Apple Watch Battery Hacks That’ll Get You More Hours on a Charge
Seven settings you can tweak right now to add at least two more hours of battery life.
Charging my electronics at the end of each day was just as part of my routine as brushing my teeth. I’d set my iPhone and Apple Watch on their chargers, power down my screens and settle in for a night free of tracking and notifications.
That is, until sleep tracking complicated everything. The Apple Watch can record several important health metrics during sleep and look for indicators of sleep apnea, hypertension and even early signs of illness. It’s gotten too good to ignore.
My biggest challenge with this new sleeping arrangement has been battery life. The Apple Watch needs at least seven consecutive nights of sleep tracking to start analyzing the data. And even though the current Series 11Â and last year’s Series 10Â can last through a full day and a night of sleep tracking, they leave me with a dead watch around lunchtime if I don’t recharge.
After too many days of not receiving credit for midday workouts and obsessively watching the battery percentage drop, I began searching for every trick to maximize my Apple Watch’s battery life. And I’m guessing I’m not alone. Here’s what’s helped.
1. Charge as fast as possible
The first thing you can do without sacrificing any features is make sure you’re actually getting full fast charging speeds. The Series 10, Series 11, SE 3Â and Ultra 3 all support superfast charging, but I realized I wasn’t using the right wattage wall adapter.
Apple doesn’t include a charging brick anymore, so if you plug your cable into whatever spare charger that’s lying around your kitchen (like me), you’re probably not charging your watch as quickly as you could. Apple recommends a 20-watt or higher USB-C power adapter, which should charge newer models from empty to full in less than an hour or provide enough juice for a full night of sleep tracking in five minutes — about as long as it takes to brush your teeth.
2. Gain a few more hours with a small trade-off
Extending your battery won’t come without some compromises, but the easiest sacrifice for me is turning off “Wake on Wrist Raise” and “Wake on Crown Rotation” in Settings. On watches with an always-on display, this simply means the screen remains in its dimmer “resting” state until you tap it intentionally, rather than lighting up every time you move your wrist or brush the crown.
It won’t work on older models that lack an always-on display, but if you have a compatible watch, it can easily add 4 extra hours of use. The only caveat is that you won’t see your notifications immediately. You’ll still receive the haptic alert, but you’ll need to tap in to view the notification, rather than simply tilting your wrist to see it appear.Â
To disable it, open the Settings app, go to Display & Brightness and then scroll all the way to the bottom and toggle off both options.
3. Dim the lights
Lower your screen brightness — it’s another small trade-off, but only on a sunny day. The watch comes out of the box with its brightness set around two-thirds of its peak level. The screen’s brightness will automatically adjust based on your environment, but you can force it to stay at the lowest setting. In the Display & Brightness settings, reduce the Brightness level to one bar.Â
Dimming your watch’s display can add one or two extra hours of battery life between charges, depending on where you spend your day and how often the screen wakes. The only times I miss having a bright screen are during outdoor runs in blazing sun. But sacrificing brightness for a longer battery life is by no means a deal-breaker.Â
4. Go for a bare-bones watch face
Switching to a simpler watch face can also help squeeze more life out of the battery. The more pixels your watch has to light up (think photo faces) or the more animation involved (hello, Memojis), the faster your battery drains. The same applies to constantly updating complications, such as the weather or your heart rate.
Apple doesn’t offer a battery-use score for its watch faces the way some Android watches do, but as a general rule of thumb, darker, simpler faces with fewer active elements last the longest. My go-tos are Activity Digital, which displays only my rings, or X-Large, which shows only the numbers.
5. Getting through Day 2 will cost you
A few extra hours of battery life are great, but sometimes even that isn’t enough to get me through the day. My biggest issue is running out of juice when I’m away from home and a charger is nowhere to be found. Even if your weekday routine includes an office charge, weekends are unpredictable, and it’s best to make it to the evening when you’re closer to your charger.
For me, the next-level compromise is turning off the always-on display. You’ll need to raise your wrist to wake the screen, but this feature can add up to 6 hours of battery life, depending on your model.Â
To turn it off, go to Settings, then select Display & Brightness and toggle off Always-On. Note that it also affects workouts, so if you prefer training with your heart rate zones or other stats visible at a glance, this might not be the best option.
6. Turn on low power mode as a last resort
If I really need to squeeze every last drop of battery life, I switch to low power mode once when the watch hits 15%. It’s actually easier to toggle on and off than the always-on display, since it’s accessible in the control panel via the side button. Tap the Battery Percentage button, then tap Low Power Mode.
Low power mode does more than just disable the always-on screen. It also delays notifications (only slightly), turns off auto-start for workouts (so you’ll need to start them manually) and pauses background measurements. Heart rate zone alerts, high/low and irregular rhythm notifications, and loud environment alerts are all disabled, too. However, during a workout, heart rate and pace are still measured.
7. Check the health of your battery
If you’re still experiencing poor battery life after trying all these troubleshooting tricks, it may simply be time to check your battery’s health. Even with the best habits, a worn-down battery can only do so much, and at some point an upgrade or replacement is the only real fix.
