It turned out the fault was with the MagSafe charger which wasn’t functioning. We once took a MacBook Air to an Apple Store because it wasn’t charging. Thus, you will consume charge cycles even if your MacBook is mostly plugged in, with only the occasional hour or two on battery power. Using 50% of the battery life one day before recharging and using 50% the next day will mean one charge cycle has been notched-up.

It should be noted that a charge cycle doesn’t necessarily mean entirely running out of juice from a full charge.
This is important because during each charge cycle the battery loses a small fraction of its ability to hold charge, which is what causes the capacity to drop over time.
This measures how many times 100% of the battery charge has been used-up. What is a good battery cycle count for MacBook?Īnother figure worth noting within CoconutBattery is the Cycles Count figure, which is also known as the charge cycles figure. It just won’t last as long as it once did, and a Replace Soon status message will almost certainly appear. However, the MacBook will still report the battery is charged 100%.

A MacBook Pro that had an original design capacity of 5,400mAh and now stores only 3,700mAh has lost just over 30% of its capacity, for example. Apple doesn’t explain how it generates the battery life status reading but it’s probably divined by measuring the maximum charge the battery can currently hold against its original capacity when new.ĬoconutBattery will display both these figures, measured in milliamp hours (mAh).

Perhaps surprisingly, Replace Soon is a mere warning rather than a demand and your MacBook should still function correctly on battery power, albeit with noticeably shorter battery life than when it was new.Īpps like the free CoconutBattery (above) let you dig-down into technical details to get more detailed information. It should be obvious that Normal indicates a healthy battery.
