Fast charging vs flash charging! What is the difference between the two charging methods? Finally figured it out

As mobile phones become more and more powerful

Everyone has become a mobile phone addict

Not only are mobile phones becoming more and more intelligent

Charging is also more convenient and faster

Nowadays, fast charging and flash charging are the charging methods

It has become the standard configuration of major mobile phone brands

There is only one letter difference between the two

But the essence is very different

Fast charging increases voltage and reduces current

The principle of fast charging is to increase the charging voltage. The phone will show that it is fast charging, and the main function is the charging head.

Advantages: Because the current is low, the compatibility is strong, and there are no high requirements for data lines, so the cost is low.

Disadvantages: Increasing the voltage will generate higher heat, causing the phone to heat up and affecting battery life.

Note: Fast charging does not have high requirements for mobile phone chargers and data cables. You can use a charger that supports flash charging technology without causing substantial damage to the mobile phone battery.

Flash charging reduces voltage and increases current

The principle of flash charging mentioned by many brands is to increase the charging current. Under the condition of constant voltage, the higher the current, the shorter the time it takes to fully charge the battery.

Advantages: When charging using flash charging, the heat will be transferred to the charging head, so it is safer.

Disadvantages: Due to the large current, a special charging head and data cable are required, so the cost is higher and the price is also higher.

Note: Flash charging technology requires a customized charger and is incompatible with other chargers. If you use an incompatible charger, it will not only damage the battery, but also greatly reduce the charging efficiency.

In summary, we know

Flash charging technology charges faster

Fast charging technology has stronger compatibility

Recommendations based on different needs and mobile phone brands

How to charge your mobile phone safely?

Do not cover while charging

When the phone is charging, the voltage is in standby mode, which causes the phone to have a high temperature. If the phone is covered with something while charging, it will affect the heat dissipation.

Don't play while charging

Playing with your phone while charging will keep the charger in working condition, which may cause aging and even lead to accidents such as electric shock, fire, and explosion.

Do not charge for a long time

Mobile phones usually use lithium batteries, which may release a large amount of electricity instantly under special temperature and humidity conditions, causing spontaneous combustion or explosion.

Prevent water or moisture

The battery may short-circuit when it comes into contact with water. Before charging, check whether the battery and charger are damp or have water infiltrated them.

Unplug the power supply immediately

If the charger is not unplugged for a long time, it will continue to generate heat, which will accelerate the aging of the material and cause a short circuit.
