Qualcomm Quick Charge was one of the first technologies that bought fast charging to smartphones, and now many other manufacturers have followed suit with their own fast charging modules. Qualcomm had announced the fourth iterative upgrade for the charging tech six months back, and now the chipmaker has already introduced the Quick Charge 4+ standard.
The Quick Charge 4+ standard can be added to devices without an actual chipset upgrade, and the new standard will primarily boast of three new features along with the ones that already exist on Quick Charge 4. The dual charge is a feature that we have already seen in earlier Quick Charge generations. However, the Quick Charge 4+ is now more powerful. Dual Charge employs a second power management IC on the device, and it also divides the current, archives better thermal dissipation and thus eventually reduces charging time.
Intelligent Thermal Balancing finds the coolest path of current transfer and thus avoids the hot spots of power delivery. This helps in keeping the overall temperature at tab and also prevent overheating of the phone. Furthermore, the Quick Charge 4+ comes baked in with an Advanced Safety Features which will once again be monitoring the phone temperature along with the connector temperature. What this does is that apart from protecting the phone from overheating it also prevents short circuits.
As per Qualcomm, the devices with Quick Charge 4+ can be charged up to 15 percent as opposed to its the previous generation and the charging process will also be 30 percent more power efficient thus helping you save some juice on power banks. Also, the charging process will now be cooler. Since the Quick Charge 4+ is a hardware enhancement the chances are that you won’t get this on your current phone with a software upgrade. Currently, the QC 4+ is available only on the recently launched Nubia Z17 that comes powered by a Snapdragon 835.
