No, both the smartphone and the charger plus cable need to support the Quick Charge protocol. Without compatible hardware, the device only charges at standard USB speed.

Quick Charge: Definition & explanation
In a nutshell
Quick Charge is Qualcomm's fast-charging technology for smartphones and other devices. It dynamically raises voltage and current to significantly cut charging time. It requires a compatible charger and cable to work.
How does Quick Charge work?
Quick Charge (QC) is a charging protocol developed by Qualcomm, controlled via the Snapdragon chipset and a compatible charger controller. Unlike standard USB charging with a fixed voltage (usually 5V), Quick Charge negotiates voltage and current between charger and phone. Depending on the version (QC 2.0, 3.0, 4.0, 5.0), voltage ranges from 5V to 20V in fine steps (INOV in QC 3.0) to achieve optimal charging power with minimal heat generation. Newer versions like QC 4.0+ also support USB Power Delivery (USB-PD) for better compatibility with other devices and standards. For Quick Charge to work, the smartphone, charger, and USB cable must all support the protocol — if one component is missing, the device charges only at standard speed. The technology is mainly used in Android devices with Qualcomm processors, while Apple and many other manufacturers rely on USB-PD. Modern chipsets also regulate charging power based on temperature to minimize battery wear and thermal stress.
Advantages of Quick Charge
- Significantly shorter charging times
- Widely adopted across Android devices
- Smart voltage/current adjustment
- Backward compatible with older QC versions
Disadvantages of Quick Charge
- Requires matching charger and cable
- Not compatible with Apple devices
- Can generate more heat
- May accelerate battery aging with frequent use
Frequently asked questions
Quick Charge is Qualcomm's proprietary protocol, while USB Power Delivery (USB-PD) is an open industry standard. Newer Quick Charge versions also support USB-PD for better cross-device compatibility.
Modern implementations regulate charging power based on temperature, keeping stress on the battery low. However, very frequent fast charging can slightly accelerate battery aging compared to slow charging.
