I use my laptop mainly running off of AC power. I would like to keep my battery as healthy as possible, even if it is just a little bit, because neither of the below options hurt me in any way.

Apple recently released a software update with a "battery health management feature" which seemingly cycles 90-100% on the MacBook battery every day.

There is software for the MacBook as well, such as Al Dente and Charge Limiter which allows you to limit the charging of your battery. At your specified charge level, the laptop will stop charging and run off of AC power.

Given these two options, which one should I go for? Which one would be better for my battery's longevity? Assuming I'm find with both options, of course.

  • Can you add a screenshot of what you see in System Information > Hardware > Power? – Todd Jun 9 '20 at 1:00

    I would recommend letting it stay at 50% because that is probably the best way to keep your charge cycles low. If I remember correctly, the fewer charge cycles, the better. – Todd Jun 9 '20 at 1:09
  • Batteries are just a container of chemicals which inexorably deteriorate upon first use. I make sure my laptop is fully charged before turning it off for the night. Then I use it on battery until down to about 25% and then charge it again. A good battery lasts about 3 years give or take. – John Jun 9 '20 at 1:12
  • @Todd I would tend to agree, but I'm also wondering if there any any nuances I'm missing. In any case though having a low cycle count does increase resale value, so I guess I'm more interested in that – Skeleton Bow Jun 9 '20 at 1:13
