Know that refreshed feeling you get after a quick power nap? With Qualcomm Quick Charge 4+ technology, your smartphone can experience a similar “restorative” effect.

Qualcomm Technologies continues to be a leader in power management, and we’re excited to extend this with Quick Charge 4+, designed to deliver the ultimate fast-charging performance for mobile devices. Quick Charge 4+ is our fourth-generation fast charging solution that features all the benefits of Quick Charge 4 and more, such as Dual Charge and Battery Saver, created to add speed and safety, while reducing charging thermals.

What Quick Charge 4+ really offers is the speed of convenience. Even though Qualcomm Snapdragon-powered devices are very energy efficient and just sip your power, once in a while, your battery does get depleted. With Quick Charge 4+ technology, an enabled device can get up to a 50 percent charge in only 15 minutes1.

One charging solution for all

Is your Snapdragon-powered device one of many that features Quick Charge? If not, never fear – we have you covered. Quick Charge 4+ chargers enable devices to be charged without Quick Charge technology or Snapdragon architecture inside them. This is possible because Quick Charge 4+ supports USB Power Delivery (USB PD) as its primary signaling method, which is a communication protocol used by many of today’s smartphones. This enables Quick Charge 4+ to offer a “one charging solution for all” experience. So, if your device doesn’t have Quick Charge technology inside it, but it does employ USB PD, you can still use a Quick Charge-enabled charger and improve your charging experience.

There are a wide variety of charger accessories available from smartphone and third-party manufacturers. This opens the door for you to select Quick Charge 4+ as your charger technology of choice. How do we stack up? Ventev, a global manufacturer of charging accessories, compared the charging performance of their Quick Charge 4+ wall charger, available soon, against chargers included in the box or sold by device manufacturers that use other fast charging methods. Their test results revealed that their Quick Charge 4+ adapter charged the devices at the same rate, or faster.

Dual Charge keeps your device cool

Dual Charge technology, exclusive to Quick Charge, is enabled by including a second power management IC in the device (i.e. a smartphone). Charging a device via Dual Charge divides the power, allowing for lower power and thermal dissipation, and reduced charge time, without performance tradeoffs.

With traditional charging, as your phone charges, the power flows through a single power path, which can cause your phone to receive less power to avoid excess heat, thereby lengthening your charging time. To address this thermal management issue, Dual Charge prescribes two paths, autonomously splitting between two lines, spreading the charge to create cool paths for power delivery. Through intelligent thermal balancing, Quick Charge 4+ can further reduce the overall heat dynamically, as it ensures power and thermal balance between the power paths.
