You’re using a MacBook and wondering if it’s possible to calibrate the battery? Most laptop batteries require calibration to help check the battery and understand its condition. You might be using a dying battery, but you didn’t notice it because of the wrong information provided. Your system’s battery reading is often critical to giving you battery usage directions. It is generally recommended that you calibrate the battery twice a month for proper readings.
This article will tell you if and how to calibrate your MacBook battery. Let’s take a look below!
Do you need to calibrate your MacBook Pro battery? The power management system of a notebook battery plays a vital role in the entire battery life. Therefore, after installing a new battery twice a month, the power management system must be calibrated.
Batteries should be calibrated after battery replacement, as it allows the battery to reach its maximum charge capacity, allows the new battery to reach its full useful life, and allows the system to accurately display the battery level. All MacBooks, MacBook Pros, and MacBook Airs use batteries with built-in processors to maximize battery performance. The battery and its processor must go through a calibration procedure to accurately predict the remaining battery charge.
Properly calibrating and maintaining your MacBook battery can improve its performance and delay battery replacement as long as possible. Therefore, obtaining accurate information is more important than maintaining the battery.
How do I calibrate my MacBook Pro battery? The battery calibration process has several well-organized steps. Therefore, use the following steps to calibrate your power management system:
1. Plug in your MacBook.
Plug in your MacBook charger and make sure it’s charging. Chargers and computers usually have an indicator light to indicate that the battery is charging.
2. Fully charge the battery.
You must make sure the battery is fully charged and the computer shows 100%. When fully charged, the light on the power adapter will change from orange (charging) to green (fully charged). To do this, you can flip the laptop over and press a button on the battery. If the battery is fully charged, all lights will turn green.
3. Make sure the battery is fully charged for two hours.
You should keep the adapter plugged in the entire time and make sure the adapter light stays green. Works fine on the computer, but don’t shut down the computer at any given time.
4. Disconnect the power adapter.
After two hours have passed, you can disconnect the adapter from your MacBook. This process will give the power management system time to analyze the battery.
5. Fully discharge the battery.
Keep your computer powered on and in normal use, and once the low battery life warning appears, save your work. When the battery is low, it will automatically go to sleep.
6. Leave the computer for 5 hours.
Do not charge the battery immediately. Give it at least 5 hours to release the last remnants of the battery. It also resets the processor to detect absolute zero power.
7. Charge your MacBook.
Charge the battery after 5 hours as it has been recalibrated. Your MacBook will start showing accurate battery status at all times.
This process takes a lot of time, but it’s good for your battery.
How many times can a Mac battery be cycled? Current Macs (i.e. MacBooks, MacBook Airs, and MacBook Pros) use batteries that have been rated for 1000 battery cycles. That means this battery is good enough for at least three years of normal use.
Older types of Macs have batteries with 300 battery cycles, which means they have a shorter lifespan. Manufacturers use battery cycles to estimate battery life. Knowing your battery’s life cycle and remaining cycles will help you decide when to replace the battery.
To get more information about your MacBook Pro battery and battery cycles, follow these steps:
Press and hold the Option key, then click the Apple menu. Select the System Information option. Under the Hardware section of the System Information window, select Power. You will see the current cycle count listed under the Battery Information section.
