I'd guess it's some kind of firmware bug or a pretty rare hardware issue. Since it shows the 1.6v there while turned off, aka in standby mode, it must either be setting that pin up correctly as an input or it could just be internally disconnecting it and leaving it floating. Then when it powers up, it's setting up that pin and getting it wrong, or it could be something in the hardware of that pin causing it. A protection diode or switching FET that's gone bad in there.
If you can reinstall the MCU, I'd just inject 1.6v into that divider line and then power the thing on and see what happens. If it showed full battery, then Id' try to update it, but if it's a hardware issue in there it'll just default back to the 0.6v again.

Thanks for the quick reply RDC! I tried RESET, but it didn't help. I can't do a firmware update because it won't allow it due to low battery capacity, even via cable. (I tried this: https://controller.dl.playstation.net/controller/lang/en/fwupdater.html)I checked the PCB with a thermal imaging camera to see if I could see anything strange, but I didn't see any parts heating up that would indicate a short circuit. I did a reflow on the MCU to see if that helps, but it didn't change the situation. I finally took the MCU off the PCB to see if I could see anything underneath, but nothing. The trace from the battery connector is continuous all the way to the pad under the MCU. The pads are not damaged at all. I really can't think of anything else but that the MCU has failed, but I find it very unlikely that everything else is working fine, the only problem is with the battery charge level measurement...

JDM-055. Initially, everything was OK, then I pressed the USB port for better contact and after that the joystick stopped being detected (strangely). The 5V, GND lines are ringing, D+ D- are ringing from USB to the inductors on the main board too. The joystick is not detected by the computer. I replaced the SPG chip. The situation is the same. 5V is supplied to the chip. Is there a 3.2V output. Should there be any other voltages when connecting USB, or am I looking for the wrong one? I changed the USB-pcb, I ribbon-cable too - the result is the same Main CPU dead? But battery does not charge

That line should be an Analog input only and not act that way, the dropping to 0v one. That trace makes a straight shot to the MCU, so it seems like it may have something really odd going on with it.
Tried holding reset for a bit? See if there is a firmware update?

Hello, I have a very strange problem. I have a PS5 controller equipped with a BDM-010 motherboard. The issue is that despite the battery is 100% charged, the MCU sees that the battery is completely discharged. I tried via Bluetooth and cable, same result. There is a voltage divider consisting of 150K and 100K resistors at the positive terminal of the battery connector. I measure 1.664V at the output of this voltage divider with a 4.183V battery voltage. I noticed that when I turn on the controller, this 1.664V drops to around 0.6V. I took out another properly functioning controller and measured it as well. Surprisingly, even after turning it on, I still measured 1.664V at the output of the voltage divider, so the voltage didn't drop after powering on. What do you think could be the problem? Could the MCU be at fault? Everything else works, it just doesn't read the battery level correctly. https://ibb.co/3hTb2hC

There are 4 solder joints under the R3 button, 2 are 3.2v, the other 2 are the R3 button line. Just pick 2 that are opposite corners from each other, like the top right and the bottom left ones, and there you go, duplicate R3.

Hi everyone, I bought a refurbished PS4 controller from GameStop and after a while it stopped working. I checked and in addition to the broken flat, a capacitor is shorted and two resistors are burnt. I searched the forum and found only the wiring diagram of the JDM-055. I would need the wiring diagram of the JDM-030 to see which capacitor I should use and which resistors. Does anyone know where I can find the pattern or does anyone already have one? Thank you so much for your help and your time. Bye, ema21

AliExpress
Ah ...maybe is fake, I had bought a retimer for an xbox that had no video signal, but the chip was fake

It was used? Or AliExpress?

Check resistor on connector battery, maybe them are short
