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. 

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, 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.

Your iPhone Has a Hidden Flight Tracker. Here’s How to Use It

Apple quietly built a real-time flight tracker into iOS.

Flying can introduce an entirely new layer of stress to any trip. Flight delays, cancellations and everything that could go wrong can keep you on edge, so staying up to date with your flight’s status is never far away from your mind.

Luckily, we’re in a world where finding the information for your flight is easily accessible. You can check your airline’s mobile app or even Google your flight number and the latest information is readily available. But did you know there’s a secret way to get your flight information on your iPhone

The iPhone has had a built-in flight tracker for some time now, but you’d never know it existed if you weren’t specifically looking for it — or searching for the correct terms to pull it up. 

Below, we’ll show you how to access the flight tracker so you’re just a tap away from the latest flight stats, giving you a little more peace of mind before your trip. 


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


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. 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.

Copilot Health Is Microsoft’s Doctor-Built Spin on Medical AI

Microsoft doesn’t want its AI to be your doctor. It wants to make you better prepared when you do see them.

Microsoft is taking a major swing at health AI. The company announced on Thursday that it’s introducing Copilot Health, a new experience inside its chatbot that will bring together all your medical records and wearable data with an AI that’s designed to help you understand it all.

«We are really on the cusp of building a true medical superintelligence,» said Mustafa Suleyman, Microsoft AI CEO. «One that can learn everything about you, all of your health conditions, from your wearable data, your electronic health records, and use that to provide support and insights and intelligence at your fingertips.»

A recent Microsoft survey found that mobile Copilot users ask the chatbot health-related queries more than for any other topic. Copilot Health was built to answer those questions. Microsoft’s health AI was fine-tuned by its in-house clinicians and an external panel of hundreds of clinicians in more than 24 countries. It uses the National Academy of Medicine’s framework for evaluating credible medical sources and information from Harvard Medical School via a 2025 licensing agreement.

Copilot Health is inside the regular, consumer version of Copilot. But it’s an entirely separate experience, designed that way to keep your health information separate from your usual chats. Because it’s been specifically trained for health questions, it ought to be more helpful and accurate than the regular version of Copilot or another chatbot. ChatGPT introduced a similar experience earlier this year.

Your health information won’t pop up in responses from the regular Copilot, only in the new health tab. You can delete your data at any time by simply toggling off a setting — something so easy it raises the question why all AI companies don’t make it that simple to delete your data.

Your information isn’t used to train Microsoft’s AI models, the company says. But your medical information in AI tools like Copilot is not protected under the Health Insurance Portability and Accountability Act (HIPAA).

The benefit of using Copilot Health is having a place where all your medical and health information lives, with an AI that’s trained to help answer your questions about it. You can connect data from your smartwatches and rings, as well as upload your medical records. Through a third-party program called HealthEx, you can upload files from multiple doctors’ offices, hospitals and labs at one time.

Copilot Health is not a doctor

If you choose to share your electronic health record, the AI can make more informed recommendations and reference specific doctors’ visit notes and lab results. But don’t use Copilot Health as a replacement for a physician. What the AI can do is discuss your health concerns, help you prepare for upcoming appointments and help you build healthier habits. 

«Copilot Health is not meant to give you a definitive diagnosis or a formal treatment plan, but it’s certainly here to support you in getting to the right answers,» said Dr. Dominic King, vice president of health at Microsoft AI. The former surgeon led the team that built Copilot Health.

For example, it can help you come up with a list of questions to ask your doctor, break down lab results and find a provider that accepts your insurance. Copilot Health can discuss your health concerns, like understanding any new symptoms, but it can’t diagnose or prescribe medication. 

Microsoft is doing a slow rollout, beginning with adults (ages 18 plus) in the US, with English as the only language. You can sign up to join the waitlist for Copilot Health now.

There are some existing uses of AI in health care today, but they’re disparate. Wearables have new AI-powered data insights and coaching. Some doctors are using AI scribe tools to take notes during appointments with patients. Administrative and insurance work also has its own AI tools, particularly around claims processing (including making denials, in some cases). The common thread is that none of the AI is without flaws, and it should never be used to make important decisions without human oversight.

For AI believers, the tangled, bureaucratic web of American health care is the perfect place to prove that AI intervention can make a real difference. But AI in health care is like putting a Band-Aid on a gunshot wound — a halfway measure that doesn’t fix the underlying problems. 

It’s too soon to tell if Microsoft’s goal of a medical superintelligence is viable. But for now, Copilot Health illustrates a more productive use of AI — more than filling the internet with slop.

«I think it is perhaps the most important and most positively impactful contribution that AI can make in the world,» Suleyman said. «And it’s enormously important to us.»
