As we all know, Sony’s DualSense Edge is undoubtedly one of the best and most advanced gaming controllers on the market. It has countless features, such as haptic feedback, adaptive triggers, and a dedicated Share button. But one of its biggest drawbacks is its notoriously poor battery life.
For a while, the reasons why the DualSense Edge’s battery life was so poor were a bit of a mystery. However, a recent analysis from iFixit has shed some light on the matter.
Upon disassembling the DualSense Edge, it was discovered that the controller utilized a very large battery with a capacity of 5.6 watt-hours. This is more than double the capacity of a standard DualShock controller, which utilizes a 2.4-watt-hour battery. But it’s still not enough to power all of the DualSense Edge’s features.
In order to make up for the large battery’s limited capacity, Sony had to outfit the DualSense Edge with energy-efficient components, such as an ultra-low power ARM Cortex-M0 processor and a set of energy-saving haptic actuators. The problem with this is that although these components do make the controller more power-efficient, they also reduce its performance somewhat.
Furthermore, the DualSense Edge is also equipped with a number of extra sensors and antennas, which reduce its battery life even further.
Ultimately, the reason why the DualSense Edge’s battery life is so poor is due to the combination of its large battery and its energy-efficient components. While the controller certainly isn’t lacking in features and performance, users will have to be prepared to charge it frequently if they want to enjoy its full potential.
