iPhone 7+, iOS15.7. Never had this happen ever in the past. Just woke up earlier today to find out my iPhone battery continued to deplete overnight despite being charged. Looking at the settings, no apps were shown other than the overnight backup and app updates. Everything else was normal, same cable, same charger that I have been using from day 1 (and also for all my other phones). I attached the screenshots. Battery health is 94%. No over heating and my bedroom was air conditioned. Does anyone have any clue what happened?

Since then I rebooted the phone and it seems to be charging properly again. But What's going on here?

Are you charging it with a lightning to USB cable? Maybe clean out the charging port, as it is prone to collect a LOT of dust/lint over time. Maybe the charging cable isn't making a proper connection sometimes due to foreign matter.

I’ve seen that before. The charging indicator in the phone can register that the battery is charging if only a tiny bit of power is actually charging the battery. That’s usually because of a poor connection in the lightning port.
In your case, the normal standby battery drain was greater than the charging current - so the battery continued to discharge.
