Can I get an alert when my iPhone 5S is unplugged?

My iPhone 5S gives a beep or buzz when I plug it in to a charger, but doesn’t provide any notification, apart from the lightning bolt in the top right hand corner disappearing, when it gets unplugged.

I’d like to get such a notification because my phone has a tendency to stop charging if the cable has the slightest touch to it - this happens with many different cables.

My phone is not jailbroken, so https://www.idownloadblog.com/2013/02/23/unpower-jailbreak-tweak/ doesn’t help. I’m on iOS 12.5.1, and according to Apple security updates, the iPhone 5S isn't supported for iOS 13 or 14.

You can reach that with the shortcut-app by creating an automation:

1. Open Shortcut-App and create a new Automation (click +)
2. Choose "Create Personal Automation"
3. Scroll the page down and select "Charger"
4. Choose "Is Disconnected" and click "Next"

5. Click button "+ Add Action"
6. Select "Show Notification", findable through the search field
7. Write the show notification as example "Is Disconnected from Power", then "Next"

8. Deselect "Ask Before Running" if this shortcut should be triggered automatically
9. Click "Done" and your shortcut is finished and executable
