Holidaymakers are being warned their mobile phones could be taken away from them at the airport if the devices aren't charged.
The little-known rule regarding electronics could catch travellers out while they are going through security checks. Any holidaymaker could be asked on the spot to prove their device's function, usually by turning the device on.
Experts from International Citizens Insurance say this can be "surprising" to passengers who have not read up on airline rules and regulations. They say: "If you cannot turn on your devices when requested by security personnel, they can take it from you, placing your holiday snaps in jeopardy."
