Liquid detection in the lightning connector

Hi! Just want to ask if anyone experienced the sudden prompt of liquid detection in iphone 11? My phone was not exposed in any water source so i'm confused. It has been 4 days and now my phone already drained. I can't charge it due to the liquid detection still prompted. I already dried my phone to natural air flow even downloaded the water eject. Im somehow upset. Apple claim that iphone 11 is water and dust resistant however this thing happen even the phone was not expose in water. I barely use my phone since im working, i only use it after work. Im not the kind of person glued to my phone for the whole day. Hope someone knows how to fix this, or anyone from apple can explain why this happens? Thank you!
