When you check for the storage space taken by the apps on your device, you may be surprised to find something called “Documents and Data” taking up a lot of storage space on your iPhone or iPad. In some cases the storage space taken up by “Documents and Data” ends up being greater than the actual app itself.
Let us first take a brief look at what this mysterious “Documents and Data” is, next you will find the steps to delete “Documents and Data” to free up storage space on your iPhone or iPad.
What is “Documents and Data”
Each app on your iPhone stores things like app caches, sign-in info, message history and app related attachments. All this information is labeled as “Documents and Data” on your iPhone.
Over a period of time all this information ends up taking up storage space on your device and it is not uncommon to see the “Documents and Data” taking up more storage space than the app itself.
For example, the SNAPCHAT app on our device has a size of 60 MB, but its “Documents and Data” is taking up 343 MB of space (See image below)
Delete “Documents and Data” on iPhone and iPad
One quick way of clearing “Documents and Data” on your device is to simply delete the app and re-install it back.
1. Tap on Settings
2. Tap on General > Storage & iCloud Usage.
3. Next, tap on Manage Storage option, located underneath sub-heading Storage.
Once you tap on Manage Storage, you will see the next screen where you will see a list of all apps on your device and the amount of storage space taken up by each app.
4. From the list of Apps, tap on the app that is taking up more storage space. In our case, we found the SNAPCHAT app taking up way more storage space than the app itself (See image below).
5. Next, tap on Delete App from the bottom of your screen (See image below).
6. You will see a pop-up menu, tap on the Delete App option
7. Once the app is deleted, open App Store on your device and search for the deleted app.
8. Next, download the app back on your device.
Once the app is reinstalled, check the storage space taken up by this app. You will see that the storage space taken up by this app has reduced significantly. For us it went down from 343 MB to 24 MB.
The remaining 24 MB is most likely Sign-in info which the app needs to keep you continuously signed into the app.
Similarly, you can identify other apps taking up much storage space on your device and repeat the steps above to clear the space taken by “Documents and Data” related to these apps.
Note: This method is not applicable for Stock Apple apps like Mail, Messages, Music and Safari. In the case of stock apps you will need to go into each of these apps individually and delete the accumulated data for each of these stock apps.
