My phone shuts down when I’m about to upload a reel on instagram. How can I fix the problem?

Hello aphiwe116,

We'd be happy to get you headed in the right direction. If an app on your iPhone isn't working as expected, we recommend trying to resolve the issue by following the steps here: If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open - Apple Support

You may find these steps helpful:

1. Close and reopen the app

2. Restart your device

3. Check for updates

4. Delete the app, then redownload it

If that doesn't resolve the issue, you may need to check your battery. Your battery's chemical age plays a part in supporting peak performance and unexpected shutdowns. you can learn more here: iPhone Battery and Performance - Apple Support

Thanks.
