When playing Zelda: Breath of the Wilds on the Nintendo Switch, when I play with the Switch docked and the Joy-Cons physically disconnected, the left Joy-Con frequently "lags" or becomes disconnected from the Switch base unit altogether.
When the left Joy-Con lags, the Switch acts as though whatever input I had been using was still being held down. For example, Link will occasionally keep running briefly even after I release the analog joystick.
Only the left Joy-Con has this issue. The right Joy-Con always stays connected and has no lag issues.
The issue doesn't occur when the Joy-Cons are attached to the Nintendo Switch base unit itself.
The left Joy-Con does seem to work ok when it is within about 3 feet of the Nintendo Switch base unit, and there is no line-of-sight obstruction between the Joy-Con and the Switch
I have applied the "day one patch" to the Switch, with the Joy-Cons connected to the base Switch unit as the patch was applied.
Upon researching, this issue is has been widely reported on gaming news sites. (Refs: 1, 2, 3)
There's also an article on the Nintendo Support site about general Joy-Con wireless connectivity problems. However, that article doesn't make any mention of the problem specific to the left Joy-Con.
My question: How can I resolve this intermittent wireless connectivity problem with the left Joy-Con?
Best Answer
This is a known design flaw which is only effecting early models of the Switch.
It's something to do with electrical shielding (or something technical).
First try these steps to make sure you are using the Joy Con correctly
Joy Con Not Responding or Responding Incorrectly When Used Wirelessly
If that didn't work, talk to Nintendo and they will "fix your problem for free" - which means you send in your joy con and they fix it and send it back. This can take up to 2 weeks.
