Phone shutdown in the middle of night. Alarm didn't go off

My S9+ shutdown in the middle of the night for some reason. It was charging, but would it overheat just from charging? Has this happened to anyone else? Snapdragon, T-Mobile version with March Security update (pathetic Samsung).

Weird! Hope that's just a one-time anomaly.

Regarding the security update, you must've received it before it was pulled. My GS9 has it, but my GS9+ doesn't.

I'm really frustrated that it's been on hold for so long. This will push me toward Pixel next time I upgrade.
