Qualcomm, the leading chipmaker, has been working on providing rapid charge to our phones and is one of the most trusted manufacturers that is helping in mitigating the issue of slow battery charging.

It is now introducing Quick Charge 4+ charging system, almost six months after its predecessor, Quick Charge 4. The technology includes all the perks that the latter brought about but comes with three more enhancements –

  • Dual charge: This feature includes a second power management IC in the device. Already present in the earlier versions, the revamped option is more powerful.
  • Intelligent Thermal Balancing: It intelligently moves the current through the coolest one of the dual pathways, eliminating hot spots for optimized power delivery.
  • Advanced Safety Features: Even though Quick Charge 4 was built with adequate safety measures, the newer version outdoes it. It keeps in check both – the case and connector temperature levels simultaneously. This shields the ward against overheating and short-circuit or damage to the Type-C connector.

The three boosted developments combine to make Quick Charge 4+ up to 15 percent faster and 30 percent more efficient than Quick Charge 4, which itself was designed to let phones charge from nil to 50 percent in a matter of just 15 minutes. Several accessories including car chargers, portable power banks, USB hubs can qualify for this new Qualcomm certification. They will also include backward compatibility with Quick Charge 3.0 and Quick Charge 2.0.

Also, having Quick Charge 4+ certification will ensure that the existing Quick Charge 3.0 and 2.0 enabled devices will work with the latest commercially available adapters.

The first device that is compatible with Quick Charge 4+ is newly launched Nubia Z17. In addition to supporting this charging technology and a 3200mAh battery, the Snapdragon 835 mobile platform comes with 8GB RAM and 128GB memory. It also boasts of a dual rear camera of 23 and 12 megapixels.

Quick Charge technology has been included in over 130 mobile devices and 475 accessories since the first version came out four years ago.
