Everywhere we look we are surrounded by all these technology and gadgets, and all these gadgets are powered by Batteries! And these incredible things run out of juice and you recharge them to keep your life going. But little do you know every battery has a limited battery life, and here’s how you can check the battery life on your MacBook.
The technical term for the life of battery is know as “Battery Cycle”. After a limit number of cycles your battery will lose it’s capacity to hold power and you’ll realize you can’t run your MacBook as long as you could before.
Apple knows that batteries don’t always last as long as the computers that they reside in, so it has made it easy to check how many charge cycles a battery has had by simply clicking a few buttons.
In Apple’s words
A charge cycle means using all of the battery’s power, but that doesn’t necessarily mean a single charge. For instance, you could use your notebook for an hour or more one day, using half its charge, and then recharge it fully. If you did the same thing the next day, it would count as one charge cycle, not two, so it may take several days to complete a cycle.
- Click the Apple logo on the top-left of your Mac’s screen and choose “About This Mac.”
- Next, click on “System Report.”
- Now, click “Power” on the left hand side and look for the entry in the right-hand pane that mentions charge cycles. The number beside it is how many your Mac’s battery has gone through.
Now a large number here is not unusual, and Apple has a list of how many charge cycles should be expected before a battery is ready for replacement, as shown in the chart below. If yours is getting close to, or has exceeded the recommended number of cycles then it may be time to invest in a new battery
