Cobra Pro/2.4 Dongle Problem | Razer Insider
Skip to main content

My mouse doesn’t last very long and randomly disconnects from the 2.4 dongle. The battery life of my mouse doesn’t last long only for 2-4 hours, when I turn off the mouse and plug it in, it charges then stops. For the dongle it would turn off or stop connecting to the mouse, I would have to plug the mouse into my PC then unplug and replug the dongle it starts working again but the battery on my mouse is lower than before and dies fairly quick after that. I have updated all razer software and made sure it wasn’t software problems, by disabling razer.
