Not Everyone Should Upgrade to Samsung’s Galaxy S23 Just Yet
You should consider several factors before switching. Compare these older Samsung phones to help guide your decision.
This story is part of Samsung Event, CNET’s collection of news, tips and advice around Samsung’s most popular products.
Samsung’s Galaxy S23 just launched in February, so you may be wondering: Is it worth the upgrade? Truth is, there isn’t one answer that can be applied to everyone. The age and condition of your current phone, your budget and whether your device will support new versions of Android should all factor into your decision.Â
The Galaxy S23, which starts at $800, has a 6.1-inch screen and a 50-megapixel main camera, just like the Galaxy S22. But the S23 has a larger battery, a new processor and slightly updated camera algorithms that improve the way photos are processed. While these changes are appreciated, the Galaxy S23 is generally a minor improvement over the Galaxy S22. The upgrade is worth it if you’re looking to replace a phone you’ve had for several years, ideally one that’s more than two years old. Even the Galaxy S21, which launched in 2021, likely still has enough life left to make it through another year.Â
Buying decisions will always vary depending on your needs and budget. But if you’re a current Samsung user considering making the jump, here’s what to know about how the Galaxy S23 compares to older devices.
Galaxy S23 vs. Galaxy S22


The Samsung Galaxy S22.
Lisa Eadicicco/CNETWith the Galaxy S23, Samsung addressed my biggest concern about the Galaxy S22: its short battery life. The new phone has a larger battery (3,900 mAh compared to 3,700), which has made a difference in my testing.
Otherwise, compared to the Galaxy S22, you’re getting a new Qualcomm Snapdragon 8 Gen 2 processor that’s been optimized for the new Galaxy lineup specifically, while the Galaxy S22 runs on last year’s Snapdragon 8 Gen 1 chip. Performance is faster, especially when exporting video. But you probably won’t notice much of a jump in everyday use, since most modern processors are well-equipped to handle gaming, multitasking and other run-of-the-mill tasks.
The Galaxy S23’s cameras are largely the same as the Galaxy S22’s, except the algorithms have been updated to improve processing in low light conditions. The selfie camera also has a slightly higher resolution (12 megapixels versus 10), although I didn’t notice much of a difference. There’s nothing about the Galaxy S23’s camera that feels hugely different from the previous generation, although I did notice that low-light portraits looked better.
The phone launches with Android 13 and Samsung’s One UI 5.1 software, both of which are available for the Galaxy S22 series.Â
The bottom line: Don’t upgrade to the Galaxy S23 if you have a Galaxy S22. The changes aren’t noticeable enough to warrant an upgrade. Battery life is the only meaningful change you’ll notice between the two phones, but I’d only recommend upgrading if you can get the S23 for free through a trade-in deal.Â
Galaxy S23 vs. Galaxy S21


Samsung’s Galaxy S21.
Sarah Tew/CNETThe differences between the Galaxy S23 and Galaxy S21 are more noticeable, but you can probably hold onto your S21 for another year before upgrading.Â
The Galaxy S23 has a noticeably improved camera since it inherits the 50-megapixel sensor that debuted on the Galaxy S22. As I wrote in my review, the Galaxy S22’s cameras offer better color, contrast and low-light performance compared to the Galaxy S21.Â
The Galaxy S21 also runs on a processor that’s now two years old, compared to the brand-new chip in the Galaxy S23. That said, if you’re just using your phone for simple tasks like video calls, playing games and checking social media, the older Snapdragon 888 chip is probably holding up just fine.Â
The bottom line: If your Galaxy S21 still feels fast and the battery life is satisfactory, you can wait another year before upgrading. Samsung supports three generations of Android operating system updates for the Galaxy S21, meaning it will get new platform-wide software updates until 2024.Â
Galaxy S23 vs. Galaxy S20


Samsung’s Galaxy S20.
Angela Lang/CNETWhether you should upgrade from the Galaxy S20 isn’t as straightforward of an answer. There’s enough to gain that would justify making the jump, but the Galaxy S20 also still has plenty to offer.