Older models tend to show wear sooner, but it’s not guaranteed. Charging patterns and overall use can take a toll on newer models, too. Having Apple replace the battery costs about $99, or you can put that money toward a newer model, like the SE 3, which starts at $249. If you have AppleCare Plus and your battery capacity is below 80%, the repair or replacement (if needed) is included.Â
To check your battery health, go to Settings> Battery, tap Battery Health, then scroll down to Maximum Capacity. Anything around or below 80% can start to cause noticeable issues.
Which Apple Watch model you have also matters for battery life
If you decide upgrading is your best choice, the Apple Watch Ultra line (especially the Ultra 3) offers the longest battery life by far. Apple says 42 hours per charge but I consistently hit closer to 48 hours without disabling features. The Series 11 is rated for up to 24 hours, although I typically get about 30 hours with a full night of sleep tracking and a 40-minute GPS workout.
Apple doesn’t advertise it, but larger-sized models generally last about two hours longer than smaller ones — so the 46mm Series 11 outperforms the 42mm. Models like the SE 3 or the Series 10 and older are rated for 18 hours with the always-on display enabled but I’ve pushed mine past the 22-hour mark.
Whatever mix of tricks you use (or whichever new model you start fresh with), here’s hoping you crack the battery routine and get the full benefit of everything the Apple Watch can do for your health.

Experts sound alarm after researcher puts AI extinction risk above 10%
Former Anthropic researcher Jacob Coxon says leading AI labs are gambling with human lives, while alignment specialists warn the technology could pose more than a 10% extinction risk within the decade.
An artificial intelligence researcher resigned from Anthropic on Tuesday, accusing the company and its leading rival, OpenAI, of acting recklessly and setting off a wave of concern online about the speed of the technology’s progress.
Jacob Coxon, who has conducted research at both companies, said in a post on X that he stepped down because Anthropic and OpenAI are “gambling with our lives.” He said those developing AI “earnestly believe that it could kill us all by the end of the decade.”
“Do not underestimate the power of this technology,” Coxon wrote. “These will soon be superhuman systems that can hack anything, revolutionize any field overnight, and acquire real power and resources.”
Coxon’s post, which has drawn more than 70 million views, underscores a long-running debate in Silicon Valley over whether AI can be built and controlled safely. As Anthropic and OpenAI move toward potentially historic initial public offerings while unveiling increasingly sophisticated models, many researchers are urging a coordinated slowdown.
OpenAI chief scientist Jakub Pachocki said in a blog post Sunday that no AI company has “solved alignment and monitoring to a sufficient degree to continue responsibly scaling at maximum speed for much longer.” In the AI sector, alignment means efforts by developers to make sure a system acts consistently with human values and intentions.
“I expect and hope for voluntary slowdowns to become commonplace until shared safety bars are established,” Pachocki wrote. “And I believe that international coordination on future AI development needs to become a top priority for governments around the world.”
Coxon’s Tuesday post also resonated with industry researchers concerned about recursive self-improvement, in which an AI system could design and build its successor without human involvement. Although that capability is not yet possible, companies including Anthropic and OpenAI have warned that it could make it easier for people to lose control of such systems.
“Neither company is acting responsibly,” Coxon wrote. “They are racing straight to self-improving superintelligence.”
Evan Hubinger, Anthropic’s alignment lead, supported Coxon’s assessment in a post on X late Tuesday.
“Jacob is correct here—we really do earnestly believe AI could kill all humans! I personally think it is >10% within the next decade,” Hubinger wrote. “I believe Anthropic is trying its best, but we do not yet have a plan to solve alignment for superintelligence and are not clearly on track to.”
Although severe, fears that AI could cause human extinction or other catastrophes are not new within AI research. In 2023, prominent researchers and executives, including OpenAI CEO Sam Altman and Anthropic CEO Dario Amodei, signed a statement declaring that “Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war.”
Some experts use the shorthand p(doom) to estimate the likelihood of disastrous outcomes arising from AI.
Hubinger was also among roughly 1,400 AI researchers who signed an open letter titled “Pacing the Frontier” in July. The letter called on the U.S. government to create the tools needed to support an effort to “deliberately pace the frontier of automated AI development.”
Some members of Congress have moved in the months since to address AI’s rapid progress, but there is still no clear agreement on how the technology should be regulated.
In July, Rep. Jay Obernolte, R-Calif., and Rep. Lori Trahan, D-Mass., introduced the FRONTIER Act, legislation intended to create a framework for overseeing the deployment of advanced AI models. Earlier this month, Sen. Bernie Sanders, I-Vt., and Rep. Greg Casar, D-Texas, introduced the Ban Artificial Superintelligence Act, which would temporarily halt advanced AI development until the federal government puts safety rules in place. Both measures have received mixed responses.
“Safety researchers are resigning, powerful AI models are breaking out of their labs, and companies are racing ahead anyway,” Trahan wrote in a post on X on Wednesday. “It’s past time for Congress to get off the sidelines and do its job.”
