Future iPhones to get USB-C port due to legal issues
Owing to the European Commission's intention to start an investigation for finding out if all the phone makers are using common mobile charger, Apple might have to employ USB-C port in its future smartphones. Currently, the iOS devices from Apple integrate Lightning port for charging the battery.
It was in 2009 that 14 smartphone manufacturers agreed and signed a memorandum of understanding (MoU) which asked them to use a common mobile charging port for all their models. Among these companies were Samsung, Huawei, Nokia and, Apple as well. After this agreement expired in 2012, a new letter of intent was signed by the same companies in 2013 and 2014.
Despite the regulation being valid, Apple still continues to use its exclusive lightning port. Moreover, it's upcoming iPhones, which are expected to come by September, are also predicted to come with the ongoing charging port. All the other manufacturers adhere to the regulations though.
However, the company is mulling over inducting USB-C in the smartphones which will come later and that is perhaps due to the legal issues in Europe, as suggested by rumours in the past.
An EU commission official told in a statement that the commission is disappointed on how the companies reacted to this regulation but it is still clearly unknown if any company will be investigated.
