How Could My iPhone Use 9GB in Just 7 Minutes?

It's probably not a hack. Most likely, your phone was doing something like a software update in the background or an app misreporting its usage. As long as you're on the latest iOS, it’s pretty secure against hacking attempts. Check your mobile data settings to see which apps are pulling data— that might give you a clue!

Thanks for sharing your thoughts! Here's what I looked into: only TikTok was active during that time, and my total data usage for this cycle is 50GB, so it seems unlikely that it's the cause. My internet provider confirmed specific entries at exactly 60MB for those 7 minutes. I also checked for OS updates and fresh installs—none were found. Any ideas on what else I might check?

Your phone could have been backing up to the cloud without you realizing it. iPhones can do that in the background, especially if you're connected to Wi-Fi at some point. Just to be safe, check your backup settings. It might not be a hack, just a regular update procedure.

Sounds like a misbehaving app to me. iPhones can sometimes act up and report data usage inaccurately. Have a look in your settings under mobile data to see which apps have been using the most data. You might find the culprit there.
