DualSense

Power

Problem	Solution
PS5 controller does not charge	If the PS5 controller does not charge, check the capacitors around the DA9087 chip, if they are short-circuited replace the DA9087 power management chip. Credit goes to My Mate VINCE, here is video of his finding https://www.youtube.com/watch?v=OKs5DsDVNI8
Controller doesn't turn on when powered from USB	Check the battery, Dualsense requires the battery to be connected and functional to work over USB

Inputs

Problem	Solution
Controller analog drift (move by itself in-game)	There are four pots, two for each analogue stick. They should be cleaned first and if they are used up, then replaced, the whole analogue stick with the mechanism can be changed or only the pot. There are two types of sticks used, green pot ALPS, and orange pot. You can only swap green to green and orange to orange due to shaft size. See Fig 1. These pots will likely not center properly after replacement, you have to rotate them before soldering them in the correct center position, on PCBs without plated through holes you can bend over the pins to make this easier. In extreme cases you will need to shave the corner locating pegs.
Controller does some things alone (in the game it enters the inventory itself or the character jumps)	clean the contacts on the board and foil and add some material like foam under the foil. See Fig 3, 4, & 5.
R2/L2 doesn't return to 0 or feels weird/crunchy	Broken spring, common problem of early revision. You can replace this spring, you can also use the DualShock 4 spring.
