Battery Connectors 
This the interface where the battery connects and supply the voltage  to the cellphones main circuitry or PC Board. Old models used 4 pin which lead to four battery output sources such as +(positive) - (negative) BSI (battery status indicator)  and Btemp  (Battery Temperature)
The latest designs consists of only three pins, The + (positive) - (negative) and BSI  (battery status indicator) the Btemp is diminished and still in cellphone circuitry included.
