Fix OneDrive Uploading Only One File on iPhone or iPad
Question details
The user is attempting to upload multiple files to OneDrive from an iOS device, but the app only successfully uploads one file from the selected batch.

- Product
- OneDrive
- Device & OS
- iOS (iPhone/iPad)
- Scenario
- Uploading a batch of multiple files or photos to cloud storage via the mobile application.
- Observed behavior
- Only a single file processes and uploads completely, while the rest of the selected files fail to upload or do not trigger the upload sequence at all.
Verify that your iPhone or iPad is connected to a strong, stable Wi-Fi network and ensure you have sufficient storage space available in your OneDrive account before troubleshooting the upload process.
Upload Directly from the OneDrive App in Smaller Batches
Bypassing the native iOS Files app integration and uploading directly from inside the OneDrive app often resolves batch upload glitches.
Sometimes the integration between iOS and third-party cloud applications faces timeout issues when sharing multiple files simultaneously. Using OneDrive's built-in upload feature provides a more stable connection.
Launch the OneDrive app on your iPhone or iPad and navigate to the folder where you want to save the files.
Tap the Add (+) icon located at the top right corner of the screen, then select 'Upload' from the dropdown menu.
Choose 'Files' or 'Photos' depending on your media type, and select a smaller batch of files (e.g., 5 to 10 files) to ensure they process smoothly.

Check iOS Permissions and Background Refresh Settings
Ensure OneDrive has the necessary iOS permissions to access your files and run in the background during uploads.
Use OneDrive Web via Browser as a Workaround
If the mobile application consistently fails, using the web version of OneDrive can act as an immediate temporary fix.
Experience Seamless File Management with WPS Office
If you are frustrated with upload glitches and syncing issues, try WPS Office. As a free, lightweight, and powerful alternative to Microsoft Office, WPS Office offers built-in cloud storage that seamlessly handles batch uploads and syncs perfectly across your iOS devices, Android, and PC.

Frequently Asked Questions
Why does my OneDrive upload pause when I close the app on my iPhone?
iOS automatically restricts background activity to conserve battery life. If you leave the app during an upload, iOS may suspend it. To mitigate this, enable 'Background App Refresh' for OneDrive in your device settings.
Does the iOS Files app interfere with third-party cloud uploads?
Yes, occasionally the integration between the native Apple Files app and third-party services like OneDrive can glitch, causing only the first file of a selection to pass through. Uploading directly from inside the OneDrive app usually bypasses this issue.
What should I do if the upload fails even on Wi-Fi?
Try switching to cellular data to rule out network restrictions, clear the OneDrive app cache if possible, or uninstall and reinstall the app. Also, verify that your OneDrive account has not exceeded its storage limit.
