Qualcomm Snapdragon 835: 10-nm process technology and quick charge for 5 minutes – 3DNews

the event Technology Summit Snapdragon Qualcomm has officially announced a new flagship system for mobile devices — Snapdragon 835 that earlier in mass media it was called Snapdragon 830.

However, the architectural features of the new SoC, in particular the characteristics of its CPU and GPU, the company chose not to speak — the information they have saved at a later date. Now about the chip was that it is manufactured by Samsung Corporation for 10-nm process technology FinFET. This technology allows a 30 % increase in efficient use of chip area, at 27 % increase in CPU performance and 40 % lower power consumption.

the Key topic of the conference was the fast charging technology Quick Charge 4.0, because Snapdragon 835 — this is the first system-on-chip in which it will be applied. According to Qualcomm, the availability of quick charging is now one of the main criteria when choosing a new smartphone for 61 % of the users. While 26 % of owners dissatisfied with their current unit due to the fact that it takes too long to recharge, and 42 % complain of insufficient duration of Autonomous operation. These statistics chip maker explains why so much attention to developing technology Quick Charge.

5 hours 5 minutes

First of all, Quick Charge 4.0 become more productive: according to the developers, version 3.0 a new technology feature at 20% greater speed and 30 % increased the efficiency of recharge, and in comparison with the standard Quick Charge 1.0, the fourth generation is faster by 2.5 times.

To use Quick Charge 4.0 to obtain the energy sufficient for the average smartphone for five hours, just plug it to the power supply for five minutes. If you leave the unit to charge for 15 minutes, then charge its battery replenished by half. However, it is important to understand that these figures are somewhat standard, Qualcomm obtained in the tests conducted on the device with the 2750 mAh battery. Accordingly, the greater the battery capacity, the longer the process will last.

Safety first

a Separate part of the press conference in honor of the Quick Charge 4.0 Qualcomm devoted to security issues. On this topic she had a lot to tell, because the technology provides four layers of protection against overheating of the smartphone during charging, which is complemented by the three-stage overcurrent protection and the same levels of control voltage. In addition, specific protection circuits of the power supply, battery and cables. Speaking of the latter: smartphones with Quick Charge 4.0 will be able to detect the type of connected cable and its quality.

it is also Noted that Quick Charge 4.0 is compatible with USB Type-C and USB Power Delivery (USB-PD), in addition, it uses the third version of the algorithm of power control INOV (Intelligent Negotiation for Optimum Voltage) by which the system automatically selects the most appropriate for specific temperature conditions charging mode.

the Wait is long

during a press conference intentionally focused on Qualcomm Quick Charge 4.0, leaving behind the scenes technical details about the Snapdragon chip 835, in which this fast charging technology will be implemented for the first time. But waiting for official news about him will not last long: the chip maker promised to reveal cards already in the first days of January. As for devices based on Snapdragon 835, they will start to enter the market in the first half of 2017.
