The Metropolitan Police is calling on tech firms to make stolen phones harder to reuse and prevent criminals from profiting.
Met Police Commissioner Sir Mark Rowley has asked the home secretary for legislation to make phone companies publish data on stolen devices, and to enforce measures rendering handsets effectively unusable.
The police force revealed on Thursday that it had started sharing data with Apple to build a "global picture" of what happens to stolen handsets, including whether they are being reconnected to a network.
"If stolen phones cannot be reactivated, their value collapses, and so does the incentive to steal them," Sir Mark said.
In working with Apple to improve security, Sir Mark said only a minority of stolen phones were being reactivated compared to a few months ago, making it "harder for criminals to profit".
It follows an ultimatum the Met Police chief gave firms in March to enforce steps which would make stolen phones less desirable for resale and reuse.
London has some of the highest rates per thousand people of personal robbery and thefts in England and Wales.
The international trade in stolen phones is worth millions of dollars, with a device stolen in London worth more in countries like China because it has none of the government restrictions put in place by authorities there.
But according to the Met, the number of thefts where phones were stolen fell by 14,000 between June 2025 and May 2026 - down 18% on the previous year.
In Westminster, where between 69% and 72% of thefts from the person and personal robberies each week involve phones, there has been a reduction of 45.8% so far this year.
Kate Adams, senior vice president of government affairs at Apple, said: "Keeping our users, their devices, and their data safe is at the heart of what we do.
"That includes building industry-leading security features that significantly reduce the motivation for criminals to target people in the first place."
The Met said that Samsung and Google were also making security changes to tackle the issue.
