In my case my phone was never exposed to water or dust, even if I'm using a Brand provided charger , I'm still facing the issue. This is a temporary solution to a huge problem. I would suggest don't use your phone for at least 24 hours if still the notification pops up. Visit the Service Center. I'm also facing this problem. I'll wait for more than 24 hours. If it still doesn't fix it, I'll have to go to the Service Center also

Thank you for that description!
I'm only familiar with the hardware side of those issues.
Specific in my case there can be an issue with corrosion, a faulty charging port modul, a corrupted over volt protection ic, but it could also be a faulty resistor (plus minus 15% off it's range/value can also cause this) or a over heated trace in the circuit layers of the mainboard, cold solder joints etc., can also be a bad charger/cable.
There a three different warning symbols: One is the nfc part which gives a temp warning, one is the symbol with the water drop and the other is that triangle ( it can be liquid or corrosion but it doesn't have to, so basically it is just an over voltage protection because something is not right.

@@irepairitall kept the phone on direct sunlight for 30 minutes, then it was charging after charging several times, but there was no issue, but almost after a day, the notification popping up again wtf is that I have already charged my phone 5 times then its okk now it saying the same again I think it's a software issue and they should fix it for free.

@@irepairitall so much does it cost to fix the problem ?

[@irepairitall]

If it works when warm then it could be a bad connection/cold solder joint.

[@irepairitall]

Depends on where the issue lays, if it is a charging port issue it would be not that expensive.
