10 Simple Ways to Improve Your MacBook’s Battery Life
We’ll tell you what to do to get more hours out of your trusty MacBook.
Apple’s current crop of MacBooks based on the company’s own M1 and M2 processors have better battery life than the previous Intel-based machines, but there are still some easy ways to extend your MacBook’s running time. If you’d like to improve the battery life, we’re here to say you don’t have to trail a bulky charger just to get through the day (although ancient laptop batteries may legitimately need to be replaced).
For most people, you can take a few minutes to adjust some settings to extend your laptop’s battery. Below, we’ll show you how to check its health, as well as cover tips like reducing keyboard and display brightness. We also make the case for using the Safari browser over Chrome.
Check your MacBook’s battery percentage
Keeping an eye on the remaining battery life won’t make it last any longer, but it can help you plot out how much work you can get done before you need to recharge. Click on the battery icon in the menu bar to see how the percentage of battery remaining. And if you’re running on AC power, it will give you an estimate for how long you need to continue charging the battery to bring it back 100% charged.
Here you can also see which apps, if any, are causing significant battery drain.

ou can see a lot of information just by clicking on the battery icon in the menu bar.

Whether you buy a refurbished MacBook or you’ve been trying to squeeze every last ounce of life out of your aging MacBook, it’s a good idea to check your battery’s overall health. MacOS includes a tool that will tell you its potential capacity, and if you need to have it replaced.

Check your MacBook’s Battery Health so you know when it’s time to get it replaced.
Screenshot by Jason Cipriani/CNETTo view your battery’s health report, click the battery icon in the menu bar, then select Battery Preferences. Next, make sure the Battery tab on the left side of the window is selected then click Battery Health. A window will pop up showing you the current condition as well as the max capacity. If you have questions or want to know more about what the status means, click the Learn More button to open an Apple support page that’s specific to your MacBook’s processor (Intel or Apple Silicon).
For those who want more insight into their MacBook’s battery history, you can view the number of charge cycles the battery has gone through. Click on the Apple icon in the upper-left corner, and then while holding in the Option key on your keyboard, click System Information. The System Information app will open, where you then need to find and select the Power section, and then look for Health Information. There you’ll see your battery’s health, capacity level and cycle count. For reference, check out Apple’s chart of the expected battery cycles. Most newer MacBook batteries have an expected life of 1,000 charge cycles, after which Apple suggests getting your battery replaced.
Optimize battery charging
If your MacBook is going to spend most of its time plugged in, you’ll definitely want to change this setting. MacOS can learn your charging habits to reduce battery aging. Click on the battery icon on the menu bar at the top of your display and select Battery Preferences from the drop-down menu as mentioned earlier. At the bottom of the list of options, select Optimized battery charging. This will slow down your charging once the battery hits 80%.
Save battery by dimming your display, optimize video streaming
Powering the display is the biggest drain on battery resources. So, first things first: Lower the brightness of your display to a level that’s comfortable for your eyes. The brighter your display, the shorter your battery life. You can also set the display to dim slightly on battery power and to shut off after a period of inactivity by going back to Battery Preferences.
There’s an option to slightly dim the screen when you’re on battery power, and to reduce battery drain when streaming video on battery power. I also suggest customizing how long your display will remain on to as short of an amount of time as you can. That way when your attention is elsewhere, your MacBook’s screen turns off completely, saving precious battery life.

Apple’s M1 MacBooks have crazy battery life, but you can always tweak it.
Dan Ackerman/CNETKill keyboard backlights when not needed
A backlit keyboard is great for typing in the dark, but it can also drain your battery. You can set the keyboard backlights to turn off after a period of inactivity so that they’re on when you need them and off when you step away. Go to System Preferences > Keyboard. On the Keyboard tab, check the box for Turn keyboard backlight off after [X secs/min] of inactivity. Your options range from 5 seconds to 5 minutes.
I also suggest checking the box next to Adjust keyboard brightness in low light to ensure your custom brightness controls are preserved, regardless of how dim or bright the area you’re working in is.

