How does fast charging work?
Modern smartphones use lithium-ion batteries. It is already impossible to increase the operating time of such batteries, but you can speed up the charging process. Fast charging technologies optimize it in two ways: Quora
- increasing electrical voltage;
- increasing current strength.
Quick Charge Standard
Many companies are developing their own fast-charging protocols, but Qualcomm’s technology called Quick Charge has gained widespread acceptance. Quick Charge Quick Charge can be used with HTC, LG, Nokia, Xiaomi and other Android smartphones. Simply put, it works on all phones that are equipped with Qualcomm processors.
Technologies like OnePlus Dash Charge, Huawei Super Charge, Samsung Adaptive Fast Charge and Motorola Turbo Charge are based on Qualcomm’s Quick Charge or compatible with it.
What happens when you charge your phone?
During normal phone charging, a voltage of 5 volts and a current of 1 ampere are supplied via regular USB. As a result, the smartphone is 5 watts of electricity.
Quick-Charge in version 3.0 charges the battery using voltages up to 20 volts and a current of 4.6 amperes. To prevent the smartphone’s battery from being damaged, it is charged with a capacity of no more than 20 watts. As a result, the battery is replenished by 50% in just half an hour – or even faster. But the remaining 50% charge longer.
Is fast-charging harmful for a smartphone?
No, it’s not harmful. In order not to damage the device, when using Quick Charge technology, the supply of electric current is regulated. However, when charging quickly, the battery becomes very hot, which reduces its service life. We do not recommend using the smartphone while charging, so as not to make it heat up even more. If possible, charge the battery in a cool place or in the shade, and to speed up the process, turn on the “Airplane” mode.
If your phone is not compatible with Quick Charge, but you still charge it with such a USB charger, your smartphone will not be damaged. He just gets as much energy as he needs.
