more questions about the MacBook Pro, Core i5, 2.8 GHz (I5-4308U), model A1502 (EMC 2875), a model where I cannot disconnect the battery, because the whole case is closed, a model Im going to use to experiment with mac and create a partition to install a linux distro alongside the mac os.

My favorite notebook is a one that lets me take the battery off if I don’t need it. This way I’ve been able to need just one battery in the last 8 years. Regarding the mac, I’m going to need a new battery (it lasts 5 hours the most) and don’t want to waste charging cycles.

My question is twofold:

  • Is there any linux program that lets me manage the battery so I can choose to rely solely on outlet power, even if I cannot physically remove the battery?

  • the same question for mac.

    Some laptops allow for controlling level kf charge. For example I keep my battery at 65% to prolong its life. If its supported, you should be able to set it through /sys/class/power_supply/bat0/charge_level

    i dont rember file name and path exactly but shouldnlook like this

    Edit: Correct filename is /sys/class/power_supply/BAT0/charge_control_end_threshold

      I do the same. My laptop had a weird bug where it would reset that value to 100 every reboot, so I made a systemd service to write it at every boot.