Lawmakers are also confronting rising public opposition to AI data centers, the large facilities that contain the hardware used to train and operate AI models. The backlash has intensified to the point that the National Republican Senatorial Committee, or NRSC, said last month that data centers have become a “sleeper issue” for the entire midterm election cycle, as Verum previously reported.
Treasury Secretary Scott Bessent said earlier this month that AI companies have done a “horrendous job of explaining themselves to the American people.”
“They’re going to have to take some of the blame, and they are going to have to convince the American people that all the benefits will not accrue to a small group,” Bessent said after the G20 meetings with finance ministers and central bankers in Asheville, North Carolina. “That’s what they hear from me.”

Hit TV show ‘South Park’ becomes ‘South America’ in apparent reference to Trump’s geographic name changes
The animated series ‘South Park’ is rebranding to ‘South America’ in a satirical jab at President Trump’s recent geographic renaming efforts, including changes to Lake Ontario and the Gulf of Mexico.
Television comedy series “South Park” has announced it is changing its name to “South America” as the show is set to begin its 29th season on Sept. 16. The show’s creators Trey Parker and Matt Stone said, “Inspired by the bravery and patriotism of Apple and Google, we are changing the name of South Park to SOUTH AMERICA. We especially want to thank our parent company Paramount — a Skydance Capitulation.” Parker and Stone’s statement comes after U.S. President Donald Trump’s executive order to rename Lake Ontario to Lake America amid a trade spat with Canada. Canadian officials said they will not recognize the new name. Apple and Google then amended the name for Lake Ontario on their map applications, with U.S. users seeing “Lake America,” while Canadian users saw “Lake Ontario.” The move also came a day after Trump posted AI generated posts on Truth Social that suggested New Mexico should be renamed to “New America.” Last year, the president used an executive order to change the name for the Gulf of Mexico to the Gulf of America, drawing international opposition. “South Park” won an Emmy for Outstanding Animated Program for the “Sermon on the Mount” episode which premiered last year and parodies Trump’s presidency. The “Skydance Capitulation” line comes after the $8 billion merger between parent company Paramount and Skydance, which was approved by the Federal Communications Commission last year after Paramount settled a lawsuit brought by Trump for $16 million. Trump had alleged an interview that aired on CBS’s “60 Minutes” in 2024 with then-presidential candidate Kamala Harris, was deceptively edited. Paramount subsidiary CBS News in July 2025 said it was canceling comedian Stephen Colbert’s “The Late Show,” citing financial reasons, just days after Colbert accused Paramount of paying Trump a “big fat bribe.” The final episode of the show aired in May. Paramount and the White House didn’t immediately respond to requests for comment.

Trump says he has no regrets about starting the Iran war as U.S. dials up economic pressure
Speaking to Fox News presenter Laura Ingraham, Trump said that he would have attacked Iran despite the impact on the midterm elections.
U.S. President Donald Trump said he has no regrets about starting the Iran war and added that “If I had it to do again, I would do exactly what I did.”
Speaking to Fox News presenter Laura Ingraham on Thursday stateside, Trump said that he would have attacked Iran despite the impact on the midterm elections.
“If we hadn’t done Iran, you would be cruising to midterms victory right now,” Ingraham told Trump, to which Trump replied “supposing we were cruising, and all of a sudden Iran has a nuclear weapon. They would use it.”
He added that if Iran had a nuclear weapon, the Islamic Republic would “wipe out” Israel and the Middle East, and start hitting U.S. cities.
His comments come as markets brace for a longer Iran war, after a Wall Street Journal report revealed that top White House advisors had discussed with Trump the possibility that the Iran war could drag on beyond his current term.
Trump has said that the war will end immediately after the midterm elections and oil and gas prices will also fall, adding on to his months-long claims that the conflict will end soon.
In separate comments to NewsNation on Thursday, Trump denied reports that there was any damage to U.S. assets, after Iran claimed it had hit multiple U.S. fighter aircraft at a base in Jordan.
“No damage. No nothing,” Trump said, when asked if there was any truth to the reports.
Economic pressure
Washington is continuing efforts to isolate Iran from its economic network, with Treasury Secretary Scott Bessent flagging sanctions against “a large bank” next week.
“We’re going to do it on Monday because we want to honor the memory of our fallen citizens on 9/11. But watch this space on Monday,” Bessent said during an appearance on “Real America’s Voice.”
Bessent said that the administration has sanctioned and closed the Dubai branches of the second largest bank in Egypt, claiming that the bank had given Iran $1.8 billion dollars. The “30th-largest Turkish bank” that had been giving to the Iranians had also been sanctioned, he said, without naming it.
The U.S. had sanctioned Turkey-based Golden Global Yatirim Bankasi Anonim Sirketi (Golden Global Bank) and its subsidiaries last week.
Trump, in the NewsNation interview, was also asked how Iran could continue holding out under the current economic pressure.
“I don’t know that they’re gonna be able to hold out,” Trump said. “But it’ll get settled after the elections. Or maybe sooner. But it’ll get settled right after the election.”
Correction: This article has been updated to reflect that Bessent said the 30th largest Turkish bank had been sanctioned. An earlier version misstated the bank’s ranking.
