Reducing charge times has been a key point in the smartphone industry for many years. Imagine a charger that does not only detect charging current but can also deliver the maximum power the device is capable of taking from the charger. This is how Qualcomm’s quick charge technology comes into the picture.
The introduction of quick charge technology on high-end devices means you can now charge your battery around 70 percent faster. So, what’s a quick charge? How does it work? Does your phone have a quick charge? Read on, and we’ll explain all.
Quick Charge is a technology introduced by Qualcomm, which is implemented on Snapdragon chipset devices such as tablets and smartphones that focuses on pushing in more power to charge the device battery faster than standard USB rates allow. Qualcomm finds a way to increase power transfer across the wire by increasing voltage, which sends more power to your device. This more power gives you more charge in less time.
Technical certification and compatibility are two essential points to achieve fast charging. To take advantage of Qualcomm Quick Charge, both the corresponding charger and the mobile device must have an activated chip installed in their hardware. Without that activated chipset in both the charger and mobile device, Quick Charge will not happen.
Quick charging intends to charge your device faster than ever before. It can be categorized into five types, namely- Quick Charge 1.0, Quick Charge 2.0, Quick Charge 3.0, Quick charge 4.0 and the latest version Quick charge 4+ with each having a backward compatible with the previous one, so older adapters and cables will still work.
Quick charge 1.0 could support 5V and 2A. Many devices on the market support 5V 1A, and standard USB ports output a minimum of 5V, 0.5A. Quick Charge 2.0 bumps up the voltage at intervals of 5V, 9V, and 12v while Quick Charge 3.0 can support voltage across a different range from 3.2V to 20V, though peak power is 18W.
Quick Charge 4 allows your device to be charged from empty to 50 percent in just 15 minutes while also maintaining the ease of use of USB Type-C connectors. Quick Charge 4+ comes with all the benefits of Quick Charge 4 and is backward compatible with Quick Charge 3.0 and 2.0. Quick Charge 4+ devices are compliant with USB Power Delivery and use USB-C ports.
When you use quick charge, the voltage will increase but current will not. The only way your device can receive additional power is if the charger and the phone or tablet is rated to handle the increased voltage.
However, your device will charge at the standard 5 volts if any one of these components isn’t compatible. This will helps safeguard any device that’s not rated to handle the increased voltage. A device with Quick Charge shouldn’t attain a higher temperature than it would during a standard 5-volt charge.
The quick charge standard you’re able to use depends on the device you have. Check what your phone supports, then look at your wall adapter to see if it supports the same standard.
Many of the latest tablets and smartphones support Quick charge 2.0, 3.0 and 4.0. OEMs supporting Quick Charge include iPhone, Samsung, HTC, LG, Sony, Xiaomi, and ZTE.
However, there are only two devices that Qualcomm confirmed it’s fully compatible with its 4+ technology. The Razer smartphones and Nubia Z17 are the first devices to integrate Quick Charge 4+.
