New iPhone 14 Pro 1TB - storage filling up fast

Hello Starbreeze,

Welcome to Apple Support Communities, and congratulations on your new iPhone 14 Pro! We understand your concern with this behavior, and we'd be happy to get pointed in the right direction to get some help. In this specific situation, we'd recommend working with our support teams to work with you towards a resolution. Please get in touch with them using this link: Apple Support

We hope this information is useful. Kind regards.

I have this exact same issue. It seems to only affect people who have upgraded from iPhone 11 Pro to iPhone 14 pro.

The general consensus, from searches I’ve done, is that the only fix is to wipe it and start again as though it was a new phone, but don’t restore your old backup. I’ve resisted doing this so far because it’s a real pain to set all my apps up again. I think I might have to do it at some point though.

I have the identical issue, but I upgraded from an iPhone 13 Pro Max to an iPhone 14 pro max. Went on cellular data sitting nicely of 140 gigs storage on my phone, but as soon as I had to Wi-Fi in jumps up to one terabyte. I am really not willing to start with a new phone. The reason I stay with Apple is to prevent the need to do that and ultimately, if I was being told that was the only solution I’ve been more willing to move to a different brand. I’m really looking for a workaround, so I’d be grateful if an apple member of staff could advise

I have the same issue, but I went from iPhone 13 Pro to the 14 Pro. Support was going to have me do the full wipe and everything, but I didn’t want to do that. As someone else mentioned, the issue is resolved when I restart the phone and disconnect the Wi-Fi. I just upgraded to iOS 16.1 and hoped the issue would be fixed, but System Data started filling up within 5 min of the upgrade. Back to cellular data I guess.

Have you found a work around for this? I have the same problem and I did the exact upgrade from an iPhone 11 Pro to 14 pro.

IMO it is an errant process writing an error log. The phone fills up whether I am on WiFi or a data network.

I spent an hour on the line with Apple support by phone and apart from leaving it on Wi-Fi for a few days. They have no better idea. That was going to finish compiling and clear. It’s been four days and it hasn’t worked. I’m going to ring them tomorrow

Definitely seems to be a 11 pro to 14 pro issue. Mine’s doing the exact same. Fine for a few minutes after a restart. Then system data fills up to full.

I’ve updated to 16.1 and the issue seems to have cleared itself. If it comes back I’ll post here, but for now it all seems good.

I think you’re right, after updating I’m up a little higher on System Data but it seems to be stable.
