If you wonder why your shiny new DualSense Edge controller does not last as long as the standard controller, we finally know why. The DualSense controller has a battery life of around 12 hours, while the Edge controller barely lasts 6 hours on a full charge.
DualSense Edge Teardown Reveals Smaller Battery

In a recent teardown shared by Twitter user Budd’s Controllers, he revealed that the new PlayStation 5 controller has a significantly smaller battery when placed side by side with the old battery.
The battery capacity is smaller too, at only 1,050mAh (the original DualSense controller has a battery capacity of 1,650mAh). This might not be an issue to pro players, who prefers wired connections anyways, but still it is disappointing news considering the hefty RM999 price tag.
The teardown also revealed how cramped the internals of the new controllers are, with the back buttons taking up previous space that was previously occupied by the battery.

Considering the Xbox Elite Wireless Controller Series 2 has a whopping 40 hours of battery life, we can’t help but wonder why.
