The term calibrate is a just a fancy way of saying that you should reset your battery’s memory. This will show you how to calibrate the battery on your Apple Laptop in 4 simple steps.
Why Calibrate Your Macbook Battery
Your battery is actually pretty smart. It has an internal microprocessor built in that controls the time remaining box you see in your toolbar and also manages the battery’s energy efficiency. Recalibrating your battery makes sure that this little computer’s numbers stay on track and you get better battery life from your Macbook.
How To Calibrate Your Macbook Battery
- Charge Fully
- Run It Down All The Way (You can use it while you do this)
- Let is sit for 5 hours (while the battery is flat)
- Charge it Fully again – You’ll know it’s full when the charger light turns from amber to green
That’s it, you’re done.
Apple recommends that you do a calibration once per month to get the best possible battery life from your Macbook. I have an alarm set on mine that reminds me once a month.
