When playing with the Sony PS5 DualSense controller using your Bluetooth-enabled smartphone, tablet, or PC, you must manually switch off the controller when you’re done to preserve battery life. Here’s how to do it.
How to turn off a PS5 controller when it is paired via Bluetooth?
DualSense won’t turn off when you’re finished with the PS5 controller, even if you use Bluetooth. Even if you switch off your PC or phone, DualSense will continue to seek connection with the device it was linked to. As a result, the battery on your PS5 controller will be discharged unnecessarily as a result of this.
To turn off the PS5 DualSense controller, press and hold the PlayStation button for about 10 seconds.
You can check if it is off by looking at the lights around the touchpad. If they are no longer lit, the DualSense has been successfully turned off.
To turn it back on later, simply press and hold the PlayStation button for a moment until it turns on.
