An old wive’s tale about an iPhone “hack” has resurfaced online, and people are reminding everyone what happens when you tell Siri “17” and why you should never do it in the first place.
In 2019, there were rumors where if you told Siri “17,” it would increase your battery life. Naturally, the idea of something so simple extending battery life without needing a charger intrigued a ton of people — so many that, at the time, “what happens when you tell Siri 17” was the third Google suggestion to pop up when you searched “what happens.”
In reality, the hack doesn’t work and if you do tell Siri “17,” you will unwittingly be calling for emergency services.
According to the Siri user guide, iPhones automatically call the local emergency number no matter what emergency number you say.
For example, if you told Siri “911” in France, you would contact the closest French police station even though 112 is the French emergency number.
This is a great, potentially life-saving feature should someone be in a foreign country and need immediate help without knowing the country’s emergency number. However, if there isn’t an emergency and you’re just telling Siri “17” — which is the emergency number for a small region in France — you’re wasting a lot of people’s time.
