In recent years, everyone seems to have some consensus on extending battery life: such as avoiding overheating, avoiding overcharging and overdischarging, and charging to XNUMX%.
Apple has also applied these concepts to the new iOS system to charge the iPhone. For example, if you plug the phone into the charger before going to bed, it will not charge the battery directly, but will stop when it is about 80% charged. Recharge the battery when you wake up.
But Apple's laptops are still plugged in to fully charge, and if you use your MacBook Pro/Air plugged in for a long time, it may adversely affect the battery.
Lithium-ion batteries, like those in a MacBook, have the longest lifespan when they're running between 20% and 80%.Keeping the battery at 100% at all times can significantly shorten the lifespan of your MacBook.
So how do we make our MacBook run within the appropriate power range?You might consider using:AlDente.
AlDenteThere are only two simple functions:
Charge Limiter: Allows setting the maximum charge percentage between 20% and 100%.It can be set using the slider bar or by entering the desired percentage in the field above and hit enter.
Discharge: This feature lets your MacBook run entirely on battery, even when it's plugged in.So you can actively discharge your MacBook to a healthier percentage.However, when activating the discharge, due to technical limitations, clamshell mode is not supported.
The official website gives a detailed installation guide, and the operation is also very simple. The main steps are as follows:
- Download the latest AlDente
- Open the downloaded .dmg file
- In the window that pops up, drag and drop the AlDente logo into the Applications folder
- Go to the Applications folder in Finder and double-click AlDente.
- If the following warning appears, click Open.
- AlDente will now open automatically, all you have to do is follow the instructions.
How To Use
Once installed, enter the desired maximum value.Click the AlDente icon on the menu bar to view the charge percentage.Usually it takes a minute or two for the OS to register the changes, so be patient.You can check if it works by setting the maximum value.Percentage, for example: 80%.After a while, if the remaining charge exceeds ≈73%, clicking on the battery icon will report "Battery not charged" even if the charger is connected.Note that in this state, your MacBook is still powered by the charger, but the battery is no longer charged.
For some reason, macOS will always try a few percent more than specified.For example, if you set the charge to 80%, it will stop charging around 83%, so be patient.
It is important to note that keeping the battery at a low percentage (eg 20-80%) for several weeks without a full cycle (100%-0%) may cause the battery calibration to be disturbed.When this happens, your Macbook may shut down with 40-50% remaining, or your battery capacity will drop significantly.
Of course it doesn't matter, it's just because the battery calibration is disturbed, not because the battery is faulty or degraded.But to avoid this problem, we recommend at least one full cycle (0%-100%) every two weeks.Even if your battery calibration is disturbed, completing 4+ full cycles will recalibrate your battery and the capacity will rise again.
There is also a paid version of the app, AlDente Pro. AlDente Pro has more features such as thermal protection, sailing mode, recharge, calibration mode... It offers a better design and has real-time status icons.If you want to get these features, consider purchasing the paid version.
Although the function of AlDente is simple, it can effectively avoid overcharging of the battery, which is sufficient for long-term power supply scenarios.
Due to the limitation of its own materials, lithium batteries will inevitably experience irreversible loss over time.Whether it is the built-in "Optimize Battery Charging" function of macOS, or the use of AlDente Pro to optimize the charging process, it can only slow down the speed of battery consumption, and cannot achieve zero consumption.In order to maintain battery performance as much as possible, it is most important to use a regular and qualified charger and cable and maintain good charging habits.
