Sometimes we take our macbooks for a "walk" and while we are, work or have a little fun with him, but nevertheless as the time of use goes by and the times we use it, we are noticing how the performance of the battery is not the same as before, generally going worse.
So all we have left is perform routine battery maintenance that Apple proposes us, that is to say, tips as simple as not leaving the power adapter connected to the macbook all day, trying to unplug it from time to time so that the electrons of the lithium-ion battery flow and thus lose the minimum possible capacity. Another advice they give us is that if you are not going to use it for a long period of time, leave the battery only 50% charged, which is very useful so that it does not wear out even without using it.
