Tencent Digital (Wen Xin) According to the “Telegraph†website, a study showed that because the antenna signal will be weakened, the left hand holding the iPhone during the call will affect the quality of the call.
A study commissioned by the Danish, Swedish, Norwegian, and Finnish telecommunications regulatory authorities and the Nordic Council of Ministers showed that Apple’s equipment ranks among the worst voice quality smartphones, with the iPhone 6s and 6s Plus being the worst performers.
Gert Frølund Pederson, a professor at Aalborg University in Denmark, tested 26 phones on the market and ranked them according to signal quality.
"The Telegraph" said that in all mobile phones involved in the test, iPhone 6s and iPhone 6s Plus call quality is the worst, iPhone 6 and iPhone SE ranking is also quite low. However, when it was held in the right hand, all Apple phones performed slightly better.
Pedersen told Ritzau, the Danish news agency, "Apple had problems in the past and it still has problems. And it seems that the more recent the issue of Apple's mobile phone, the more serious, which is somewhat unbelievable."
Apple today announced two mobile phones, the iPhone 7 and the iPhone 7 Plus. The location of the antenna has changed. Whether this can improve the quality of the user's left hand holding phone calls remains to be seen.
This is not the first time the iPhone has encountered a call. The iPhone 4 released in 2010 incorporates an antenna and a border. When holding a part of the phone, the signal will be attenuated to a level that cannot be talked.
Later, Apple gave a free protective shell to the affected iPhone 4 users, improved the signal conditions, and modified the signal algorithm.
"The Telegraph" said that in the test, the three handsets with the best call quality when holding with the right hand are the HTC Desire 626, the Samsung Galaxy S5 Mini and the Samsung Galaxy J1. The three phones with the best call quality in the left hand are the DORO PhoneEasy 530X, the Microsoft Lumia 640 and the Lumia 650.
Danish Energy Minister Lars Christian Lilleholt told Ritzau that he hopes Apple and other handset makers will take this research seriously.
