Nope. It kind of just went away and didn't return. To be fair, I only really noticed it when playing BF4 (Battlefield 4) competitively online. My gaming has reduced significantly to the point I only play a bit of Fusion Trials and Witcher 3 here and there. In both these games, I haven't come across the issue anymore. Witcher would be a bad example because it's a slower paced game as opposed to when I had the issue with Battlefield. Then again, I haven't played for those prolonged hours and rarely used the headset since, which, when I read this topic and my older post, was one of the things it required it to happen in the first place.
But I do feel that after my last post in here, it kind of went away. Not sure if this was due to an update or some other interference simply going away.
I'm not sure now, but I think I read somewhere that the Dualshock transmits its data over bluetooth irregardless if its plugged in through USB or not. The USB is only there to charge the controller.... Not sure if this is either accurate or true. Wouldn't make sense in regards to the latency issues being solved when plugged in. Unfortunately I never tried back then if it made a difference plugging in the controller into a USB charger or connecting it with a USB with the console... It would be what I would advice you to test though if you experience the latency issues on a regular, almost predictable basis. If it goes away either way, it may be power related. If it only goes away when connecting directly to the PS4, make note if it goes away because of you connecting it through the USB port or because you may have reduced the distance to your PS4. It could be due to either. That's what I would check for to pin point the issue...
