Everything We Know About the Samsung Galaxy S23



It’s almost February, which means it’s time to turn our attention to what’s next for Samsung. The company just announced its next Unpacked event will take place on Feb. 1, and the Galaxy S23 lineup is expected to be the star of the show.

The Samsung Galaxy S22 range includes some of our top phones from 2022. The base S22 impressed as a more affordable option, the S22 Plus is a superb all-rounder while the all-powerful S22 Ultra blew us away with its stellar camera skills. We even gave the Plus and Ultra CNET Editors’ Choice Awards.

If Samsung maintains the pattern it’s followed for the last three generations, we can expect to see a Galaxy S23, Galaxy S23 Plus and Galaxy S23 Ultra. We’ll likely know more on Feb. 1, but here’s what we’re expecting based on rumors, leaks and Samsung’s previous product launches. As for what we want to see from the Galaxy S23 lineup, longer battery life and more clever camera features are at the top of my list.

Galaxy S23 release date

Samsung will likely announce the Galaxy S23 series during its next Unpacked event on Feb. 1, which will take place in San Francisco. The event announcement follows previous leaks, including this report from Korean newspaper JoongAng Daily, suggesting an early February launch for the Galaxy S23. A Jan. 6 tweet by prominent leaker Ice Universe also claimed to show a Galaxy Unpacked teaser image with a date of Feb. 1.


Whether the phones are available in stores to buy that month is another matter, as global supply chains are still struggling and it’s possible that there may be a longer delay than usual. But Samsung is already offering promotions for customers in the US who want to reserve a phone early. You’ll get $50 in Samsung credit if you sign up to reserve one device or $100 if you ask to reserve two.

The S22 Ultra has had some fierce competition this year, including from Google’s Pixel 7 Pro.

Galaxy S23 models and sizes

We firmly expect Samsung to continue its strategy of launching multiple phone models, each with different specs and prices to appeal to a wide variety of people. Based on Samsung’s history, we’re confident we’ll see an entry level Galaxy S23 model, a step-up S23 Plus with a larger screen and the top-end S23 Ultra. It’s the Ultra that will pack the best tech, including extra cameras, the biggest display and almost certainly the S Pen stylus.

Samsung’s Unpacked event invitation also includes what appear to be three spotlights, which may be a subtle nod to three new incoming Galaxy models.

Reputable leaker Ice Universe posted a detailed rundown of the sizes of the three upcoming phones (via GSM Arena), which put them almost exactly in line with the current sizes of the S22 lineup. As such, we don’t expect any notable differences in screen sizes of any of the range over the predecessors.

Those were 6.1 inches for the Galaxy S22, 6.6 inches for the S22 Plus and 6.8 inches for the S22 Ultra.

Galaxy S23 price

Assuming Samsung launches multiple models, the S23 range will come at three main prices. We don’t expect Samsung to stray from last year’s prices. For reference, the base S22 launched with a price of $800, while the Plus model started at $1,000 and the high-performance S22 Ultra debuted at $1,200 in the US last February.

Galaxy S23 cameras

The cameras look like they might be one of the key areas of focus for the new series. That’s likely to be especially true for the Ultra model, which is usually where Samsung’s biggest camera innovations can be found.

We expected the S22 Ultra to include a whopping 200-megapixel image sensor, considering Samsung has launched two of these image sensors and they can be found in other phones. We didn’t see it on the S22 Ultra, but it seems likely that a 200-megapixel sensor will be one of the key bragging rights of the S23 Ultra. Ice Universe also predicts that the Galaxy S23 Ultra’s will have a 200-megapixel sensor. It remains to be seen whether it’s the HP1 or HP3 sensor the company already produces or a new variant built specifically for the phone.

Samsung’s product pages for these sensors boast improved resolution (obviously), but also improved low-light photography by combining sets of smaller pixels into larger individual ones that can capture more light. The S22 Ultra is already one of the best night-time camera phones, beating out the Pixel 7 Pro in our recent tests, so a further burst to its low-light prowess is exciting to hear.

That massive resolution will also help with the phone’s zoom skills, which are already impressive thanks to its 10x optical zoom lens. Recent rumors from Ice Universe suggest that the lens lineup will remain the same across all phones, but that extra resolution should help make zoom shots even more pin-sharp.

There’s a chance we might also see a slight change in the camera’s design, at least on the Galaxy S23 Plus and potentially the Galaxy S23. Rumors from reputable leakers Ice Universe and Steve Hemmerstoffer suggest that the new devices could have circular cutouts for the camera lenses that sit directly on the back of the device rather than on a camera module. The Galaxy S22 Ultra already has a camera like this, but Hemmerstoffer’s leak suggests this style could make its way to the Plus model as well.

Take a look at the photos of the Galaxy S22 Ultra alongside the Galaxy S22 Plus and Galaxy S22 below to see what I mean.

Galaxy S23 battery, processor and other specs

The Galaxy S23 range will almost certainly use the latest Qualcomm Snapdragon 8 Gen 2 processor. In previous years, Samsung used its own Exynos chips for its European models. But a recent Qualcomm earnings call suggested that Samsung will in fact be using Qualcomm’s silicon for every phone in the range.

