A degraded battery will not regain its original autonomy, regardless of the software settings. macOS includes a simple tool for checking this.<\/p>\n\n<h3>On macOS Ventura and later versions<\/h3>\n\n<p>Open <strong>System settings<\/strong>, click on <strong>Battery<\/strong> in the sidebar, then on <strong>Battery status<\/strong> (to the right of the graph). You'll see two key pieces of information: maximum capacity as a percentage and general status (Normal, Service Recommended or Needs Replacing).<\/p>\n\n<h3>On previous versions of macOS<\/h3>\n\n<p>Hold down the <strong>Option<\/strong> and click on the battery icon in the menu bar. The status is displayed directly: Normal, Replace soon, Replace now or Repair battery.<\/p>\n\n<table class=\"tg-table\">\n<thead>\n<tr>\n<th>Maximum capacity<\/th>\n<th>Status<\/th>\n<th>What it means<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span class=\"cell-label\">90 to 100 %<\/span><\/td>\n<td>Excellent<\/td>\n<td><span class=\"cell-desc\">Battery in perfect condition, near-new autonomy<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">80 to 89 %<\/span><\/td>\n<td>Good<\/td>\n<td><span class=\"cell-desc\">Normal wear and tear, moderate loss of independence<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">70 to 79 %<\/span><\/td>\n<td>Downgraded<\/td>\n<td><span class=\"cell-desc\">Significant loss of autonomy, replacement to be considered<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Less than 70 %<\/span><\/td>\n<td>Used<\/td>\n<td><span class=\"cell-desc\">Replacement recommended, battery life greatly reduced<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n<div class=\"info-box tip\">\n<strong>Good to know:<\/strong> Apple considers a MacBook battery to be in good condition as long as it retains 80 % of its original capacity after 1000 charge cycles. If your MacBook is new and already showing less than 85 %, this may indicate a fault covered by the warranty.\n<\/div>\n\n<h2 id=\"cycles-charge\">Understanding load cycles<\/h2>\n\n<p>A charge cycle corresponds to using 100 % of the battery's capacity, but not necessarily all at once. If you use 60 % of the battery one day and 40 % the next, you have completed one cycle, even if you have recharged in between.<\/p>\n\n<p>The life of a MacBook battery is measured in cycles:<\/p>\n\n<table class=\"tg-table\">\n<thead>\n<tr>\n<th>MacBook model<\/th>\n<th>Maximum recommended cycles<\/th>\n<th>Typical range new<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span class=\"cell-label\">MacBook Air M1\/M2\/M3<\/span><\/td>\n<td>1000 cycles<\/td>\n<td><span class=\"cell-desc\">15 to 18 hours<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">MacBook Pro 14\/16\u2033 M1 Pro\/Max and more<\/span><\/td>\n<td>1000 cycles<\/td>\n<td><span class=\"cell-desc\">2 to 10 p.m.<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">MacBook Pro 13\u2033 Intel (2016-2020)<\/span><\/td>\n<td>1000 cycles<\/td>\n<td><span class=\"cell-desc\">8 to 10 hours<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Intel MacBook Air (2018-2020)<\/span><\/td>\n<td>1000 cycles<\/td>\n<td><span class=\"cell-desc\">10 to 12 hours<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">MacBook Pro 15\u2033 Retina (2012-2015)<\/span><\/td>\n<td>1000 cycles<\/td>\n<td><span class=\"cell-desc\">7 to 9 hours<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n<p>To find out how many cycles your battery has: click on the Apple menu, keep <strong>Option<\/strong> and click on <strong>System information<\/strong>, then select <strong>Power supply<\/strong> in the sidebar. The number of cycles is displayed under \u00abBattery information\u00bb.<\/p>\n\n<h2 id=\"applications-energivores\">Solution 1: Identify energy-hungry applications<\/h2>\n\n<p>The battery icon in the menu bar is your best ally. Click on it and macOS will show you the applications that are currently using the most energy. If you see \u00abApplications using a significant amount of energy\u00bb, click on the name of the application to bring it to the foreground and decide whether you can close it.<\/p>\n\n<p>For a more detailed view, open the <strong>Activity monitor<\/strong> (Applications, Utilities, Activity Monitor) and click on the <strong>Energy<\/strong>. The \u00abEnergy impact\u00bb column shows current consumption, while \u00abEnergy averaged over 12 hours\u00bb gives an overview of the day.<\/p>\n\n<p>The applications that consume the most energy on a daily basis are generally browsers with lots of tabs, videoconferencing tools (Zoom, Teams), creative software (Photoshop, Final Cut Pro), email clients that are constantly synchronising and applications that run in the background without you knowing it (Dropbox indexing, Spotlight rebuilding, etc.).<\/p>\n\n<div class=\"info-box warning\">\n<strong>Please note:<\/strong> Some applications, such as Google Chrome Helper or WindowServer, are not malware. They are system processes or sub-processes of legitimate applications. Don't force them to quit without understanding their purpose.