Galaxy S23 Battery Life: Does It Last Longer Than the Galaxy S22?
Samsung’s new phone packs a bigger battery. Let’s see how it compares to its predecessor.
This story is part of Samsung Event, CNET’s collection of news, tips and advice around Samsung’s most popular products.
My biggest complaint about last year’s Galaxy S22 was that its battery didn’t last long enough on a single charge. Luckily, Samsung has addressed that shortcoming with the recently launched Galaxy S23, which includes a larger battery and a more power efficient processor.
The Galaxy S23 doesn’t offer record-breaking battery life, but it’s enough of an improvement to make me feel comfortable using it on a busy day without carrying a charger. That’s more than I could say for the Galaxy S22, which left me with battery anxiety on long days spent away from a power outlet.Â
Petite Android phones like the Galaxy S23 and Galaxy S22 can be hard to come by, which is why I’m glad Samsung made this fix to its 6.1-inch flagship phone.Â
Galaxy S23’s bigger battery makes a difference


The Galaxy S23 has a bigger battery than its predecessor.
Lisa Eadicicco/CNETSamsung increased the Galaxy S23’s battery capacity by 200 mAh compared to the Galaxy S22. The new phone has a 3,900-mAh battery, while last year’s device has a 3,700-mAh capacity. But that’s not the only factor influencing battery life.Â
The Galaxy S23 family runs on a version of Qualcomm’s Snapdragon 8 Gen 2Â processor that’s been optimized specifically for the Galaxy S23 series. Samsung says this new processor brings better power efficiency, contributing to the phone’s longer battery life.Â
Even after spending a short time with the Galaxy S23, these changes are noticeable. The Galaxy S22’s battery would sometimes dip to the 30s or 40s by roughly 9 p.m. after a long day in the office. I even had to borrow a colleague’s charger once while attending an all-day work event because I was worried I wouldn’t make it to the evening. (I typically had the always-on display turned off and the refresh rate set to standard instead of adaptive).Â
My experience with the Galaxy S23 has fortunately been very different so far. I still had 64% of my battery left by 12:36 a.m. on a recent Sunday when I took the phone off its charger at 10 a.m. that morning. However, it’s important to note that I also wasn’t using my phone very frequently that afternoon. I was spending time with my family for a large chunk of the day, so I mostly kept my phone tucked away in my pocket, only retrieving it to occasionally check my texts or take a photo.Â
But even on a busy day, the Galaxy S23 still had more of its battery left than the Galaxy S22 likely would have. After a day of running benchmarks, taking lots of photos, recording videos and streaming YouTube videos as part of my review testing, I still had 46% of my battery left by 9:45 p.m. That’s not so bad when you consider the Galaxy S22 sometimes had 30% to 40% of its battery left by around 9 p.m. after using the phone heavily throughout the day. I also left the adaptive refresh rate setting turned on most of the time I spent with the Galaxy S23.
To further test the battery, I put each phone through a 45-minute endurance test and a three-hour battery drain test. During the 45-minute test, I continuously streamed videos on YouTube, made a video call, played mobile games and scrolled through social media feeds to see how much of a dent these everyday tasks would make in each phones’ battery. For the three-hour test, I streamed YouTube with the display brightness set to 100% and checked the battery percentage once every hour to see how much it had drained.
Unsurprisingly, the Galaxy S23 beat the Galaxy S22 in both tests, as you can see in the tables below.
Galaxy S23 vs. Galaxy S22 45-minute test
| Galaxy S23 | 91% |
|---|---|
| Galaxy S22 | 89% |
Galaxy S23 vs. Galaxy S22 3-hour test
| 1 hour | 2 hours | 3 hours | |
| Galaxy S23 | 95% | 88% | 81% |
| Galaxy S22 | 91% | 81% | 71% |
It’s important to remember that battery life will always vary depending on how you use your device. Factors like screen brightness and the types of apps you’re using will impact battery life, so your experience may not directly mirror mine. For example, even though I sometimes struggled to get through a whole day using the Galaxy S22, I was able to preserve roughly 60 to 70% of my battery by 9 p.m. with the always-on display turned off on days mostly spent at home.
How to get the most battery life out of your Galaxy S22


The Galaxy S22.
