1. Basic things to know about MacBook batteries
To use MacBook effectively and ensure the longevity of the device, understanding the battery is an extremely important factor. Because if not properly cared for, MacBook batteries can quickly deteriorate, reducing performance and affecting the user experience. Below is detailed information about MacBook batteries that you need to know to better protect your device.
1.1. Types of batteries used on MacBook
MacBook uses Lithium-ion batteries , the most modern and advanced battery technology today. The outstanding features of this type of battery are:
Fast charging time: Lithium-ion batteries can be fully charged in a short time without affecting the performance of the device too much. This helps you save time and use the device immediately when needed.
Large capacity: This battery is designed with large capacity, ensuring long-term use, meeting the needs of continuous work for a long day without having to recharge many times.
Long Life: With the use of advanced technology, Lithium-ion batteries can maintain good performance for a long time, helping to prolong the battery life. MacBook can use the battery for about 1000 charge cycles before it drops to 80% of its original capacity. This is an impressive number that helps MacBook operate stably for many years.
1.2. MacBook battery charging cycle
A charge cycle is when you use up 100% of your battery's capacity, but it's not necessary to fully charge the battery in one charge.
For example, if you charge from 50% to 100% today and then the next day you charge from 50% to 100% again, both times will count as one complete charge cycle.
The number of charge cycles that a MacBook battery goes through directly affects its lifespan. After about 1000 charge cycles, the battery capacity will decrease to about 80% of its original capacity. However, this reduction is still enough to meet basic usage needs such as working, browsing the web, watching movies, etc.
This means that using your MacBook properly and avoiding overcharging can help you save more charge cycles and extend the life of your battery.
1.3. Smart charging technology on macOS
MacBooks now feature Optimized Battery Charging technology, which minimizes frequent charging and protects the battery from rapid deterioration.
When this feature is enabled, macOS automatically adjusts the battery’s charge level. Instead of charging to 100%, your MacBook will stop charging at around 80% and only resume charging to 100% when you need to use it for an extended period of time, such as before you leave for work. This feature helps reduce the stress on the battery from constantly charging, protecting it from rapid deterioration. This is especially important if you frequently leave your laptop plugged in for long periods of time.
To enable Optimized Battery Charging, you can go to System Settings > Battery > Battery Health and select "Optimized Battery Charging."
1.4. Some technical parameters you need to know
For a more comprehensive look at MacBook batteries, here are some specs you should know:
Battery Capacity: The capacity of a MacBook battery is usually measured in Wh (Watt-hour). Different MacBook lines, such as the MacBook Air and MacBook Pro, have different battery capacities, depending on the size and design of each machine. Typically, the MacBook Air has a lower battery capacity than the MacBook Pro, so the usage time is also different.
Battery life: The battery life of a MacBook depends on how much you use it and the model you own. On a full charge, a MacBook can last between 8 and 12 hours depending on the tasks you perform, such as browsing the web, doing office work, or watching videos.
Charging time: It takes about 1.5 - 2.5 hours to fully charge the MacBook battery, depending on the remaining charge level and the type of adapter you use. If you use a high-power adapter, the charging process will be faster.
2. Tips to Use MacBook Without Battery Damage
2.1. Charge the battery for a newly purchased Macbook
Not charging the battery is one of the ways to use and preserve the battery for genuine Macbook, new, modern models that many people recommend. Instead, use it normally until the device reports that the battery is about to run out. At this time, charge it for 10 hours to have a good battery life. Note that the next time you only need to charge for about 5-6 hours.
2.2. Do not let the battery run out before charging.
It is no coincidence that Apple sets the low battery level at 20%, this is the battery level that "reminds" you to charge the battery immediately. Therefore, you should not let the battery run out before charging, it will affect the battery quality. You can remove the battery when it reaches 80% and continue to use it until it is almost empty and then charge it again.
2.3. Can be charged anytime
How to use MacBook without battery failure – Many people ask whether they should continue charging when the Macbook battery is full. In fact, you can rest assured because Apple’s operating system – MacOS will automatically switch to direct power when the battery is full, cutting off the power to the battery to ensure battery safety.
2.4. If possible, you should plug in your Macbook battery regularly.
If you use Macbook regularly, you should plug in the charger directly, this is a way to use Macbook battery to increase battery life. Only use the battery if moving. This helps the battery have a good life, limiting battery failure because when the battery is full, Macbook will automatically switch to external power mode, helping to reduce battery cycles.
2.5. Do not let the device get too hot when in use.
When using a Macbook, you should minimize the amount of heat that the device gets. Try to let the device cool down when charging the battery. If the device is hot, do not rush to plug in the charger as it can affect the battery life. You can use a cooling pad to help the computer cool down quickly to increase the product's life. This is also a way to use a Macbook without battery failure that many technology experts share.
2.6. Reduce screen brightness and keyboard light when not needed
To use Macbook battery for a long time and ensure safety, you should reduce screen brightness and turn off keyboard light if not needed. This helps you save Macbook battery effectively.
2.7. Should use genuine charging cable
Using the right charging cable is very important for users. Remember that a good charger will help ensure your battery life is always working well. Limit the use of chargers of unknown origin. When charging, ensure a stable voltage source, especially the battery input voltage. If the voltage is not enough, the battery will take a long time to fully charge and even affect the quality of the charger and Macbook battery.
