Member: 2782515 Status: Offline Thanks Meter: 0 | Redmi 4X attempt to resurrect The battery connector port gives 2.6V reverse polarization voltage so battery charger circuit works i guess. The only issue I found out is the power supply ic - pm18952, heats up almost immediately to 80 C is it normal, or IC is dead? Is there some test pads that I can check ? Should I try with new battery or it is pointless ? Any schematics available for pcb (Redmi 4X Global Version Snapdragon 650 based). Thanks in advance for any suggestions. |
