Apple's laptop battery management takes a major turn with the arrival of macOS 26.4 and its new load limitThis system update, already available in beta and scheduled for general release in the coming weeks, allows you to set a maximum charging limit for MacBooks and prevent the battery from spending hours at 100% connected to the charger, something that eventually takes its toll.
After premiering in the iPhone 15 and consolidate its presence on iOS and iPadOS, The idea of ​​limiting charging to 80% or other percentages is finally coming to the MacFor those who use their laptop as if it were a desktop computer, plugged in all day on a desk, this feature can make a noticeable difference in battery health in the medium and long term, without needing to resort to third-party applications.
What is the macOS 26.4 load limit and how does it differ from optimized load?
Until now, Macs only had the option of "Optimized battery charging"This system analyzes usage patterns and attempts to delay the final charging stage from 80% to 100% until shortly before the user is about to unplug the device. It's a feature based on algorithms and predictions, useful but not always accurate: in many cases, the laptop still reached 100% for a significant portion of the day.
With macOS 26.4, a different feature comes into play: a manual charging limit that the user can set between 80% and 100%The logic is simple: you choose, for example, 80%, and the system stops charging the battery when it reaches that point, even if the power adapter remains connected. There's no machine learning or guesswork involved; it's a clear and predictable setting.
This difference is key because Maintaining a lithium-ion battery constantly at 100% accelerates its chemical degradationThe cells suffer more voltage stress when they always work at the upper end of their capacity, and this translates into a progressive reduction of maximum autonomy over the months and years.
In that context, the new manual limit does not replace the optimized load, but rather complements it. Those who want fine control can set a stable limit (80%, 85%, 90%, 95% or 100%).Those who prefer to let the system decide will continue to have the traditional option, based on habits and usage patterns.
For users who have their MacBook almost always connected to the charger, as is the case in many offices and homes, This tool fits better with the widespread recommendation to keep the load within a more conservative range. instead of constantly abusing 100%.
Where to activate and how to configure the upload limit in macOS 26.4
Activating the function isn't too complicated, but it's worth reviewing because Apple has integrated it directly into the macOS Battery panel.Once the macOS 26.4 update is installed, the process is as follows:
- Ir a System settings.
- Enter section Battery.
- Click on the information icon ("i") next to the upload option.
- Activate the section "Load limit".
- Move the slider to set the desired percentage, between 80% and 100%.
Once adjusted, The MacBook will stop charging when it reaches the chosen limit.Apple clarifies that, occasionally, the system may automatically charge up to 100% to calibrate battery health estimates and maintain reliable readings; these are isolated exceptions, not normal behavior.
In addition to the control from Settings, macOS 26.4 incorporates a quick access feature in the battery menu of the menu bar.There you'll find the classic "Charge to 100% now" button, designed for those who normally work with a low limit but occasionally need to squeeze every last drop of available autonomy, for example before a trip or a long day away from the office.
This combination of a permanent setting in the settings panel and a temporary shortcut It allows you to play with daily autonomy without sacrificing battery life.The idea is that most of the time you work with a moderate load, resorting to the full load only when strictly necessary.
Compatibility, deployment, and beta status
The load limit is reached at macOS Tahoe 26.4This version focuses on refining the Mac experience with Apple Silicon and definitively leaving Intel-based computers behind. The new feature is available in the first developer beta and will be rolled out to other users as Apple releases public beta versions.
In practice, The feature is aimed at MacBooks with Apple Silicon chips (M1 family and later)These are the models on which Apple is focusing its energy management improvements. The company hasn't yet released a definitive list of compatible devices or specific requirements, but all indications suggest that recent laptops will be the ones that truly benefit from the feature.
For those who want to try it as soon as possible, the process involves the beta channel: Developers can register on Apple's official portalSelect macOS 26 beta updates in System Settings > General > Software Update and install version 26.4. The public beta should appear shortly after, within a few days.
It should be borne in mind that Beta versions may contain bugs, abnormal resource consumption, or unexpected behavior.If your Mac is your primary work tool, it's wisest to wait for the stable version or, at least, install the beta on a secondary partition or on a computer that isn't critical for daily use.
Despite these precautions, the schedule is fairly well defined: Apple is aiming for a general release of macOS 26.4 between the end of March and the first weeks of Aprilwhich fits with their usual pace of intermediate system updates.
Why limiting charging to 80% helps battery health
The batteries used in MacBooks are made of Lithium-ion batteries, the same technology found in most current laptops and mobile phones.They have improved a lot compared to previous generations (no memory effect and with more precise electronic control), but they still have known weaknesses: heat, charging cycles and voltage extremes, both above and below.
