Uninstalled apps using cellular data in iOS

Hi I have the same issue since fall (2023) when I updated to ios17.

I have reset the data usage several times. I even erased the iphone by reseting it to the manufacturer setting. From scratch with no app installed, uninstalled app showed data usage. I reinstalled the few apps that I use. I monitor the data usage everyday and I have unistalled app data usage everyday even if I have not uninstalled apps. I tried the lockdown mode with no success. I disconnected from IClound with no success. I reinstalled the native apps (journal, homekit, etc) with no success. I can't see in the privacy tab any connection other than the legitimate ones. My big questions are: what are those ko sent, where are they going and how to stop that?

Please don't answer that it's uninstalled apps that I removed and I need to reset the data usage because it's not. I wiped the Iphone and reseted the data usage almost everyday.

I am having the same issue after updating to iOS 17.4/17.4.1 I did the same as you, factory reset...

And every day uninstalled apps increase about 15-30KB.

I‘m having the same. I reset the statistics, I did not uninstall any app and there is allegedly data used by “uninstalled apps”. There is even roaming data albeit I was not abroad since the reset. Either something has been hacked, or all this technology does not work as it should

Anyone has the same issue?

Read above. I have factory reset phone, reset statistics, and not installed any new apps after factory reset. Yet uninstalled data appears and grows each day. iPhone 15 Pro Max 17.4.1. Who or what could be using this data?

Well, 17.5 didn’t fix it. Still have the problem!

Update. About a month ago I contacted Apple service and they ran some diagnostic tests. Luckily during these tests, the uninstalled apps data raised. Then, a week later, the gentleman called me back the issue that was transferred to the engineers. He did mention that it was not a security issue but couldn’t tell more. I hope the 17.5 new release will take care of that.

Well, it didn’t. Not for me anyway. There are numerous issues I am finding on my iPhone. One is this…

This is not a data leak issue. Uninstalled Apps is a category to track the data usage of apps that you have delted from your iPhone that have used cellular data. For example, if I have ToDoist, it syncs something to iCloud over cellular data, then I uninstall it, it becomes part of the Uninstalled Apps category of my cellular data usage metric.
