Things like this dumb mouse and how it is created are most likely created like that on purpose. Not sure what that purpose is, but it is. I'm pretty sure a massive company like apple know this is a very dumb product.
The purpose is they don't want users to leave the mouse permanently plugged in. That would leave an ugly wire to their beautiful wireless product. in my opinion the only pointing device apple ever got right was the trackpad. Their mice have been absolute crap since the iMac g3 hockey puck mouse days. During the G4 era they had that transparent pill looking mouse, then the pill with the ball scroller that would collect hair. Then magic mouse and now this. Consistently bad since the early 2000s is actually quite impressive.
Desktops in general don't make sense for apple. it would only make sense if they were a tech company but they are not they are a Luxury Fashion company. it's not about what you do with your computer it's how you look doing it. Apple has more in common with Louis Vuitton than HP
They want you to buy two mice so your $40 wire can be charging your $90 shitty magic mouse that can't be used when it's charging because the ports on the bottom.
I worked on a place that had one of those and it sucked ass. I solved the problem using a 5 year old mouse that I payed 20 dollars and changed batteries every 1.5 years.
They gave us one at work, so I have one for that, but I really don’t like using it. I actually wanted to like it, but I just don’t like how it functions. I feel alot more wrist fatigue from using it and find myself accidentally clicking with it more often when I don’t intend to. There’s also some specific software we use that doesn’t play nice with it. Mine just uses batteries though, so I don’t have the charging issue. I really only bring mine around as a spare mouse, if for some reason I don’t feel like breaking out my ridiculous swiftpoint Z gaming mouse that I normally use.
I think that one of the issues is weight. Batteries add an awful lot of weight to a mouse. If you use a wired mouse, it's unbelievable how light it is. That could definitely improve your wrist problems.
Nothing worse than a light mouse though.
This is legitimate criticism of the mouse. I don’t like it for the same reason: I had carpal tunnel issues with it, as well as unintentional swiping and clicking issues. 
Just charge it one of the 10 times it tells you the battery is low as you leave the office, and you won’t have to deal with it when the battery actually dies. It’s not that complicated.
What if it needs charging in middle of work?
Plug it in for, like, five minutes and go take a pee break. It’ll be good for about six hours.
