The battery packed inside your electronics gadget — such as iPhones and MacBooks — is a perishable item . Over the course of repeat charge - discharge oscillation , it lose its mojo due to electrochemical degradation . When that materialize , the stamp battery bit by bit loses its ability to retain electric charge .
As a result , your devices tend to last few hours , even thoughMacBooks have a better record at itthan Windows machines . As the battery lose its ability to furnish enough succus for a sustained flow of time , sure performance optimizations ( read : slower performance ) kick into natural process . Soon , you are left with no other alternative thangetting a battery refilling .
Now , there is no magical pill to avoid battery degradation . What we can do , however , is somehow slow down the electrochemical abjection so that the battery survive longer . Apple lets iPhone users do thatby let them confine the charging to the 80 % level . unluckily , no such answer exists for MacBooks .

What’s the solution?
The Mac developer and open - germ community have create a smattering of battery direction tools over the years . But as Apple shifted from Intel to in - theatre silicon , many of those projects vanished , while the remaining few are pretty expensive .
One such shaft that I recently came across — and which gets the job done — wasActually Mentor . This free and open - germ software has one core objective , which is to restrict your MacBook ’s assault and battery to the 80 % grade . Though it only work on Apple atomic number 14 , it has been fork with flourish Si backing and more feature , too .
The app is as simple as it mystify . It subsist within the menu bar and only extend a minor drop - down window as its substance abuser user interface . Installation is fairly square , and all you need to do is give admin access for get it running .

As far as functionality goes , all of it revolves around the 80 % bearing limit . If the assault and battery is above that level , the app can manually discharge it to reach out the target , even if the charging cable is plugged in .
While load , as soon as the battery give an 80 % layer , further top - up is pause . And as shortly as the tank send packing below that baseline , charging is resumed . In a nutshell , your MacBook will never go past a certain spirit level .
Thankfully , the app ’s functionality is active even if you fold it , or the scheme reboots . If you attempt more controls , I ’d commend an Actually Mentor crotch namedBattery Optimizer for Mac .

This one works with Intel and Apple atomic number 14 Macs , replaces the macOS battery icon with a computer hardware - base charging level indicant , allows occasional standardisation , temporarily allow a full charge , creates a log , and shows status reports , as well .
Why do I need one?
There are two interrogative you might ask before installing an app like Actually Mentor . First , does maintain an 80 % charge service line even matter ? secondly , what about optimize Charging that Apple already offers ? Well , let ’s protrude with the first dilemma .
enquiry suggests that Li ion batteries — the kind you will find inside laptops — undergo stress when subjected to high temperatures . Likewise , if a battery pack is constantly maintain at a high electric potential potential , the ionic authorship is stressed .
Ideally , a lithium ion cell should not stay on at the emf cap prescribe for common electronics gadgets for an extended period . For lithium - based barrage , a reducing in peak charge emf can aid prolong their life by one C of cycles .

Then there ’s the interrogation of capacity loss , which look on the deepness of power discharge . test suggest that discharge beginning around the 85 % grade offers the better battery longevity , though the miserable boundary might alter .
“ A laptop battery could be keep up by turn down the charge potential drop when connected to the AC control grid , ” says a detailedtechnical analysis . “ To make this feature article user - friendly , a gimmick should feature a Long Life mode that continue the battery at 4.05V / cell and offers a SoC of about 80 percent . ”
This is where tools like Actually Mentor andAl Dentecome into the picture . Now , let ’s speak the interrogative sentence about Optimized Charging , which is broil at the system level within macOS .
Apple
Well , it does n’t technically limit the charging level to the 80 % sucker , but only slows down further top - up , a terminus commonly known as dribble charging . “ Your Mac delays charge past 80 % when it bode that you ’ll be plug in for an extended point of time , and aims to fully charge the battery before you unplug , ” explain Apple .
What’s the best way forward?
The folks behind Al Dente suggest that a charge demarcation between 50 - 80 % should keep your MacBook ’s bombardment in optimal conformation for the longsighted run . Actually Mentor , on the other hand , have a more straightforward approach and locks the upper limit to 80 % for charging without addressing the lower limit for discharging .
As a substance abuser , I would prefer the latter approach , as it keep thing round-eyed . Moreover , you’re able to choose to enable or disable this limit without going through any technical hoop . If you are someone who intends to get the most out of their Mac ’s battery life , in reality Mentor is the cleanest usefulness for your Apple laptop computer .
Of course , it goes without saying that you should stick to with the official charging brick , or prefer only those third - party alternative that meet Apple ’s voltage and current criteria to juice up a MacBook ’s shelling . Poor quality chargers often lead to overheating and suffer from unregulated potential difference fluctuations , which can chop-chop reverse into a fire hazard , as well .
In a nutshell , do n’t stray too far from Apple ’s hardware bundle . And where there are software program break , fill them with running utilities such as Actually Mentor . It ’s just a sweet bonus that this is an undefended - generator project that is always evolving from the feedback of an average substance abuser like me , and you .
