I have a MacBook Air 2019 and I have noticed that there is no low battery warning/notification at any time. Shouldn't there be a low battery warning when the battery reaches 10%? If not, is it possible to create a low battery warning? I'm running macOS Catalina 10.15.3.

Mine has one but only when it gets very low like 5%.

Or it might be 10% I cant remember, but there definitely is at least 2 warnings before it dies.

Ah, thank you for that info. I never let mine get that low, so I never saw those low warnings.. I always plug it in when it hits 10%. It's nice to know there actually are warnings.
 
Yes, I get it at 5%. The machine slows down considerably and is almost unusable by the time it gets to 5% anyway.

Not only is there a notification window, the battery icon in the menu bar will change to red.

At least with their own Bluetooth peripherals (Magic Mouse 1 & 2, Magic Trackpad 1 & 2), there are also low battery alerts.

I'm pretty sure the low battery notification has existed through the entire history of OS X/macOS. It's a critical feature for a notebook computer.

i haven't had a low battery warning since around the time of Mountain Lion. i got a new Mac/MBP which came with Mountain Lion and suddenly my computer started dying without warning. i went to the battery in menu bar to set my preferences for when i wanted to be warned and how many times and those options were no longer there. That had to be a mistake, why take that away? i called Apple Support and was told they don't have it anymore. i got a 3rd party app which worked good but those never could keep up with the fast changing Mac OS anymore. i finally just bave been living wiht it and it makes me really mad. It's user UNFRIENDLY. so i was surprised to stumble onto this link and people saying in 2020 that they have always had low battery warning. i don't see anything in Energy settings related to any warning or alert. i got my first Mac, a Quadra 605, used, with System, 7.1, i think. Macs always had low battery warning, set by the user, the options were in the battery menu bar, i usually had mine at 20% with repeats after that every 5%. you could make it do whatever you wanted. It stopped being available when i got a new MBP with Mountain Lion. If anyone could tell me what i'm not seeing that could give me a warning, i would be grateful. Before Mountain Lion, there was a little window that came up in the middle of the display which said something like Warning: your battery has 20% of capacity left, something like that. i just took it for granted. Of course it had that. What decent operating system wouldn't have that?

i have Catalina, i got it when i got a new MBP in October 2020, July 2020 build, it came with Catalina 10.15.7 i think.
