Quick Charge 5 promises brutal charging speeds

| |

Qualcomm has announced the latest, fifth generation of Quick Charge technology. With noble simplicity, Quick Charge 5 is what the company calls the “world's fastest commercial charging solution,” and which, at least on paper, produces truly spectacular numbers. According to the chip maker, the technology allows a 4500 mAh battery to be fully charged in less than 15 minutes when discharged, and 5 minutes is enough to reach 50 percent charge.

Of course, not only the charger but the battery itself must support the new standard. To achieve the above results, a dual-cell battery is required, where the two cells can be charged simultaneously with a power of 50 watts each, so the charger thus delivers a total of 100 watts. With the dual-cell batteries, the manufacturer says charging can be up to 10 degrees Celsius cooler, 70 percent more efficient, and four times faster than the previous generation of Quick Charge, and it's worth mentioning that the standard supports an input voltage of up to 20 volts.

Of course, the double-cell arrangement required for similar impressive values ​​is far from widespread, as it achieves less maximum battery capacity than a conventional single-cell battery due to its more complex design. However, single-cell Quick Charge 5 batteries will also benefit from the new standard, albeit here with a maximum charging power of “only” around 45 watts.

Similar, extremely high-performance solutions also raise the question that they are larger. will not reduce battery life significantly faster in the long run than more comatose charging procedures. Speaking to AnandTech, Qualcomm said in this regard that battery technologies are now advanced enough to eliminate similar problems – although the company has not gone into the details of this.

The serious strength of the technology is that in any case, Quick Charge Devices 5 do not necessarily require a similar charger with plecsnit. Qualcomm already relies on the USB Power Delivery standard from its proprietary charge management protocol converted to Quick Charge 4 and continues to rely on the PD-PPS (Power Delivery Programmable Power Supply) protocol, making it compatible with other PD-PPS chargers that support the right voltages and currents . The Quick Charge 5 chargers themselves will be capable of charging notebooks or other larger devices.

The new standard will open up significant possibilities for charging smartphones and other devices faster than ever before, but it is questionable whether the potential sacrifices will be fully exploited. , such as slightly lower battery capacity or faster deterioration of battery life due to space constraints, will manufacturers undertake. This could be revealed later this year, with device manufacturers already having access to Qualcomm Quick Charge 5 chips, so the first models based on the technology could appear in the third quarter of this year.
