
Mini 5 Pro
Omnidirectional vision plus LiDAR
- Paired cameras judging depth all round
- Forward-facing LiDAR as well
- Infrared underneath
- Brakes or steers round what it sees
Mini 3
Downward vision only
- Knows its height above the ground
- Nothing facing forwards
- Nothing watching sideways
- You are the collision avoidance
Both fly on bare propellers, so on the Mini 3 a misjudged branch is a repair rather than a bump.
The Mini 5 Pro is also rated to more wind, at 12 metres per second against 10.7, which is roughly 27 miles an hour against 24.
Winner — DJI Mini 5 Pro
The most complete sensing package DJI fits under 250 grams, against a system that only looks down. For orbits and follow shots near anything solid, that is the difference that matters most.
In genuinely open space the Mini 3’s missing sensors never come up, and you keep two extra minutes of flight.
Check the Mini 5 Pro on Amazon3. The Mini 3 still flies longer, by two minutes
The one line the older drone wins, and it is worth stating plainly because it is genuinely surprising.
DJI rates the Mini 3 at 38 minutes on its standard battery. The Mini 5 Pro is rated at 36.
Mini 5 Pro
36min
about 26 in reality
Mini 3
38min
about 28 in reality
Two minutes is a narrow margin and both figures are laboratory numbers measured in still air, so in practice the difference is smaller again.
Both offer Plus batteries with much longer quoted figures, and on both those batteries take the drone out of the sub-250 gram bracket.
On the Mini 5 Pro the Plus configuration is the C1 model at 355 grams, quoted at 52 minutes. On the Mini 3 the Plus battery pushes past 249 grams for a quoted 51.
Winner — DJI Mini 3
Two extra minutes, and the Mini 3 holds the longest standard flight time of any sub-250 gram DJI drone. It is a small win but it is a real one, and it is the only line here that goes this way.
Two minutes is well inside the margin that wind and temperature will take off both drones anyway.
Check the Mini 3 on Amazon4. The Mini 5 Pro holds 42 GB and shoots slow motion. The Mini 3 does neither
Two differences that both change what the drone can do on the day.
The Mini 3 has no internal storage at all, so a microSD card is compulsory from the first flight. The Mini 5 Pro has 42 GB built in.
Mini 5 Pro
42GB
fly all day, no card needed
Mini 3
0GB
a card is compulsory
Frame rate is the other half. The Mini 5 Pro records 4K at up to 120 frames a second where the Mini 3 caps at 30, which is normal speed only.
So slow motion is simply unavailable on the Mini 3, at any resolution worth keeping.
Transmission runs the same way, with O4+ against O2. Neither quoted range matters in the UK, but the newer link is more robust and gives a sharper picture to compose on.
Winner — DJI Mini 5 Pro
Forty-two gigabytes, proper slow motion and a modern transmission link. None of it is dramatic alone, and together it is the difference between a drone that needs nothing else and one that needs a card before it is useful.
A memory card is cheap, and if you never shoot slow motion the frame-rate gap costs you nothing.
Check the Mini 5 Pro on AmazonFour questions that will tell you which one to buy
Work down them and stop at the first one you can answer firmly. That is your drone.
Is the finished footage the reason you are buying?
Mini 5 ProWill you fly near obstacles on more than one side?
Mini 5 ProDo you want slow motion, or no memory card to buy?
Mini 5 ProIs the absolute longest flight time, or the lower price, the priority?
Mini 3The Mini 5 Pro wins three of four comfortably, and the Mini 3’s win is two minutes. If you already own a Mini 3 and are wondering whether to upgrade, the sensing is the reason to do it rather than the camera. The Mini 5 Pro against the Mini 4 Pro is the closer comparison if you want the middle option.
Two catches worth knowing before you order either one
Neither is a reason to avoid either drone. Both are things I would want to have been told before paying.
The Mini 5 Pro weighs 249.9 g, with a stated tolerance
DJI gives the Mini 5 Pro’s takeoff weight as 249.9 grams, and its own specification page adds that the actual weight is approximately that, plus or minus four grams.
At the top of that band a drone would weigh nearly 254 grams, which is over the line the sub-250 gram claim rests on.
The declared class figure is 249.9 grams and the rules work from the declaration. But the margin is nominal rather than real.
The Mini 3 is 248 grams with no such tolerance stated, which gives it two grams of genuine room. Neither is generous.
Both have Plus batteries that break the limit
The Mini 5 Pro’s 52-minute figure and its 19 metres per second top speed both belong to the Plus battery, which is the C1 model at 355 grams.
The Mini 3’s 51-minute figure needs its own Plus battery, and its manual notes on page 7 that this takes the drone over 249 grams.
So compare 36 against 38, and treat the longer numbers as belonging to heavier drones with different rules.
Ceiling, size and upgrading from a Mini 3
Three points worth knowing before you decide.
Ceiling favours the Mini 5 Pro heavily, at 6000 metres against 4000. Neither figure has any bearing in the UK, where you are held to 120 metres.
The Mini 3 is the smaller package folded, at 148 by 90 by 62 millimetres against 157 by 95 by 68.
If you already own a Mini 3, the honest case for upgrading is the sensing rather than the camera. Your existing footage will not look dated; your near misses will.
Nothing carries over. Batteries, propellers and the controller are all specific to each drone, so an upgrade is a clean replacement rather than an addition.

Both drones need a Flyer ID and an Operator ID. Neither is exempt
You will read all over the internet that drones under 250 grams need no licence. For a camera drone in the UK that is simply wrong, and both of these are camera drones.
Any camera drone between 100 g and 250 g needs both of these before you fly it outdoors. At 249.9 g and 248 g, both sit in that bracket narrowly.
Flyer ID
Proves you know the rules. A free online theory test, valid five years.
Operator ID
Registers you as responsible for the drone. £12.34 a year, and the number must be labelled on the drone.
Neither needs a GVC or an A2 Certificate of Competence for ordinary recreational flying. Both are C0 class marked in standard form, though the Mini 5 Pro is also sold as a C1 model at 355 g. There is more in do I need a licence for a sub-250g drone and UK class marking explained.
Why I pick the DJI Mini 5 Pro over the DJI Mini 3
Three years and two generations apart, and the older drone still holds one record: the longest standard flight time in the class, by two minutes.
Everything else goes to the Mini 5 Pro. A larger sensor, the most complete sensing package in the class, slow motion, 42 gigabytes of storage and a modern link.
If you fly in open space and want maximum airtime for less money, the Mini 3 still makes sense. For anything else, the newer drone is a genuinely different proposition.
My recommendation — DJI Mini 5 Pro
DJI Mini 5 Pro
2025 — 249.9 g in C0 form
I recommend the DJI Mini 5 Pro over the DJI Mini 3 because it is three years newer and every part of the drone shows it, from the one-inch sensor to the LiDAR to the 42 gigabytes of onboard storage. The Mini 3 keeps the longest flight time in the class by two minutes, which is a narrow crown to defend. Everything else here runs the other way. If the budget stretches, the Mini 5 Pro is a substantially better drone.

The endurance option
DJI Mini 3
Buy this instead if flight time and price are what decide it, and you will be flying somewhere open enough that the missing sensors never matter.
