macbook air os update ruined battery life

For those that prefer a milder MacBook experience, a good rule of thumb is to replace the battery when its run-time is down to 25 percent of the brand new run-time.

How low you want to run your battery is a really personal preference-and some users like to keep things spicy.

Are you now only able to while away a few minutes before your MacBook demands to be charged? Sounds like it could be time for a new battery. Remember when you first unplugged your new MacBook? Who could forget that sweet feeling of freedom as you whiled away the hours, anywhere you pleased. If the number of charge cycles used is close to the maximum number of charge cycles for your model, you should start thinking about replacing the battery. Compare that to the maximum cycle count for your model, listed on Apple’s instruction page. Check out Apple’s instructions here. The Power section of your Mac’s System Information menu lists how many charge cycles your battery has been through. With a little digging, you can find some more details about your battery’s health.
