Apple is famous for enhancing the battery life of its products. And the MacBook is no different. The lithium-ion batteries from the company have a microprocessor that serves to estimate the level of charge and also the useful life of your material. If they are left unused for a long time, or if they receive an irregular charge and discharge cycles every day, it is very important to calibrate them. If you do this you will not end up with a battery that shows 30% charged, but one minute later it turns off without feeling sorry for your work.
Why is it Important to Calibrate the Battery?
An annoying thing is that Apple does not make clear in the manuals and packaging of its products the importance of this calibration. It goes so far as to indicate on obscure pages of its website that it is important to calibrate the battery as soon as you buy the device to optimize the use of its battery life. Apple Inc. even offers an area on its website dedicated to batteries and another explaining how to do the calibration, but how about we simplify things further by centralizing the most important issues here?
Your Battery in Numbers
Before you go any further, download and install the free software. There are many tools to explore the battery data, they are usually very small and will tell you how it is doing without rolling. In addition, you have access to general information about your system.
If you see that the number of cycles already has several digits and your battery has been lying blatantly about the charging time, it is more complicated. After calibration, the Health of the battery can be returned to 100%.
How to Calibrate?
Plug the MacBook into a wall outlet, fully charge the battery, and leave it at 100% charge for two hours. You can continue using your computer as normal.
Unplug your MacBook and put the battery to work until it is completely discharged. If you want to speed up the battery drainage process, turn on Wi-Fi and Bluetooth, increase the brightness of the screen, play a game or watch a movie, connect an external monitor, or everything at the same time until the machine shuts down due to lack of load.
Now you will have to shut down your MacBook during this time. And let it rest for at least 5 hours. Now, plug the notebook back into the outlet for a full battery charge, until it reaches 100%.
It is. It is now calibrated and can indicate better health in software that you installed and now you will get a much safer estimate of how long you still hold your machine.
Don’t Be Fooled by Charge Cycles
Apple reports that its internal batteries are capable of lasting up to 1000 complete charge and discharge cycles, while removable ones can last for some 300 cycles. It is the irregular charging cycles that can cause problems in the health of your battery in the long run. Leaving the microprocessor confused. The same happens if you always leave your MacBook plugged in, a common thing for those who use the notebook as a Desktop.
Do not think that there is a right or wrong way to use the battery. Use your MacBook as you need it, as lithium batteries are designed to survive unexpected charges and discharges. Also, you should not discharge and fully charged the MacBook’s battery daily, unless you really need it.
What Is the Indicated Interval to Calibrate?
It depends. If the MacBook is plugged in for a long time, it is advisable to perform one calibration per month. If you use a lot out of the socket, do the process every two months.
If you are going to store the machine for a long time, leave the battery charge at 50%. Despite all the built-in technology, fully discharged batteries can suffer “memory effect” wear and lose load capacity. Storing them for long periods at full load is also not a good idea.
This way you can have a good battery life of your MacBook and you can have this battery health for a time. Because of keeping your battery in good condition, you must calibrate the battery once a month.
