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.

Before Apple’s Expected iOS 19 Reveal, Here’s What to Know About iOS 18.5

Here are all the new features you should know about in the latest iPhone update.

Apple is holding its Worldwide Developers Conference on June 9, where we will likely get a glimpse of the upcoming iOS 19. Before that announcement, Apple released iOS 18.5 on May 12, more than a month after the company released iOS 18.4. While iOS 18.4 brought more emoji to all iPhones, this latest update adds just a few small changes and a new Pride wallpaper to your iPhone. The update also includes some bug fixes and security patches everyone should download to help keep their device secure. 

Read more: What CNET’s Experts Hope to See in iOS 19

You can download iOS 18.5 by going to Settings > General > Software Update, then tapping Update Now and following the prompts on your screen.

Here’s what iOS 18.5 brings to your iPhone. Just a reminder, only people with an iPhone 15 Pro, Pro Max or the iPhone 16 lineup can access Apple Intelligence for now. If you have any other iPhone, you won’t have access to those features.

New Pride wallpaper

Apple releases a new Pride wallpaper ahead of Pride Month every year, and this year is no different. iOS 18.5 includes the latest iteration of the wallpaper, «Pride Harmony,» which features bold stripes that shift and change position as you move. 

iOS 18.5 tweaks Mail options

Apple introduced a few Mail app updates in iOS 18.5. One of those updates makes it easier to adjust the app’s settings by showing or hiding contact photos in Mail. Contact photos are the images to the left of emails that help identify senders. 

Mail will show Contact Posters by default, but you can turn them off from within the app with iOS 18.5. To do so, open Mail, tap the three dots () in the top-right corner of your screen, and then tap Show Contact Photos. Now, all your emails will just show the subject line and a preview of the message, similar to how Mail looked before iOS 18.

This option is in iOS 18.4, but it’s buried in Settings and not easy to locate. 

Another update concerns Categories. If the mode is enabled, you can see a small tab on the right side of your screen near the other categories. Swipe the categories bar near the top of Mail to the left, and this small tab will expand to reveal the category All Mail. When you swipe left to view All Mail, it will automatically be selected, and you’ll need to tap one of the other Categories to unselect All Mail.

This category isn’t new; you could find it in iOS 18.4. But, there was no small tab on the right side of your screen to signal it was present off-screen. Therefore, All Mail flew under the radar — I didn’t even know the option was there until beta versions of iOS 18.5.

This category appears to be a way to simultaneously enable Categories and List View — the pre-Categories view of Mail. When you use All Mail, you’re viewing your messages without any categorization, like in List View.

Satellite features for all iPhone 13 models

Apple’s iOS 18.5 also brings certain satellite features, like messaging, to the iPhone 13 lineup. That means if you go off the grid, you could still text people to let them know where you are. However, these features on iPhone 13 models are carrier dependent, and currently only T-Mobile offers them in the US via Starlink

T-Mobile Starlink is in beta, and the beta is free and open to anyone until July, including people on other carrier plans. After July, it will be part of the T-Mobile Experience Beyond and Go5G Next plans. People with other carriers, like Verizon and AT&T, will then be able to access the system for $10 a month. 

Back Tap banner

The iOS 18.5 update also introduces the option to display a banner using the Back Tap function. Back Tap turns the Apple logo on the back of your iPhone into a usable button that can open your camera, take a screenshot and more when you double- or triple-tap it. And with iOS 18.5, you can make your iPhone display a banner whenever you use Back Tap.

To enable the banner, go to Settings > Accessibility > Touch > Back Tap and tap the toggle next to Show Banner. If you enable the banner and use Back Tap, the banner will appear across the top of your screen and read, «Back Tap Double/Triple Tap detected.»

iOS 18.5 release notes

Here are the full release notes for iOS 18.5.

This update also includes the following enhancements and bug fixes:

  • A new Pride Harmony wallpaper.
  • Parents now receive a notification when the Screen Time passcode is used on a child’s device.
  • Buy with iPhone is available when purchasing content within the Apple TV app on a third-party device.
  • Fixes an issue where the Apple Vision Pro app may display a black screen.
  • Support for carrier-provided satellite features is available on iPhone 13 (all models). For more information, visit:

Some features may not be available for all regions or on all Apple devices. For information on the security content of Apple software updates, please visit:

These 10 Hacks Could Be the End of Your Terrible Signal Forever

Say goodbye to weak bars with these reception-boosting hacks.

There’s nothing worse than being in the middle of a road trip and realizing your cell signal has dropped out. No GPS, no music and no way to call for help if something goes wrong. A weak signal can cause all kinds of problems, but the good news is that there are a few quick fixes that might get you back online fast.