Lisa Eadicicco/CNETIf you own a Galaxy S22 and are struggling with battery life, there are a few steps you can take to maximize your device’s longevity. First, try turning down the screen brightness by pulling down from the top of the display to access your phone’s quick settings menu.Â
You’ll also want to make sure the adaptive brightness setting is disabled to prevent your phone from automatically boosting brightness when needed. While that can be a useful feature under normal circumstances, you might not want the brightness to increase when you’re trying to conserve battery life. Open your Galaxy S22’s settings menu, choose the display option and make sure the switch next to adaptive brightness is toggled off.Â
It’s also a good idea to try turning off the adaptive refresh rate and always-on display settings if you’re trying to extend battery life, which you can toggle in the settings menu.
Samsung devices have a power savings mode that disables certain settings to make the battery last longer. Open the settings menu, select the battery and device care option and then tap battery to access it. From this battery menu, you can also limit battery usage for apps that you don’t use very often.
These tips will work on the Galaxy S23 too, which also has a light performance mode to prioritize battery life and cooling efficiency over high performance. To turn this on, open the Galaxy S23’s settings menu, tap battery and device care, and select battery. Scroll down to the bottom of the screen and choose the more battery settings option. From there, you should see a field called performance profile, which you can tap to switch between standard and light. (During my time with the Galaxy S23, I had it set to standard).Â
If that’s not enough, you can try purchasing a portable charger or power bank to power up your device on the go.Â
With its new $700 price, the Galaxy S22 is a tempting choice alongside the $800 Galaxy S23. Just remember you’ll be sacrificing some battery life to get that cheaper price.Â

Nvidia CEO Jensen Huang emerges as Trump’s top ally in AI safety debate
Jensen Huang’s position as the leader of the world’s most valuable company, has earned him Trump’s ear on the most important topics in AI.
With the debate about regulating artificial intelligence raging in Washington this week, President Donald Trump picked up the phone to call his top ally on the subject: Nvidia CEO Jensen Huang.
âThe robots are not going to be taking over the world,â Trump told Huang, whoâd put the president on speaker while on stage at the All-In Summit in Los Angeles on Monday. Trump repeated a point heâd made on social media: that mounting AI and data center concerns are a âhoax.â
While other tech leaders like Meta CEO Mark Zuckerberg and Amazon founder Jeff Bezos have cozied up to Trump during his second term, experts told CNBC that Huang is exercising outsized influence in the White House. Heâs slated to attend Trumpâs high-profile state dinner for Chinese President Xi Jinping next week, according to a person familiar with the matter who asked not to be named due to confidentiality.
Nvidia has been powering the AI boom since before the launch of ChatGPT in late 2022, supplying the graphics processing units used by OpenAI, Anthropic and others to train their models and run large workloads. Revenue surged to $215 billion in the latest fiscal year, up from $17 billion in 2021.
Huangâs position as the leader of the worldâs most valuable company and the chipmaker at the heart of the AI boom has earned him the presidentâs ear on the most important AI topics.
âTrump just likes winners, and Jensenâs very good at speaking his language,â Samuel Hammond, director of AI policy at the think tank Foundation for American Innovation, said in an interview.
An Nvidia spokesperson declined to comment, and White House representatives didnât respond to a request for comment.
Whether joining Trump for a candlelit dinner at his Mar-a-Lago club in Florida, or closing a keynote by thanking guests for âmaking America great again,â Huang has learned how to appeal to the president. Trump and Huang have appeared together at least six times in public since the start of the second term, including trips to Saudi Arabia and the U.K., and a recent trip to China via Air Force One.
Huang is pushing for U.S. AI to move faster while some of Nvidiaâs most important customers â namely OpenAI and Anthropic â are ramping up pressure on governments to regulate the technology as fears spread about its potential dangers.
An Anthropic researcher, Jacob Coxon, who previously worked at OpenAI, said he quit his job earlier this month because he feared top AI labs are âgambling with our lives.â Coxonâs resignation set off a firestorm on social media, prompting calls for increased oversight from more than 20 members of Congress.
Concerns were already swirling after OpenAI disclosed a significant security incident in July, when two of its models escaped containment, accessed the open internet, and breached the online AI repository Hugging Face to get a better score on a benchmark test.
Anthropic CEO Dario Amodei cited that episode in a bombshell essay a week ago, urging AI developers to slow how quickly they improve their most advanced AI models. Amodei encouraged companies to cooperate directly with the U.S. government, and reiterated his desire for âwell-considered regulation of AI.â
Amodeiâs âpacingâ proposal was endorsed by other industry leaders, including OpenAI CEO Sam Altman, SpaceX CEO Elon Musk and Google DeepMind Chair Demis Hassabis, who agreed on the need for a slowdown and additional oversight.
âDid no harmâ
Huang took a different position.
