MacOS menu bar tool to limit maximum charging percentage and improve battery lifespan
Li-Ion batteries (like the one in your MacBook) last the longest when operating between 20 and 80 percent. Keeping your battery at 100% at all times can shorten the lifespan of your MacBook significantly. More information can be found at Battery University.
AlDente Pro is our paid version of AlDente. It has many more features such as Heat Protection, Sailing Mode, Top Up, Calibration Mode,... It offers a better design and has live status icons. If you are interested in getting the most out of your battery, check out our website.
AlDente Pro is now available on Setapp too.
- Charge Limiter allows you to set your maximum charging percentage between 20 and 100 percent. You can either set it by using the slide bar or by typing in the desired percentage in the field above and pressing Enter afterwards. Read more about the Charge Limiter feature in this article "Feature Explanation: Charge Limiter".
- Discharge - This feature allows your MacBook to run completely on Battery even if it is plugged in. Therefore, you can actively discharge your MacBook to a healthier percentage. Unfortunately, while Discharge is activated, clamshell mode is not supported due to technical limitations. Read more about the Discharge feature in this article "Feature Explanation: Discharge".
Check out if your MacBook is supported on our FAQ page.
You can download the app from GitHub: https://github.com/davidwernhart/AlDente/releases
An installation guide can be found on our website:Installation Guide
When the installation is finished, enter your desired max. charging percentage by clicking on the AlDente icon on your menu bar. Usually, the operating system will take a minute or two to register the changes, so be patient. You can check if it's working by setting the max. percentage to e.g., 80%. After a while, clicking on your battery icon will report "Battery is not charging" if you have more than ≈73% left, even though your charger is connected. Notice that in this state, your MacBook is still powered by the charger, but the battery is bypassed and not charging anymore.
IMPORTANT: Keeping your battery at a lower percentage, such as under 80%, for weeks without doing full cycles (100%-0%) can result in a disturbed battery calibration. When this happens, your MacBook might turn off with 40-50% left, or your battery capacity will drop significantly. However, this is only due to a disturbed battery calibration and not because of a faulty or degraded battery. To avoid this issue, we recommend doing at least one full cycle (0%-100%) every two weeks. Even if your battery calibration gets disturbed, doing 4+ full cycles will recalibrate your battery, and the capacity will go up again.

This project is no longer open source. Although the GitHub repository contains legacy code and archived releases, the current version of the software is proprietary and closed‑source.
I do not take any responsibility for any sort of damage as a result of using this tool! Although this had no negative side effects for me and thousands of others, AlDente still taps into some very low-level system functions that are not meant to be tampered with. Use it at your own risk!
