For the most part it has worked great. But twice now I went to turn on my PS5 with the controller and it wouldn't. Somehow it lost charge overnight, while it was turned off. So I'd have to turn on the PS5 using the console and charge the controller up. The first time it happened the battery was low before I turned the console off for the night, the second time when it happened I had it plugged in for a few hours the previous day while I was playing so it should have been at least partially charged.
I don't know what's going on but I've got a year to get it replaced so for now I'll deal with it.
The odd thing is though, is that the battery lasts a long time when I'm actually using it, so I don't know why it would be losing charge overnight while it is shut off. I thought it could be syncing issue but it's not, the battery is definitely dead.
