Dualsense TMR Upgrade - Process Video

A start-to-finish look at a DualSense TMR stick upgrade, the permanent fix for PS5 stick drift.

The stock PS5 sticks track movement with parts that physically rub against each other. Over time they wear down, and that wear is what causes drift. Swapping in another set of stock sticks only resets the clock. TMR (tunnel magnetoresistance) sticks measure movement with magnets instead, so nothing rubs and nothing wears out.

In the video:

• Opening up the controller and taking it apart down to the main board
• Desoldering both original stick modules and cleaning up the pads
• Soldering in the new TMR sticks
• Putting it back together, then testing and calibrating it so both sticks centre perfectly

The result is a controller that feels smooth and precise, and won’t drift again.
