I'm a bit confused about how iCloud functions when it comes to storing photos. When someone snaps a picture on their iPhone, I'm guessing that picture is saved to the phone's internal storage first, right? Then, if iCloud is enabled, it should also automatically back up that photo to the cloud. That seemed straightforward until I got a notification saying my iCloud storage was full, and I noticed that a bunch of my photos were missing when I checked the Photos app later. I didn't find them in the trash either.
Is it possible that those missing photos didn't sync with iCloud, meaning they weren't backed up like I thought? I've experienced moments when my signal was weak, and photos showed up as low-res until they fully downloaded, which got me wondering: Are some of those images only stored in iCloud and not on my phone? Subsequently, I opted for iCloud+ to get 50 GB more storage, but that hasn't resolved my issue. I'm just trying to understand better how iCloud operates; it shouldn't feel so complicated for a service that's supposed to back up my data. Any insights into where I might be misunderstanding things?

I feel you on the confusion! It's super annoying that when your iCloud runs out of space, things vanish unexpectedly. Just to clarify, your photos are uploaded straight to iCloud—your phone won't keep duplicates unless you select "Download & Keep Originals". If you run out of iCloud storage, it doesn’t randomly delete files. You just lose the ability to upload new ones. If you want those pictures back, visiting an Apple Store might help; they can sometimes recover data if it's not fully deleted.
Sounds like you might be a bit confused about iCloud. Photos do get uploaded to iCloud when you enable iCloud Photos, but they aren't backed up in the traditional sense. If your iCloud is full and you don't have the space, then new photos can't upload. Make sure your phone isn't also out of internal storage, because that can complicate things too!
iCloud mainly syncs your photos rather than back them up. If you delete something off your phone, it'll also disappear from iCloud after 30 days unless you have a backup somewhere else. It’s better to have a local backup or use a second service like Google Photos for extra safety.

Yeah, it's crucial to keep both your internal storage and iCloud storage balanced. If your iCloud fills up, new photos won't back up, but they might also not sync properly to your device if your phone's storage is tight!
