Understanding Quick Charge 4.0: Why Should You Choose It?

Fast charging technology was created to optimize battery charging times for smartphones. Qualcomm leads the way with its Quick Charge 4.0 and 5.0 products. Does your phone already have Quick Charge 4.0? Follow the article below to truly understand what Quick Charge 4.0 is and which devices support this fast charging technology.

What is Quick Charge 4.0 Fast Charging Technology?

Quick Charge 4.0 is the fourth-generation fast charging technology developed by Qualcomm, a company famous for its Snapdragon smartphone chips. Quick Charge 4.0 operates through a dual parallel charging process alongside normal charging.

As a result, phone manufacturers need to equip their devices with multiple chips and good thermal hardware to minimize the risk of heat buildup during charging. According to Qualcomm, Quick Charge 4.0 allows a device to charge from 0-50% battery in just 15 minutes while still using a USB Type-C port.

Pros and Cons of Quick Charge 4.0 Technology

Every product has its pros, cons, and factors that suit specific user groups. Quick Charge 4.0 is no exception. Let's explore the pros and cons of this product line.

1. Pros of Quick Charge 4.0

Qualcomm uses the INOV (Intelligent Negotiation for Optimum Voltage) electronic algorithm for Quick Charge 4.0. This algorithm helps control the charging current and voltage for the phone by allowing the chip to manage charging temperature in real-time. With just 5 minutes of charging, you can get an additional 5-6 hours of phone usage.

Compared to Quick Charge 3.0, Quick Charge 4.0 is 20% faster, with energy efficiency increased by over 30%. With these advantages, Quick Charge 4.0 can be considered an ideal super-fast charging technology.

2. Cons of Quick Charge 4.0

Unfortunately, Quick Charge 4.0 is only available to a specific group of users due to the phone chip and charging port requirements. Additionally, faster charging generates more heat in the battery, which leads to a small risk of safety concerns.

Is Quick Charge 4.0 Fast Charging Technology Safe?

Quick Charge 4.0 will automatically cut off power when the phone battery is fully charged. The protection and current regulation mechanisms of this technology ensure safety with multiple layers of protection throughout the charging process. Additionally, Quick Charge 4.0 cables are of high quality and can withstand heat very well.

Conditions for Using Quick Charge 4.0 Fast Charging

As mentioned above, Quick Charge 4.0 is designed for specific users. First, your phone must support USB Type-C to charge with Quick Charge 4.0. Second, Qualcomm has only integrated this fast-charging technology into smartphones using the Snapdragon 835 chip.

Comparison of Quick Charge 4.0/4.0+ and Quick Charge 5.0

Currently, Qualcomm's latest charging technology is Quick Charge 5.0. The Quick Charge 4.0+ technology is just a slight chip upgrade of Quick Charge 4.0. So, how do these two generations of fast charging differ, and has Quick Charge 4.0/4.0+ fallen behind compared to Quick Charge 5.0?

1. Charging Speed

Quick Charge 4.0 has a charging speed of up to 100W, similar to Quick Charge 4.0+, with the difference being that version 4.0+ is compatible with the Snapdragon 845 chip. The charging speed of Quick Charge 5.0 is slightly faster than its predecessors, but optimizing charging performance is a different story.

The charging efficiency of Quick Charge 5.0 reaches 70%, and the charging temperature is reduced by up to 10 degrees Celsius. Additionally, version 5.0 doubles the charging voltage by supporting two internal batteries within the phone. And, of course, Quick Charge 5.0 supports the premium Snapdragon 865 chip, which is compatible with more smartphones.

2. Charging Time

According to Qualcomm, Quick Charge 5.0 can charge a phone from 0-50% in just 5 minutes. This is a big surprise for many users, as Quick Charge 4.0/4.0+ takes about 15 minutes to charge from 0-50% battery. It should be noted that you can only charge up to 45W with single-battery phones, so the charging time may be longer.
