iCloud + storage
I purchased an additional 50 GB of storage to be able to backup my iPhone to transfer everything to a new iPhone. Once the transfer was made it now says I have used 49.3 GB of the 50 GB of which the backup takes up the most. Do I have to keep that backup And do I have to keep the additional 50 GB of storage or will my backups just contain the differences moving forward? I have a 14 pro max with 250 GB of storage.
