DualSense Edge poor battery life is because of a much smaller battery

A teardown of the DualSense Edge PS5 pro controller by Budd’s Controllers has revealed that Sony’s latest and greatest gamepad has a much smaller battery than that of the regular DualSense. We’re talking a 33% reduction in battery size and capacity, which is the culprit for the poor battery life in the high-priced controller.

Now it makes sense why they included a nice, long 2.8m USB cable in the package!

How much smaller is the DualSense Edge battery?

Australia-based Budd’s Controllers conducted their teardown live on Twitch, revealing the innards of the DualSense Edge, with Sony accommodating new trigger stops and back buttons on a gamepad that, externally, is practically identical in shape and size to the original DualSense.

That, however, has had a big impact on how big the rechargeable battery built into the controller can be. Sony hasn’t trimmed the battery size, they’ve had to make a dramatic step down in capacity, going from 1,560 mAh in the stock DualSense to 1,050 mAh in the DualSense Edge. That’s a whopping 33% drop, and you can absolutely see the difference.

How long is the DualSense Edge battery life?

During our DualSense Edge review, we were able to get pretty much exactly 6.5 hours for the DualSense Edge battery life. This was while playing plenty of intense PS5 games that make the most of the controller’s haptics and adaptive triggers – Ratchet & Clank: Rift Apart, for example – and gaming the entire time with a wired headset plugged in.

That’s a pretty tough test for the controller’s battery, with the pre-launch estimate of battery life putting it around 5-10 hours, depending on features used.

By comparison, we got around 9 hours from the DualSense during our original PlayStation 5 controller review, though we’ve seen other reviews giving around 12 hours of use before the controller conks out. This figure can and will deteriorate with years of use.

How does the DualSense Edge battery life compare to other gamepads?

Sony’s controller battery life has generally been lower than that of Microsoft and Nintendo. Let’s see how the official ratings compare:

  • Sony DualShock 4 – 1,000 mAh – 6-8 hours (unofficial)
  • Xbox Play & Charge Kit – 1,400 mAh – up to 30 hours
  • Xbox Elite Series 2 – 2,050 mAh – up to 40 hours
  • Nintendo Switch Joy-Con – 525 mAh – approximately 20 hours
  • Nintendo Switch Pro Controller – 1,300 mAh – approximately 40 hours
  • 8bitdo Ultimate Controller – 1,000 mAh – 22 hours playtime

All of these battery life estimates are dependent on how the controller is used. Motion controls on Switch and PlayStation controllers, large amounts of rumble, and bonus features like loudspeakers, IR sensors and NFC will all impact battery life if used heavily.

Is it worth it, though?

At £210, the DualSense Edge is a very expensive controller, but it comes with a lot of great features for gamers that want to get… an edge in gaming. There’s trigger stops, there’s a pair of back buttons, customisable analogue stick acceleration curves and replaceable stick modules, and plenty more.

In our DualSense Edge review, I wrote, “The DualSense Edge is an excellent first pro controller from Sony, the direct ties to the PS5 software and the familiar DualSense form making it a prime option for PlayStation gamers. It’s a shame that it and the emerging third party alternatives are just so damn expensive.”
