What Improvements Does the Qualcomm Quick Charge 4+ Brings Compared to Quick Charge 4.0

By July 13th, 2017 AT 10:34 AM

In the recent years, smartphone users have been optimistic with the all the tech that charged a device within minutes while making it last for hours, all thanks to Qualcomm’s fast charging technology. Fast Charging helps charge any device twice as fast as standard chargers, given the hardware of that device supports it.


While OnePlus Dash Charge technology is leading the charging technology, but Qualcomm’s Quick Charge technology is not far behind when compared to it.

Now, Qualcomm announced a brand new upgrade to their Quick Charge series, named Quick Charge 4+ at the start of last month. This comes just six months after the company announced its last Quick Charge 4 that promised up to 50% battery charge in just a matter of 15 minutes. The Quick Charge 4 has been in the smartphone market for a while now. However, the new Quick Charge 4+ takes it up a notch by adding three new enhancements.

30% More Battery Efficiency

With Qualcomm Quick Charge 4+, the company claims an additional 30% increase in battery efficiency, a less heated battery by 3 degrees, and up to 15% faster charging. With the ‘dual charge feature’, Qualcomm includes a second integrated power management circuit that separates the charge current and helps charge the battery much faster and more efficiently at that.

Intelligent Thermal Balancing

Yet another feature that comes with the Quick Charge 4+ is its ‘intelligent thermal balancing’. This prevents the battery from heating up frequently by redirecting the path of current to the battery via the coolest routes available. Additional ‘advanced safety features’ not only monitors the temperature of the battery but also that of the phone case and the Type-C USB connector of the device, improving the already existing built-in safety measures of the Quick Charge 4.

Supports Dual Charge

Qualcomm announced that the Quick Charge 4+ works for accessories as well including wall adapters, USB hubs, and portable battery banks. These accessories will also support backwards compatibility with the older versions of Quick Charge 2.0 and Quick Charge 3.0.

The new Qualcomm Quick Charge 4+ was first demonstrated in a smartphone announced early in June – the Nubia Z17. Along with this fast charging technology, the Nubia Z17 comes with 8GB of RAM and Qualcomm’s Snapdragon 835 chipset. The handset flaunts a dual-camera setup with 2X optical zoom on the rear and packs a 3,200mAh battery inside.

Hey Siddhant Bora, how did you enable carrier aggregation using your modem file? I want to test it out in my redmi note 4. I believe the hardware supports it, but it’s not enabled on the software part.
I hope you see this message.
