With new data revealing at least five phones have been lost on the South Western Railway (SWR) network every day since the iPhone 15 launched last year, customers are being warned to keep track of their phones.
SWR has logged more than 1,750 lost phones since September 22, 2023.
Alongside the phones, more than 600 earphones have also been reported missing during the same period.
However, the actual number of lost devices is likely much higher, as not all lost property is handed in and not all customers report their devices as missing.
The figures come after Apple released the iPhone 16 on Friday, September 20, priced from £799.
SWR estimates the value of phones lost on its network in the past year may exceed £1 million.
Since the first iPhone launched in 2007, it is estimated more than 30,000 phones have been lost on the SWR network.
The devices are among the most frequently lost items on the SWR network, along with clothing, bags, wallets, and glasses.
Since the release of the iPhone 15 on September 22, 2023, SWR has logged almost 22,000 different lost property items.
Jerome Pacatte, head of stations and revenue protection for South Western Railway, said: "Losing a phone or any other personal belonging during a journey can cause stress and anxiety, but our lost property team works incredibly hard to reunite customers with the hundreds of items lost on our network every week.
"While it might feel impossible to get your lost property back, we successfully return many items to their owners, so we strongly encourage customers who have lost something to get in touch with us.
"To end every journey on a positive note, we advise customers to take some time before reaching their destination to double-check they have everything."
Out of the more than 1,750 phones handed into lost property since last year, just fewer than 1,000 have been successfully returned to their owners, leaving a sizeable minority unclaimed.
Customers who lose their phones or any other personal belongings during their journeys can register them via the SWR website.
If the item is handed in, customers will be able to collect it in person for free or pay to have it posted to them.
If customers think they have lost something, noting the time of the train and the carriage number will help the lost property team locate their item.
