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.

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.

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

With 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.

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.

Galaxy S23 vs. Galaxy S21

The differences between the Galaxy S23 and Galaxy S21 are more noticeable, but you can probably hold onto your S21 for another year before upgrading.

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.

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.

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.

Galaxy S23 vs. Galaxy S20

Whether 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.

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.

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.

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.

Galaxy S23 vs. Galaxy S10

The Samsung Galaxy S10 lineup.

Angela Lang/CNET

Galaxy 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.

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).

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.

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.

Galaxy S23 vs. Galaxy S9

James Martin/CNET

There are many reasons to upgrade from the Galaxy S9 — 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.

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.

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.

The bottom line: 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.

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.

Get Ready for a Striking Aurora That Could Also Disrupt Radio Communications

Don’t expect the storm to cause a lingering problem, though.

A geomagnetic storm is threatening radio communications Monday night, but that doesn’t mean you should be concerned. In fact, it may be an opportunity to see a colorful aurora in the night sky.

The National Oceanic and Atmospheric Administration has issued a geomagnetic storm watch after witnessing a coronal mass ejection from the sun on Saturday. The watch, which was issued over the weekend and will expire after Monday, said the onset of the storm passing over Earth on Sunday night represented a «moderate» threat to communications. As the storm continues to pass through, it could deliver a «strong» threat on Monday night that could cause radio communications to be temporarily disrupted during the worst of it.

Even so, NOAA said, «the general public should not be concerned.»

A coronal mass ejection occurs when magnetic field and plasma mass are violently expelled from the sun’s corona, or the outermost portion of the sun’s atmosphere. In the vast majority of cases, the ejection occurs with no real threat to Earth. However, in the event the ejection happens in the planet’s direction, a geomagnetic storm occurs, and the Earth’s magnetic field is temporarily affected.

In most cases, geomagnetic storms cause little to no disruption on Earth, with radio communications and satellites affected most often. In extreme cases, a geomagnetic storm can cause significant and potentially life-threatening power outages — a prospect that, luckily, the planet hasn’t faced.

Switching poles

Every 11 years, the sun’s magnetic poles switch, with the north pole and south pole swapping positions. During those cycles, the sun’s activity ramps up as it gets closer to pole-switching time. The height of its activity is called solar maximum, and scientists believe we either may be entering the solar maximum or may be already in it.

During periods of heightened solar activity, sunspots increase on the sun and there’s an increase in coronal mass ejections, among other phenomena. According to NOAA, solar maximum could extend into October of this year before the sun’s activity calms and it works towards its less-active phase, solar minimum.

Even when geomagnetic storms hit Earth and disrupt communications, the effects are usually short-lived. Those most affected, including power grid operators and pilots and air traffic controllers communicating over long distances, have fail-safe technologies and backup communications to ensure operational continuity.

But geomagnetic storms aren’t only about radios. In most cases, they also present unique opportunities to see auroras in the night sky. When the storms hit, the plasma they carry creates a jaw-dropping aurora, illuminating the night sky with brilliant colors. Those auroras can be especially pronounced during the most intense phases of the storm, making for nice stargazing.

If you’re interested in seeing the aurora, you’ll need to be ready. The NOAA said the «brunt of the storm has passed» and even if it lingers into Tuesday, there won’t be much to see after Monday night.

Last Total Solar Eclipse for 20 Years Is Coming: How to See and Photograph It

It’s your last chance until 2044.

Get your eclipse glasses ready, Skygazers: the Great American Eclipse is on its way. On April 8, there’ll be a total eclipse over North America, the last one until 2044.

A total solar eclipse happens when the moon passes between the Earth and the sun, blocking the sun and turning an otherwise sunny day to darkness for a short period of time. Depending on the angle at which you’re viewing the eclipse, you may see the sun completely shrouded by the moon (called totality) or some variation of it. The more off-angle you are and the further you are from the path of the eclipse, the less likely you’ll be to see the totality.

The 2024 total solar eclipse will happen on Monday, April 8. The Great American Eclipse will reach the Mexican Pacific coast at 11:07 a.m. PT (2:07 p.m. ET), and then traverse the US in a northeasterly direction from Texas to Maine, and on into easternmost Canada. If you want a good look at it, but don’t live in the path of totality, you shouldn’t wait much longer to book accommodation and travel to a spot on the path.

