Samsung Galaxy S23 and S23 Plus Review: It’s All About the Battery Life

These new phones fix the Galaxy S22’s biggest problem.

This story is part of Samsung Event, CNET’s collection of news, tips and advice around Samsung’s most popular products.

Samsung hasn’t been shy about flaunting the cameras on its new phones. It even wrangled endorsements from acclaimed directors Ridley Scott and Na Hong-jin during its Galaxy S23 announcement. However, in a surprising move for Samsung, the camera plays second fiddle to battery and performance upgrades in the new Galaxy S23 and S23 Plus.

The Galaxy S23 ($800, 849, AU$1,349) and Galaxy S23 Plus ($1,000, 1,049, AU$1,649), which are available today alongside the $1,200 Galaxy S23 Ultra ( 1,249, AU$1,949), feel like a half-generation upgrade compared to last year’s Galaxy S22.

Performance is faster, and battery life is thankfully a bit longer, which addresses the biggest complaint I had about the Galaxy S22. But unlike the Galaxy S23 Ultra’s cameras, which have noticeable improvements in color tone and dynamic range along with a new 200-megapixel sensor, the Galaxy S23 and S23 Plus’ cameras largely feel the same as last year.

And that’s OK. We’re past the point of revolutionary annual upgrades, and the Galaxy S23 is the perfect example of that. Instead, Samsung focused on making practical refinements to one of the areas that matters most in a phone: how long it lasts on a single charge. Still, you shouldn’t upgrade to the S23 or S23 Plus unless your phone is more than two years old since it’s not a radical change.

One of the Galaxy S23’s biggest drawbacks, however, isn’t a flaw with the phone itself, but rather the tough competition from Google. The $899 Pixel 7 Pro falls in between the Galaxy S23 and S23 Plus pricewise and offers a stellar camera that bests Samsung’s in some scenarios. Samsung, however, does offer compelling trade-in bargains that could make the S23 lineup more compelling.

Overall, the Galaxy S23 is ideal for Android fans that prioritize fast performance, solid cameras and having a spacious and bright screen in a compact package. The Galaxy S23’s cameras don’t always measure up to Apple’s and Google’s, but they’re still good enough to fit most peoples’ needs.

Galaxy S23 and S23 Plus get a battery upgrade

Like the Galaxy S22, the 6.1-inch Galaxy S23 remains a top choice for Android fans that prefer smaller phones. But there was just one problem with the Galaxy S22: Its battery life sometimes felt too short to get through a full day.

It looks like Samsung took these concerns to heart. Both the regular Galaxy S23 and the larger 6.6-inch Galaxy S23 Plus get a longer battery life compared to their predecessors. The Galaxy S23 has a 3,900-mAh battery, up from the Galaxy S22’s 3,700-mAh capacity, while the Galaxy S23 Plus has a 4,700-mAh battery instead of the S22 Plus’ 4,500-mAh battery. The new Qualcomm Snapdragon 8 Gen 2 processor inside the Galaxy S23 series, which has been optimized for Samsung’s new phones, should also bring some improvements to power efficiency.

Even though I’ve only used the new phones for a few days, these upgrades are already noticeable. When I used the 6.1-inch Galaxy S22 as my daily smartphone for roughly a month, I noticed that the battery dipped down to between 30 and 40% by 9 p.m., especially after a long day in the office.

With the Galaxy S23, the battery was down to 46% by 9:45 p.m. after a day of heavy usage (running benchmark performance tests, taking lots of photos and videos, etc.). With light usage after a day that started at 10 a.m, I had 64% left by the time I went to sleep just past 12:30 a.m. The Galaxy S23 Plus had 73% of its battery left by bedtime (around 11 p.m.) after a full day in the office.

Of course, battery life will vary depending on how you use your device. Tasks like making video calls and recording video will drain the battery faster, and settings such as screen brightness typically impact battery life. During my tests, I usually had the screen set between 25% and 50% of the phone’s maximum brightness; since Samsung’s phones have fairly bright screens, there’s usually no need to set it any higher.

I also tested the battery life by putting each phone through a 45-minute endurance test to see how quickly the battery drains after routine tasks like scrolling through social media, watching YouTube videos, playing games and making a video call. The Galaxy S23 dipped to 91% after that test, while the Galaxy S23 Plus decreased to 95%. Both scores represent a mild improvement over the Galaxy S22 and S22 Plus, which reached 89% and 92%, respectively.

