Invented not two decades ago, but more than two centuries ago, the analog audio connector (audio jack in English) of analog signals is used to connect microphones, headphones and other analog signal systems to electronic devices, especially audio. Created no less than in 1878, the 6.35mm original jack It was used by telephone operators for line exchanges. It was later used to connect musical instruments and microphones with amplifiers, emerging in 1964 the smallest 3.5 mm jack Used for headphone output on portable devices.

An old technology although certainly effective, mobile phones began to incorporate this output when their functions increased and allowed them to connect hands-free and play music after 2000. They have been using it for more than 15 years, and the trend in some companies –Apple ‘got rid of him in 2016– is to get rid of it and change it for more modern technology, such as Bluetooth helmets or USB Type C physical output. And that is what Samsung has done, which in its newly introduced Samsung Galaxy Note 10 has decided dispense with the characteristic port that has resisted until Galaxy S10 presented at the beginning of the year.
But what was the reason for this decision? According to a company representative has commented to the web The Verge, the elimination of the 3.5 mm jack space has been to make room for a slightly larger battery, about 100mAh more – equivalent to a 2-3% more load. And also as part of an improvement of the terminal haptic process, as this eliminates a hollow cavity in the smartphone – although there is still the space in which the S Pen is stored.
This only confirms the tendency to abandon the classic headphone port itself, although it seemed that it was returning to stay as we saw with the Lenovo Moto Z4 or the Google Pixel 3A. But the reality is that brands like their own Samsung, Apple, Huawei, Xiaomi, Oppo, Vivo or OnePlus They are discarding the output of their most recent mobiles. The end of an era (analog), no doubt.