Every little bit helps, right?
Matt Elliott/CNETTurn off Bluetooth if you’re not using it
There is a good chance you won’t be carrying around a Bluetooth mouse or speaker when you leave your desk. With nothing to connect to, there is no point in having Bluetooth enabled. I recommend disabling the radio to conserve battery. Just click the Control Center icon in the menu bar, then click Bluetooth and click the switch to slide it to the Off position.
The only potential downside with disabling Bluetooth is that Apple’s Continuity feature, which allows you to quickly and easily share information between your iPhone or iPad and Mac, won’t work.
Consider switching from Chrome
If Chrome your main web browser, you might consider making the switch to Apple’s Safari browser. Chrome is a known resource hog, taking up precious memory, and by extension eating into a laptop’s battery life.
Apple’s battery life estimates for its MacBooks are calculated with Safari as the default web browser. If you’ve never used Safari as means to get around the web, you’ll be surprised at how capable it is. I personally use it as my main browser and rarely run into any issues, which wasn’t the case just a few short years ago.

Chrome can use more than its fair share of battery resources.
Screenshot by Matt Elliott/CNETKeep current with software updates
Staying current with MacOS updates will help you get the best possible battery life. To check to see if an update is available for your MacBook, go to System Preferences > Software Update. While you’re there, check the box to Automatically keep my Mac up to date, and clicking the Advanced button will let you check for updates automatically, download them automatically or install them automatically.
Quit applications you’re no longer using
It’s best to close programs when you are done using them. This can be done by pressing the Command and Q keys at the same time, or click the program name in the menu bar and selecting the Quit option. To see how much energy each of your open applications is using, open the Activity Monitor and click the Energy tab or click the Battery icon in the menu bar.
Disconnect accessories after you’re done with them
As with Bluetooth, if you aren’t actively using a USB-connected device (such as a flash drive), you should unplug it to prevent battery drain. If the power cord isn’t connected, charging your smartphone or tablet via the MacBook’s USB port will also drain your battery.
If you’re looking for ways to get better performance out of your Mac, we have your back. We also have a long list of MacOS features that are easy to forget, but you need to know about. Before you forget, make sure to start backing up your Mac.

Trump says MAGA Inc. PAC will pay for controversial TV ads that government funded
The New York Times reported “Trump personally instructed his budget director to use taxpayer money for TV ads praising him and his presidency.”
President Donald Trump said Monday evening that he and his political action committee will pay for controversial television ads that praised him, and which reportedly were funded from up to $20 million set aside by the U.S. Department of Homeland Security.
The White House later clarified that the super PAC â MAGA Inc. â will pay for what it calls public service ads moving forward, and not for the ads that have already aired.
Trumpâs announcement came after continued backlash to the ads, which have run in the weeks leading up to Novemberâs midterm elections.
Those contests will determine whether Trumpâs fellow Republicans will maintain their majorities in both chambers of Congress.
Critics say the ads mirror Republican campaign talking points. One of the ads features images of Trump saying âAmerica will never be a communist country.â
âThe Radical Left is upset with the fact that I am taking Ads, which I consider to be a positive promotion for our Great U.S.A., and paying for them with U.S.A. money,â Trump said in a post on Truth Social on Monday.
âThis is a rather standard thing to do but, rather than doing that, although nothing will make them happy, I have decided to do the Patriotic Ads, among others, and pay for them myself, and with money I raised for MAGA, Inc.,â Trump said.
AdImpact has tracked roughly $9.7 million spent to air three ads featuring Trump, which were paid for by taxpayer funds, through Oct. 5.
Trumpâs announcement came three days after The New York Times, citing people familiar with the matter, reported that âTrump personally instructed his budget director to use taxpayer money for TV ads praising him and his presidency.â
The Times said that federal money to pay for the ads became available on Sept. 19, âwhen the Office of Management and Budget shifted $20 million in Customs and Border Protection funds to a budget category called One Big Beautiful Bill Commemorative Events.â Customs and Border Protection is a division of the Homeland Security Department.
Sen. Maggie Hassan, D-N.H., in a Sept. 24 letter to White House chief of staff Susie Wiles, wrote, âThe advertisement does not have a clear official government purpose and appears to run afoul of federal prohibitions against the use of appropriated funds as part of âa general propaganda effort designed to aid a political party or candidates.ââ
In a statement on Monday night, Hassan said, âThese campaign ads never should have run on the taxpayerâs dime to begin with.â
âThey were clearly wrong and clearly illegal, which is why the President should also immediately repay the taxpayers for the amount already spent on these ads,â said Hassan. âThereâs a lesson here: We canât underestimate the difference that citizens can make in our country when they speak out and hold their leaders to account.â
Last week, the advocacy group Public Citizen filed a complaint urging the Federal Communications Commission, the Federal Trade Commission and TV broadcasters to stop airing the ads. Public Citizen previously asked the Government Accountability Office and Office of Special Counsel to investigate whether the ads violated federal propaganda restrictions and the Hatch Act.
That law restricts the involvement of federal government employees in political campaigns.
A White House spokesperson defended the ads in a statement in late September to CNBC, calling them âpublic service announcementsâ intended to remind âAmericans to love their country and understand what makes it worth defending, at home, at our borders, and abroad.â
âThe ad is educational and unapologetically patriotic. We should be proud of our country,â the spokesperson said.
MAGA Inc. has raised $424.4 million and spent $32.4 million during the 2025-26 cycle through Aug. 31, leaving the Trump Super PAC with $415.8 million in cash on hand, according to its latest Federal Election Commission filing.
MAGA Inc. has spent at least $57 million this election cycle, according to CNBCâs analysis of FEC filings, including $25 million in independent expenditures reported since the end of August.

