Battery is the electric energy source of terminal devices, and if there is no battery, the application performance of the terminal device will be greatly reduced. A high-capacity high-performance battery can not only provide long duration capability for a terminal but can also protect the terminal, so that the terminal device can operate for a long time with high efficiency.
With the popularization of modern mobile phones, especially smart phones, the functions thereof are richer and richer, which have become necessary for user communication, office work and entertainment. Most people think highly of battery duration capability, 38% interviewees state that as long as the mobile phone can continue operating normally (such as dialing and answering, and receiving and sending short messages), they are satisfied and do not want to sacrifice the battery duration time for any additional functions. The data obtained from the after-sales market also demonstrates that customers do not satisfy with the service life of the battery being shorter and shorter and the charging efficiency being lower and lower to the greatest extent.
The reason that the service life of the battery becomes shorter and shorter may be: frequent and repeated high-potential charging and over-charging, battery over-discharging due to not be charged for a long time, etc. For common users, from the moment a terminal device is used, the performance of the battery will decrease gradually over time, and therefore, to retain the performance of the battery to the greatest extent means a lot.