To get a more thorough sense of the Galaxy S23’s battery life, I also ran a three-hour YouTube streaming test in which I cranked the display brightness all the way up while watching a video and measured the battery level at every hour. As you can see in the table below, the Galaxy S23 and S23 Plus fared better than their predecessors during these tests, especially by the end of the third hour. Both phones also beat the Galaxy S22 Ultra in this test, and the Galaxy S23 matched the performance of the $599 Pixel 7.

While battery life improved, the Galaxy S23 and S23 Plus have the same charging speeds as last year. The Galaxy S23 supports 25-watt fast-charging and 45-watt fast-charging for the Galaxy S23 Plus. But in practice, those charging speeds didn’t feel that different. The Galaxy S23 went from 47% to 86% after 30 minutes, while the Galaxy S23 Plus went from 59% to 94%.

While charging speed isn’t a deal-breaker when buying a new phone, it would have been nice to see Samsung push forward in this area. That’s especially true considering rivals like Xiaomi and OnePlus continue to shorten the time it takes to replenish their respective phones’ batteries.

Galaxy S23 and S23 Plus’ new processor is fast

The Galaxy S23 and S23 Plus feel snappy and fast in everyday use, as phones in their price range should. Playing games with the graphics and frame rate at the highest settings felt smooth, and apps launched instantly. All three new phones have an adaptive refresh rate that reaches up to 120Hz for smoother scrolling and animations, which also contributes to the devices’ peppiness.

The one area where the new Qualcomm Snapdragon 8 Gen 2 processor seems to make a difference in everyday use is exporting video. The Galaxy S23 and S23 Plus both exported a 30-second 4K video to 1080p faster than the Galaxy S22 Ultra and Pixel 7 Pro. The iPhone 14, however, was the fastest of the bunch. The Galaxy S23 lineup runs on a special customized version of Qualcomm’s latest mobile chip that’s been optimized for these phones, meaning it’s different from the version inside the OnePlus 11.

Benchmarks meant to test general computing (Geekbench 5) and how a processor handles high performance in short bursts (3DMark) told a similar story. The Galaxy S23 and S23 Plus performed well compared to the Galaxy S22 and Pixel 7 Pro, and even outperformed the iPhone 14 on most tests. The OnePlus 11 was their closest competitor, which isn’t surprising considering it has a similar processor. But the Galaxy S23 and S23 Plus did outpace the OnePlus 11 in the test meant to evaluate a processor’s single-core performance, which makes sense considering Samsung overclocked one of the CPU cores.

That said, real-world usage matters more than benchmarks. Other than the faster video export speeds, I didn’t experience anything on the Galaxy S23 lineup that felt unusually fast compared to most other phones in the same price range.

Galaxy S23 and S23 Plus camera is similar to the S22

The Galaxy S23 and S23 Plus each have a triple rear camera that consists of a 50-megapixel main camera, 12-megapixel ultra wide and a 10-megapixel telephoto. Thanks to a technique called pixel binning, you can choose to shoot photos at the full 50-megapixel resolution or 12 megapixels depending on the scenario. The 12-megapixel option, for example, is usually better for poorly lit circumstances since it groups multiple pixels together to serve as a larger pixel for gathering more light. Samsung also integrates the controls from its Expert Raw app right into the main camera, making it more convenient for those who want easy access to the full, uncompressed version of an image.

This camera system is largely the same as the one on the S22, although Samsung has made some processing improvements, particularly when it comes to low light photography. That’s the biggest difference I noticed during my time testing the new phones against the Galaxy S22.

Check out the photos of my husband in a dim restaurant below. His face is brighter and his beard is more detailed.

Still, I preferred the iPhone 14’s and Pixel 7 Pro’s images, mostly because they captured more accurate skin tones. The Galaxy S23’s photo is brighter and more detailed than the Pixel 7 Pro’s, but it also makes his face look a little washed out.

The Galaxy S23 performs well in dim conditions overall, which isn’t surprising considering low-light photography has been a big area of focus for Samsung in recent years. Even though the iPhone 14 and Pixel 7 Pro performed better in the examples above, the S23 easily challenges Apple and Google in other low-light photography scenarios, like taking photos of pets and still objects.

In the photos of a book stack below, for example, the Galaxy S23 did a great job at retaining detail and color. The iPhone 14’s photo isn’t as colorful and has some noise compared to Samsung’s, although the Pixel 7 Pro’s image was a close competitor.

Otherwise, there isn’t anything that feels new or surprising about the Galaxy S23’s camera. While the Galaxy S23 and S23 Plus can both capture crisp and clear images, there were instances in which colors either looked exaggerated or blown out compared to the same photos taken on the iPhone 14 and Pixel 7.

