In recent years, with the development of science and technology, mobile phones have become more and more intelligent, and the charging methods of mobile phones have become more diverse, such as flash charging, fast charging, wireless charging... The time to fully charge a mobile phone is getting shorter and shorter, fast charging? Flash charge? There is only one word difference, are the two the same thing?
Fast charging and flash charging are not the same thing
fundamentally different
Fast charge: increase voltage, decrease current
Advantages: Because the current is low, the compatibility is strong, and there is no high requirement for mobile phone chargers and data cables.
Disadvantage: Increasing the voltage will generate higher heat, causing the phone to heat up and affecting battery life.
Flash charge: reduce voltage, increase current
Advantages: When charging by flash charging, the heat will be transferred to the charging head, so the safety is higher.
Disadvantages: Due to the large current, special charging heads and data cables are required, so the cost is higher and the price is higher. Flash charging technology requires custom chargers and is incompatible with other chargers. If you use an unsuitable charger, it will not only cause damage to the battery, but also greatly reduce the charging efficiency.
In daily life, you can choose the appropriate charging method according to different needs and mobile phone brands, and the problem of charging efficiency is solved.
And a little more about charging your phone
Did you master it?
Does the phone have to be charged to 100% every time it is charged?
It will accelerate the aging of the battery.
Leaving the phone in a full or high power state for a long time will accelerate the aging of the battery and make it less durable. Therefore, after the mobile phone is fully charged, the charger should be unplugged in time to avoid being in a high power state for a long time, so as to prolong the battery life.
But if you go to the other extreme and often use up the battery of the phone before starting to charge, then each charge will consume the number of battery cycles, and the phone battery will age quickly for a long time. The best time to charge the phone is when the battery remains 30%-50%.
After stopping charging, can the charging head on the wall be unplugged?
pull! Must be pulled!
Lei Yian, an associate professor at the School of Physics at Peking University, said after the experiment that as long as the charger is connected to the circuit board, even if there is no load, it will generate a certain current, some of which are small and some of which are relatively large. This is because the charger is a transformer and rectifier device. After it is plugged into the circuit board, it will consume a certain amount of current and be in a working state all the time.
If the charger is left on the power strip for a long time, it will continue to heat up, which will accelerate the aging of devices and materials, and easily cause short circuits and high-voltage breakdown, which will cause fire hazards.
The correct way to charge your phone
Do not cover while charging
When the mobile phone is charging, the voltage is in a standby state and the temperature is high. If the phone is covered with something, it will affect the heat dissipation.
Don't play while charging
Playing with a mobile phone while charging will keep the charger in working condition, which will cause aging, and even lead to accidents such as electric shock, fire, and explosion.
Turn on the power first, then connect the phone
The correct way to charge a mobile phone is to first insert the charger plug into the socket, and then plug the data cable into the mobile phone.
Do not use the computer USB to charge the mobile phone for a long time
Using the computer interface to charge the mobile phone for a long time will damage the lithium battery of the mobile phone and shorten the service life of the battery.
