As you can probably tell on my last few posts, I have really been on this battery theme. Well, this post will be the last one for a bit on battery life. This post is not so much about saving battery life as it is about giving you an accurate reading of your battery life? So why is this so important? Well, the main reason why you want to calibrate your battery is you want to make sure that your battery indicator is in sync with your actual battery in your Macbook to make sure you have optimal battery performance. Here are the steps that you need to take to make this happen.
- You will want to plug in your MagSafe battery adapter into your Macbook. Charge your Macbook until the green light on the adapter comes up and that your battery indicator on your Macbook shows that it is charged.
- Keep your Macbook plugged in and in this fully charged state for at least two hours or more. You can use your Macbook during this time.
- Disconnect the power adapter from your computer and use your computer as you normally would
- When your battery gets down to about 20% you will see a warning on your screen indicating that this happened. Continue to use your computer and save any work that you need to.
- Keep your computer on and let the battery drain. When the battery is drained, the computer will automatically go to sleep mode.
- At this point, turn off the computer and let it stay in this mode for at least 5 hours. What I like to do is that if I can plan this right, I would do this step over night while I am sleeping.
- The last thing you are going to want to do is then turn on the computer with it plugged into the adapter and have it fully charge. You may use the computer during this time.
Your batter should now be calibrated. You should now have a good indication of an accurate battery in your menubar. If you are a heavy user of your macbook, this is something good to do every month. If you are more infrequent user, then every other month or so is good. I hope this helps you out a bit in your battery saving.
