Why are there more than two poles for a phone battery | Facts you know the first time about the phone battery.
The battery is considered a reservoir and a source of nutrition for the phone device. For the phone, the battery is one of its basic components and also the most common cause of problems. The battery consists of a positive electrode and a negative electrode, and between them there is a chemical substance in which a reaction takes place that makes it charge and another reaction that makes it discharge simply. This is the principle of its work.
This material consists of lithium-ion or this polymer lithium in new batteries, while the old ones are nickel-cadmium. Lithium is considered one of the best materials used for this industry because of its ideal for charging and discharging, but its only drawback is that it needs a smart circuit to charge it and Any wrong way of charging may cause it to explode because lithium is flammable and explosive.
: Why does a battery have more than two electrodes
An important question I have always wondered about, and one of these poles is a pole called the BSI, which is the pole for monitoring the battery’s work and temperature, which tells the processor about the condition of the battery as well as alerting it in the event of an error or defect in the battery and the fourth pole is the ID pole or what is called the battery identifier, but it can That the device works without this pole, but the third is very important.
:Phone battery features
The voltage of the phone battery is 3.7 volts, and in modern phones it is 3.8 volts, and the battery capacity is in milliamps and reaches up to 6000 milliamps in some modern devices.
:What is meant by charge and discharge cycles
The battery is a rechargeable cell and the charging cycle is the required value for the charging height from 1% to 100% or its consumption from 100% to 1%. Each battery has a specific number of charging cycles, for example, 2000 cycles. With regard to the battery capacity, we assume, for example, that we have a battery with a capacity of 2000 mAh. This means that if you withdraw from the battery 2000 mAh, the latter will run out within one hour, and if you withdraw 1000 mAh, it will run out. Within two hours, and so on, but we should not use the batteries until their charge is carried out. This makes them weak and will not last longer, and it is preferable to charge them at the 20% or 15% level.
: Phone battery malfunctions
Battery swelling is considered the most important malfunction that may affect the battery, and this is evidence of the expiration date of its validity or not being manufactured with high quality, The device works normally and then turns off suddenly the malfunction is the battery is not fixed in its correct position or the battery no longer stores enough energy. The battery is charged to a certain level (from 50% - 80%) and then begins a rapid gradual descent until the implementation of this battery is no longer valid and its internal materials have expired.
: Reasons for short battery life
One of the most important reasons for the short life of the battery is to use it until it runs out, as well as using it and charging is connected to it, as well as repeating the charging process, for example, when it reaches half, you charge it and it does not reach 20% using the phone until it runs out and recharges it again, the battery is full and did not disconnect the charger from it, displays The battery is due to weather factors (high temperature, humidity...) Extensive use of the battery, such as continuous playing, using the maximum brightness, turning on mobile data, WIFI and Bluetooth, and you do not need them.