As for other specs, we expect a minimum of 8GB of RAM on the base models, with 12GB being available on the S23 Ultra. Storage is likely to continue to start at 128GB, with higher capacity options being available at higher prices. And no, we don’t expect a return of the microSD card slot to expand the storage. Sad face.

Recent Federal Communications Commission certifications show that the base S23 will have a 3,900-mAh battery, a step up from the 3,700 mAh of the base S23, while the S23 Plus will also get a battery boost to 4,700-mAh. There’s no official figure for the Ultra model yet, but again Ice Universe suggests that it will have the same 5,000-mAh cell size as the S22 Ultra.

We’ll likely know more as we progress through January and get toward that expected February launch date. But if the rumors turn out to be accurate, the Galaxy S23 lineup will probably be a modest step up from the Galaxy S22 family.

A Quick Guide to Better CMM Maintenance




A coordinate-measuring machine, also known as a CMM, is a specialized piece of equipment common in high-precision manufacturing. It uses coordinate technology to measure and replicate the dimensions of particular objects.

CMMs are a lot more accurate than regular measurement gauges. This characteristic makes them the equipment of choice for quality assurance in certain industries, like aerospace, defense, and medical manufacturing.

Despite being a powerful piece of equipment and the most versatile measuring tool in the metrology industry, CMMs can also be quite delicate. They require the right environment and proper maintenance practices to maintain accuracy and reliability.

The Importance of Proper CMM Maintenance

It’s essential to clean and inspect each part of your machine to ensure it stays efficient and accurate. Preventative maintenance ensures that your CMM remains accurate and performs at its best. It also improves your machine’s longevity.


Without proper CMM maintenance, you could risk damaging your CMM. Repairs would involve operational delays and additional costs.

CMM Preventative Maintenance Tips

Preventative maintenance practices are ones your team could do by yourselves. It’s best to schedule regular maintenance checks for your CMM daily, weekly, monthly, or quarterly. These checks can alert you immediately to possible problems with your CMM.

Remove dust and dirt regularly

Clean and well-maintained air bearings ensure your CMM works as it should. These frictionless and stable bearings help ensure accuracy and efficiency. Dust and dirt can clog your machine’s air bearings, affecting its overall performance.

Aside from your machine’s air bearings, dust could also get into other surfaces and crevices. These tiny particles could affect your machine’s accuracy.

Handle Stylus Tips Properly

The stylus is the tip that makes contact with the object you want to measure with your CMM. Despite this significant role, the stylus can be fragile and require careful handling. Too much force could cause it to bend or break.

Clean your stylus with a cleaning agent and a lint-free cloth. Make sure to remove any residue from workplace materials.

Ensure Good Air Quality

Most CMMs use air bearings, and good air quality is essential to keep them running smoothly. Various air quality issues could affect machine performance and even burn out machine motors.

For air quality maintenance, ask and address the following questions:

  • Do the lines have condensation, oil, or other contaminants?
  • Is the airflow constant?
  • Are you using the proper pressure?

When To Call a Professional

Most preventative maintenance practices are simple enough to be performed internally. However, some issues require professional attention. You can also conduct regular professional maintenance checks to ensure you don’t miss anything.

Below are some procedures that require professional assistance. Many CMM suppliers also offer maintenance services alongside their machinery.

Conducting CMM Training

CMMs are highly specialized pieces of equipment. To handle them properly, your staff needs professional training.

Training courses allow you to get trained by CMM experts on the tools and knowledge necessary within your industry. Regular training sessions also help keep you updated on industry trends and standards.

Sensor Malfunctions

CMM sensors are critical to your machine’s speed and accuracy. They should be professionally inspected and calibrated annually.

Routine sensor maintenance can significantly improve the efficiency and accuracy of your machine. CMM sensors include the following:

  • Scanning probe
  • Single point laser
  • Line laser
  • Electronic touch trigger probe
  • Video camera

Faulty Bearings

Neglected air bearings could cause them to falter in their accuracy and stability. Properly maintained air bearings ensure a smooth, stable, and accurate measurement process.

A professional metrology company can thoroughly inspect your air bearings to prevent further machine damage.

A CMM is a significant investment for any business. Good maintenance practices help your machine last and perform at its best, thus making the most out of this investment.

Nintendo’s discounted Switch game vouchers are back



Nintendo’s Switch Online service has become a better deal over time, offering more perks than just the ability to play games online. On top of getting access to SNES and NES classics, and cloud save backups (for most games, save a couple dozen), Nintendo announced an even bigger perk yesterday: discounted game vouchers.

All subscribers can buy a two-pack of these vouchers for $99.98, and a huge range of first-party (in other words, typically discount-averse) Nintendo games are looped in. I encourage you to check out the full list, but some highlights include the brand-new Fire Emblem Engage, Kirby’s Return to Dream Land Deluxe, Bayonetta Origins: Cereza and the Lost Demon, Metroid Dread, Splatoon 3, The Legend of Zelda: Breath of the Wild, and Pokémon Scarlet and Violet. Important note: you both have to be a subscriber to buy and use these vouchers.

