no "LOW BATTERY" warning - Sonoma

Feel free to let Apple know what you feel would be the optimal time for the warning.

Feedback - macOS - Apple

Apart from what has already been posted

There is a free or paid for application called CoconutBattery

You will have to search for it

If configured in CoconutBattery >> Setting >> Notifications

It can be set to Alert when battery gets below xx %

The thing is, the application Must be running all the time

That too can be configured to do exactly that, run all the time.

The operating system will send a low battery dialog when the remaining battery capacity drops to around 2%. Not too much reaction time after that to take action and connect to a power source.

Technically the 2 % warning should occur.

That is unless the battery capacity has degraded to such a level that it just does not have time to offer the warning.

Should one use the suggested CoconutBattery application

It does read from the same Internal Sensor that are included in macOS 14 and related to battery heath

It may provide some insight as to the Difference between to actual heath and the Designed Heath of the battery

From there website as example

I've had no such warning

Apple has had that 2% setting for years as inane as it may seem.

I am running Sonoma 14.4.1 on a M2 Mac mini. There is no Batteries entry in Notifications on my MacBook Pro running Ventura 13.6.6 and no means to add it there that I can see from the Battery preference.

The operating system will slide in a 2% warning notification should you let it go that long.

Welcome

Best we do not embroiled in the who and why and how many others - is it not.

We are not here to bash but to try and offer possible Options that are available.

Personally, I keep the Battery appearing in the Menu Bar with % ages enable.

Takes less than 1 minute to look up and see the Red Battery icon ( help be here @VikingOSX if that is correct )

Red icon would be the Visual 2 Minute warning

As I mentioned earlier: I do not receive any warning. Laptop just turns off when battery is gone.

no warming. No red symbol of the battery. No pop-up window at 2 %

I'll have to check a Sonoma system, but I know with Big Sur & Ventura I get the macOS notification when the battery charge drops to 10% and that notice stays in place until I actually acknowledge it. I wonder if you have some third party software installed which may be interfering.

Plus, I wondering if your battery has developed a hardware fault that just is not registering in macOS or with the Apple Diagnostics. Coconut Battery which @PRP_53 suggested has a history of the battery's Full Charge Capacity (FCC) which may provide a hint of a failure, plus the app may have a different interpretation of battery health from monitoring the FCC over time. I have used the command line to monitor the FCC values while performing a stress test on the battery which tends to reveal weaknesses in the battery that don't usually show up in the Apple Diagnostics or macOS battery condition assessment. When the FCC value drops significantly when using the laptop under heavy load, the battery charge level can easily drop 5% which can be enough to bypass any macOS hibernation options to cleanly save the system. I haven't used Coconut Battery enough to know how it behaves, but it does have a free version which gives you basic details for you to check out.

FYI, when the battery charge is under 10% (the closer to 1% the better), you will more likely see the battery condition in macOS to change to "Service Recommended" (depends on how often macOS polls the battery for health information), or the diagnostic is more likely to fail (connecting the charger can sometimes cause the condition to disappear, but the charger is necessary for the diagnostics).
