Battery Capacity is low!

How can I restore the battery capacity without having to bring my MacBook in for service?


MacBook Air 13″, macOS 11.6

Battery capacity cannot be restored. As a consumable item, Apple recommends you have it replace when it gets to 80% capacity. You can, of course, run it lower than 80% if you choose, but for best overall performance, 80% is a good break point.


Most non Apple batteries, even those sold by top line vendors, are not nearly as good as the ones Apple supplies. You'll be money ahead having Apple replace the battery.
