MacBook Battery Calibration – Need, Methods and Life Cycle

Jan 14, 2021   Pageview:35

Are you using a MacBook, and you are wondering if it is possible to calibrate the battery? Most laptop batteries require calibration to help keep the battery in check and know the battery conditions. You might be using a dying battery, but you fail to notice due to the wrong information given.

The system's battery readings are often crucial in giving you the direction that your battery is taking. It is usually recommended that you calibrate your battery twice a month to get the correct readings.

I can remember the last time I had an HP Laptop, but I knew nothing about battery calibration. The battery readings show that the battery could last for about three hours, but it only lasts half the time.

The computer could go off when the battery readings were 20%; thus, I had to consult an expert. He asked me if I had calibrated the battery in the last three months, and I was like, 'what are you saying!' He taught me everything, and I could not leave the battery in the same condition again.

Therefore, this writing will tell you if it is possible to calibrate a MacBook battery and how to do it. Follow me through, and I am sure you will benefit a lot from this session.

Do you need to calibrate your MacBook Pro Battery?

The power management system of a laptop battery plays a vital role in the entire battery's lifespan. Therefore, it is essential to calibrate the power management system after installing the new battery twice each month.

The battery should be calibrated after replacing a battery because it allows the battery to

  • Achieve its fullest charge capacity

  • It allows the new battery to reach its full lifespan.

  • It makes the system to display the battery level accurately.

All MacBook, MacBook Pro, and MacBook Air use a battery with an internal processor to maximize battery performance. The battery and its processor must undergo a calibration routine to make accurate predictions about the remaining battery charge.

Correctly calibrating and maintaining your MacBook battery improves its performance and put off replacing it for the longest time possible. However, as the MacBook ages, the battery performance decreases, which is always the case with batteries.

A correctly calibrated battery helps you keep the tabs on your power source and prevent the disappointment of having your MacBook not giving you a warning before it goes off. Therefore, it is more of getting accurate information than it is maintaining the battery.

The process of calibrating the processor is so simple. The steps are quite understandable, and you do not need any expert help to run them. I will give you a detailed procedure on how to do it. You can thank me later for saving your MacBook from future troubles. The next topic will cover the entire process with the things you should do and what you should never do.

How do you calibrate your MacBook Pro Battery?

The process of battery calibration has several well-organized steps. With these steps and procedures, you will never go wrong. Therefore, use the steps below to calibrate your power management system.

Plug your MacBook in.

Plugin your MacBook charger and ensure that it is charging. The charger and the computer usually have a light that indicates the battery is charging.

Let the battery attain full charge.

it is essential to ensure that the battery is fully charged and the computer is displaying 100%. When it is fully charged, the light on the power adapter changes from orange (charging) to green (fully charged). To get this, you can flip the laptop over and press the button on the battery. All the lights will turn green if the battery is fully charged.

Ensure the battery is fully charged for two hours.

You should keep the adapter plugged in for the entire period and ensure the adapter light remains green. Do your work normally on the computer but do not switch off the computer at any given time.

Disconnect the power adapter.

After the two hours have elapsed, you can disconnect the adapter from the MacBook. The process will have given the power management system time to analyze the battery.

Discharge the battery completely.

Keep the computer on and use it usually and once the warnings about low battery life appear, save your work. When the battery reaches a low level, it will go to sleep automatically.

Leave the computer for 5 hours.

Do not recharge the battery immediately. Give it at least 5 hours to discharge the final remnants of the battery. It also resets the processor to detect absolute zero power.

Recharge the MacBook.

After completing 5 hours, recharge your battery because it has already being re-calibrated. The MacBook will start to display accurate battery status all the time.

The process requires a lot of time, but it is good for your battery. Performing this process at least every month will always tell when the battery is ending its lifespan. It is good to understand this so that you can get prepared to replace it immediately.

How many cycles is a Mac battery good for?

The current Macs that is, MacBook, MacBook Airs, and MacBook Pros) use batteries that have been assessed to have 1000 battery cycles. This implies that such batteries are good enough to last for at least three years of regular use.

The older types of Macs had batteries with 300 battery cycles meaning that they lasted for fewer years. The manufacturers use the battery cycles to estimate battery life. Knowing about the number of life cycles that your battery has and the number of cycles left will help you decide when to replace it.

To get more information about the MacBook Pro battery and battery cycles, follow these steps:

?Hold the option key, then click the Apple Menu. Choose the System information option.

Under the hardware part of the System Information window, select Power. You will see the current cycle count listed under the Battery Information section.
