Dualsense mod with back paddles and hall effect sensor problem

So i decided to mod my BDM-010 controller with Tomsin back buttons and chinese Hall effect analog sticks. It seems to work simultaneously, but usual jittering on analog stick is much worse than without back paddles. My guess is that 1.8v line overloading/interfearing/approaching it’s limit with both of this mods. Is there a way to solve this kind of problem?
Im kinda confused here because stock dualsense analogs use same 1.8v as far as i know and they are work fine with back buttons, so there is basically no difference in terms of power consumption.
Would be appreciate any help on this matter.
