I don’t game and don’t have any issues so far.
I did have some charging issues with NOS 3.0beta where the charging speed would differ when the cable was inserted with the screen locked or unlocked.
It was capped at 12W when the screen was locked and 28W when it was unlocked. This was with a PD3.0 PPS-enabled ANKER charger (Nano 3 (511)) that I picked up for £10.
Hopefully that is fixed. Otherwise, it’s been stellar on beta and that’s a very minor gripe.
