You cannot delete the photos from your iPhone after syncing them to iCloud. All your photos will be gone.
The difference between iCloud and iPhone storage for photos:
Storage Options for Your Photos:
- iCloud Storage:
- Pros:
- Stores original resolution photos in the cloud.
- Access your photos and videos from any device with an internet connection.
- Frees up space on your iPhone.
- Cons:
- Requires an internet connection to access original photos on your iPhone.
- May incur additional storage fees if you exceed the free 5GB limit.
- iPhone Storage:
- Pros:
- No internet connection is needed to access photos stored on your iPhone.
- Free storage up to the capacity of your device.
- Cons:
- Stores lower resolution versions of photos to save space, reducing quality.
- Limited storage space on your iPhone can fill up quickly, especially with high-resolution photos.
Additional Option:
- Optimize iPhone Storage: You can choose to store full-resolution photos in iCloud while keeping smaller, space-saving versions on your iPhone. This option allows access to high-quality photos, even offline, without using up all your device storage.
Choosing the Right Option:
The best option for you depends on your priorities and needs. If you value having high-resolution photos readily available on all your devices, even offline, and have a good internet connection, iCloud storage is a good choice. If storage space on your iPhone is a concern and you primarily use photos on your device, storing them on your iPhone might be sufficient. You can also use the "Optimize iPhone Storage" feature for a balance between quality and space efficiency.
