EU countries and EU lawmakers are set to agree on a common charging port for mobile phones, tablets and headphones on June 7 when they meet to discuss a proposal.
The development will be a major setback for iPhone maker Apple. The US-based Apple is yet to comment on the issue.
The proposal for a single mobile charging port was first broached by the European Commission more than a decade ago after iPhone and Android users complained about having to use different chargers for their phones.
Customers can charge their Apple iPhones from a Lightning cable while Android-based devices are powered using USB-C connectors.
Outstanding issues include broadening the scope of the proposal to laptops, a key demand by EU lawmakers that is likely to impact Samsung and Huawei and other device makers.
EU lawmakers want to include wireless charging systems to be harmonised by 2025 while EU countries and the Commission wants a longer lead-in period for technical reasons.
Apple has previously said the inappropriate use of dated international standards stifles innovation and that forcing users to change to new chargers could create a mountain of electronic waste.
