Capacity problem

Hi valentijnV19

Welcome to the Apple Community.

Wondering which iOS is installed on you iPhone ...

.... you may want to update to the latest version (15.4.1) when space permits.

Re: Capacity problem:

There are lots of options: Apple support have articles online (links below) to help with storage:

All the best :-)

My Dutch is pretty bad, but I believe the big item there is it saying "Calculating......." But that's likely to be a combination of system data and "other". You might check in Settings > General > iPhone Storage (or the equivalent in your language) and see what that says as it's a little bit different than on a Mac or PC.

Not sure exactly what "other" or excessive system data is, but some believe that much of it might be corrupted or other files that are just garbage. Not sure why, but they're not cleared regularly and can build up (I've got a 32 GB iPhone and it can be a real problem). The only way I've ever been able to deal with it was to make a backup to a computer (looks like it's never been done on yours), erase the iPhone to factory condition (it might be faster to do it from the iPhone and not from a computer), and then restore the iPhone from the backup. That always clears quite a bit, although it will typically fill up again.

Hey there, ValentijnV19.

I am William, and I am here to solve your problem.

Seems like you have been using your iPhone for a long time and you have been heavily using it, causing a lot of cache to block your storage. Cache is data that is recorded to improve experience. I personally think that this is a result of overloading cache.

A solution I recommend is to:

1. Back up all the data from your iPhone to either your Mac or iCloud.
2. Go to Settings/About/Reset/Erase All Content and Settings and press Erase.
3. After your iPhone is totally erased, plug it in to your Mac or connect to iCloud to bring all data back. No data will be lost, and all cache will be cleared.

(No worries, if you backed up on iCloud, your iPhone will automatically find your backup and restore it)

Hope this helps.

Sincerely,

William

I have the same problem (iPhone XR, 64Gb, iOS 15.4.1) - SystemMemory /Cache fills up until the limit is reached.

Note! I DID a complete restore and backup 2 weeks ago - worked fine for 10 days, now the "systemdata" again is >23Gb large and the available memory capacity is almost zero!

This must be an issue of the iOS (latest version!) or of a specific app - many users report this problem!

If there's something "bleeding" it's really just more like giving it a blood transfusion and trying to keep up with it.

However, I've seen this sort of thing as far back as my iPhone 4S. It just collects garbage that can't be manually cleared (cache can be cleared) and then it might run against the limit. I've seen that it will usually clear enough that it won't crash the system, but doesn't seem to clear the bulk of it. But it's a temporary fix to restore from a backup.
