I was struggling with having over 500gb used of 1TB with over 300gb dedicated to "Other"
Initially, I had 200gb worth of videos that I offloaded, then removed from the deleted folder. Seems that the needle didn't move much and for nearly a day, it stated I had 85gb worth of videos left.
After seeing the alarm comment with 35gb of data, it hit me.
I was using FilmIC Pro to record some of my videos because it has a "pause" feature which is really nice. I do have it set to save to my photos album, but FilmIc uses a system folder (maybe because it is hidden) to record the video before it transfers over to Photos. FilmIC can also be setup to not sent anything to the photos album. It has its own camera roll. So, it is a matter of choice. I choose for it to go to the photos folder so that I can see it immediately.
So why didn't FilmIc clear the cache I wondered. I rebooted the phone earlier and it didn't work. So then, I opened up the photos app, looked to ensure nothing was in deleted folder, then swiped up to close the program. Then I saw the space Photos used drop from 85gb to 6.8gb.
Okay, good!
So then I went to FilmIC Pro and looked to see if there were any videos that the app was hanging on to. Yep, there was ONE 9-second clip. Once I deleted that 9 second clip and made sure nothing was in FimIC Pro's camera roll, I exited the program and checked and wow, the storage got cleaned up!
No more issues!
It just goes to show that even with 1TB of storage on the phone, that it can be possible for an app to go rogue and start eating up the space if not managed. Apple provides us the tools but when an App utilizes a system folder and not the "App" data area, then it doesn't report correctly. I will continue to use FilmIC Pro. Just have to watch out.
Oh, and another thing that really ate up my space (which actually did reflect in the app) was podcasts. I can't find an overall setting to NOT download podcast content. I see it for each individual podcast so now I am concerned about my other devices!
Update after posting this - I found in the settings where I can prevent downloads of ALL podcasts that I follow. This will help a lot!
I am having the same problem. I don't understand the “system data” took 60.85 GB In my iPhone. Total GB I HAVE 128
I AM LITERALLY LEFT WITH NOTHING.
If anyone finds a solution, share it with me
Same problem here, and just got off chatting with the useless Apple chat support executives. Idiots wasted my time and just suggested to do factory reset followed by backup!! On my iphone, it happened because I was trying to send large files by maildrop. I was trying to send 500+ pics/videos, having size of about 3.5 GB using email/mail drop. I tried 3-4 times, and Every time the process failed it kept keeping that much space blocked!! So after 3 attempts I got left with 0 space and about 13 GB of data showing in “Other System Data”! And that, after I deleted so many apps, files, to make way for more space!! Basically, Apple keeps storing the deleted file in cache, and doesn’t even allow us to delete those!! Btw, I already tried the usual suggestions, and they all fail- clearing safari cache, disconnecting mail accounts, etc etc. Nothing works, and I don’t want to go for Facroey reset. What a ****** situation!
I was in the same situation but I found out that restarting your phone helps reduce the amount of storage taken up by the system data. To restart your phone you need to go to settings and when you get to setting scroll and press general. Then scroll again and you will see an option that says ‘shut down’ in blue. Click that and your phone will restart. This doesn’t get rid of any of the data on your phone just the stuff that isn’t needed. Your phone will go black (how it looks when it is turned off) then hold on the power button until you see the apple logo on your screen. Now wait for your phone to fully turn on and check if it helped