It’s great that this list is more expansive than Nintendo’s first swing at this deal in 2019. But this perk could actually turn Switch Online into a must-have service because it allows you to pre-purchase up to four sets of vouchers (totaling eight games), and keep them for 12 months from the date of purchase. With $20 in savings with each pair of vouchers, buying four bundles will save you up to $80, assuming that each title normally costs $59.99. If you buy a lot of games, this is a smart way to save a little bit of money on every forthcoming purchase.

I know what you might be thinking: “Can I use one on The Legend of Zelda: Tears of the Kingdom?” Nintendo has not currently listed the deliriously anticipated sequel to Breath of the Wild, which is set to release on May 12th, 2023. Polygon has reached out to Nintendo to see if it’ll eventually become eligible, but did not hear back in time for publication.


You can get a free seven-day trial for Switch Online here, and you can easily subscribe to the service directly from the Switch’s eShop (it costs $3.99 per month, $7.99 for three months, or $19.99 per year). However, you can purchase (or gift) a one-year subscription with a digital code via Best Buy for $19.99. With a family subscription that costs $34.99 per year, up to eight Switch accounts can reap the perks of Switch Online.

For players who want all the perks, access to Goldeneye 007 and other N64 and Sega Genesis games, and complimentary DLC for some Switch games like Mario Kart 8 Deluxe, you’ll need Nintendo’s Switch Online plus the Expansion Pack tier, which costs $49.99 per year for one account, or $79.99 per year for a family subscription.

Canadian discovery could help batteries last longer



A chance discovery in a Canadian laboratory could help extend the life of laptop, phone and electric car batteries.

According to scientists from Dalhousie University in Halifax, common adhesive tape in batteries may be the reason many devices lose some of their power while off or not being used, which is a phenomenon known as self-discharge.

“In our laboratory we do many highly complex experiments to improve batteries, but this time we discovered a very simple thing,” Michael Metzger, an assistant professor in Dalhousie University’s physics and atmospheric science department, said in a news release. “In commercial battery cells there is tape—like Scotch tape—that holds the electrodes together and there is a chemical decomposition of this tape, which creates a molecule that leads to the self-discharge.”

The solution is simple, too, Metzger says: replace the polyethylene terephthalate, or PET, plastic tape commonly used inside batteries with something more durable and stable.


“It’s a commercially relevant discovery,” Metzger said. “It’s a small thing but it can definitely help improve battery cells.”

Metzger and his team have been trying to understand why lithium-ion battery cells in inactive devices tend to lose some of their power and self-discharge, something that has long frustrated consumers and manufacturers alike.

“Every manufacturer of lithium-ion cells in the world wants to make self-discharge as small as possible,” Metzger told in a joint statement with graduate student Anu Adamson. “In every battery there is a small rate of self-discharge that slowly drains the battery. This is very inconvenient for users and a big headache for industry.”

The electrodes that power batteries are separated by an electrolyte solution that is usually a form of lithium. After exposing several battery cells to different temperatures, researchers were surprised to see that electrolyte solution had turned bright red when it normally should be clear, which was something they had never encountered. The discovery was made by Adamson and two other students.

Chemical analysis of the red electrolyte solution revealed that at higher temperatures, a new molecule had been created inside the battery through the decomposition of common PET adhesive tape, which is often used to hold components together inside batteries. Strong and lightweight, PET is also frequently used for plastic packaging, drink bottles, clothing fibres and more.

Researchers realized that the red molecule, dimethyl terephthalate, was acting as a redox shuttle, meaning that it can transport electrons between a battery’s positive and negative electrodes, creating self-discharge and depleting power even when a battery is not in use. Ideally, the shuttling of electrons within a battery should only happen when a device is on.

“It’s a very simple thing—it is in every plastic bottle and no one would have thought that this has such a huge impact on how the lithium-ion cells degrade,” Metzger said in the news release. “It’s something we never expected because no one looks at these inactive components, these tapes and plastic foils in the battery cell, but it really needs to be considered if you want to limit side-reactions in the battery cell.”

The findings are outlined in a pair of studies published on Jan. 20 and Jan. 23 in the peer-reviewed Journal of The Electrochemical Society. The researchers are now testing PET tape substitutes.

“Since the PET in the tape is the culprit that creates the redox shuttle, we need to replace it with a polymer that is more stable and does not decompose in the harsh chemistry of a lithium-ion battery,” Metzger and Adamson told “So far, the results look very promising, and we plan to publish a new research paper on improved polymers for lithium-ion battery tapes soon.”

According to the researchers, their work has been attracting interest from “some of the world’s largest computer hardware companies and electric vehicle manufacturers,” which are eager to reduce self-discharge and improve battery performance.

“We visited some of these companies and they are planning to implement more stable polymers in their battery cells,” Metzger said.

In the release, Metzger noted: “One of the engineers said, ‘I heard you guys found out something is wrong with PET tape.’ So, I explained to him that it’s causing this self-discharge and asked him, ‘What are you using in your cells?’ He said, ‘PET tape.'”