By upgrading, you’ll get a faster chip, an improved camera with significantly better low-light performance and a fresh design. Since the Galaxy S20 launched in 2020 with Android 10, it’ll no longer be eligible for new Android OS updates moving forward.Â
Samsung committed to providing three generations of updates for the Galaxy S20 lineup, making Android 13 the last one. That means you’ll have to upgrade to get future versions of Android and the new features that come along with these updates. The company does, however, still provide monthly security updates for the Galaxy S20.Â
At the same time, the Galaxy S20 is still a very capable phone. Even though you won’t get the option to shoot photos at a 50-megapixel resolution like on the Galaxy S23, you’ll still get a triple-camera setup on the Galaxy S20. The Galaxy S20 also has a 30x digital zoom like the Galaxy S23, so you won’t miss out on getting close-up shots.
But keep in mind that the Galaxy S20 has a larger battery and a slightly bigger screen than the Galaxy S23. And most importantly, the Galaxy S20 has a microSD card slot for adding more storage, which the Galaxy S23 does not.Â
The bottom line: The updates in the Galaxy S23 will feel significant enough to justify the upgrade, but you also don’t need to if you’re happy with your Galaxy S20. Hang onto the S20 if you’re happy with its performance, battery life and if you value keeping that microSD card slot over having a better camera. Just remember you won’t get the next version of Android.Â
Galaxy S23 vs. Galaxy S10


The Samsung Galaxy S10 lineup.
Angela Lang/CNETGalaxy S10 owners: it’s time to upgrade. Not only will the camera and processor feel like a huge step up, but you’ll get 5G and the latest version Android.Â
If you purchased the Galaxy S10 at launch back in 2019, the processor and battery are now four years old. That means your phone may be starting to feel sluggish, and the battery probably struggles to get through a day. The Galaxy S10’s battery is also smaller than the Galaxy S23’s (3,400 mAh capacity versus 3,900) and the S23’s processor is more power efficient — so the battery gains should be meaningful. Your Galaxy S10 also doesn’t support 5G, unless you splurged on the 6.7-inch Galaxy S10 5G, which started at $1,300 when it launched.
But more importantly, the Galaxy S10 no longer receives Android version updates. Like the Galaxy S20, the Galaxy S10 was eligible for three generations of new Android releases. That would make last year’s Android 12 update the last one since the Galaxy S10 launched with Android 9. (You will, however, still get quarterly security updates if you have the regular Galaxy S10, S10 Plus, S10E or S10 5G.)
While software support and battery life are among the biggest reasons to upgrade, you’ll also get a much better camera on the Galaxy S23. Samsung’s camera has come a long way over the last four years, now offering a higher resolution main sensor (50 megapixels versus 12 megapixels on the Galaxy S10), enhanced performance in low light and a closer digital zoom (up to 30x on the Galaxy S23 compared to 10x on the Galaxy S10).Â
One thing to keep in mind, however, is that you’ll lose the beloved microSD card slot by upgrading to the Galaxy S23. So be sure to pick a storage capacity that makes sense for your needs since you won’t be able to expand it.Â
The bottom line: Yes, if you have a Galaxy S10 it’s worth upgrading to the Galaxy S23. You’ll get 5G support, access to new versions of Android, longer battery life, a faster new processor and a much-improved camera. But be prepared to say goodbye to the microSD card slot.Â
Galaxy S23 vs. Galaxy S9


The Samsung Galaxy S9.
