Redmi 9C & octo4a schematic Redmi 9C does not support charging while connected with OTG cable to a printer. So I did decided to bypass the battery and provided power to the + pin and the middle of the 5 pins near the battery connector. The problem is that the battery is still getting drained. To which pins do I need to connect the power?
Pls change battery and check. If still same problem then check BAT ID line. Without battery should get 1.8v on the BAT ID line and when connect the battery the voltage should change to 0.5V to 1.2V. If not changing the voltage at BAT ID then repair that line.
did you change the IC sir
Yes, I changed the IC.
