For what it's worth, it's possible to use joycons with a PS4, if you have the appropriate adapters and chain them together just right.
- The PS4 controller's range is VERY limited, even playing crouched on the sofa with your legs interrupting LOS between the console and the controller can cause connection issues.
- The Switch's tiny split controllers (the JoyCons, though there is also a traditionally-shaped Pro Controller) have very good reception, and being small and split means your arms can be in different positions.
I sometimes play lying on the bed with the console on a stand in front of me, and my arms under the sheets, when it's cold, for example. It's a tiny thing but is mighty convenient when you feel like it.
Odd, I’ve never once experienced any sort of issue like this with my PS4 controllers.
Makes me wonder if there could be something else environmental going on, or if I’m just lucky…
EDIT: Just double checked and they use Bluetooth with no obvious need tor maintaining line of sight? (I should have remembered this as I’ve used my PS4 controllers with Raspberry Pis over Bluetooth before). So I guess localised radio interference will have the potential to affect range.
In any case, the Switch's controllers fared much better, even though both consoles were on basically the same place. YMMV, I suppose?
Not to say the PS4 controllers are good... they just love to drain their batteries when I'm not using them, and they only seem willing to charge on the PS4 and only when its in sleep mode. TBH this hassle makes me use the PS4 pretty much never, which makes the problem worse
