I use a wireless mouse by ASUS for on-the-go which I like a lot. Its scroll wheel is broken, but this mouse has long been discontinued and I have yet to find a comparable replacement.

@volpeon I've been facing the same issue with my desktop mouse. Finding another light minimalistic wireless mouse with four buttons and a wheel, that doesn't have RGB but does have a month-long battery life, good wireless performance, and wireless charging has been impossible. The switches died almost immediately out of warranty, but I soldered on better ones and am fully intending to ride it out at the very least until there's a breakthrough in mouse technology or something.

@volpeon Scroll-Wheels the end boss of every mouse-vendor....

@volpeon I use Razer Deathadder V2 Pro, it has microUSB, Bluetooth and 2.4 GHz USB adapter, can remember two (or three?) Bluetooth devices and the battery lasts about a week with 8-hour daily use. You can also get a docking station to charge it, if you want, or use the microUSB cable provided.

Bonus points: you can turn off RGB from the (optional) software.

I have been using it for almost three years now and I can definitely recommend it.
