From 27th October, my iPhone started using a lot of Wi-Fi Bandwidth and I cant use the Wi-Fi for any other purposes. Things I checked:
- Checked for Whatsapp chat backup, No.
- Checked for Translate offline languages, No.
- Checked for iCloud Backup, No.
- iOS update, No the auto update is off. Currently using iOS14.0.1. Since all bandwidth is used I cant update it manually also. So I didn't try.
- Auto App-Update, checked and it is already Set to Do not auto update over Cellular and Wi-Fi.
After all these steps, still the problem is not solved. So I reset my iPhone deleting every data. Then I restored all data from iTunes Backup and tried to download all app and it took a huge time and lot of data because something is running in background. So I paused some of apps from downloading and then cancelled the download of these big apps like Apple Office Apps, Google Office Apps and MS Office Apps and Garage Band.
Then I deleted all my Apps to check if any app is doing it. First whatsapp and then every other non-apple apps + Watch app and Translate app.
It didn't work.
Now the phone, despite having nothing, is still using all the Wi-Fi bandwidth.
I have never tried with Cellular data since I don't have a Cellular plan and this king of data usage will cost a lot of Money if cellular data is consumed.
Also, now randomly, the phone is getting disabled for 5 minutes, mostly when I press the power button or when I restart the iPhone.
This is not Jailbroken or anything.
**Do anyone experience the same issue, or anyone advice me to solve this problem. ** I would really appreciate it. Thanks in Advance.
Update on 4th Nov
I have already deleted all apps other than Apple apps. Today, I deleted each app of apple and looked. When I delete the contact app, the wifi usage became zero.
Now I am going to do the restore of my iTunes backup and delete the apple apps and see how it goes.
Update 7th Nov Still the same problem of using a lot of Wi-Fi data exists even though all the apple apps are deleted.