Or how about booking a seat in the sky? Delta Airlines made headlines for offering a flight that allows you to see the entire path of totality. Its first eclipse flight, from Austin, Texas, to Detroit sold out quickly. But as of Monday, Delta has added a second flight from Dallas to Detroit, which also covers the path of totality. The airline also has five flights that will offer prime eclipse viewing.

Not everyone can get on one of those elusive eclipse-viewing flights. Here’s a look at other options to nab a chance to see this rare sight and what to know about it.

Total solar eclipse path

The eclipse will cross over the Pacific coast of Mexico and head northeast over mainland Mexico. The eclipse will then make its way over San Antonio at approximately 2:30 p.m. ET on April 8 and move through Texas, over the southeastern part of Oklahoma and northern Arkansas by 2:50 p.m. ET.

By 3 p.m. ET, the eclipse will be over southern Illinois, and just 5 minutes later, will be traveling over Indianapolis. Folks in northwestern Ohio will be treated to the eclipse by 3:15 p.m. ET, and it will then travel over Lake Erie and Buffalo, New York, by 3:20 p.m. ET. Over the next 10 minutes, the eclipse will be seen over northern New York state, then over Vermont. By 3:35 p.m. ET, the eclipse will work its way into Canada and off the Eastern coast of North America.

Best places to watch the Great American Eclipse

When evaluating the best places to watch this year’s total eclipse, you’ll first want to determine where you’ll have the best angle to see the totality. The farther off-angle you are — in other words, the farther north or south of the eclipse’s path — the less of an impact you can expect.

Therefore, if you want to have the best chance of experiencing the eclipse, you’ll want to be in its path. As of this writing, most of the cities in the eclipse’s path have some hotel availability, but recent reports have suggested that rooms are booking up. And as more rooms are booked, prices are going up.

So if you want to be in the eclipse’s path, and need a hotel to do it, move fast. And Delta’s eclipse-viewing flight from Dallas to Detroit has just four seats left at the time of publication.

Eclipse eye safety and photography

As with any solar eclipse, it’s critical you keep eye safety in mind.

During the eclipse, and especially during the periods before and after totality, don’t look directly at the sun without special eye protection. Also, be sure not to look at the sun through a camera (including the camera on your phone), binoculars, a telescope or any other viewing device. This could cause serious eye injury. Sunglasses aren’t enough to protect your eyes from damage.

If you want to view the eclipse, you’ll instead need solar viewing glasses that comply with the ISO 12312-2 safety standard. Anything that doesn’t meet that standard or greater won’t be dark enough to protect your eyes. Want to get them for free? If you’ve got a Warby Parker eyeglasses store nearby, the company is giving away free, ISO-certified solar eclipse glasses at all of its stores from April 1 until the eclipse, while supplies last.

If you don’t have eclipse viewing glasses handy, you can instead use indirect methods for viewing the eclipse, like a pinhole projector.

In the event you want to take pictures of the eclipse, attach a certified solar filter to your camera. Doing so will protect your eyes and allow you to take photos while you view the eclipse through your lens.

There’s also a new app to help you both protect your eyes and take better photos of the eclipse on your phone. Solar Snap, designed by a former Hubble Space Telescope astronomer, comes with a Solar Snap camera filter that attaches to the back of an iPhone or Android phone, along with solar eclipse glasses for protecting your eyesight during the event. After you attach the filter to your phone, you can use the free Solar Snap Eclipse app to zoom in on the eclipse, adjust exposure and other camera settings, and ultimately take better shots of the eclipse.

2024 eclipse compared to 2017

The last total solar eclipse occurred in 2017, and many Americans had a great view. Although there are plenty of similarities between the 2017 total solar eclipse and the one coming April 8, there are a handful of differences. Mainly, the 2024 eclipse is going to cover more land and last longer.

The 2017 eclipse started over the northwest US and moved southeast. Additionally, that eclipse’s path was up to 71 miles wide, compared with a maximum width of 122 miles for this year’s eclipse. Perhaps most importantly, the moon completely covered the sun for just 2 minutes, 40 seconds in 2017. This year, maximum totality will last for nearly four-and-a-half minutes.
