BRUSSELS: iPhone maker Apple on Jan 23 pushed back against EU lawmakers' call for a common charger, warning the move could hamper innovation, create a mountain of electronic waste and irk consumers.

Apple's comments came a week after lawmakers at the European Parliament called for a common charger for all mobile phones and amended a draft law to say the ability to work with common chargers would be an essential requirement for radio equipment in the bloc.

A move to a common charger would affect Apple more than any other company as its iPhones and most of its products are powered by its Lightning cable, whereas Android devices are powered by USB-C connectors.

"We believe regulation that forces conformity across the type of connector built into all smartphones stifles innovation rather than encouraging it, and would harm consumers in Europe and the economy as a whole," Apple said in a statement.

It said regulation was not needed as the industry is already moving to USB-C through a connector or cable assembly.

"We hope the (European) Commission will continue to seek a solution that does not restrict the industry's ability to innovate," Apple said.

A study by Copenhagen Economics commissioned by Apple showed that consumer harm from a regulatory-mandated move to a common charger would cost at least €1.5bil , outweighing the €13mil in associated environmental benefits.

The European Commission, which acts as the executive for the EU, has been pushing for a common charger for more than a decade.

In 2009 it got four companies including Apple, Samsung, Huawei and Nokia to sign a voluntary memorandum of understanding to harmonise chargers for new models of smartphones coming into the market in 2011.

The voluntary approach is not working and it is time to look into legislation, Commission officials said.

"A delegated act based on the Radio Equipment Directive (RED) is one of the options to be considered since it empowers the Commission to take certain type of regulatory measures in this field," the one of the officials said.

Another option was to pass legislation on the issue.

"...given the limitation in the scope of RED and of its empowerment, any action through ordinary legislative procedure and/or through other instruments, such as implementing measures under the Eco-design Directive should be further explored and thoroughly assessed," the official said.

The Commission will publish a study around the end of the month or early February on the impact of a common charger.
