The battery degrades.

My Magic Mouses battery only lasts for 5 to 10 minutes... if I could use it while plugged in I could still use it. As it is I can just toss it.

In practice, there is no problem to be solved here. I have used a Magic Mouse for at least five years. It has never run out of juice while I’m using it, and I simply plug it in at lunch or overnight or on a Zoom call for a bit when I start getting notifications about the battery. It runs for three weeks of daily use without need for a charge.

I've used a magic mouse for over 3 years, and I've never ran into a situation where I couldn't use it because it was charging. When I see the battery is low, I plug it in during my next bathroom break, and then fully charge it over night.

Because that will wreck the battery capacity.

Li-Ion batteries aren’t designed for that use-case.

Also the Magic Mouse has fast charging. You’ll get a full day of battery in 2min.

With a full charge, you’ll get 2+ months of usage.

Do the math. You’ll most likely charge this thing less than 20 times in it’s entire life.

That’s why the battery port design is both really smart and elegant. Unfortunately people don’t take the time to understand the purpose of design choices and jump to the easiest meme that reinforces their beliefs.


Because they didn't want you to plug in the lightning cable and just use it as a wired mouse ... because that defeats the purpose of it.

I mean, I plug mine in once in a blue moon ... and always when I leave the office for the night ... and it's fully charged for many weeks thereafter.

You might have more of a point if the battery only lasted a few hours ...


It's not really a big deal, I have a charger at my desk for my phone. So once every 3-4 weeks, I plug in the mouse when I leave. It's never run out of battery when I wanted to use it.

FWIW I use my Magic Mouse 2, 9 hours a day Monday-Friday. I’m pretty sure I don’t charge it more than once every 3 months, if not more

People still bringing up the Magic Mouse.

The idea is you weren't supposed to leave it plugged in.

2 hours of charging = 2 months of use so it's not like charging was supposed to be a regular occurrence.


I have several Magic Mice, including the one that still runs on the battery. I never had any of the batteries going bad - my oldest one is 5 years old at least still goes like a month on a charge.

That’s right but it still sucks when the mouse dies and you can’t do anything till you’ve charged it a bit.

It doesn't matter how large the battery is - at some point, someone forgets to charge. With any other mouse, you plug it into the charger and continue to use it while it's charging.

How often do you use it? Every person I know who has one typically has to charge it about once per week with a typical usage of about 8 hours per day. I have the original Magic Mouse with replaceable batteries, and I have the replace them roughly once per week.

Being able to charge it while in use might extend the life of the mouse past the life of the battery

Do you use an Apple mouse? It's not like you are frequently charging. Just plug it in while you go get a coffee or lunch and you are good for weeks. It displays a low charge warning in the menubar to alert you.

I found having to always keep a supply of batteries at hand was more inconvenient than just plugging in the mouse once in a while.


You can just leave these plugged in all the time if you never want to think about the battery again. Unfortunately plugging them in doesn’t make the MX Ergo be a USB mouse. It only charges the battery.

it has become a meme, but really a non-issue in real life if you used the mouse yourself really. A minute or so of charging is enough to power it for a whole day of use. plug it again when you leave your desk for a bit and you'll have enough charge for days.

If your mouse is the only device in your house that takes a lightning connector, why are you frantically trying to find the cable every time it gets low? Just keep the cable by your mouse. It’s not like you are using it for anything else. And why “frantically” anyway? The mouse gives you loads of warning before the battery goes, I routinely use it for hours after the warning. This is not an emergency.

The only time it was an ever an issue when I used one, was I plugged it in, I went to the bathroom, I got a coffee. And it was charged enough to use it until I could charge it for hours later.

The sleep cycle of a mouse microprocessor is 99.9%+. A few minutes charge will get you hours of use.


Nobody has to ‘worry about this stuff’. In the unfortunate case power runs out you charge the mouse for two minutes and you’re good for a day of use, after which you charge it completely and you’re good for months again. A complete and total non issue.

I can tell you that for me this is actually really annoying.

When my Bluetooth mouse runs out of battery, and I would just charge it for a couple of minutes and it lasts the whole day.

But end of the day, I almost always forget to charge it overnight. So the next day I have to repeat the process.

That's why now when it runs out of battery, I just use it in wired mode. And a while later I unplug it or whenever I realize it's in wired mode.

Yes it's a small thing but if you can implement it why not just do it? Or better yet, switch to AAAs and not worry about charge circuits at all?