James Martin/CNETThere are many reasons to upgrade from the Galaxy S9Â — so many, in fact, it’s hard to know where to start. All of the points mentioned above for the Galaxy S10 also apply to the Galaxy S9. Samsung’s five-year-old phone lacks 5G, and its processor and battery have likely started to show their age. You’ll also no longer receive Android version updates.Â
But there are plenty of other benefits to be had from upgrading. The camera is among the biggest changes; the Galaxy S9 only has one rear 12-megapixel camera, and the Galaxy S9 Plus has an additional 12-megapixel telephoto camera. The Galaxy S23 has a higher resolution 50-megapixel main camera, along with a 10-megapixel telephoto camera and a 12-megapixel ultrawide lens for capturing a wider field of view. The Galaxy S23’s selfie camera also has a higher resolution (12 megapixels versus the S9’s 8), along with other improvements like better low-light capture.Â
If you have the standard 5.8-inch Galaxy S9, you’ll also get a larger screen since the Galaxy S23 has a 6.1-inch display. The Galaxy S23 also has twice the storage in the base model compared to the Galaxy S9, but there’s no microSD card slot in Samsung’s new phone for adding more storage.Â
The bottom line:Â There are a bunch of reasons to upgrade if you have a Galaxy S9. You’ll get a significantly improved camera with multiple lenses, much faster performance, longer battery life, new versions of Android and 5G support.Â
Overall, it’s worth upgrading if you have a phone that’s more than two years old. Galaxy S20 owners can probably get another year out of their device if it’s in good condition, but the Galaxy S23 also offers enough improvements to justify the upgrade. If you have a Galaxy S10 or earlier, the answer to whether you should upgrade is a resounding yes.Â

OpenAI chief Sam Altman outlines why the AI sector is urging a slowdown: risk of losing control
Sam Altman and Dario Amodei call for a measured pace in AI development, proposing safety frameworks and international coordination to avoid losing control, while U.S. and Chinese tensions underscore the urgency.
OpenAI’s Sam Altman offered the most thorough remarks to date on potential AI safety frameworks, following his alignment with Anthropic’s Dario Amodei and Elon Musk in urging a temporary slowdown of the sector. Tensions surrounding AI safety have surged after an Anthropic researcher resigned last week, claiming that developers feared the technology could “cause humanity’s demise by the end of the decade,” a warning that spurred similar alarm among OpenAI staff and other lab members. The leaders of major AI firms have recently shown uncommon agreement, as Altman and Musk jointly endorsed Amodei’s essay calling for a measured pace in advancing the most powerful AI models. AI‑related stock prices fell on Monday as investors reacted to the statements, while U.S. President Donald Trump rejected the CEOs’ caution on Sunday, arguing that a slowdown would hinder America’s dominance in AI compared with China. Sam Altman outlines two potential disastrous outcomes for AI development. Altman stated in a late‑night X post that a federal framework establishing uniform safety standards for frontier AI is welcome, emphasizing that “no level of American competitive pressure can excuse reckless behavior.” He warned that AI advancement might lead to loss of control over future outcomes and could concentrate excessive power in the hands of a single individual or corporation. At the same time, Washington legislators are rushing to respond to demands for regulatory safeguards. The developments occur as Anthropic and OpenAI prepare for what could be historic initial public offerings, with Altman stating in a Fortune interview on Saturday that the companies will not pursue an IPO in 2026. Amodei’s three‑step plan. A primary safety concern involves models gaining the capacity to enhance their own performance, a process called recursive self‑improvement (RSI). He noted that since early summer AI has been progressing rapidly, largely because AI systems are now capable of creating the next generation of AI themselves. He warned that without oversight, the technology could outpace our capacity to comprehend and control it, making careful, possibly restrained, development essential. He outlined a three‑step approach designed to slow development while preserving commercial benefits and maintaining the United States’ competitive edge in AI. The plan calls for every frontier AI company to provide external evaluators with access comparable to that of employees — a commitment Anthropic has already made — and urges all such labs to adopt shared safety standards, curb uncontrolled AI acceleration, and coordinate globally. On Saturday, Altman posted on X that he concurred with Amodei’s call for AI firms to “pace the frontier,” adding that adopting independent evaluators with employee‑level access is a worthwhile step and that his company will follow suit. Altman said in a Monday post that consistent regulations to manage frontier risk — such as independent auditors — are valuable, but clarified that “pacing” does not equate to halting progress, which remains swift and ongoing. He concluded that the costs of pacing are justified, asserting that no level of American competitive pressure can excuse reckless actions that let capabilities outpace alignment and monitoring. He noted that governmental assistance will be needed for international coordination, but emphasized that the industry should first act independently. Coordinating AI safety measures and a sector‑wide slowdown with Chinese AI developers will present significant hurdles. The United States and China continue a rivalry for AI supremacy, with tensions rising as Chinese models become increasingly sophisticated and widely adopted. He added that the toughest aspect of his proposal is the possibility that rival nations may decline to adopt similar measures. He noted that the long‑term goal would be collaborative effort to impose a speed limit on AI progress, according to an interview with CBS News’ “Sunday Morning.” He acknowledged that achieving such a limit would be challenging due to strong incentives to get ahead and the military advantages involved, admitting uncertainty about feasibility but urging an attempt. The essay has attracted criticism in China, with state‑owned Global Times stating on Monday that “Amodei’s proposals aim to cast China’s legitimate AI development as a threat and exacerbate U.S.–China confrontation.” China’s Foreign Ministry responded on Monday, labeling the CEOs’ remarks as “fearmongering.”

