For fast charging, look for Qualcomm Quick Charge 4+ in your next mobile device

In study after study, we see that the top features consumers look for in their next device are extended battery life and faster charging. Qualcomm Technologies is dedicated to meeting both these needs with our Qualcomm Snapdragon Mobile Platforms and Qualcomm Quick Charge fast charging technology.

Snapdragon mobile platforms are designed with power efficiency to get you through the day on a single charge. With each generation, Snapdragon mobile platforms get better at meeting the demands of the power user. Take the Snapdragon 835. Compared to its predecessor, the Snapdragon 821, the Snapdragon 835 boasts a greater-than 25 percent power reduction. This allows you to do more power intensive activities on a single charge, such as VR gaming and 4K video streaming. While the goal is to get you through a day, or more, without the need to recharge, there will undoubtedly be the occasional need to reach for the power cord. That’s when Quick Charge can save the day.

When Quick Charge 4 was announced, it promised to bring even faster charging than its predecessor, allowing a device to go from empty to 50 percent in just 15 minutes. We added new technologies designed to further extend battery cycle life, enhance safety, and expand charging intelligence. These features come standard with a device that includes Quick Charge 4.

But we haven’t been resting on our accomplishments since then. In fact, since that time we developed new enhancements and created a special program for those device and accessory manufacturers who design their products with these new features included. We call this the “plus” program, as in Quick Charge 4+. Quick Charge 4+ includes all the benefits of Quick Charge 4, plus more.

On the mobile device side, Quick Charge 4+ includes all the benefits of Quick Charge 4, plus three enhancements. Manufacturers get the 4+ designation by including all three:
- Dual Charge: already an option in earlier versions, but now more powerful, Dual Charge includes a second power management IC in the device. Charging a device via Dual Charge divides the charge current, allowing for lower thermal dissipation and reduced charge time
- Intelligent Thermal Balancing: a further enhancement to Dual Charge, intelligent thermal balancing is engineered to move current via the coolest path autonomously, eliminating hot spots for optimized power delivery
- Advanced Safety Features: Quick Charge 4 already includes rigorous built-in safety protocols. Quick Charge 4+ goes one step further and is designed to monitor both the case and connector temperature levels simultaneously. This extra layer of protection helps ward against overheating and short-circuit or damage to the Type-C connector.

With Dual Charge, Intelligent Thermal Balancing, and Advanced Safety Features incorporated in a device design, that device has the potential to charge up to 15 percent faster, or 30 percent more efficiently when compared to Quick Charge 4.

Accessories such as wall adapters, car chargers, portable battery banks, and USB hubs can also qualify for Qualcomm Quick Charge 4+ designation. Such an accessory will include backward compatibility with Quick Charge 3.0 and Quick Charge 2.0. Having a 4+ certified accessory will help ensure that your existing Quick Charge 3.0 and 2.0 enabled devices will work with the latest commercially available adapters.

Manufacturers meeting the device or accessory requirements can use the 4+ logo on their products. Qualcomm Technologies will also include each of these in the Quick Charge certified device list so consumers will have an easy means to find qualifying products. Remember, not all power adapters are created equal. That’s why Quick Charge accessories go through a rigorous certification process to ensure they meet the stringent requirements set forth by UL.

Just this week, the first device to include Quick Charge 4+ support was announced, the nubia Z17. The nubia Z17 is one powerful smartphone featuring, in addition to Quick Charge 4+ and a 3200mAh battery, the Snapdragon 835 mobile platform with an impressive 8GB RAM and 128GB memory, 23+12 megapixel dual rear camera, and a 5.5” FHD frameless display.

With Quick Charge 4+, Qualcomm Technologies once again shows our leadership in charging technology. Since the first products came out over 4 years ago, Quick Charge technology has been included in over 130 mobile devices and 475 accessories, making it the most popular fast charging technology available by a wide margin. Quick Charge 4+ continues the fast charging innovation, providing design flexibility for manufacturers, and a diverse ecosystem of certified products for consumers. Be sure to look for Quick Charge 4+ in your next mobile device.
