Wireless has gotten pretty good over the past few years. I have a super cheap wireless mouse from Aliexpress that I use to control my PC while I'm on my couch (I have the PC plugged into my TV to watch Youtube videos and play the occasional game) and I only have to charge that thing every 2 months or so for like 20mins. The much bigger problem is the annoying latency and random connection breaks, but that might just be a factor of the mouse being super cheap.
My keyboard does both wired and 2.4ghz wireless with a physical toggle and it's super reliable, but I have no idea how long the battery would last because I use it wired for my work Laptop during the day and wireless on my couch at night, so it's basically always at full charge.

It only works well because you have a super cheap wireless mouse from Ali. I have a fairly expensive wireless mouse from Logitech and I have to use it in Bluetooth mode to get less stutter because the USB port on my display, literally 10-20 cm from the mouse, is angled the wrong way and apparently the Logitech unifying receiver is DIRECTIONAL but not by design.

I use one on my main computer. It still works while charging, and even on Linux I get a notification when the battery goes under 10%. I plug it and use as a wired mouse for the day, and maybe leave it charging overnight and unplug it in the morning. Had it for 8 years now, never an issue.

This is the way.
