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.

Since two known-good batteries work in another controller and this one runs normally over USB, the fault is likely somewhere in the battery power path. Seeing 4.1–4.2 V at the connector confirms voltage is present there, but it doesn’t show whether the voltage reaches the board correctly under load.

Since replacing the DA9087 didn’t change the symptom, I’d check the battery connector and trace the battery positive and ground paths toward the power-management circuit. Look for a damaged connector or joint, an open fuse or zero-ohm link, or a fault in the battery sense/temperature line. If you have the board view or schematic for this board revision, compare continuity and diode-mode readings with a known-good board. Also check whether the battery voltage drops when you try to power the controller from it.

What’s the controller’s board revision, and does it show a charging indicator or report a battery level while connected by USB?
