Rapid loose of battery power under 30% of loading level

@hirsch75736 - Can't say, as I have nothing to work from which is why I skied for the screen shot.

I somehow answered the wrong issue here, sorry for that. I cannot attach the screenshot here?

@hirsch75736 - This appears to be the same system with your other question. I’ve answered it there. To offer a bit more context the Intel chip used in this series when full out exceeds the power draw from the charger and starts using what the battery has to fill the power gap. The length of time the of this heavy power draw will exhaust the banked power and the system will shut down if the systems thermals were not an issue by placing the system into a freezer! Many young video production studios did this to render their work as there just not even an option with a Mac desktop system. And even Apples release of a new MacPro system was just too much for many.

Basically the Use needs outstripped what hardware folks where making and the needed tech was not available. Both Intel and Apple gambled and since Intel over promised what they could deliver ended up with most of the mess on them. Apple like-wise got stung as they believed in what Intel was promising and caught up in the Thermals of this chip series.

Thanks for this @danj. So the quick loading drop is just a bad communication between sensors and system, did I get that right?

So the basic question behind all this is: Do I have to return the battery and ask for a replacement, or is this not getting better, even with a new ifixit battery?

Let's give this a try, within Activity monitor you can track the batterywith what Apple offers.

Here's how you can use Activity Monitor to track your battery:

Time on Battery:

- The "Time on Battery (unplugged)" and "Time remaining (unplugged)" metrics provide information about how long your Mac has been running on battery and how much time is estimated to remain.

Battery Charge Level:

- The "Battery (Last 12 hours)" graph shows the battery charge level over the previous 12 hours.

Energy Impact:

- The "Energy Impact" measure helps you identify which applications are using the most energy, allowing you to potentially reduce battery drain by closing resource-intensive apps.

12hr Power:

- The "12hr Power" column in the Energy pane indicates the average energy impact of each application over the last 12 hours.

To view this information:

- Open Activity Monitor App

- Click on the "Energy" tab at the top. 

- Look for the information related to battery usage, including "Time on Battery (unplugged)", "Time remaining (unplugged)", and the "Battery (Last 12 hours)" graph. 

- Look at the "Energy Impact" and "12hr Power" columns to identify apps that are consuming significant energy.

@danj thanks for your enduring help!

So the first two metrics did look misleading to me and at least I could grab the battery drainage, now!

This looks like a broken battery, doesn't it?

Especially the "Time remaining" was absolutely not possible at 50% charching level. Considering this range with a normal behavior would result in this estimate. But as this percentage range shows a different behavior it is no realistic guess. Here are the images:

These images were taken at 8 a'clock

And one hour later it is this:

So it really seems broken ...

@hirsch75736 - This is only part the story! What was the system doing and the temp. All three need to be collected within the same window of time.

Did you get TG Pro installed?

@danj It was at sleep for 10 hours. Than I was just opening the case and reading some news sites in the browser. There was nothing in the background. It resulted in 43% of power consumption for browser. 24% for Mail, the rest for usual system apps. There was no heat.

I'm sure it somehow deals with the periods in sleep mode. It seems like the systems thinks, there is no power usage of the battery, but actually there is.

When I use the battery in one period, say 4 hours, no problem with the battery. But when I use it for some days with long periods of deep sleep in between, it will always result in a power drop when the battery shows a wrong higher level and has actually only 10 percent left, because there was power drain during sleep which is not recognized by the system.

I use Mac Fan Control instead of TG Pro.