You can see an example of the exaggeration in this photo of my husband below. The shade of blue in his denim jacket is brighter than it looked in real life, while the iPhone 14 and Pixel 7 Pro’s photos look more natural.

But as I said in my review of the S23 Ultra, this isn’t always a bad thing. It can make certain photos pop and look more attractive overall, as is the case with the photo below. The pink flowers look more colorful and vibrant in the S23’s photo compared to the rest.

Samsung also upgraded the Galaxy S23’s selfie camera with a 12-megapixel sensor compared to the S22’s 10-megapixel front camera. However, I didn’t notice much of a difference under normal circumstances.

But Samsung’s phones easily took better selfies in low light compared to the iPhone 14 and Pixel 7 Pro. The photos from Google and Apple’s phones are both noisier and grainier than Samsung’s, which I noticed when comparing the photos on a large monitor. The Galaxy S23’s selfie is also a bit clearer than the S22’s, but the difference isn’t as dramatic.

The Galaxy S23 and S23 Plus have a 3x optical zoom and 30x digital zoom, just like the S22 and S22 Plus. You’ll need to splurge on the $1,200 Galaxy S23 Ultra to get the 10x optical zoom and 100x digital zoom.

But the S23 and S23 Plus still have more to offer than the $799 iPhone 14, which has a 1x optical zoom and a 5x digital zoom.

Samsung is usually the king of zoom, but in this scenario Google takes the cake. The Pixel 7 Pro has a 5x optical zoom and a 30x digital zoom that looks far crisper than Samsung’s, as shown below.

As far as video recording is concerned, the S23 and S23 Plus can record at 8K resolution up to 30 frames per second. When recording video at the highest supported resolution and frame rate for each phone (4K at 60 frames per second for the iPhone 14 and Pixel 7 Pro), I noticed the Galaxy S23’s footage had more accurate color tones compared to the Pixel 7 Pro. The iPhone’s video, however, looked a bit crisper.

I also noticed that video stabilization improved slightly on the Galaxy S23 compared to the Galaxy S22, enabling it to better compete with Apple’s Action Mode.

The Galaxy S23’s camera isn’t a leap forward, but it’ll feel significant to those upgrading from a phone that’s several years old.

Galaxy S23 and S23 Plus have a slightly new design

The Galaxy S23 and S23 Plus have largely the same appearance and feel as the Galaxy S22. And that’s a good thing in my opinion, because I loved the Galaxy S22’s sleek and colorful look.

The main difference is that Samsung did away with the camera island on the Galaxy S23 and S23 Plus, instead opting for standalone lenses that sit arranged in a vertical column on the back of the device. It’s the same aesthetic as the Galaxy S23 Ultra, and it makes the S23’s design feel more consistent. Otherwise, the phones are available in new color options that include lavender, black, cream and green.

All three phones come in the same size options as the S22 lineup. There’s the 6.1-inch Galaxy S23, 6.6-inch Galaxy S23 Plus and 6.8-inch Galaxy S23 Ultra. Samsung does a better job than most at squeezing spacious screens into small devices. The Galaxy S23 Ultra still feels massive, but the Galaxy S23 and S23 Plus feel surprisingly petite for their size.

The Galaxy S23 Plus, for example, only feels slightly larger than the 6.1-inch iPhone 14 despite the amount of extra screen space it provides. The Galaxy S23 is also one of the few Android phones with a 6.1-inch screen other than the Pixel 6A, making it a compelling choice for those who prefer compact devices.

All three new Galaxy phones launch with Android 13 and the One UI 5.1 overlay. Samsung also provides four generations of Android OS version upgrades, which is noteworthy considering Google only commits to three generations of updates on its Pixel phones. That means your Galaxy S23 will last for at least four years from a software perspective, so it shouldn’t feel outdated anytime soon.

Consistent with Samsung’s theme of making practical changes this year, the Galaxy S23 Plus and S23 Ultra now start at 256GB of storage rather than 128GB. That means you get double the storage capacity for the same price as last year’s devices. While it’s a great value for Samsung’s pricier phones, I’m disappointed Samsung didn’t do the same for its entry-level Galaxy S23. It would have been a good way for Samsung to further justify the Galaxy S23’s higher price compared to the $599 Pixel 7 while also giving potential Pixel 7 Pro shoppers another reason to consider Samsung instead.

Galaxy S23 and S23 Plus: Buy or skip?

The Galaxy S23 and S23 Plus are moderate improvements over the Galaxy S22, bringing quality-of-life improvements like longer battery life, more base storage for the Plus and faster performance. Since this isn’t a major update, I don’t recommend upgrading unless you have a phone that’s more than two years old at the very least. Those who have an older phone will get the benefits that came with last year’s camera upgrade and redesign, along with the S23’s better battery life.

