As of Thursday, saying the words "charge my phone 100 percent" into some iPhones caused the devices to automatically start calling emergency services.
While it was initially unclear if the odd feature was a software glitch or little-known safety feature, it seems that the function is no longer available.
Depending on which particular version of iOS your device currently has installed, Siri will now reply to the command with "I can't do that for you. My apologies," or "Surprisingly, that is not within my capabilities."
Apple did not immediately respond to a request for comment, nor did it respond Thursday when asked initially about the unusual feature.
