today i was using my mouse just normally it wasn't plugged in or anything and i was using the usb blue tooth and the mouse definitely had charge. about 2.5 hours to 3 hours in the blue tooth just stopped i tried pugging it in to a different port and all it just stopped. when plugged in it shows up on razer synapse and tells me the amount of battery and its 90% i even tried to do an up date and synapse does not detect the usb so i cant even update it so it is most likely the usb. what should i do is there a fix or should i just send it back and get a replacement.
