Member: 1212133 Status: Offline Thanks Meter: 58 | LG G3 (D855) power supply instead of battery My problem is that the battery has 4 pins ( +,?,-,?). The first positive voltage , next unknown function for me, next is negative voltage and the last is unknown function for me. I connected positive voltage ( +) from a power supply to the mainboard + pin( exactly the same where the battery has the + pin.) Also connected negative voltage from power supply to negative pin on the mainboard. But G3 dos not start. So I would guess I need to connect somehow other pins on the mainboard with power supply Does anyone know how? Thanks |

(3v~3.3v) <-- measured on my tester,,this pin tell the phone it has a battery pin3 (-) <-- ground pin4 (bsi) <-- this pin determines the status of cells voltage capacity ,,you can power up by supplying pin1,2,3 but afterwards phone will shutdown (invalid battery) ,,pin4(bsi) must have correct voltage |