Novo CEO tells CNBC why drugmaker is rebranding, needs to ‘rethink’ obesity strategy
The Danish drugmaker called the changes the beginning of a new chapter for the company, which faces stiff competition from Eli Lilly.
Novo Nordisk
The Danish drugmaker called the changes the beginning of a new chapter, as it has been grappling with stiff competition from chief rival Eli Lilly
In an exclusive interview with CNBC, Novo CEO Mike Doustdar said the rebrand and culture shift are “part of the same package” for the company to evolve its strategy as it tries to win back customers from Lilly.
“I think there’s no secret that over the last four or five years, the external environment and what has happened to Novo Nordisk has really made us reflect how we need to readjust and rethink about the next decade to come and what shifts are needed in our strategic direction,” he told CNBC.
Doustdar said the “work is cut out for us,” adding that Novo needs to improve several aspects – from research and development and manufacturing to sales and marketing – to be able to compete in the obesity drug market.
Shares of Novo have dropped about 15% this year despite the successful launch of the oral version of Wegovy, which surpassed 3 million prescriptions as of June. The company recently scrapped three trials on an experimental cardiovascular drug. That challenge came as it continues to lag in the obesity space with 38.8% market share compared to Lilly’s 60.9% in the second quarter, according to a Lilly earnings presentation citing IQVIA data.
In a release, Novo also announced a broader company rebrand focused around the phrase “Lasting Health Starts Now,” which promotes the idea that patients should make progress toward long-term well-being immediately rather than later. The company said the marketing is a bid to build relevance and trust with the public and other stakeholders, and bring “breakthrough science closer to people’s daily lives.”
When asked whether the rebrand and cultural overhaul were driven by Novo’s recent market share losses in obesity, Doustdar said the changes were less about competitive setbacks and more about adapting to a dramatically different operating environment.
He said the rapid growth of obesity treatments has transformed Novo’s patient base and shifted the market toward a more consumer-oriented model, where patients move on and off therapies more frequently than in traditional diabetes care. As a result, Doustdar said Novo needs to become more focused on meeting patients where they are, while increasing the speed and clarity of its decision-making to keep pace with the evolving market.
“Our operating environment phenomenally changed compared to just 10 years ago,” he told CNBC.
Novo Nordisk will remain the legal name for the company, according to the release. That original name dates back to the 1989 merger of two competing Danish pharmaceutical companies: Novo Terapeutisk Laboratorium and Nordisk Insulinlaboratorium.
The drugmaker said its corporate culture will be based on a new set of four principles that will help it gain advantages in an increasingly competitive market where more of its products have gone direct-to-consumer.
Those tenets are innovating with patients as the primary focus, raising the company’s performance to “create greater value for all stakeholders,” setting clearer priorities and simpler workflows and never compromising on patient safety and ethics.
“When you think about strategy, that’s really the the journey you’re taking and the direction you’re setting the company to go forward with,” Doustdar said. “But you also need behaviors. You need a cultural element that allows your colleagues and yourself to really make sure that a strategy gets executed.”
