Smart phone battery is not durable, with a long time will change the card, why?
Lithium battery charge in the process of chemical reactions will be lost, the general life of lithium batteries in two or three years, immediately, lithium batteries will lose capacity. And this process is irreversible. So the phone after a long time, the battery capacity will be smaller and smaller, while affecting the phone's performance with the play.
The battery has been a short cell phone, many mobile phone configuration up, but the cruising ability often can not keep up. The fundamental reason is that other mobile phone hardware is the physical field, and the battery belongs to the chemical, chemical development is much slower than the physical.
Batteries are chemical technology, and smart phones used in the process of charge and discharge of lithium battery chemical reaction occurs, there will be consumption, so the use of lithium batteries in a period of time after the capacity will slowly decline.
