Uploading from iCloud to iPhone storage

Howdy Shaykee,

Thanks for participating in the Apple Support Communities!

With the setting you mentioned, this will allow the original file size to be stored on your iPhone; however, it won't remove photos from iCloud if that's what you're looking to do. Check to make sure you have enough available storage on your iPhone to store all of the photos and videos in iCloud on your device to see if that could be related to what you're seeing.

If you're looking for assistance with seeing all of your photos as opposed to downloading the original size, this can be done without enabling the setting you mentioned as long as you have enough available storage on your iPhone. You'll want to be sure there is enough storage to display the photos and videos. Check out the following resource for additional information on this: Access and view iCloud Photos on your iPhone, iPad, or iPod touch - Apple Support

All of your photos on all of your devices

iCloud Photos works seamlessly with the Photos app to keep your photos and videos securely stored in iCloud and up to date on your iPhone, iPad, iPod touch, Mac, Apple TV, and iCloud.com. For example, let's say you have an iPhone, iPad, and Mac. You can take a photo on your iPhone and see that same photo on your other devices and iCloud.com too.

If you're wanting to download a copy of the photos and videos to your iPhone instead of having them sync through iCloud, check out the following steps instead. Additional information can also be found here: Download iCloud photos and videos - Apple Support

How to download photos and videos from iCloud.com

If you want to save copies of your photos and videos from iCloud.com to your iPhone, iPad, iPod touch, or your Mac or PC, follow these steps.

On your iPhone, iPad, or iPod touch

1. On iCloud.com, tap Photos. 

2. Tap Select, then tap a photo or video. To select multiple photos or videos, tap more than one. To select your entire library, tap Select All.

3. Tap the more button .

4. Choose Download, then tap Download to confirm. 

If your photos download as a ZIP archive, learn how to uncompress the folder on your iPhone, iPad, or iPod touch. 

We hope that information is able to help. If not, provide more details on what you're looking to do as well as what you see occur. Be sure not to provide any personal information, email addresses, or serial numbers as those aren't needed here.

Have a great day!