One of the factors that most influences degradation is to keep the battery at 100% for long periods of timeWhen a laptop is plugged in permanently and the battery is fully charged, the cells experience increased stress and wear accelerates. This isn't something you'll notice overnight, but after months of continuous use, the maximum capacity gradually decreases and actual battery life is reduced.
That's why many experts have been recommending it for years. operate in a more moderate range, usually between 20% and 80%This margin reduces chemical and thermal stress and allows the battery to better maintain its capacity over cycles. It doesn't prevent degradation—which is inevitable—but it can significantly slow it down.
The new feature in macOS 26.4 aligns perfectly with that idea: It offers a configurable limit between 80% and 100%.This allows those who prioritize the component's health to set a more conservative limit. For desktop use, where the laptop spends most of its time plugged in, sacrificing 20% ​​of daily capacity is usually acceptable.
There are other factors that remain important: Avoid high temperatures during charging; do not leave the device completely discharged for weeks., Use original or certified chargersand avoid putting excessive strain on the hardware while fast charging. The charging limit does not replace these best practices, but it reinforces them by reducing continuous exposure to 100%.
Goodbye (in part) to third-party apps like AlDente
Until the arrival of macOS 26.4, Those who wanted strict control over the load level relied on third-party toolswith AlDente being one of the most popular solutions. These applications have allowed users to set load limits for years, often with advanced features, but at the cost of special permissions, extra resource consumption, and, in some cases, paid versions.
With the new system, Apple natively integrates one of the star features offered by these appsFrom System Settings, you can set a hard limit between 80% and 100% without installing anything additional. For most users, this level of control will be sufficient and will reduce the need for external software.
Still, Third-party tools don't disappear overnightThose who need more extreme configurations—for example, limiting the charge below 80%, or combining several advanced profiles—will continue to find features in these apps that Apple's system does not currently support.
This is still a common move within the company's ecosystem: When a feature becomes almost standard, Apple tends to include it as a standard feature. to cover the most common needs. In this case, battery management was one of the most frequent requests from users looking to extend the lifespan of their laptops without too much hassle.
Integration with Shortcuts and automated loading
One of the less noticeable new features at first glance, but very interesting in everyday use, is that The load limit is also integrated with the Shortcuts app This applies to both macOS 26.4 and the beta versions of iOS 26.4. This opens the door to automating when and to what extent the device is charged.
Thanks to this integration, It is possible to create automations that change the maximum percentage based on the time, location, or context.For example, you could set an 80% limit while your Mac is plugged in at home and allow it to charge to 100% overnight before a trip, all automatically.
These types of adjustments were previously the exclusive domain of specialized and, in many cases, paid applications. With Shortcuts, Apple offers a more transparent and secure solution, integrated into the system itself.which also benefits from continuous improvements to the automation platform.
The company has not provided specific figures on how much battery life can be extended with these features active, but He emphasizes that reducing the time spent on the task by 100% is beneficial.In practice, the improvement will depend on the specific use, the ambient temperature, and the quality of the hardware, but the technical basis is solid.
A change that is especially relevant for Europe and intensive desktop use.
In the European market, where The MacBook has established itself as a standard tool in professional, educational, and home environments.The introduction of the load limit comes in a particular context: more expensive equipment, greater concern for durability and a growing interest in repairability and the reduction of electronic waste.
Replacing a laptop battery isn't exactly cheap or easy, and in many cases it involves going to an authorized service center. Therefore, The fact that the system incorporates clear tools to preserve this key component fits with the regulatory and social pressure in the European Unionwhere incentives are given for devices to last longer and generate less waste.
In very common scenarios—working from home, offices with the laptop docked in a dock, workstations in universities—the MacBook spends hours and hours plugged in. It is precisely in these cases where the 80% load limit makes the most senseThe extra autonomy lost in day-to-day use is minimal, but the impact on degradation can be noticeable in the medium term.
The industry as a whole has been moving in this direction for some time. Other manufacturers already offered conservation modes with similar load limitsAnd some hardware experts have recommended for years avoiding both deep discharges and continuous full charges. Apple's adoption of this philosophy in macOS brings it closer to a de facto standard in battery management.
For the average user, the message is quite clear: If your MacBook is almost always plugged into a power outlet, enabling charging limits in macOS 26.4 is one of the easiest ways to protect your battery.You don't need to be particularly technical or install anything unusual; simply adjust a slider and let the system take care of the rest.
Overall, the arrival of the charging limit in macOS 26.4 means that MacBooks are catching up with the most widespread recommendations on lithium batteries and with features that were already present in iPhones, iPads, and laptops from other manufacturers. Manual control between 80% and 100%, integration with Shortcuts, and compatibility with optimized loading They allow each user to choose the balance between immediate autonomy and the longevity of the equipment, something especially valuable at a time when extending the useful life of devices is almost as important as getting the latest model.
