How to charge the new mobile phone battery How to solve the problem that mobile phone battery is not durable

How to charge a new mobile phone battery 1. The mobile phone battery is composed of three parts: the battery cell, the maintenance circuit and the casing. The current mobile phone batteries are all lithium-ion batteries (usually referred to as lithium-ion batteries in irregular situations), and the cathode material is lithium cobalt oxide. The standard discharge voltage is 3.7V, the charge cut-off voltage is 4.2V, and the discharge cut-off voltage is 2.75V. The unit of power is Wh (watt hour). Since the standard discharge voltage of mobile phone batteries is 3.7V, it can also be replaced by mAh (milliampere hour). The conversion relationship between these two types of units on the mobile phone battery is: Watt hour u003d Ampere hour × 3.7.2. Overcharge, overdischarge and short circuit will severely harm the performance of the battery and may lead to operational risks. For this reason, there is generally a slender maintenance circuit board in the mobile phone battery to prevent these risks. 3. The charger is divided into direct charge and seat charge. Dash converts 220 AC mains power to 5V DC, which is input into the mobile phone and the charging circuit of the mobile phone will step down the voltage to the battery. Generally, it will be delivered when buying a mobile phone. The charger is directly connected to the battery, and converts the mains power to the required voltage for the battery to use. 4. Assuming that you want to use a charger, please try to choose original or excellent quality products. If the charging circuit in the cradle is of poor quality, there will be a charging risk. 5. Lithium-ion battery has no memory effect, but it is inert. If it has not been used for a long time, it may be passivated. After a few times of charging, it can recover the best performance. 6. Before charging, do not discharge lithium-ion batteries. Some fast chargers only indicate 90% of the charge when the indicator light changes, and the charger will actively change to charge the battery with slow charging. But generally speaking, it can be removed as long as it shows overflow. 7. In order not to endanger the life of the battery, it is best to charge slowly when charging; the time does not need to be too long. The solution to the battery is not durable 1. Pay attention to the battery placement environment to prevent contact with metal materials, and place it in a comfortable and dry environment; 2. Turn off WiFi, GPS and other services in time. Most mobile phones support WiFi wireless network services and GPS global positioning service, although WiFi can let us enjoy free Internet service, but if you don’t need it, please turn it off, because the data exchange after we connect to WiFi will also consume a lot of power; 3. Using battery to optimize APP battery life is calculated according to the charge and discharge cycle, the longer the cycle, the longer the battery life. DUBatterySaver has a deep power-saving function, which can end some useless applications and processes, and achieve the power-saving effect, thereby extending battery life; Disclaimer: Some pictures and content of articles published on this site are from the Internet.
