The mouse would need to have a battery monitor built in internally so that it could send the battery status to an app on the PC. I have never come across a mouse that has that type of circuitry built in .. my own wireless mouse starts playing up when the battery gets low .. normally only shows an up/down action on the screen and battery replacement brings back the horizontal movement ..

 

I've attached an image from inside my Synapse. As can be seen, it does keep track of the battery. I just want a way to see that, but on my tray. It does have the option of having different lighting when it's low battery, but I hardly look at the mouse when I'm using it so that doesn't really help me.

Logitech mice have a monitor that works well IF you can keep the driver working right all the time.

Unfortunately, I doubt it will help with my Razer mouse...

I see no tech details about battery monitor on their site .. I would suggest you ask if the mouse firmware supports battery monitoring and whether they have an app to go with it.

Remember though that running an extra app on the mouse will drain the battery quicker due to the extra work involved.

Also remember that whilst running in wired mode the cable connecting the mouse to the computer will be moving a lot and the disadvantage of this apart from an annoying cable on your worktop is that the wires inside the cable bend, twist and turn .. resulting eventually in cable failure and possible internal connection failure where the cable connector flexes the soldering at the board.

Charging dock
When you need to recharge the Razer Naga Epic Chroma or just display it when not in use, pop it onto the supplied sleek charging dock/wireless receiver.

 

Get in the habit of charging the mouse when it's not being used and monitoring shouldn't be an issue.

Otherwise, you likely need to contact Razer to see if that function is supported. I have a Razer as well, and I've not seen a way of monitoring separately.

 

I do. It has a long battery life so I don't really need to worry about it, but I still do. It just bugs me.