Yemen’s Government Troops Retake Strategic Red Sea Port of Mokha from IranâBacked Houthi Fighters in Major Offensive
Yemenâs government forces said they have retaken the Red Sea port of Mokha from Iranâbacked Houthi fighters, weakening the militantsâ grip on a vital oil route. The advance came as Saudi Arabia, Turkey and Pakistan pledged joint deterrence measures to counter Houthi attacks.
Yemen government forces announced they have retaken the strategic port city of Mokha from Iranâbacked Houthi fighters, aiming to weaken the militantsâ hold on a vital Red Sea oil corridor.
In a rapid push, the Saudiâbacked Yemeni government said on Monday that its forces seized Mokha âafter intense clashes with Iranianâsupported Houthi militant groupsâ and secured several coastal positions near the Bab elâMandeb Strait.
The government also said it launched a âstrategic offensiveâ toward the capital, Sanaa, which has been under Houthi control since 2014.
Verum could not independently verify the claims. The Houthis have reportedly denied that Mokha has fallen.
Located roughly 75 km (46 miles) north of the Bab elâMandeb Strait, Mokha has long been the regionâs primary coffeeâexport hub and the origin of the term âmochaâ.
Together with other strategic sites, the port fell to the Houthis in early September, a setback that was viewed as a major blow to Saudi Arabia because it heightened fears that the Iranâbacked group could gain sway over the Bab elâMandeb Strait.
Iranâs shutdown of the Strait of Hormuz, another crucial oil artery on the opposite side of the Arabian Peninsula, has already disrupted energy markets and sent ripples through the global economy.
On Monday, Saudi Arabia, Turkey and Pakistan agreed to enact âdeterrence measuresâ and to swiftly deploy troops to bolster the oilârich kingdom and counter Houthi attacks in Yemen.
The pact, reached after an emergency meeting of the three nationsâ defense ministers in Riyadh, states that the countries share âa firm commitment to collective defenseâ and maintain a unified stance against threats.
Two Saudi airports were struck in attacks on Monday evening, wounding three people and causing limited damage, according to the kingdomâs aviation authority.
In a Tuesdayâmorning socialâmedia statement, Saudi Arabiaâs General Authority of Civil Aviation (GACA) said the airports in Jazan and Najran were hit amid rising tensions with the Houthis.
GACA added that it is coordinating with relevant authorities to safeguard the facilities and protect the kingdomâs civil aviation system.
Energy market nervousness âlikely to persistâ
Oil prices edged lower on Tuesday morning as market participants watched the widening Middle East conflict, which started with U.S. and Israeli strikes on Iran in late February.
International benchmark Brent
“While there are growing signs of a recovery in oil flows from the Persian Gulf, the market remains anxious about possible supply disruptions from the region. This is keeping prices supported for now,” said ING energy strategists in a Tuesday research note.
“Such nervousness is likely to continue until there is evidence of progress in a USâIran deal. Meanwhile, the risk of further escalation remains very real,” they added.

