iPhone kills any battery I connect to it

Hi,

My iPhone SE was out of charge (showing the connect charger symbol).

When I plugged it it turned on, then the screen went off. I thought it was the timeout.

After a while I came back and noticed the phone was not responding (screen does not turn on).

I thought it could be the battery, so I measured it. It was at 0V, which is weird because it was charging.

Anyway, I had a few old batteries that were still measuring over 3.8V.

When I put them, nothing happens and after I take them out, they also read 0V.

My guess is that there's a short circuit, which is also triggering battery overcurrent fuses and so any battery I put gets killed.

Does this rings a bell to anyone ?

Thank you!
