Adam Kos When you use your Mac laptop, its battery goes through charging cycles. At the same time, one charging cycle means a complete discharge of the battery - but this does not necessarily correspond to one charge. For example, you can use only half of the power in one day and then charge the battery to full again. If you do the same thing the next day, it will count as one charge cycle, not two.
Batteries have a limited number of charge cycles, after which a reduction in performance can be expected. In this way, it can take several days to complete the entire charging cycle, thus extending its life. After reaching the given number of cycles, it is recommended to replace the battery in order to maintain the performance of the computer. You can still use the battery after reaching the maximum number of cycles, but you may experience a shorter battery life.

You can tell when the battery needs to be replaced by the number of used and remaining battery charge cycles. Your battery is designed to retain up to 80% of its original charge capacity after a maximum number of cycles. However, you will of course get the best performance if you replace the battery after reaching the maximum number of cycles.

A very small number of customers who have a 2016 or 2017 MacBook Pro have encountered an issue with the battery not charging above 1%.

If your 2016 or 2017 MacBook Pro is experiencing these issues, update to macOS Big Sur 11.2.1 or later. This operating system should solve the problem. If not, you must directly contact Apple and have the battery replaced for free. Before service begins, your computer will be checked to see if it qualifies for a free battery replacement. You can do this yourself by checking the condition of the battery.