In public appearances over the past week, the Nvidia CEO brushed off concerns about AIâs risks. He said that predictions of doom arenât grounded in science, and that model developers are responsible for securing their products before releasing them.
The solution to safety concerns, Huang said in Scotland on Thursday, is âgood old-fashioned engineering.â
âThere were incidents, and those incidents, thankfully, did no harm,â Huang said.
Huangâs position is largely shared publicly by David Sacks, a venture capitalist who previously served as Trumpâs AI and crypto czar. Sacks co-hosts the âAll-Inâ Podcast, which produced Mondayâs event that featured the Trump-Huang call.
âThe only control or âguardrailsâ that AI needs is a STRONG AND SMART (High IQ!) PRESIDENT, and the U.S.A. has that, in spades!,â Trump wrote in a post on Truth Social on the same day as the summit.
Before the recent uproar over safety, Nvidia focused its Washington outreach on export controls.
Last year, Nvidia was pushing to sell its AI chips to restricted countries, including China, drawing sharp criticism from U.S. lawmakers.
Some members of Congress, including Sens. Elizabeth Warren, D-Mass., and Josh Hawley, R-Mo., have cautioned that selling Nvidia hardware to China could threaten U.S. national security and narrow Americaâs lead in AI.
In December, Huangâs strategy paid off. Trump announced that Nvidia was granted permission to ship its H200 chip to Chinese customers, and that the U.S. would collect a 25% fee in exchange.
The H200 announcement drew intense pushback from both sides of the aisle. Huang declined an invitation from Warren to testify before the Senate Banking Committee in June. The following month, a top U.S. trade official confirmed that H200 sales to China were underway.
Profit motive
Nvidia and Huang argued that banning Nvidia exports to China would be against American interests, in part because such a move would spur the worldâs second-largest economy and computing market to develop its own cutting-edge AI chips. The H200 is no longer Nvidiaâs most powerful chip, as it has shipped two generations of its newer Blackwell processors in the U.S.
But Nvidiaâs fate wasnât entirely up to U.S. lawmakers, as Chinaâs regulators mostly blocked imports of the H200 chips.
Nvidiaâs clear profit motive leads some experts to say it takes the concerns expressed by model developers more seriously than those of the chipmaker, because the labs are the ones responsible for the actual AI technology.
âNvidia is the most aggressive in terms of, letâs just make money,â said Andrew Yoon, a researcher at CivAI, a nonprofit warning about the dangers of AI. âAt every turn, they are really trying to just make sure whatever happens is good for Nvidiaâs bottom line.â
Nvidiaâs ambitions in China will loom large during the state dinner on Thursday, when Trump, Huang and Xi will all be in the same room. The White House is also planning a meeting with major AI executives to coincide with the event, according to CNN. Other industry executives, including Altman, are expected to attend.
But Huangâs presence carries extra weight. During a House hearing on Monday, Treasury Secretary Scott Bessent was asked if Trump understands the threat AI presents.
âI would just say the president is completely aligned with Jensen Huang, the CEO of Nvidia,â Bessent said.

Iranian President Pezeshkian to travel to New York for UN summit as Trump threatens consequences of no agreement
Iranian President Masoud Pezeshkian is set to attend the UN General Assembly in New York as diplomatic hopes rise, even as U.S. President Donald Trump warns of severe consequences if no deal is reached.
President Masoud Pezeshkian is set to lead an Iranian delegation at the United Nations General Assembly in New York on Tuesday, as fresh optimism emerges for a diplomatic resolution to the Middle East conflict.
According to the semi-official Tasnim news agency, Pezeshkian will deliver a speech before the assembly, outlining Iranâs stance on âinternational developments,â with special attention to its conflict with the U.S. and Israel.
He is also expected to meet with several world leaders on the margins of the gathering, which runs from Sept. 22 to 26, and Sept. 28.
The Iranian delegationâs participation at the UN has sparked renewed optimism for a diplomatic path out of the war, boosting market sentiment on Monday â equities climbed, oil prices softened, and global bond yields dropped sharply.
However, U.S. President Donald Trump â who has indicated willingness to meet Pezeshkian during the assembly â has warned that Iranâs economy would be devastated or its leadership eliminated if Tehran fails to reach an agreement.
Speaking to Fox News on Sunday, Trump said the only choices available were âwiping Iran out,â or allowing its economy to ârot,â unless a deal is reached.
Meanwhile, Iranâs military said its intelligence pointed to a new, large-scale strike being orchestrated by the U.S. and its allies, cautioning of âpainfulâ retaliation throughout the Middle East. Any regional nations supporting such an attack would be considered participants in the conflict, it added.
