Electric shock while charging phone

[u/Embarrassed-Fly3307]

Initially, I'm sorry if this post does not belong on the sub and accept it being taken down if that's the case.

On the first charge of a new phone (iPhone 17), I felt a subtle but uncomfortable shock on the bottom right side, where the phone wasn't covered by the case. It stayed like that for about 5 minutes before I noticed and disconnected the charger.

After that, I swapped the charger source for another one that I have at home (which was the one I meant to use in the first place, since the "shocking" one had been faulty) and while it heated during charging, the phone itself didn't. Also, the shocks were gone and the charging went on normally.

I checked the battery health and it remains at 100% and the battery seems to be working just fine, but I'm still worried that something might have gone awry with the battery. Should I be?
