Why is my phone battery depleting several % every minute now?

Samsung Galaxy A34 5G, Android 15, One UI 7. Literally never happened before until when I charged my phone in the morning. In the battery part for settings, it doesn't show any app that's unusually eating up resources. Recharging doesn't seem to really be that off, but discharging is extremely fast. Even my gaming laptop isn't even discharging the battery this much!
