What causes the phone to disconnect when charging?

Reasons for phone charging interruption:

1, poor contact. Plug it in the other ports a few times to see if this happens.

2. The charger has a problem. Change the adapter or connect the computer with a cable to charge.

Charging is a Chinese term referring to the process of replenishing a device such as a battery. The principle is to let the direct current pass in the opposite direction of the discharge to restore the active substance in the battery. Now, it has an extended meaning such as study, work and so on. The process by which the battery receives electrical energy from the external circuit and converts it into the chemical energy of the battery. After the battery energy is consumed by discharge, it can be restored by charging, and it can be re-discharged to form a charge discharge cycle. Charge with DC current. In different cases, different charging methods are used, such as constant current charging, constant voltage charging, floating charging, trickle charging, rapid charging or the combination of these methods. According to the formula of power = voltage * current * time, in the case of fixed power, the charging time can only be shortened by increasing the voltage or increasing the current.

Mobile phone battery fast charging is mainly divided into three categories: VOOC flash Charge fast charging technology, Qualcomm Quick Charge 2.0 fast charging technology, Mediatek Pump Express Plus fast charging technology. Mediatek's new fast-charging technology, the Pump Express, is built into PMIC's power management integrated circuit. The charger is allowed to determine the initial voltage required for charging according to the current, and the PMIC sends a pulse current command through the USB Vbus to the charger, and the charger adjusts the output voltage according to the command, and the voltage gradually increases to up to 5V to achieve the maximum charging current.
