I would like to get the number of recharge cycles using bash (terminal commands). I understand the following command will display all of the battery data, but I want the cycle count on its own

ioreg -l -w0 |grep Capacity

I use the following command to get the battery percentage, so I imagine it can be modified slightly to get the cycle count instead;

ioreg -l | awk '$3~/Capacity/{c[$3]=$5}END{OFMT="%.3f";max=c["\"MaxCapacity\""];print(max>0?100*c["\"CurrentCapacity\""]/max:"?")}'

I'm new to bash, so I'm not completely sure how that code works, or how I'd adapt it for my needs.

Any help would be appreciated. Thanks.

Something like

system_profiler SPPowerDataType | grep "Cycle Count" | awk '{print $3}'

should do the job.

system_profiler SPPowerDataType | grep "Condition" | awk '{print $2}'

will get you the battery condition, for example: Normal.

If you want more output, run:

system_profiler SPPowerDataType | grep -A3 -B7 "Condition"

to get something similar to this:

      Charge Information:
          Charge Remaining (mAh): 2405
          Fully Charged: No
          Charging: No
          Full Charge Capacity (mAh): 3816
      Health Information:
          Cycle Count: 187
          Condition: Normal
      Battery Installed: Yes
      Amperage (mA): -2635
      Voltage (mV): 11212

    How about battery condition? – BenSmith Feb 02 '17 at 22:16

    @BenSmith system_profiler SPPowerDataType | grep "Condition" | awk '{print $2}' will get you the battery condition – joni Apr 08 '18 at 05:29
  • Unfortunately system_profiler is not available in the safe boot environment. – Berik May 02 '21 at 17:13

    If you're having problems doing this from Terminal in recovery mode, just run chroot /Volumes/Macintosh\ HD zsh first, then run the above commands – bdev Oct 16 '22 at 18:56

system_profiler SPPowerDataType | grep -A3 -B7 "Power"

I just do this, and it will do the things.
