Apple introduced Liquid detection for their iOS devices in 2016 with iOS 10. Whenever liquid was detected in the lightning port of an iPhone, it came up with this message – “Disconnect Lightning Accessory :Liquid has been detected in the lightning connector. To protect your iPhone, disconnect this Lightning accessory and allow the connector to dry.” and had only one option – “Ignore”
With iOS 14, Apple has added a new option called “Emergency Override” which when enabled, will allow your iPhone to charge even if liquid is detected. The popup reads: “Charging Not Available: Liquid Detected in Lightning Connector. Disconnect to allow the connector to dry. Charging now may damage your iPhone.” and has two options under it – Dismiss and Emergency Override. The Emergency Override option allows users to charge their iPhone even if it detects liquid in the lightning port. This is handy when there is a type of emergency such as a medical one where you need to quickly charge your iPhone and make a call. This was first discovered by Mark Gurman from Bloomberg.
On iOS 13, it will just show the Dismiss option.
