Push Notrifications generates lots of traffic

Yes jgmartins, I solved the problem for my iPhone but my solution is a bit extreme. I changed wireless carriers. Moved from AT&T to T-Mobile and the problem stopped. (I also got a better plan with unlimited data & better price.)

Before I made the move, I talked with four different AT&T reps (including a "supervisor") who each gave me a different story on the issue from their side. Three promised to send out a firmware update that would fix the issue. I waited for 3 days but nothing arrived. The fourth one said "Oh no, we don't send out software updates. Those come from Apple." Their customer service was disappointing, to say the least. I talked with Apple Support who confirmed all the settings on my iPhone were good and there wasn't anything they could see from the Apple side that would be causing the issue. I did the factory reset, etc. All the solutions previously recommended. Nothing worked so I had to keep Cellular turned off.

After switching to the T-Mobile service, the issue disappeared. Can't explain it. Just know that it worked for me. Good luck with yours! It's certainly an annoying issue.

jgmartins,

Since that persisted after following those steps, you'll want to reach back out to Apple Support: Contact - Official Apple Support They'd be in the best position to continue troubleshooting that behavior.

Take care.

I am having same problem on two iPhone 12 pro maxes, an iPad Pro, and an iPad Pro second generation. I am using AT&T in St. Louis, Missouri. Problem started after installing iOS 15.6.1 and updating my apps. I am getting as much as 3.5 GB per day of "Settings > Cellular> System Services> Push Notifications", and my (otherwise healthy) battery requires unusually frequent recharging. I turned off all app Notifications (except Phone and Messages), and all background app refresh. Also, at Apple Support's suggestion, in Privacy>Location Services>System Services, I turned off several location related System Services (such as Location Based Alerts). This has not worked to stop the Push Notification data hemorrhage. Phone calls to Apple Support on 8/21/22 and 8/22/22 also failed to solve the problem. So far, the only way to stop the Push Notifications is to turn off Cellular Data. Even after stopping Cellular Data, I have noticed unusually rapid battery depletion if Wi-Fi is turned on.

Hi jgmartins,

If this is still an issue, we'd advise contacting Apple Support directly for assistance. See contact options here: Apple Support

Cheers!

I have exactly the same problem (you described it very well). And it all started with iOS 15.6.1.
