1. Bad charging habits: Bad charging habits are one of the main reasons for the decline of battery health. For example, frequent charging, overcharging and not using the original charger will cause damage to the battery.
2. Too high frequency of use: With the increase of frequency of use, the life of the battery will gradually shorten. Generally speaking, the service life of mobile phone batteries is about two years.
3. Software factors: Some applications will consume a lot of power, which will lead to a decline in battery health. At the same time, some system or software updates may also have an impact on battery life.
Mobile phone battery is an energy storage tool to provide power for mobile phones, which consists of battery core, protection circuit and shell. Mobile phone batteries generally use lithium batteries and nickel-hydrogen batteries. Lithium battery is a rechargeable battery, which mainly depends on the movement of lithium ion between the positive electrode and the negative electrode. Lithium-ion battery uses carbon material as negative electrode and lithium-containing compound as positive electrode. There is no metallic lithium, only lithium ion. In the process of charging and discharging, lithium ions are intercalated/deintercalated and intercalated/deintercalated back and forth between the positive electrode and the negative electrode. This process is vividly called "rocking chair battery".
