Device storage

[Jaxx]

I’m just curious if you guys/gals are seeing the same as I

It seems like AIDA is the ONLY tool or way of getting the truth out of the iPhone and the remaining local storage remaining. 
 

I have a 512GB 13 Pro Max; settings general and storage shows my phones got well over 300GB open, AIDA shows the opposite, 200 or a bit less open and 300+ used. 

I also have SnapStats, and several other ‘status’ tools all taking information direct from iOS where it seems AIDA’s figured out the way to measure it correctly and for several years now. 
 

I have experimented with filling it and AIDA is correct. iOS and other tools are incorrect

I hate to bring up a several year old comment but you are correct. I’ve owned the AIDA64 premium app for many years now and it’s literally the ONLY iOS/iPadOS utility meant to do what it does that knocks it outta the park with the storage measurement 

 

I expected to see a few hundred replies to your comment but sadly, no one apparently has figured this out. Because it’s egregious. iOS reports I’ve used around 230GB of my 512 on my iPhone 15 Pro Max. Says I’ve got about 265-270 available. (Assuming the OS and system files are using a partition of the 512 for their under the surface tasks etc accounts for those files that take up the rest of the drive). 
Since purchasing AIDA64, I have never known which was right, as I don’t use 512GB on my phone, nor have I maxed out my earlier owned devices. However, the iPhone 14 Pro Max I passed on to my wife was used to shoot some video in ProRes and while it said in settings —> general iPhone storage I had just under 300GB and we were capturing no more than 10-15 minutes of footage. Turned out that my phone was burdened by much more than the 198 reported pre-shoot. At nine minutes, a ‘you’re almost outta storage’ message appears and I had to kill several apps that I could reinstall w/o losing the data to finish the shoot. 
I went back and forth with Apple support about the issue with its very poor way of tracking remaining storage/storage used. I own a few other apps that supposedly offer the same functionality as AIDA, and in a few cases they’re quite good with a flaw in all of them that is not a small issue. Apple should have been doing it correctly all along but they have the ‘uninstall apps unused after a while’ option clicked on, and I think they assume people will keep it there - and I’m sure many do. But many of us don’t and would prefer a new, more real and efficient way of iOS and its calculation of storage remaining. Ad it’s the way they get away with the ridiculous increases in storage costs off the shelf.  I can buy a 4TB external NAND with Thunderbolt for the same price Apple charges the jump from 256-1TB which is significantly more money to upgrade than my T9 4TB. 
It’s tough with the iPad as well because of the discrepancy between the 256/513GB models vs the 1 or 2TB versions getting double (8 vs 26GB) the RAM with the higher priced and more storage models. 
I definitely enjoy having 1 or 2TB on my iPad these days with the size of some apps (25GB+) as well as native apps and how they choose to store their info. Like Notes, photos even Pages and iMovie or God forbid you use FCP/Logic on your iPad (I use both and DaVinci) - and you can hear the storage being sucked away!

Its very cool the Pro models are now able to use the faster external SSDs via the Thunderbolt port (USB C) for editing and storing - exporting to and saving to the external drive instead of the internal. As even small projects can take up a couple hundred GBs of data easily when shot in LOG ProRes and ProRaw files or .wav/uncompressed audio. 

Any idea why Apple has ignored this issue since its birth? It’s quite surprising when an app won’t download because “you are out of storage. Please remove apps or data to install this app”  dialogue box pops up.
