As you likely have sex , abattery ’s commission capacity diminishes over fourth dimension . If you ’ve lately draw an M - series MacBook , you spent a upright amount of money on that laptop computer , so you need the battery to be viable as long as potential . luckily , macOS has built - in ways to help conserve your battery ’s condition .
In macOS Sonoma , the Battery System scope provides salutary info you could use to determine your assault and battery ’s wellness . There ’s a chart that displays your assault and battery kick grade over the last 24 hr and the last 10 day . Another chart shows screen usance – the MacBook ’s projection screen is one of the most major power - hungry ingredient .
But there ’s a background that ’s not obvious in the Battery pill in System options . It ’s called optimize Battery Charging , and we ’ll cover what it ’s about and why you should be using it .
Optimiize Battery Charging is found inSystem Settings>Battery; click the Info icon in theBattery Healthsection.
What is Optimize Battery Charging?
In macOS Catalina , Apple introduced aBattery Health Managementsetting that evolve into optimize Battery Charging in late interpretation of macOS . Optimized Battery Charging “ learns from your day-to-day charge subroutine so it can wait to end rouse past 80 percent until you need to habituate it on assault and battery ” to slow up down the battery aging process , according to Apple .
In other words , with Optimized Battery Charging on , the MacBook battery charge to 80 per centum and plosive consonant . Then , macOS uses an algorithm based on your usage to determine when the battery should be charged to 100 percent .
If you have a steady daily routine , this setting works well . For object lesson , if you usually spend the mornings using your MacBook on battery , and then the afternoon and evenings are punch in , Optimized Battery Charging can set the charging cycle so that the barrage fire is charged up to 80 percent after you plug away in , then shoot to 100 percent before you go on battery in the dawning .

Many Macworld referee have noticed that even with Optimized Battery Charging on , the MacBook electric battery gets charge to 100 percent , without regard to a person ’s routine . Apple has not explained this ; Mac 911 editorialist Glenn Fleishmanthinksthat it ’s because a MacBook uses very niggling get-up-and-go when not in use and the cover is bleak , so the stamp battery still charge up to 100 percentage . In that berth , Apple ’s algorithm say charge to 100 per centum is idealistic – so little power is used that there are n’t big enough fluctuations in charging / discharging that would adversely affect assault and battery viability .
optimize Battery Charging is turned on by default , so there ’s a skillful chance you ’ve had it on for a considerable amount of time . If you do n’t finger like it ’s knead , there ’s a theory that the algorithm ca n’t learn when a MacBook is plug away in before turning it on . You may need to turn off the setting , disconnect the might , re-start the MacBook , turn it back on , and then plug the MacBook in to get the algorithm crop .
In my experience , it does n’t ache to keep Optimized Battery Charging switched on whether you have a regular battery - function routine or not . My function is temporary , and with the place setting on , I ’ve never had an instance where the battery was n’t at 100 percent when I needed it to be .

How to adjust the Optimize Battery Charging setting
Accessing the Optimized Battery Charging place setting is n’t obvious . Go to System configurations > Battery , and in theBattery Healthsection , sink in the Info picture ( the “ i ” in the circle ) . A Modern window appear , and you ’ll regain a electric switch for Optimize Battery Charging . Apple turns it on by default , but if you want to turn it on or attempt to recalibrate it , you could do that here .
observe that you could not set up macOS to blame up to 80 percent and blockade . You ca n’t do this on older iPhones , either , butyou can do this with the iPhone 15 and iOS 17 . Apple has never officially stated why this is . Perhaps it ’ll transfer in a future macOS update .
