Fast Charge

Fast Charge is a special technology designed to charge your smartphone battery in a relatively short period effectively. The key parameter in the characteristics of the charging unit is its power. Today you can find units with a capacity of 20, 65, and even 120 watts. In numbers, it all seems quite interesting, but what in reality?

Let’s start with the fact that for the fast charging to work properly, the phone must necessarily support this option. Also important is the power of the power supply itself. This parameter will directly depend on the time of the battery gaining the cherished 100%. You have probably noticed that the first 70-80% of the battery, the phone gets for 30-60 minutes. This is explained by the presence of two phases in the charging cycle.

During the first phase, the power of the power adapter is used to its full capacity. This is done primarily to reduce the wear and tear of the battery. A minimum current and voltage are used in the second phase, usually between 80 and 100 percent of the charge. If the battery were to receive a huge amount of power during the entire charge, all this would cause the battery to break down.

To illustrate, consider the simple example of a sponge. When completely dry, it absorbs liquid perfectly in a matter of seconds. This is our first phase of charging the battery (between 0 and 80 percent). Subsequently, when the sponge becomes wet enough, it will absorb the rest of the water very poorly and slowly. This is similar to the second battery charging cycle (between 80 and 100 percent).