If you’re shopping in the $900 price range, the Pixel 7 Pro is also worth considering. The camera generally captures more accurate colors and crisper zoom shots than Samsung’s and you get a slightly larger screen for a cheaper price than the Galaxy S23 Plus. However, just remember that Google only offers three generations of Android OS updates for the Pixel 7 line, so you might want to upgrade sooner. Both Samsung and Google provide five years of security updates for their higher-end devices, so you’ll still have years before the phones may be susceptible to vulnerabilities.

The Galaxy S22 is also a tempting option at its new price of $700. But if you can afford it, I’d recommend going for the Galaxy S23 because of its longer battery life and newer processor. Let’s face it, your phone’s battery isn’t going to get any better over time, so you might as well invest in a device that will last longer.

How we test phones

Every phone tested by CNET’s reviews team was actually used in the real world. We test a phone’s features, play games and take photos. We examine the display to see if it’s bright, sharp and vibrant. We analyze the design and build to see how it is to hold and whether it has an IP-rating for water resistance. We push the processor’s performance to the extremes using both standardized benchmark tools like GeekBench and 3DMark, along with our own anecdotal observations navigating the interface, recording high-resolution videos and playing graphically intense games at high refresh rates.

All the cameras are tested in a variety of conditions from bright sunlight to dark indoor scenes. We try out special features like night mode and portrait mode and compare our findings against similarly priced competing phones. We also check out the battery life by using it daily as well as running a series of battery drain tests.

We take into account additional features like support for 5G, satellite connectivity, fingerprint and face sensors, stylus support, fast charging speeds, foldable displays among others that can be useful. And we of course balance all of this against the price to give you the verdict on whether that phone, whatever price it is, actually represents good value.

Judge Blocks Texas App Store Age-Check Law

A preliminary injunction found the Texas law, set to begin Jan. 1, is «more likely than not unconstitutional.»

A new Texas state law set to take effect on Jan. 1 would have required app stores to implement age verification processes. But the law has been put on hold, at least temporarily, by a federal court judge.

As reported by the Texas Tribune, Senate Bill 2420, also known as the Texas App Store Accountability Act, is the subject of a temporary injunction issued by US District Judge Robert Pitman.

Pitman said in his decision that the law as written is broad, vague and «more likely than not unconstitutional.» However, he also wrote the court «recognizes the importance of ongoing efforts to better safeguard children when they are on their devices.»

The Texas law, signed into law by Governor Greg Abbott in May, requires app store operators — including Apple, Google, Nintendo, Steam and more — to build age verification processes for the storefronts and to only allow downloads to minors who obtain parental consent. The injunction is a ruling in an October lawsuit filed by the Computer & Communication Industry Association.

CCIA senior vice president Stephanie Joyce said in a statement, «This Order stops the Texas App Store Accountability Act from taking effect in order to preserve the First Amendment rights of app stores, app developers, parents, and younger internet users. It also protects parents’ inviolate right to use their own judgment in safeguarding their children online using the myriad tools our members provide.»

Other individuals and the advocacy group Students Engaged in Advancing Texas also filed suits over the law, the Texas Tribune reported.

App Store Accountability Act

The bill author, State Senator Angela Paxton, said the bill was meant to give parents «common sense tools to protect their kids and to survive court challenges by those who may have lesser priorities.»

The language of Texas Senate Bill 2420 does not only include mobile app stores from Apple or Google, but any «website, software application, or other electronic service that distributes software applications from the owner or developer of a software application to the user of a mobile device.»

By that definition, websites with links to browser games or mobile game consoles with download options would fall under the Texas law as written. The law also defines mobile devices as including phones and tablets, as well as any other handheld device capable of transmitting or storing information wirelessly.

The parental consent aspect of the law requires those under 18 to have an app store account affiliated with a parent or guardian to purchase or download applications.

Age verification elsewhere

In an effort to keep adult materials out of reach of minors and to protect children from potentially harmful content and interactions, tech companies have been compelled by law or through legal action to verify the age of users.

Roblox, which has a huge audience of minors, began rolling out stricter age verification after investigations and lawsuits hurt its reputation as a safe gaming space. Australia is perhaps the most large-scale example of a government restricting access to online content. In December, Australia began restricting social media access to those 16 and older. Reddit recently challenged that law.

In the US, age verification laws have primarily targeted adult sites. Texas already has a law on the books that requires adult sites to age-block their content. The Supreme Court upheld that law in a June ruling. The UK has also enacted age restriction rules for adult sites as have other US states.

