Battery Battle: Here’s Who Wins Between Galaxy S23 and Galaxy S22

The newest phone from Samsung has a larger battery. We compare to see which one has the most power.

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. Samsung addressed that shortcoming with the recently launched Galaxy S23, which has a larger battery and a more 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. 

Galaxy S23’s bigger battery makes a difference

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; last year’s device had 3,700 mAh. 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 been very different so far. I still had 64% of my battery left by 12:36 a.m. on a recent Sunday having taken the phone off its charger at 10 a.m. 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 phone’s 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 save that money.

Just make sure to purchase one of the best FDA-approved masks.

Movie projectors to backpack charms

If you’re looking for gifts across other categories, Google has some top 2025 searches for big and small. Home theaters are apparently in this year, as searches for movie projectors spiked by a whopping 945%. Searches for backpack charms also hit an all-time high this year, so those are a safe bet for stocking stuffing for any young kids.

Checkers (the actual board game)

Even though many gifts given out at Christmas this year will surely be high-tech gadgets and accessories, the board game of checkers is also on the list. There’s always room for the classics.

Look Up Tonight to Spot November’s Supermoon, the Brightest Moon of 2025

Has the moon been looking brighter and bigger to you for the past few days? Here’s why this month’s supermoon is even more super.

It’s already a great month for skygazers, with a trio of meteor showers and the return of the northern hemisphere winter constellations. On Tuesday night, it also features the second of four supermoons in a row. This month’s supermoon will happen on Nov. 4-5, and November’s beaver moon is special because it’ll be the brightest full moon of 2025. 

In addition to being a supermoon, November’s full moon is known as the beaver moon. There is some debate as to why it was named this way. Some believe that this was the best time of year in the old days to set beaver traps to get pelts for winter clothing. Others believe that it coincides with the busiest part of the year for beavers, who are now stocking their lodges with supplies for the upcoming winter. 

Here’s what time it’ll look its biggest and brightest, and what else you need to know about the November supermoon.

The brightest supermoon: When’s the best time to see it?

The moon will reach peak illumination at 8:19 a.m. ET on Nov. 5, making the evening of Nov. 4 and the morning of Nov. 5 the best times to view the moon.

Since moon phases shift slowly, the moon will appear almost full for nearly a week. If you are unable to view the full moon on its best night due to weather or other reasons, you can still see a mostly full moon at any point from Nov. 3 to Nov. 8. 

For all of those days, the moon will be measurably brighter in the night sky compared to any other full moon in 2025. The reason for this is because of the moon’s elliptical orbit. Since it’s not a perfect circle, the moon’s 27.3-day journey around the Earth brings it closer to us on some days, a phenomenon known as perigee. If there is a full moon during this time, it’s branded as a «perigean full moon,» which you may know better as a supermoon. 

Not all supermoons are equal, and November’s will be a little more special than others. According to The Farmer’s Almanac, the beaver moon will be a scant 221,817 miles away from Earth, making it the closest full moon of the year. That means it’ll be the biggest and brightest of the year. 

In practice, the differences are fairly minor and likely won’t be visible to the naked eye when compared side by side to other supermoons. A supermoon is only about 7% larger than a regular full moon. According to NASA, the biggest difference is when comparing a supermoon to a micromoon, where a supermoon will be about 14% larger and 30% brighter. So, if you notice that your backyard patio is lit up more than usual, it’s because of the supermoon. 

Also due to the moon’s orbit, November will also bring a micro new moon, which means the moon will be as far away from the Earth as it can get — a phenomenon known as apogee. November’s new moon occurs on Nov. 20, but you won’t be able to see it.

Stay Informed About Your Flights This Holiday Season With Your iPhone’s Tracker

Your iPhone is hiding a flight tracker. Here’s how it works.

Thanksgiving is only a few short weeks away and if you plan on flying during the holiday season, keeping up-to-date on changes to your flights is crucial. Airports can be hectic during any holiday, but with the government shutdown continuing, flights are liable to change or be cancelled more often.

Luckily, it’s never been easier to get up-to-date information about your flight. For starters, your airline probably has an app, and if not, you can check its website. If you’re in a hurry, you can Google the flight number. Or you can just use your iPhone’s built-in flight tracker that’s sneakily tucked away.

That’s right: Your iPhone has a flight tracker that you may have never known about. It’s there for when it’s needed. Below, we’ll show you have to access it in not one, but two places, so you never have to go hunting for your flight info elsewhere again.

How to track your flight via iMessage

Before we start, there are a few prerequisites you must meet:

  • Make sure iMessage is enabled (it doesn’t work with SMS/MMS).
  • You’ll need your flight number somewhere in your text messages, whether you’ve sent that information to someone (even yourself) or it’s been sent to you.
  • The flight number must be sent in this format: [Airline] [Flight number], for example, American Airlines 9707.

Launch the native Messages app on your iPhone and open the text message thread that contains your flight information. You’ll know the flight tracker feature works when the text with the flight information appears underlined, which means it’s actionable and you can tap on it. 

If your flight is still several months away or it’s already passed, you might see a message that says, «Flight information unavailable.» You might also see another flight that’s not yours because airlines recycle flight numbers.

You can check your flight status from Spotlight Search, too

If getting your flight information from Messages wasn’t easy enough, you can also grab the details right from your iPhone’s home screen by swiping down and adding your flight number into Spotlight Search. Even better, this works with Spotlight Search on your Mac computer, too. 

How to access the hidden flight tracker

Although the airline name/flight number format highlighted above is the best way to go, there are other texting options that will lead you to the same result. So let’s say we stick with American Airlines 9707, other options that may bring up the flight tracker include:

  • AmericanAirlines9707 (no spaces)
  • AmericanAirlines 9707 (only one space)
  • AA9707 (airline name is abbreviated and no space)
  • AA 9707 (abbreviated and space)

I would suggest you keep the airline name spelled out completely and add a space between the two pieces of information — like in the previous section — because for some airlines, these alternative options may not work.

Real-time flight tracking

Once everything is set, tap on the flight information in your text messages. If the feature works correctly, you should see the following two options appear in a quick-action menu:

  • Preview Flight: View the flight’s details. Tap this to view more information about the flight.
  • Copy Flight Code: Copy the flight code to your clipboard (in case you want to send your flight details to someone else via text or email).

If you select Preview Flight, at the top of the window, you’ll see the best part of this feature: a real-time flight tracker map. A line will connect the two destinations, and a tiny airplane will move between them, indicating where the flight is at that exact moment.

Underneath the map, you’ll see important flight information:

  • Airline name and flight number
  • Flight status (arriving on time, delayed, canceled, etc.)
  • Terminal and gate numbers (for arrival and departure)
  • Arrival and departure time
  • Flight duration
  • Baggage claim (the number of the baggage carousel)

If you swipe left on the bottom half of the flight tracker, you can switch between flights, but only if there’s a return flight.
