Battery capacity is one of the key characteristics of a smartphone. Smartphone batteries are getting larger and larger every day. The latest battery standard is 5000mAh, which promises a full day of battery life on a single charge. Charging speed is also of great importance in the modern world. Therefore, phone manufacturers have introduced a fast charging feature, which can significantly reduce the charging time of our phones.

how to charge your phone battery faster

So how does fast charging work?
First, we need to understand concepts such as amperage, voltage, and wattage. Amperage is the amount of electricity flowing from the battery to the device expressed in amps(A). Voltage is a measure of the pressure that causes the electric current to flow expressed in volts(V). Wattage is a measure of electric power expressed in watts(W). To calculate the total power, you need to multiply volts by amps. For example, 5V x 2A = 10W. We do not take into account the energy losses on a charger or a cable, as they are negligible.

With the knowledge of how to measure charging power, you can easily understand what fast charging protocols are. When a device and a charger are connected, their protocols coordinate with each other for the most suitable voltage and current. Simply put, your phone and charger agree on the maximum allowed power for fast charging of the battery, which will be safe for your device and won't overheat the battery. To find out which fast charging protocol your phone uses, you need to know your phone brand and CPU type.

Thus, knowing the version of the fast charging protocol that your smartphone supports, you can choose the right charger that will help to speed up the charging process as much as possible.
