I watched a clip yesterday that talked about recycling power on Mac laptop to increase the lifespan of the battery.

I used coconutbattery to check the capacity of the battery and it says 86%. After following the instruction - Charged the battery to 100%>>Unplugged the power source and run the battery down>>Allowed the battery for over 5 hours>>And then started my laptop again.

When I used the coconutbattery again, the capacity of the battery dropped to 74%.

So what is the problem?
 
The problem is that the 86% estimate was wrong. You showed the computer what was right by draining the battery completely, so now it knows that the battery can hold 74% of its original intended capacity.

This is normal. As batteries age, they don't hold as much. Every once-in-a-while, it's good to drain the battery completely, if only because it lets the computer know better what the current life of the battery is.


The whole thing about "increasing the lifespan" is BS.
