Why is my iPhone 16e dead after overnight charging?

All you can do is to unplug the charge cable, put it back in and observe if you get the charging symbol - it may take a moment or two if the battery is completely drained.

Sometimes even usb-c cables fail to connect.

In a 16e I would be surprised if it wasn't 100% battery health.

Wired or wireless? If wireless, it may not have been positioned correctly on the charger. The 16e doesn't have mag-safe. If it gets knocked off center, it may not charge.

Hello, I suppose there may be 2 issues: your phone didn’t charge properly or your battery health isn’t good.

Firstly, you may plug or unplug your cable and adapters to see if your phone’s charging well or not. There should be indicators that your phone is charging well and you may check if the battery has risen or not.

Secondly, you may check your phone’s battery health for further information on your battery state.

If further issues persist, please reach out again and inform the Apple care service, we will always be ready to help. Thanks!

Charging stand as in a third party accessory? They are typically unreliable, some even drain the phone after charging. Use the cable that came with the phone or a genuine Apple accessory designed for the 16e

BTW I have seen a lot of aftermarket cases for 16e and SE with built-in magsafe rings. Takes out the guesswork.