\n<\/div>\n\n<h2 id=\"luminosite-ecran\">Solution 2: adjust brightness and True Tone<\/h2>\n\n<p>The display is the component that consumes the most energy on a MacBook. Reducing brightness from 100 % to 50 % can add one to two hours of battery life, depending on the model. This is the setting that has the biggest immediate impact.<\/p>\n\n<p>To adjust brightness, use the <strong>F1<\/strong> (decrease) and <strong>F2<\/strong> (increase) on the keyboard. You can also go to <strong>System settings<\/strong>, then <strong>Screens<\/strong>, and drag the brightness slider.<\/p>\n\n<p>Also activate the <strong>automatic brightness<\/strong> In System settings, then Displays, tick \u00abAutomatically adjust brightness\u00bb. The ambient light sensor will adapt the brightness to the lighting in the room, saving energy in dark environments.<\/p>\n\n<p>Le <strong>True Tone<\/strong>, available on MacBooks since 2018, adapts the colour temperature to the ambient lighting. It consumes very little energy and improves visual comfort, so leave it on.<\/p>\n\n<h2 id=\"reglages-energie\">Solution 3: optimise energy settings<\/h2>\n\n<p>macOS offers specific settings to extend battery life. Here are the settings to check:<\/p>\n\n<p>Open <strong>System settings<\/strong> and click on <strong>Battery<\/strong>. Activate the <strong>Energy saving mode<\/strong> when you need maximum autonomy. This mode reduces the processor frequency, reduces brightness and disables certain background tasks.<\/p>\n\n<p>You can set the power-saving mode to activate automatically when MacBook is not plugged in: choose \u00abBattery only\u00bb from the drop-down menu next to \u00abPower-saving mode\u00bb.<\/p>\n\n<table class=\"tg-table\">\n<thead>\n<tr>\n<th>Setting<\/th>\n<th>Where to find it<\/th>\n<th>Impact on autonomy<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span class=\"cell-label\">Energy saving mode<\/span><\/td>\n<td>System settings, Battery<\/td>\n<td><span class=\"cell-desc\">Savings of 1 to 3 hours depending on the load<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Put disks on standby if possible<\/span><\/td>\n<td>System settings, Battery, Options<\/td>\n<td><span class=\"cell-desc\">Modest gain, useful on Macs with hard disk<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Turn off the screen after 2-3 min<\/span><\/td>\n<td>System settings, Lock screen<\/td>\n<td><span class=\"cell-desc\">Significant gain if you often leave the office<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Reducing animations<\/span><\/td>\n<td>System settings, Accessibility, Display<\/td>\n<td><span class=\"cell-desc\">Marginal but cumulative gain<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Dark mode<\/span><\/td>\n<td>System settings, Appearance<\/td>\n<td><span class=\"cell-desc\">Significant gains on MacBooks with OLED screens (M3 Pro\/Max and above)<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n<div class=\"info-box tip\">\n<strong>Tip:<\/strong> On MacBook Pros with mini-LED or OLED displays, dark mode actually reduces power consumption because the black pixels consume less power. On conventional LCD screens (MacBook Air, MacBook Pro 13\u2033), the impact is negligible because the backlight remains active.\n<\/div>\n\n<h2 id=\"bluetooth-wifi\">Solution 4: Disable Bluetooth and Wi-Fi when they are not needed<\/h2>\n\n<p>Bluetooth and Wi-Fi consume energy even when no device is connected, because the chips remain in search mode. If you're working offline on a document or creative project, switching off these connections can save 30 to 45 minutes of battery life.<\/p>\n\n<p>To quickly deactivate Bluetooth, click on the Bluetooth icon in the menu bar and select \u00abDeactivate Bluetooth\u00bb. For Wi-Fi, click on the Wi-Fi icon and select \u00abDeactivate Wi-Fi\u00bb.<\/p>\n\n<p>Don't forget the Bluetooth devices that are permanently connected: AirPods, Magic Mouse, external keyboards, speakers. Each active connection consumes some energy. Disconnect any devices you're not actively using.<\/p>\n\n<h2 id=\"notifications-push\">Solution 5: Reduce background notifications and refreshes<\/h2>\n\n<p>Each push notification requires a network connection, processor processing and screen display. Multiplied by dozens of applications, these micro-sollicitations accumulate over the course of the day.<\/p>\n\n<p>Go to <strong>System settings<\/strong>, then <strong>Notifications<\/strong>. Go through the list and deactivate notifications for applications that don't really need them. Keep only email alerts, calendar alerts and work-critical applications.<\/p>\n\n<p>You can also activate the <strong>Concentration mode<\/strong> (the moon icon in the Control Centre) to temporarily block non-essential notifications. This is effective during periods of intensive work when you don't need to be interrupted.<\/p>\n\n<h2 id=\"navigateur-extensions\">Solution 6: Choose the right browser<\/h2>\n\n<p>The choice of browser has a direct and measurable impact on the battery life of your MacBook. Safari, developed by Apple and optimised for macOS, consumes significantly less energy than Chrome or Firefox.