This is likely a non-issue for you because you're responsibly recharging it on a regular basis.

Many people are not as responsible as you, and for them Murphy's law means they'll be mouseless at the worst time possible every month.

I have mouse battery anxiety and regulary check how much charge is left.

Can you truly love something that makes you constantly paranoid?

Honestly, the battery status is within reach of just a single mouse click in the Mac OS menu bar, I check it maybe once a week. I think there is even a warning when it reaches very low levels. In the rare case I forget to charge and run out, it is enough to charge it for like 15 minutes to keep working for the day.