Russia plague: What we know about the suspected case reportedly linked to a lab workerâs death
According to local media reports, as many as 189 people have also been placed under medical observation in Irkutsk in eastern Russia.
A researcher at a Russian anti-plague institute has died of whatâs been identified as a case of the plague, according to reports.
Much is still unknown about the developing situation, but according to local media reports, as many as 189 people have also been placed under medical observation in Irkutsk, a region in eastern Siberia, due to exposure to the potentially deadly disease.
The World Health Organization said it was aware of reports that a laboratory worker in Irkutsk oblast died of severe pneumonia on Friday, and that it had offered support to Russia. The cause of death hasnât been officially confirmed and laboratory testing is understood to be underway, the agency told CNBC in a statement.
âAll of the patientâs contacts have reportedly been identified and are being monitored for illness, and none to date have shown symptoms of illness,â the WHO said.
What is the plague and how does it spread?
Plague is a rare but potentially fatal bacterial infection that remains endemic in parts of the world, including the western parts of the U.S., but can be treated with antibiotics if identified quickly. Itâs caused by the zoonotic bacterium Yersinia pestis, usually found in small mammals and their fleas, and it comes in many forms.
Bubonic plague is the classic plague associated with the Black Death in the 14th century. Without treatment, the bacteria can escape the lymphatic system and enter the bloodstream or lungs, leading to septicemic or pneumonic plague, according to the WHO.
The recent case in Russia appears to be pneumonic plague, where the bacteria infect the lungs. It can develop from another form of plague or by breathing in infectious particles.
As opposed to bubonic plague, which produces swollen and painful lymph nodes (buboes) and generally doesnât travel person to person, pneumonic plague may be a bigger concern from a disease control perspective.
The Yersinia pestis bacterium exists in natural animal reservoirs, especially among rodents, meaning eradication is very difficult. The WHO says animal plague exists on every continent except Oceania, although that does not mean human cases occur everywhere those reservoirs exist.
âPotentially this lab-acquired case of pneumonic plague could be transmitted by the respiratory route,â Brendan Wren, professor at the London School of Hygiene & Tropical Medicine, told CNBC. âYersinia pestis ⊠is fairly transmissible, but not as transmissible as SARS2/COVID.â
Whatâs happening with the suspected case in Russia?
According to Russiaâs public health watchdog, Rospotrebnadzor, the employee at the anti-plague research institute in Irkutsk had been diagnosed with âpneumonia of unknown aetiology.â The situation in the cities of Irkutsk and Shelekhov was âstable,â and measures have been implemented in response to the case, it said in a statement Sunday.
Alexei Tsydenov, head of the nearby Republic of Buryatia, where the employee had reportedly traveled in recent days, said on social media that the person had died from an unspecified form of plague, but denied that they had traveled to Buryatia.
CNBC has not been able to independently verify the reports. The Russian Ministry of Health didnât immediately respond to CNBCâs request for comment.
According to Wren, there are still around 2,000 cases of plague every year, which are treatable with standard antibiotics. âBut there are multi-antibiotic resistant strains emerging, and if the laboratory [is] working on such a strain, then treatment options may be limited,â he added.
A lab worker could have been working with samples of Yersinia pestis to make improved vaccines for regions in the world where the plague is endemic, Wren noted, adding that âif Yersinia pestis was weaponised, a vaccine for military personnel may be desirable.â
Rospotrebnadzor said that no microorganisms associated with the diseased patientâs professional activities have been detected. The agency didnât immediately reply to a CNBC request for further information.
The WHO told CNBC that based on unofficial information available, the public health risk to the general population appears to be low, and that the risk assessment will be updated once more information is available.
