Four major characteristics

1. Battery capacity: cell phone battery is used to provide mobile phone power, which is its most important function, so the measure of a battery is the most important point is the battery can store the amount of electric energy. In technical jargon is the battery capacity.

2. High functionality: Due to the wide variety of mobile phones on the market, some mobile phone manufacturers add some circuits to the battery due to some reasons, such as charging circuits, information storage circuits like battery ID cards, temperature detection circuits, built-in vibration motor circuits, Dual SIM circuit. . . Wait. These circuits play a special role in the battery into the cell phone, which is the cell phone battery functionality.

3. As the phone is in the hands of the user is non-stop use, so the battery in the hands of the user is also kept storing energy, the release of energy cycle process, which is usually referred to as charging and discharging process, all batteries have a certain Charge and discharge cycle life, with the constant charge and discharge cycles, the battery capacity will gradually reduce, until low can not be used, and a battery from the original high capacity after repeated charge and discharge process, its capacity is reduced To only 80% of its nominal capacity, during which the number of charge and discharge cycles seen as cycle life.

4. High security: Since cell phone batteries are basically composed of NiMH batteries and Li-ion batteries, due to their own special chemical, high temperature, short circuit and other conditions there will be an explosion danger, so it is usually necessary to add some inside the battery Temperature protection circuits, to avoid their danger in some environments, this is the battery safety.
