There certainly are DJI drones that will have better distances, I am not familiar with all the different models that DJI has to offer but I personally opted for the
DJI Mini 2. That model doesn't even use "wifi" (and likely has a much better range than using wifi), it uses "OcuSync 2.0". Ocusync 2.0 has a purported (max) range of 10km. Of course in reality you'd quite possibly be lucky to get 8km, but either way; I am sure it will likely go (work) a lot farther than WiFi will...
Battery life is very common to be somewhere between X-31 minutes ("listed")... Going back to the
DJI Mini 2 that I chose, it has a "listed spec" flight time (max) of 31 minutes... It does seem this unit can actually attain that too, although you have to bear in mind, any machine/drone is going to suffer a reduction in flight time if it's inclement conditions, such as wind... Not to mention other factors like how fast you move around, ascend/descend etc... I'm almost sure you could put the
mini 2 into "cinema" mode and fly around slow and not perform much altitude changes and actually see the full 31 minutes... On the other hand you could put it in sport mode and probably burn the battery out in 1/2 that time!
All that being said, I have to "chime in" (add) with a few important details, just in case you did not know / weren't aware... Firstly, to fly recreation-ally you must
take the TRUST test (and carry that document with you whenever you fly)... I personally recommend getting it through the
Pilot Institute... It is completely free, and done entirely online, and only takes about half of one hour. IIRC you only have to provide your name and an email address (no physical address required)... But this will cover all of the "ultimate basics", like TFR, VLOS, LAANC, 400' limit, uncontrolled/controlled airspace etc... It should also cover the next few aspects I'm about to get in to. To fly for recreation: if your drone is <250 grams - you will *not* need to register. If your drone is >250 grams, you *will* need to register. Also, you don't actually individually register each and every drone you own, you are basically registering yourself, to fly pretty much any drone you desire for recreation, between 0-55 lbs. Registration is $5 for 3 years. That being said, there is a CLEAR distinction for "recreation", and there really is NO "grey area"... Either you are "flying for fun" or you're not... If you *are* flying for fun, then that is "recreation"... If you are *NOT* flying for fun, then you are NOT flying for recreation and will require a Part 107/commercial license (has nothing to do with "for monetary gain")... You can surely study for this completely on your own, and take the test (I think it's $150)... Though I would also (again) recommend
@pilotinstitute for their preparation courses for the Part 107 (I have not personally taken it but I hear it's "top notch"). ALL drones used under Part 107 MUST be registered (there's no 250 gram "cut-off" like there is for "recreation")! They (however) must be individually registered @ $5 / 3 years.
So, your intent as you describe it ("we want to use it to take videos for our online advertising. We run outdoor tours and want to make overhead videos of our tour groups"), would certainly be a Part 107 use by the way...
At any rate, another good "starting point" is this following link :
