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.

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.

Samsung 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.

The Galaxy S23 family runs on a version of Qualcomm’s Snapdragon 8 Gen 2 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.

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).

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.

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

If 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.

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.

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).

If that’s not enough, you can try purchasing a portable charger or power bank to power up your device on the go.

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.

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.
