For those who frequently use mobile phones for browsing the internet, reading, etc., continuous phone charging remains as common as having meals, even simultaneously while using the device. However, this practice can lead to faster battery degradation.
This is also why Qualcomm developed and introduced the Quick Charge fast charging technology. In the article below, Mytour will provide detailed insights into what Quick Charge 3.0 is all about.

1. What is Quick Charge?
As its name implies, Quick Charge is a technology that allows for faster device battery charging to reduce charging time compared to conventional methods.
Put simply, Quick Charge enables boosting the current into the battery to maximize charging efficiency. The latest Quick Charge-supported products can charge batteries with higher voltages, allowing for the transmission of more power through the charging cable.
However, both the phone and the charger must be compatible with the supported current and voltage. Assuming the phone supports 9V/2A charging, but the charger only supports 1A, the charging process will be slower. Similarly, plugging a 2A charger into a phone that only supports a maximum of 0.7A also cannot expedite the charging process.
Qualcomm's Quick Charge technology is designed to optimize energy transfer in the initial stage of charging. Even after unplugging, it ensures that the amount of charge delivered to the battery is sufficient for regular use.
2. What is Quick Charge 3.0?
Quick Charge (or QC) 3.0 is Qualcomm's third-generation fast charging technology. Essentially, Quick Charge 3.0 utilizes similar technology to Quick Charge 2.0 but with faster charging speeds.
In tests using a 2750mAh battery, devices supporting Quick Charge 3.0 charge from 0% to 80% in just 35 minutes, while regular charging only reaches 12% in 30 minutes.
Quick Charge 3.0 operates by utilizing an algorithm called Intelligent Negotiation for Optimum Voltage (INOV), developed by Qualcomm. INOV is a new algorithm that allows devices supporting it to determine the level of energy charged into the device at different times to ensure optimal power transmission efficiency. It supports power delivery at wider voltage levels, with each step being 200mV apart, ranging from 3.6V to 20V.
Furthermore, Quick Charge 3.0 is deployed similarly to its predecessors, and all QC 3.0 devices are fully backward compatible with Quick Charge 2.0 and 1.0 devices.
QC 3.0 supports USB Type-A, USB Type-C, and micro USB as well as other proprietary connections. Manufacturers can implement QC 3.0 across various charger types and devices.
3. How do Quick Charge 3.0 and 2.0 differ?
- Quick Charge 2.0 only delivers power at voltage levels of 5V, 9V, 10V, and 20V, meaning charging occurs in stages of power.
- Quick Charge 3.0 supports power delivery at wider voltage levels, with each step being 200mV apart, ranging from 3.6V to 20V.
- The advantage of QC 3.0 fast charging lies in providing power at wider voltage levels, hence faster charging.
- Standard fast charging operates at 5V, thus the charging process is slower.
