What is the reason that charger damages the mobile phone battery?

Many users feel that charging the mobile phone with Charge Pal often damages the mobile phone battery. Some people say that since using the charging treasure, they feel that their mobile phone's power is getting less and less durable. It is also said that some people use the Charge Pal and the mobile phone often crashes and so on. Does Charge Pal really hurt the mobile phone battery? Why?

As we all know, inferior Charge Pal will certainly damage the mobile phone, but in fact, the regular Charge Pal may also make the mobile phone battery not durable.

Inferior charging treasure

1, poor quality circuit board

The Charge Pal is mainly composed of three parts: the outer casing, the electric core and the circuit board. The most important part is the circuit board. The advantages and disadvantages of the circuit board are directly related to the discharge effect and the conversion rate, which directly affect the charging effect of the device.

If the conversion rate of the Charge Pal is low (80% or less), then the Charge Palwill have a relatively obvious fever during the charging process, and the power charged by the mobile phone is likely to be mostly virtual power.

The instability of some charging treasures is also a problem with the board, because the buck and boost of the Charge Pal are regulated by the board. When charging a mobile phone, tablet, etc., the board adjusts the voltage of the Charge Pal according to the input voltage supported by the device.

In addition, overcharge, over temperature, over current, over voltage, under voltage, short circuit and other protection modules are on the circuit board, these are a must for a qualified charging treasure, poor quality circuit board cannot provide better protection.

Formal charging treasure

2, cannot trickle charge

As we all know, the whole process of mobile phone battery charging includes three stages: fast charging, continuous charging and trickle charging. After the first two stages, although the system power showed 100%, the battery did not actually reach saturation. The remaining capacity at this time can only be supplemented by a small pulse current. Trickle charging is a small current charging after the battery is fully charged, which keeps the electrons flowing and prolongs the life of the electronic device.

Most of the charging treasures have been disconnected from charging when the mobile phone has not entered the trickle charge of a small current. It is a relatively rough overcharge protection. If the mobile phone is not pulled out in time, the battery will continue to be charged when it is discharged to a certain extent, but it cannot always be fully charged.

Because most charging treasures only support more than 0.1A charging current, less than 0.1A, Charge Pal will think that the device's power is full and it will not enter the charging state. For example, cannot charge the Bluetooth headset.

Although the Charge Pal can't make the mobile phone enter the trickle charge, it will not cause obvious damage to the battery, but the trickle charge can extend the battery life. There are also some charging treasures on the market that support the charging of Bluetooth headsets. It depends on how much charge current is supported by the charging treasure. Mi Charge Pal supports 0.06A Bluetooth headset, GreenLink Charge Pal minimum current can detect 0.04A. They can support most of the Bluetooth headset charging on the market. At the same time, it can also meet the trickle charge of mobile phones to a certain extent, and has overcharge protection.

3, while charging

When some friends travel on road, they need to charge when the mobile power and mobile phone need to be charged, and the socket or charger is not enough, they will want to charge the mobile phone while charging the mobile power. In fact, most mobile power supplies are not recommended. The main problem is that this will cause the board to be heavily loaded and generate excessive temperatures in a short period of time, thus affecting performance and security. If the input value of the Charge Pal is 5V/1A, and the output value is 5V/2.1A, it is easy to form a phenomenon that cannot be used. The internal parts of the Charge Pal will be greatly damaged, and the Charge Pal will be affected after being injured. The phone is gone.

If you want to use it while charging, you should choose a mobile power source with a current input value greater than or equal to the output value. In addition to basic protection, it is best to have an independent temperature sensing probe inside, which can be very safe. .
