Sources say over 200 mini phone cell producers have been launched in China and that Changhong has been one of these to go in for mini phone cell production in Sichuan.

News reports also say that there were already 40 million mini phone cell users found in China last year, thereby giving rise to a profitable market for the product in the country.

By the standard of high quality mini phone cells capable of charging and discharging 500 times each, with every mini phone matched with two cells, the annual demand will be over 30 million cells, to a value of 6 billion yuan, and a market potential to over10 billion yuan.

Quality chips are indispensable for quality cell production. At present, almost all high-quality cell chips are made in Japan. Though Chinese cell producers still use Japanese name brand chips, yet they have got ahead of their cell imports in design.

Domestic mini phone cells still pose great appeal to mini phone users for their good after-service. Some producers have even made the promise that they will hold themselves "responsible to every cell" produced.
