Quick Charge 4 was introduced with the release of Qualcomm Snapdragon 835 two years ago, and the list of phones compatible with this rapid battery charging technology has been increasing with each passing month. Qualcomm continuously updates its dedicated webpage to showcase all the Quick Charge compatible devices, chargers, and controllers.

Most mid-range and high-end phones these days come with some form of rapid battery charging technology. The most widely used technologies are Qualcomm’s Quick Charge and USB IF’s USB Power Delivery. Phones from Honor, Huawei, Meizu, Motorola, OnePlus, OPPO, and Vivo use their proprietary fast charging technologies. The reason we think that Quick Charge 4+ is the best of all is that it is cross compliant with USB Power Delivery open standard.

Devices that use Snapdragon 630, 636, 660, 670, 710, 835, 845, and 855 should be compatible with Quick Charge 4 technology but not all brands implement it in their phones. Quick Charge 4/4+ is compatible with USB PD and is also backward compatible with older Quick Charge technologies. It can charge Quick Charge 4 compatible devices at up to 18W (9V×2A) and USB PD compatible devices at up to 27W.

Starting with Quick Charge 2.0, Quick Charge technology’s highest power output is capped at 18W, but there’s a difference. While Quick Charge 2.0 used fixed current and voltage, Quick Charge 3.0 and Quick Charge 4 uses dynamic current and voltage. Current is either 2.6A or 4.6A and voltage is set at anywhere from 3.6V to 20V with 200mV increments. When a USB PD device is charged using Quick Charge 4 charger or vice versa, a device is charged with 3V to 11V (with 20mV increments) and up to 3A (with 50mA increments). Dynamic current and voltage make sure that battery health isn’t degraded and the device doesn’t heat up significantly.

Motorola and Samsung use Quick Charge 2.0 technology license and market it as Turbo Power (capped at 15W) and Adaptive Fast Charge (18W), respectively. In comparison, OPPO phones use VOOC technology with 20W power input at 5V and 4A. OnePlus uses Fast Charge (20W=5V×4A) and Warp Charge (30W) in their newest phones. Huawei and Honor phones use either up to 22.5W (5V×2A, 4.5V×5A, and 5V×4.5A) or 40W SuperCharge rapid charging technology.
