Even Honor, like all mobile device manufacturers, has adapted to the new Fast Charge standards, in order to bring users safely to the end of the day, perhaps with only 5 minutes of extra charging.
The 50 and 50 SE have a 66W charging system; the 50 PRO even of 100W.
WHAT IS FAST CHARGING?
The expression "fast charging" is on the lips of all device manufacturers, from smartphones to laptops, from cables to chargers. But what does it really mean? The term "Fast Charging" is frequently used for the marketing of chargers and devices capable of charging faster than the current charging standard (5W). While there are several technologies that allow for these high charging speeds, there is still no standard terminology on this subject. In addition to this lack of compliance, it is good to know that although many manufacturers boast fast charging speeds for their products, the charging provided may simply be the standard 5W.
HOW FAST CHARGING WORKS
AMPERAGE X VOLTAGE = WATT
The basic elements of charging are amperage, voltage and watts. Amperage (or current) is the amount of electricity that flows from the battery to the phone or other connected device. Voltage is the speed or strength of the current. Watts are obtained by multiplying amperage and voltage. A frequent comparison is that of the watering hose: the amperage (or current) is the diameter of the hose, the voltage is the water pressure and the watts are the amount of water that comes out of the hose.
SO HOW DOES FAST CHARGING INCREASE SPEED?
Charging takes place in two stages. In the first stage, a higher voltage increases the charging speed. Fast recharging chargers use this step to increase power flow. As soon as the battery has received a large part of the charge, the charger reduces the voltage to prevent overheating or overcharging, thus ensuring the safety of your smartphone and charger.
With the quick charge, charging efficiency is maximized, raising the level of power (or wattage) that can be absorbed by the battery. By decreasing the charging times. In fast charge systems, the voltage of the current is increased while the amperage remains almost unchanged. Obviously the devices have chips to handle these much more powerful current flows than in the past.
AND IN THE FUTURE?
While waiting for the lithium-ion battery sector to be retired by new technologies, perhaps graphene, for smartphone owners the most convenient solution are fast charging systems that allow you to have 50% autonomy or less. with a few minutes of charging.
AND THE OTHERS?
Here are two graphs concerning the major manufacturers in which charging time and temperatures are highlighted. Very interesting article for those wishing to learn more:https://www.xda-developers.com/charging-comparison-oneplus-huawei/
Is fast charging dangerous?
Contrary to what one might think, the fast charging system is not dangerous. In reality the opposite is true. Work on managing incoming power to phones has led to higher security standards that manufacturers must follow. So much so that at the moment almost all brands that make smartphones have implemented the quick charge on their models.
Does your device already adopt fast charging?
