I also have drift (maybe?) issues. One of my lefts will sporadically slam forwards and won't register anything else for like 1/4 second which is pretty horrendous in Splatoon. BoTW/Picross eh. One of my rights will pull left until I do a bluetooth re-pair and calibrate. I find it odd that neither of them are consistent? Like why only sometimes, and why the one for a split second and the other until something is done about it?

I've been meaning to get electronics cleaner to test.

I've done a fair bit of testing with mine, have even modded my left cons with antenna extensions. There are two issues at play; first, the analogue sticks are crap and a bit of dust, human adult usage, frequent usage, or some combination of the above, makes the sticks register even when they're not being pressed. This results, for example in; if I put the Joy-Con down on the table while in the eShop, it'll bounce around every item all by itself. if I'm in a game, it'll keep walking in a particular direction until i flick/tap/move the stick to stop it.

The second issue is the signal one (hence the antenna mod). I'm an adult male with large hands (I can practically hide an entire Joy-Con in one hand). If you close your hand over it completely, it'll drop signal (the left on in particular) because it has a PCB antenna instead of the off-board antenna like the right con, it also doesn't help, that if you touch the metal strip on the con, you likely ground the signal as that strip becomes a shield; In normal use the metal strip is oriented to the open part of your hand, but with large hands, you're going to touch it anyway.

This second issue with signal loss, causes a very similar effect, in that (usually) the last direction pressed before the connection dropped will continue until it is reconnected.

Did the antennas help? Of the four, my original right is the worst with signal. The new pair has the drift issues while the original pair still has no drift issues. The new left one is the one that sporadically drifts whereas the new right one is the one that is consistently OK until after coming out of sleep.

As you can see, playing with reliable controllers now requires a bit of a decision tree navigated via the controllers current moods...