Don’t Let a Border Agent Ruin Your Holiday Trip. Travel With a Burner Phone

Yes, you should leave your main phone at home and take a cheap burner this winter.

Prepare for a whole new level of border-crossing anxiety this holiday season: the high-probability of a phone search. New figures from US Customs and Border Protection say agents aren’t just glancing at your lock screen anymore — they are aggressively ramping up device inspections, even for citizens coming home. We aren’t just talking about a quick scroll through your photos, either. Agents are increasingly using forensic tools to clone and analyze everything on your device.

The stats are genuinely alarming. In just a three-month window this year, nearly 15,000 devices were flagged for searches, with over a thousand subjected to deep-dive data copying. If you’re traveling with your primary phone, you are essentially carrying your entire digital existence into a legal gray zone where privacy is optional.

The smartest defensive play is remarkably low-tech: the burner phone. By traveling with a secondary, stripped-down device, you ensure your private data stays safe at home while you stay connected abroad. But privacy isn’t the only perk. Moving to a «dumb» phone is the ultimate digital detox, helping you escape the notification trap that usually ruins a vacation.

Even figures like Conan O’Brien have ditched the smartphone to cut through the noise. Whether you’re dodging invasive border searches or just trying to enjoy your trip without being glued to a screen, a burner might be the best travel investment you make this year.

Although carriers have offered prepaid phones since the ’90s, «burner phones» or «burners» became popular in the 2000s following the celebrated HBO series The Wire, where they helped characters avoid getting caught by the police. Although often portrayed in that light, burners aren’t only used by criminals; they’re also used anyone concerned with surveillance or privacy infringement.

What is a burner phone, and how does it work? Here’s everything you need to know about burners and how to get one.

Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.

What is a burner phone?

A burner phone is a cheap prepaid phone with no commitments. It comes with a set number of prepaid call minutes, text messages or data, and it’s designed to be disposed of after use.

Burner phones are typically used when you need a phone quickly, without intentions of long-term use. They’re contract-free, and you can grab them off the counter. They’re called burner phones because you can «burn» them (trash them) after use, and the phone can’t be traced back to you, which makes them appealing to criminals. Of course, those committed to illicit activities often do more than just throw these phones in the trash, and often completely obliterate the SIM cards and other materials by smashing them with a hammer or melting them away.

Burners are different from getting a regular, contract-bound cellphone plan that requires your information to be on file.

Why should you use a burner phone?

Burner phones are an easy way to avoid cellphone contracts or spam that you get on your primary phone number. Burners aren’t linked to your identity, so you can avoid being tracked down or contacted.

You don’t have to dispose of a burner phone after use. You can add more minutes and continue using it. Burner phones can still function as regular phones, minus the hassle of a contract.

You can also get a burner phone as a secondary phone for a specific purpose, like having a spare phone number for two-factor authentication texts, for business or to avoid roaming charges while traveling. Burner phones are often used by anyone concerned with privacy.

Burner phones, prepaid phones, smartphones and burner SIMs: What’s the difference?

Burner phones are cheap phones with simple designs that lack the bells and whistles of a smartphone. Because they’re designed to be disposable, you only get the essentials, as seen by the most common version, the flip phone.

All burner phones are prepaid phones, but not all prepaid phones are burners. What sets a burner apart is that you won’t have to give away any personal information to get one, and it won’t be traceable back to you. Again, a burner phone is cheap enough to be destroyed after use.

Prepaid smartphones are generally low-end models. You can use any unlocked smartphone with prepaid SIM cards, essentially making it a prepaid phone.

If you want a burner, you don’t necessarily have to buy a new phone. You can get a burner SIM and use it with an existing phone. Burner SIMs are prepaid SIMs you can get without a contract or giving away personal information.

Where can you buy a burner phone?

Burner phones are available at all major retail outlets, including Best Buy, Target and Walmart. They’re also often available at convenience stores like 7-Eleven, local supermarkets, gas stations and retail phone outlets like Cricket and Metro.

You can get a burner phone with cash, and it should cost between $10 and $50, although it may cost more if you get more minutes and data. If you’re getting a burner phone specifically to avoid having the phone traced back to you, it makes sense to pay with cash instead of a credit card.

If you just want a prepaid secondary phone, you can use a credit card. Just keep in mind that credit cards leave a trail that leads back to you.

There are also many apps that let you get secondary phone numbers, including Google Fi and the Burner app. However, these aren’t burners necessarily because the providers typically have at least some of your personal information. Additionally, apps like Google Talk require a phone number that’s already in use for you to choose a number with the service.
