Battery health poll

[citivolus]

I'm interested in sampling actual data as my battery health has been declining with limited use and not plugged in all the time.

If possible use an app like CoconutBattery which reports raw health instead of Apple's built-in Battery info.

Please post the following info with your responses:

M1 MBA: 56c, 96%

M1 Mac mini

110%

 

[Mike Boreham]

M1 MBA: 30 cycles, 96.2% from ioreg, (using the @jdb8167 script battery.sh from here.)

The health reported by Apple in System Information and Battery Pref pane is still 100%

Note that health is constantly changing. My M1 MBA was new in November 2020 but I only started monitoring it, with Better Battery 2, in late Feb. Since then it has varied from 98.1%, down to 94%, recovered to 97%, currently at 96.2%. I believe this is why Apple only give us a heavily damped number, to stop loads of premature complaints and claims.

It has been plugged in nearly 24/7 with Apple Battery Optimising on but I only saw it reduce charge from 100% once briefly, before I switched to Al Dente in mid Feb.

This poll is useless without knowing the age and battery cycle count...

For those of you concerned about battery health, there is no better app than this:

AlDente

AlDente – Charge Limiter The ALL-IN-ONE charge Limiter App for MacBooks. Download Free Get AlDente Pro AlDente gives you the tools you need to extend the life of your MacBook battery. Why do I need this? Li-ion batteries (like the one in your MacBook) last the longest when operated between 20%...

apphousekitchen.com

There is a free version, but the paid version is well worth the money.

Because I had a little trouble finding it based on previous link; the battery.sh script is here:

https://raw.githubusercontent.com/jamesdbailey/m1batterystats/master/battery.sh

You should open a text editor, paste in that code, and save it as "battery.sh"

Then you can run it in terminal like this:

% sh battery.sh
Current charge 3010 mAh
Full charge capacity 4210 mAh
Charge at 71.400% capacity
Design capacity 4382 mAh
Current full charge at 96.000% design capacity
Cycle count is 49
Battery temperature 88.610 °F
Power adapter at 55 Watts
battery.sh: line 38: bitwise: command not found
battery.sh: line 40: [: -ge: unary operator expected

You can install the bitwise command line tool to get rid of the errors.

bitwise-arm64
bitwise-x86_64

This is a slightly modified version from here: https://github.com/mellowcandle/bitwise. I modified it to return values from pipes on the command line based on an output parameter.
