Quick Charge Quick Charge

Fast charging Active use of a mobile device inevitably leads to the discharge of the built-in battery. If the owner uses special programs, launches games and other applications, then the battery will drain faster. To charge a smartphone or tablet, it will take about 2-3 hours of time, provided that a regular memory card is used (with a current of 2.0A).

However, Qualcomm thought about gadget buyers and developed a quick charge system. This phrase means a set of components. This includes: power supply, cord, processor, etc. All elements must be compatible with this technology.

Fast charging is only suitable for devices with Snapdragon processor installed!

The principle of operation lies in the interaction of the processor and the power supply. When the charging cable is connected to the device, the general characteristics are analyzed and the preferred charging power is selected. As the battery charge increases, the amperage decreases.

At first, the current level can be in the range of 3-5 mAp. This is a shock dose to replenish the critical battery capacity.

  • Quick Charge 2.0 offers a 0-50% charge in 30 minutes,
  • Quick Charge 3.0 delivers up to 80% charge in 35 minutes,
  • Quick Charge 4.0 promises to give 5 hours of battery life in 5 minutes of charge, while controlling the temperature of the device, and the case practically does not heat up.

Among users who have managed to use fast charging technology, only the approval of such technology is found. When there is no time for full charging, but at the same time the active use of the gadget is ahead, fast charging comes in handy.

Doubt causes the initial stage of the process, since at this time more energy is supplied to the battery than it needs for a normal charge. The harm of this function has not yet been proven by anyone. If we take into account that, on average, smartphones and tablets are used for 1-3 years, then there should be no noticeable negative impact.

Fast charging

Please note that not all Snapdragon devices support QC fast charging technology. Since the license to use is paid, some manufacturers install their own charging protocol on devices.

So, the company Lenovo has TurboPower, implemented on a smartphone under the brand Motorola; MediaTek – Pump Express, designed to work with its own processors, and other options.

The compatibility of a particular device with one or another type of fast charging must be checked on the manufacturer's website or support service.
