Unveiling the Wonders of Fast Charging Technology on Smartphones
1. What is fast charging technology on phones?
To meet the growing demand for mobile phone battery usage, various accessories have emerged such as batteries and power banks. With fast charging technology, you no longer need to carry an extra battery or power bank with you every day. Fast charging is a feature integrated into many smartphones today, especially since 2018.
Simply put, fast charging is a feature that helps you charge your phone battery faster, reducing the time it takes to fully charge. The basic USB charging cable specifications are 0.5A, 5V, and 2.5W. Fast charging technology has higher specifications, such as Huawei's SuperCharge 2.0 at 10V, 4A & 40W (16 times faster) and Samsung's Adaptive Fast Charging at 15W (6 times faster).

2. Working principle of fast charging technology
Principles of Fast Charging Technology
Fast charging technology utilizes high output voltage to charge the battery faster. Once the battery is nearly full, the current is reduced back to normal levels through the integrated chip in the charging adapter.
Irregular changes in current can adversely affect the device components. Therefore, it is crucial not to use fast charging cables that are incompatible or unsupported by your phone. For supported phone models, manufacturers have calculated to ensure stable operation under all conditions.
