Charging Magic Mouse 2

I bought a new iMac (Catalina, v. 10.15.5) a couple of weeks ago. A couple of days ago I got a "low battery" notice - battery was at 4%. Charged it 14 hours and it only came up to 21%. Then yesterday charged it another 14 hour and it charged for 13% to 17%. Something seems wrong? I think I am doing everything right - not that complicated. Leave mouse power on & plug in. However, I do shut down the computer. Does the computer have to be open for the charging to work?

iMac, OS X 10.11

You said ”However, I do shut down the computer.” Shut down means powered off. For charging, the Mac can be asleep (screen blank), but it must remain powered on, not just plugged into a power outlet.

If your computer is, indeed, only asleep, but powered on, and your mouse is not charged after four hours, then it's not normal. The mouse should be fully charged after that period of time.

To test if the issue is with the mouse battery, try charging it via another method, as suggested above. Also, if you’re plugging the mouse into a USB hub, rather than directly to the Mac, most USB hubs do not carry power, or only one of the ports is powered.

Yes, USB ports are powered only when the Mac is on.

FWIW. You can use any other wall charger you have around, from your iPhone, iPad, etc.

Also, nowadays, desktop macs are usually left powered around the clock. Mac OS performs many maintenance tasks when otherwise not in use, most often during the night.

I'm not clear with this response. I never completely turn off my Mac (power off). My question was ( and I am not probably) not using the correct terminology). Does the Mac have to be open (not shut down) to charge. I assumed it would charge when "shut down" but it charges very slow. Just recently the mouse was charged 2% after being pluggged in for 4 hours. Is that normal?

Wow! Thanks! Left my iMac Powered On (in sleep) and the mouse charged to 100%! Strange, that not a single Apple instuction said to do it that way. I would shut-down my iMac and then plug in the charger. Assumed that even with it shut-down it would charge. Which it did a little.

As mentioned in my first post, most users leave their desktops powered on all the time.
