Quick Charge 4 : Qualcomm charging smartphones in flash mode – ITespresso.fr

While smartphones are used more and more in the course of the day, it becomes imperative to always recharge more quickly.

This is where the new version of the technology of quick charge, signed Qualcomm. Called Quick Charge of 4, it will be available with the next generation of SoC (system on Chip) for mobile, which will begin with the Snapdragon 835, the marketing of which is scheduled for the second half of 2017.

” As mobile devices become more capable and feature rich, people tend to use them more. That is why the demand and the awareness of consumers with respect to the solutions of quick-charge are now at a record level, ” said Alex Katouzian, senior Vice-President, in charge of product management within Qualcomm Technologies.

” Quick Charge 4 address this need by providing up to 50 percent of battery charge in about 15 minutes or less, so that you don’t have to spend all day chained to your charging cable. “

The usage example cited above relates to a mobile terminal equipped with a battery of 2750 mAh. More meaningful still, 5 minutes of recharge is enough to get 5 hours of battery life on a smartphone.

Qualcomm has recourse to the process known as ” Dual Support “. This translates to a recharge 20% faster and 30% more efficient (in terms of heat dissipation) to be compared with the Quick Charge 3 (the previous generation).

To do this, the california-based company operates its algorithm INOV (Intelligent Negotiation for Optimum Voltage) 3rd generation. It now includes a dimension that is real-time with respect to the adjustment of the delivered power.

The technology is backed by security features, both side ac adapter and mobile device. To this end, the temperature is measured in real-time. In addition, a new layer of security prevents overcharging of the battery.

Quick Charge 4 requires integrated circuits with so called “power management” (power management) SMB1380 and SMB1381.

Between need to increase the battery capacity, decreasing the charging time and ensure safe, Quick Charge 4 has to deal with powers the high, which are administered at appropriate times. The exercise is not simple, as evidenced by the setbacks of Samsung with the Galaxy Note 7.
