The basic building blocks for charging any electronic device comes in the form of amperage (current), voltage, and watts (power). In a fast charging scenario, charging of the smartphone happens in two phases. In the first phase, a higher voltage pushes the charging rate at a rapid pace – and different brands are trying to pack more charge in the first 20-30 minutes.
Once the battery has received most of its charge (about 80%), these fast chargers decrease voltage in a controlled manner to prevent overheating as well as overcharging of the device. This has also become a safe way to ensure that chargers as well as the battery inside the smartphone works smoothly and for a longer duration of time.
In order to get the best fast charging results, you need to have a compatible charger as well as cable that comply with the standards. And yes, if you are using a 25W charger with a smartphone that has a maximum charging speed of 20W, the device will charge only at 20W.
Some of the most popular types of fast charging standards are USB Power Delivery (or USB-PD) and Qualcomm Quick Charge. In addition to these, there are a number of brands such as Samsung, vivo, iQOO, which have introduced their own fast charging terminology such as TurboPower, FlashCharge, Adaptive Fast Charging, or SuperCharge.