âIf the U.S. commits any error against the Islamic Republic of Iran, all its positions and interests in the region will face sustained, effective and painful strikes,â the Khatam al-Anbia Central Headquarters of Iran stated, per Tasnim.
Houthi-Saudi conflict complicates diplomacy hopes
The U.S. State Department issued a security alert over the weekend, warning of potential unforeseen escalation in the Middle East and urging Americans to stay vigilant and prepare for possible flight cancellations and airspace closures.
The alerts followed claims by Iran-backed Houthi militants of missile and drone strikes on Riyadh on Saturday, which triggered the first air-raid warning in the Saudi capital since hostilities intensified in July.
Saudi officials reported that a ballistic missile was intercepted and destroyed, with no casualties or damage. The Houthis also tried to strike civilians and infrastructure across multiple areas of the kingdom, according to Saudi-led coalition spokesperson Major-General Turki al-Maliki, who posted on X on Saturday that those attempts were repelled by the countryâs air defenses.
Despite widening hostilities, oil prices have retreated in recent days as traders anticipate a recovery in energy shipments from oil-rich Saudi Arabia.
Oil prices will stay elevated despite U.S. advances in moving oil through the Strait of Hormuz, a team of analysts at Eurasia Group noted in a Saturday report. Any increase in oil flows would be insufficient to close the overall market deficit, they said, projecting Brent prices to trade in a higher range of $90-110 per barrel for the remainder of this year.
âIranâs leadership will stick with resistance, even as they quarrel internally,â the consultancy firm stated, noting that Tehran aims to use military proxies and tanker attacks to maintain a chokehold on shipping flows and pressure Washington into concessions.
Tehran has maintained it will not reopen the Strait of Hormuz until Washington honors its commitments under the June memorandum, which called for lifting the naval blockade of Iranian ports, easing sanctions, unfreezing Iranian assets, and ending U.S. military threats.
Iranian parliament speaker Mohammad Bagher Ghalibaf said Sunday that Iran must continue both fighting and negotiating to push back its adversaries, and only pursue diplomacy when it holds the advantage on the battlefield.

Oil prices drop below $100 per barrel as Trump shows willingness to engage with Iran
Oil prices fell below $100 per barrel as Trump expressed openness to diplomacy with Iran, amid ongoing regional tensions and attacks.
On Monday, crude oil prices saw a sharp decline, trading below $100 per barrel, after President Donald Trump reportedly opted against bombing Yemen for the time being and signaled openness to diplomacy with Iran. U.S. West Texas Intermediate futures decreased by 5.4% to $94.85 per barrel by 10:48 a.m. ET. Brent crude, the international benchmark, experienced a fall of 4.1% to $99.61 per barrel. Oil prices have declined for four consecutive sessions as the market retreats from the recent rally. Trump informed Fox News that he might be willing to meet with Iranian President Masoud Pezeshkian during this week’s UN General Assembly. Additionally, the U.S. president has chosen not to bomb Iran-allied Houthi militants at present, despite appeals from Saudi Arabia, according to Trump administration officials who spoke to The New York Times. In the meantime, crude exports from the Middle East have remained resilient following Saudi Arabia’s shutdown of its crucial East-West pipeline due to attacks, as stated by JPMorgan analysts in a note dated Sept. 18. Total oil flows averaged 17 million barrels per day over the past 10 days, which is 6 million bpd below the 2025 average, they reported. Exports through the Strait of Hormuz have steadily increased, with flows from the broader Middle East reaching approximately 80% of pre-war levels, according to Ryan McKay, director of commodity strategy at TD Securities. McKay stated in a Monday note that without a major escalation, Iran may have lost significant leverage in the Strait. However, the security situation in the region continues to be volatile and susceptible to sudden escalation. McKay noted that the oil market is struggling with multiple near-term drivers that are engaged in a tug of war for prices. The Houthis announced that they launched missiles at Riyadh, the Saudi capital, and targeted Aramco facilities at the Yanbu crude export terminal on the Red Sea over the weekend. At least two tankers have been attacked while transiting the Strait of Hormuz in the past day, based on incident reports from the United Kingdom Maritime Trade Operations Centre. Trump also told Fox that he is in a ‘deciding mode’ and that ‘very big things’ will happen soon concerning the Iran war. He described the options as ‘wiping Iran out, letting them rot economically, or making a deal,’ as reported by Fox. Meanwhile, Iran’s Revolutionary Guard warned that it will expand the ‘geography of the conflict’ if the U.S. launches renewed strikes against the Islamic Republic, according to the state media outlet Tasnim.
