BSI(battery save indicator )
its a charge information from battery to UEM
that how much battery have been fill.....
if this pin open or short then battery cont provide
charge info" to set......and then set show this
type of information (not charging)(charger not sported) etc

this pin also detected sim
and in all dct4+ and bb5 family if this pin disable
set will not power up.....
bsi function always deal power ic(uem)(retu)(avilma)

u can easily check this area by schematic just type
bsi in search bar and trace the fault from battery to power ic
