PS5 Dualsense does not work on battery

Hi,

I’m having a problem with a PS5 DualSense controller that stops working when running on battery power. I’ve tried two known-working batteries from another controller, and both work fine in the other controller.

I’ve taken measurements at the battery connector, and it reaches around 4.1–4.2V. I also tried a battery charged to approximately 50%; its voltage increased from around 3.8V to 4.1V, so it appears to be charging correctly.

The controller works perfectly fine when connected via USB cable, but it won’t operate from the battery.

I’ve also tried replacing the DA9087, but nothing has changed.

Answer this question I have this problem too