<\/p>\n\n<table class=\"tg-table\">\n<thead>\n<tr>\n<th>Browser<\/th>\n<th>Relative consumption<\/th>\n<th>Remarks<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span class=\"cell-label\">Safari<\/span><\/td>\n<td>Reference (lowest)<\/td>\n<td><span class=\"cell-desc\">Optimised for macOS, native power management, suspends inactive tabs<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Firefox<\/span><\/td>\n<td>+15 to 25 % vs Safari<\/td>\n<td><span class=\"cell-desc\">Better than Chrome, strict protection mode reduces ad scripts<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Chrome<\/span><\/td>\n<td>+25 to 40 % vs Safari<\/td>\n<td><span class=\"cell-desc\">Processes separated by tab, extensions often greedy<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Arc<\/span><\/td>\n<td>+20 to 30 % vs Safari<\/td>\n<td><span class=\"cell-desc\">Based on Chromium, overconsumption linked to Boosts and spaces<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n<p>If you can't give up Chrome (professional extensions, compatibility), at least reduce the number of tabs you open and deactivate unnecessary extensions (Menu, Extensions, Manage extensions). Some extensions, such as ad blockers, paradoxically reduce consumption by preventing advertising scripts from running.<\/p>\n\n<h2 id=\"mise-a-jour-macos\">Solution 7: Update macOS<\/h2>\n\n<p>MacOS updates often include power management optimisations that improve battery life. Apple regularly fixes bugs that cause abnormal discharge: a system process that runs in a loop, a poorly optimised graphics driver, a bug in the management of standby states.<\/p>\n\n<p>Open <strong>System settings<\/strong>, then <strong>General<\/strong>, then <strong>Software updates<\/strong>. Install the available updates and restart your MacBook.<\/p>\n\n<p>After a major update, it is normal for the battery to drain faster for 24 to 48 hours. The system re-indexes Spotlight, optimises caches and performs compilations in the background. Leave the MacBook plugged in during this period so as not to distort your judgement of actual battery life.<\/p>\n\n<h2 id=\"reinitialiser-smc\">Solution 8: reset the SMC (Intel Mac)<\/h2>\n\n<p>The SMC (System Management Controller) manages the battery, charge and power on Intel Macs. A malfunction of the SMC can cause an accelerated discharge, a battery percentage that jumps erratically or a charger that is not detected.<\/p>\n\n<p>The reset procedure depends on your model:<\/p>\n\n<p><strong>MacBook with T2 chip (2018-2020) :<\/strong> switch off the MacBook <strong>Ctrl + Option + Shift<\/strong> (left side) for 7 seconds, then add the power button and hold the four buttons for 7 seconds. Release, wait a few seconds and switch on again.<\/p>\n\n<p><strong>MacBook without T2 chip (before 2018) :<\/strong> switch off the MacBook <strong>Shift + Ctrl + Option<\/strong> (left) and the power button for 10 seconds. Release and switch back on.<\/p>\n\n<div class=\"info-box warning\">\n<strong>Mac Apple Silicon (M1\/M2\/M3\/M4) :<\/strong> There is no SMC on these models. A simple reboot automatically resets the power management controllers. If you don't know which processor is powering your Mac, use our <a href=\"https:\/\/reparationmac.be\/en\/identify-your-mac\/\">Mac identification tool<\/a>.\n<\/div>\n\n<h2 id=\"charge-optimisee\">Solution 9: Activate optimised battery charging<\/h2>\n\n<p>Since macOS Big Sur, Apple has been offering a feature that extends battery life over the long term: the <strong>optimised load<\/strong>. This feature learns your charging habits and delays charging beyond 80 % until you need to use the MacBook.<\/p>\n\n<p>Why it's important: keeping a lithium-ion battery at 100 % all the time accelerates its chemical degradation. Optimised Charging keeps the battery around 80 % when the MacBook is plugged in most of the time, and only fully charges it when it anticipates that you're going to need it.<\/p>\n\n<p>To check that the function is activated, go to <strong>System settings<\/strong>, then <strong>Battery<\/strong>, then <strong>Battery status<\/strong>. The \u00abOptimised battery charge\u00bb option must be activated. This is the default setting, but some users unknowingly deactivate it.<\/p>\n\n<div class=\"info-box tip\">\n<strong>Pro tip :<\/strong> If you use your MacBook mainly connected to the mains (in the office, for example), optimised charging is particularly beneficial. It prevents the battery from remaining permanently at 100 %, which is one of the factors that most accelerates its ageing. In 15 years of repairs, we've seen a clear difference in battery life between Macs that are \u00abalways plugged in\u00bb with and without this feature.\n<\/div>\n\n<h2 id=\"remplacement-batterie\">Solution 10: Replace the battery<\/h2>\n\n<p>When software optimisation is no longer enough and the maximum capacity has fallen below 80 %, replacing the battery is the definitive solution. This is the most popular procedure at MAC Repair, and it literally gives your MacBook a new lease of life.