My iPhone is running low on storage and keeps recommending that I offload unused apps. I understand that it removes the app but keeps its data, but how useful is it in practice? Is there any risk of losing something, and will I be able to reinstall the apps later without problems?
Yeah, I use it for apps I haven’t touched in months. It basically gets the app itself off your phone while leaving the stored data there, so you can reinstall it later and keep that data. You can do it manually under Settings > General > iPhone Storage. Tap an app and you’ll see the Offload App option. The icon stays on your Home Screen with a little cloud next to it, so you know it was offloaded.
One thing I’d check before doing it is how much space the app is actually using. I had one that was only around 400 MB, but Documents & Data was over 3 GB. Offloading it barely changed my storage 
If the data is the big part, I’d look inside the app for downloaded videos, music, maps, saved media, or other offline stuff. Some apps let you remove that content without removing the app.
One thing that confused me for a while: Remove from Home Screen isn’t the same thing as Offload. If you choose that option, the app just moves to the App Library. It’s still installed, so it doesn’t free up the app’s storage.
And Delete App is different again. That removes the app and its related data from the iPhone. I’d be more careful with that if the app keeps anything locally that you actually need. If it’s something you might want again later, Offload makes more sense if you want to keep its stored data around.
This is already clearing up a few things. I checked two of the apps I was thinking about offloading and, yeah, one of them has way more Documents & Data than the app itself. Also had no idea Remove from Home Screen did literally nothing for storage lol.
There’s an automatic option too if you don’t want to keep doing this manually.
Settings – Apps – App Store -Offload Unused Apps.
With that turned on, iPhone can remove unused apps when you’re low on storage while keeping their data. The icon stays there with the cloud symbol, and you can tap it to download the app again.
I’d also check the Files app if you’re trying to make a noticeable dent in the storage. Old downloads can pile up there, and some apps keep a lot of offline content that doesn’t really need to stay on the phone. For the apps you still use regularly, I’d check their own downloads first rather than offloading them.
I went through iPhone Storage after reading these and found a couple of apps with a ridiculous amount of downloaded stuff. Cleared some old offline files and that freed up more space than offloading a few of the smaller apps. The automatic setting is on now too. Didn’t know iPhone could handle that on its own.
Yeah, if something important is only stored locally in an app, I’d make sure it’s synced or backed up before deleting the app completely.
Good call yoo! I had one app with some stuff I actually needed, so I’ll leave that one alone for now.
