Issue For Backup and System Data Size Abnormal


Hello, so i recently just updated my iPhone 12 Pro to the latest ios 27 and had several’s issues. First issue is, my system data size is (what i think) abnormal at 99,59gb. I tried all the tricks on this community forum and not single one worked, and second is i couldn’t backup my iphone into icloud or using itunes, even tho i got enough storage to backup it just wouldn’t work. When i tried to backup using iCloud it’s just always failed and i have tried it several times, when i use itunes on my laptop it has the same issue and my laptop just suddenly freeze when i tried to enter the encryption backup password. And the issue is happening too when i try to backup my whatsapp data, here is the screenshot of the failed backup that i get after trying several times. Does anyone have a solution for this kind of problem? It would help if anyone got the solution.

And what happens when you connect to a strong wifi and then back up to the cloud?

You will need twice the amount of iCloud storage as the total size of the phone storage.

Eg 128GB phone needs the 200GB plan. Etc

Until you get the backups sorted out you cannot get the system storage down to nearer 10GB by restoring the phone to factory and restoring the backups on setting up again

I haven't even seen a PC for 20 years.

You can't have what you won't pay for.

It show’s the same error for the backup
