iPhone 18 Pro iCloud backup size is much larger than expected

Hi everyone,


I recently upgraded from iPhone 13 to iPhone 18 Pro, and I’ve noticed something unusual with my iCloud device backup.


My previous iPhone 13 backup was approximately 5 GB, whereas my new iPhone 18 Pro backup is showing 63.44 GB.



What I find strange is that I am using practically the same apps on both devices and the apps are already sorted by their size in descending order, with max size consumed by Files followed by Whatsapp.


My Photos library is NOT included in this device backup, as it is already backed up through iCloud Photos.


Even after accounting for all the listed apps, I cannot understand where the remaining 60+ GB is coming from.


I’d appreciate insights from anyone who has experienced something similar, particularly after upgrading to a new iPhone.


Thanks!

On your iPhone, open Settings > General > iPhone Storage - how much storage is being used on the phone? You'll be able to see what is using the most space, by app as well as iOS and System Data. I agree your backup size seems out of line. But we can't see what you may have on your iPhone

iCloud storage usage depends on several factors, including whether the user is part of an iCloud Family Sharing plan, the number of devices linked to the account, and the amount of data stored in iCloud Drive. A screenshot showing only the Backups section does not provide the complete picture, as it represents just one component of overall iCloud storage usage. To accurately assess what is consuming storage, a view of the full iCloud Storage breakdown is required.

I am not sharing it with anyone. The screenshot I shared shows how much space my device is consuming in iCloud, which is far more than my previous device.
