Hi all,
I searched for an answers but found nothing… I see the DJI Fly app has taken a whopping 6.43GB of space on my phone which seems to be for the flight logs.
Without losing any important flight data, is there any way of thinning this out without any disadvantage to, for example, the renewal of an OA?
In case it’s relelvant, I use my phone to fly a Mini 3 Pro commercially.
I’d be really grateful for any suggestion:-)

Copy your flight logs onto some other storage, like an sd card, memory stick etc, then delete from your phone. I keep mine on a seperate folder on the desktop pc so they’re always there if I need them.

THANK YOU VERY MUCH! Hopefully I won’t come back to you with some stupid question like how to get them off an iphone! I think I’ve found a way …
Many thanks again!
Silly question, but how do you copy the logs in the Fly App from your phone to an SD card…
Depends on the phone model and if it has an sd card slot? If it does then pop in the card and copy it over. If not, then use an otg cable. I prefer to copy straight to the desktop, or I use a sandisk memory stick that has normal usb at one end and usbC at the other

The flight logs shouldn’t be that large
Check in the app under the setting (clear Cache)
Just delete them, DJI has them anyway 
Where are you looking to see 6.43GB of space taken up
Ahh on checking again it was the App cache that had over 9GB. The Flight record cache was only 640MB. I’ve cleared the former. 
Under Settings, General, iphone storage. There it tells the the size of the app and the size of tye “documents and data.”
I cleared the cache but that was only 1.4GB
I know that’s why I asked, so the documents and data are large, not the app
Do you download the photos and videos to the device?
You can delete them from within the app under the album menu
Looks like you have downloaded a video or two on to your phone. Check all folders linked to DJI for unusual amounts of usage.
Dear All, many thanks for all the thoughts and help. I have finally found a file called ‘video cache’ on the iphone which I deleted.
For those interested: Connect iphone to mac >click on the phone in the finder >click the Files tab >choose the DJI Fly app. I erased the Video Cache Folder which had over 4GB of video files for some reason.

Just thought I’d let you know,
You can also delete the cache without plugging in to Mac, by going into the files / folders app on the I phone where you will find the DJI cache & you can delete from there, is what I used to do

Very interesting - thanks so much for that! I hadn’t realised that files is like Explorer (ish!) in Windows.
