How fast charging of Samsung phones works

To charge a battery faster, it is necessary to increase the charging power (plus voltage and amperage), this simple principle was developed by manufacturers over the years until we had the 'fast charging' concept we know today.

Adaptive Fast Charginig fast charging is divided into two cycles, the first is when in a few minutes the power supply of the adapter causes the battery to quickly charge up to 50% of its capacity, therefore it is quite common for your phone to overheat.

Fast charging can be activated when your Samsung mobile has a very low charge, less than 20% or 15% when you connect it to the mains, the charger assigns a large amount of voltage to the device's battery without suffering any kind of damage, since its architecture allows it. 

When the charge percentage reaches 80% the voltage decreases noticeably, this is where you should be more careful, because if you increase the voltage it can damage the battery, so if you want to charge it to 100% you just have to wait a little longer to keep your device safe.

With that in mind, let's assume your phone is at 0%, when you use Adaptive Fast Charginig you will notice that your phone charges up to 50% faster than normal. But everything is different if it is 75%, since it will take to reach 100% almost like a common adapter, so we explained above.