Despite its challenges, Novo has had one significant tailwind this year in the launch of the oral version of Wegovy. On top of its explosive launch, the pill had a head start over a rival weight loss pill from Lilly called Foundayo.
Doustdar said Novo has maintained “a lion’s share” of the oral market even with competition, noting that physicians find the Wegovy pill to be more effective than Lilly’s, with around 17% of weight loss.

Iran Claims It Shot Down U.S. Advanced Drone Near Hormuz as Middle East Tensions Rise
Iran says it shot down an advanced U.S. drone over the Strait of Hormuz amid rising tensions and stalled diplomacy. President Trump linked the conflict to potential oil control, citing the Venezuela deal and predicting lower gas prices if the war ends.
Iran’s military announced it had shot down a sophisticated American drone above the Strait of Hormuz, marking the latest volley in a cycle of warnings and strikes between Tehran and Washington that shows no sign of easing.
The Islamic Revolutionary Guard Corps stated on Monday that its newly unveiled advanced aerospace defense system intercepted and destroyed an advanced MQ‑1 drone over the Hormuz strait, offering no further details about the drone’s mission. The MQ‑1, built by U.S. defense contractor General Atomics, has historically been flown mainly by the U.S. Air Force and the CIA.
The downing comes after a string of Iranian actions targeting U.S. unmanned naval assets in the Gulf, as the conflict, now in its seventh month, continues with little de‑escalation and diplomatic efforts over the vital waterway remain stalled.
On Sunday, President Donald Trump said the United States could keep pressing its campaign against Iran and seize control of its oil, comparing the situation to the agreement Washington reached with Venezuela earlier this year.
“We’ll ultimately get out (of the war), unless we decide to stay and keep the oil like Venezuela,” Trump remarked at the Irish Open golf championship in Ireland. He added that the revenue the U.S. gains from the Venezuela deal — which gave Washington access to about one‑fifth of Venezuela’s oil reserves — has “paid for the war many times.”
Under the August agreement, Venezuela handed over majority U.S. control of more than 65 billion barrels of oil reserves — more than twice the size of America’s own reserves — in exchange for $209 billion deposited into Venezuela’s state treasury. Secretary of State Marco Rubio said the pact would also attract roughly $100 billion in private investment to help revive the Venezuelan economy.
Trump also said on Sunday that he expects the seven‑month Iran war to conclude this year, perhaps after the November midterm elections, and insisted that gasoline prices would “drop like a rock” once the conflict ends.
He stressed that he would only accept the “right deal,” noting that Tehran has been “calling constantly” for peace talks, a claim Iran has previously rejected.
**Stalled Hormuz talks**
A planned meeting in Oman between Gulf states and Iran to discuss possible arrangements for the Strait of Hormuz — the crucial conduit for global oil and gas shipments — was postponed, Omani Foreign Minister Badr Albusaidi said on X on Sunday, citing the need for “consensus.”
Iranian and Gulf officials had been slated to meet on Monday to sign an accord establishing an Iran‑Oman shipping lane through the Strait of Hormuz, although no direct negotiations between the United States and Iran were underway at that time.
Since the war began in February, the Strait of Hormuz has been under an Iranian‑led naval blockade, later joined by U.S. forces, keeping global energy prices elevated.
A June agreement between Washington and Tehran collapsed over disagreements about the waterway, and a recent surge in attacks by Yemen’s Houthi rebels — an ally of Tehran — has given that group leverage over another key chokepoint, the Bab el‑Mandeb.
Vessels deemed non‑compliant are routinely struck by Iranian forces, while the United States periodically launches strikes on the Iranian coast to challenge the Islamic Republic’s hold on the strait.
Oil prices climbed above $100 a barrel again for the first time since May and rose further on Monday after Saudi Arabia shut a major East‑West energy pipeline following damage from Iraqi drones.
U.S. West Texas Intermediate futures gained 2.3% to $102.39 per barrel, and Brent crude, the global benchmark, rose 2.4% to $107.11 per barrel.
