999 Phone Charging Myth

The 999 phone charging myth is an urban legend which claims that if a mobile phone has low battery then dialling 999 and immediately disconnecting charges the phone battery. This was confirmed a myth by British police.

Origin
The myth is believed to have originated on BlackBerry's forums. The basis of the myth was a feature on BlackBerry phones. If the battery level was too low, the phone automatically locked down phone features and shut down the phone radio for all calls except emergency services.

One urban legend claims that if Siri on an iPhone is told, "Charge my phone to 100%", the phone would call emergency services as a secret safety code. This myth originated from an actual bug in Apple programming that was later fixed.