<\/p>\n\n<img decoding=\"async\" src=\"\/wp-content\/uploads\/2026\/03\/remplacement-batterie-macbook-atelier.webp\" alt=\"MacBook battery replacement - optimise battery life\" title=\"MacBook battery replacement in the workshop at R\u00e9paration MAC in Brussels\" width=\"1200\" height=\"568\" loading=\"lazy\">\n\n<p>Signs that a replacement is needed :<\/p>\n\n<table class=\"tg-table\">\n<thead>\n<tr>\n<th>Symptom<\/th>\n<th>What it means<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span class=\"cell-label\">Maximum capacity at 80 %<\/span><\/td>\n<td><span class=\"cell-desc\">Advanced chemical wear, irreversible loss<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">MacBook shuts down at 20-30 % battery life<\/span><\/td>\n<td><span class=\"cell-desc\">Faulty calibration or damaged cells<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Battery swollen (trackpad raised, shell deformed)<\/span><\/td>\n<td><span class=\"cell-desc\">Urgent replacement, safety risk<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Autonomy of less than 2 hours in light use<\/span><\/td>\n<td><span class=\"cell-desc\">End-of-life battery<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Service recommended\u00ab message in macOS<\/span><\/td>\n<td><span class=\"cell-desc\">Apple detects a significant deterioration<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n<div class=\"info-box danger\">\n<strong>Important information:<\/strong> A swollen battery is a safety issue.

In normal use, this represents around 3 to 5 years, depending on your habits. An Apple Silicon MacBook typically offers 15 to 22 hours of new battery life, while an Intel model will last around 8 to 12 hours.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>Should you leave your MacBook plugged in all the time?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>With optimised charging enabled (by default from macOS Big Sur), you can leave your MacBook plugged in without too much worry. The system limits charging to 80 % and only tops up when it anticipates that you're going to need it. Without this feature, a battery maintained at 100 % at all times will degrade faster.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>Does energy-saving mode reduce performance?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>Yes, the energy-saving mode slightly reduces the processor frequency and brightness. For office work, web browsing and email, the difference is imperceptible. For video editing, 3D or code compilation, you will feel a slowdown. Activate it only when autonomy is a priority.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>My battery suddenly jumps from 40 % to 10 %. Is this a software problem?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>This behaviour generally indicates a hardware problem: the battery has damaged cells which are not discharging evenly. Resetting the SMC can sometimes improve calibration, but if the problem persists, a battery replacement is necessary.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>How much does a MacBook battery replacement cost?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>Prices vary depending on the exact MacBook model. At MAC Repair, our prices include the professional-quality battery, labour and a 180-day guarantee. See our <a href=\"https:\/\/reparationmac.be\/en\/mac-pricing\/\">detailed rates<\/a> to find out the price for your model.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>Does Chrome really drain the battery faster than Safari?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>Yes, the difference is documented and measurable. Chrome can consume 25 to 40 % more energy than Safari for comparable use. This is due to Chrome's multi-process architecture and the fact that Safari benefits from optimisations specific to macOS and Apple chips.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>Does dark mode really save battery power?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>It depends on your screen. On MacBook Pros with OLED screens (M3 Pro\/Max and later), yes: black pixels consume less energy. On LCD screens (the majority of MacBooks), the impact is negligible because the backlight remains active regardless of the colour displayed.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>My MacBook has been unloading quickly since the last update. What can I do?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>After a major macOS update, the system performs optimisation tasks in the background for 24 to 48 hours. Leave your MacBook plugged in during this time. If the abnormal discharge persists after 3 days, check the Activity Monitor to identify a process that is consuming power abnormally.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>Can you replace a MacBook battery yourself?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>On older models (MacBook Pro Retina 2012-2015, MacBook Air pre-2018), this is technically feasible with the appropriate tools. On recent models, the battery is glued to the chassis and disassembly requires acetone or controlled heat, which can cause damage.
