Sony is reportedly set to release an updated PS5 DualSense controller with a removable battery | VGC

Nice change. But it's probably because of the EU making it mandatory more than Sony being good guys.

God I hope so. My DS5 battery died within a year. It literally loses a full charge overnight, and even when it still worked it only reported battery percentage in 12% increments. My still-chargeable DS4 was still accurate to the 1%.

I still use the DS5 wired because screw e-waste, and ergonomically it's adequate. But the battery problem makes it the worst controller Sony's ever made, and I'm including SIXAXIS in that assessment.