Whether you’re using an iPhone or Android, these simple hacks can help boost your reception and keep you connected when you need it most.

Whether you’re doing some routine phone maintenance or you’re stuck in an emergency, there are multiple ways to improve your reception on an iPhone or Android phone, no matter what type of phone plan you’re on. It might even come down to something as simple as toggling Airplane mode. 

To go from dropped calls to full bars, here’s what you need to know.

Note: Although software across different iPhone models is relatively the same, Samsung Galaxy, Google Pixel and other Android phones may have different software versions, so certain settings and where they are located might differ depending on device.

For more, check out how you can use Google Maps when you’re offline and how you can maybe fix your internet when it’s down.

To improve your cellphone service, try these steps first

The settings on your phone can help you get better cell service, but there are other tricks for improving your reception without even touching your phone’s software.

  • Move yourself so that there are no obstructions between your phone and any cell towers outside. That might involve stepping away from metal objects or concrete walls, which both kill reception. Instead, get to a window or go outside if possible.
  • Remove your phone case. It doesn’t hurt to remove whatever case you have on your phone, especially if it’s thick, so that the phone’s antenna isn’t blocked by anything and can get a better signal.
  • Make sure your phone is charged. Searching for and connecting to a stronger signal drains power, so if your phone battery is already low on charge, you may have a difficult time getting good service.

Always start by turning Airplane mode on and off

Turning your phone’s connection off and then back on is the quickest and easiest way to try and fix your signal woes. If you’re moving around from one location to another, toggling Airplane mode restarts the Wi-Fi, Bluetooth and cellular network modems, which forces them to find the best signal in the area.

Android: Swipe down from the top of your screen — to access the Quick Settings panel — and then tap the Airplane mode icon. Wait for your phone to completely disconnect from its Wi-Fi and cellular connections. It doesn’t happen instantly, so give it a good 15 seconds before you tap on the Airplane mode icon again.

iPhone: On the iPhone, you can access Airplane mode from the Control Center, but that varies depending on which iPhone model you have. On the iPhone X and later, swipe down from the top-right corner to access the Control Center. On older iPhone models, swipe up from the bottom of the screen. Then tap the Airplane mode icon, which will turn orange when it’s enabled. Again, wait up to 15 seconds before turning it off.

If Airplane mode doesn’t work, restart your phone

Our phones are miniature computers, and just like computers, sometimes you can fix issues like network connection by simply restarting them.

Android: Hold down the power button, or the power button and the volume down key (depending on your Android phone), until the on-screen menu shows up, and then tap Restart. If your phone doesn’t offer a restart option, you can simply tap Power Off to shut down your device, and then boot it back up with the power button.

iPhone: On the iPhone X and older models, hold down the sleep/wake button and either one of the volume buttons and then swipe right on the power slider to turn off the device. Wait until it fully turns off, then press down on the sleep/wake button to turn it back on. 

Alternatively, you can do a force reset on your iPhone: Press the volume up button, followed by the volume down button and then press and hold the side button. Keep holding it in, after your phone’s screen goes black and until you see the Apple logo appear again. 

If your iPhone has a home button, hold down the sleep/wake button until the power slider is displayed and then drag the slider to the right. Once the device is turned off, press and hold the sleep/wake button until you see the Apple logo. 

Older phone? Take your SIM card out

Another troubleshooting step that might help is to remove your SIM card, if your phone has one, and then place it back in with the phone turned on. If the SIM card is dirty, clean it. If it has any physical defects, you may need to replace it.

You’ll need a SIM card tool — usually included in your phone’s box — or an unfolded paper clip or sewing needle to get the SIM tray out of your phone.

All phones: Remove the SIM card, check to see if it’s damaged and positioned in the SIM tray correctly, then put it back in your phone.

eSIM: For phones with an eSIM — that is, an embedded electronic SIM in your phone — there’s nothing for you to remove. The best you can do is restart your phone.

Check your carrier settings (and update your software)

Mobile carriers frequently send out carrier settings updates to help improve connectivity for calls, data and messages on their network. Although this feature is available on all iPhone models, it’s not universal on Android, so you might not find carrier settings if you don’t have a supported phone.

iPhone: Carrier updates should just appear, and you can update from the pop-up message that appears. To force your iPhone to check for a carrier settings update, go to Settings > General > About on your phone. If an update is available, you’ll be prompted to install it.

Android: As mentioned before, not all Android phones have carrier settings, so you’ll have to open the Settings app and type in «carrier settings» to find any possible updates. On supported Pixels, go to Settings > Network & internet > Internet, tap the gear next to your carrier name and then tap Carrier settings versions.

Reset your phone’s network settings

Sometimes all you need is a clean slate to fix an annoying connectivity issue. Refreshing your phone’s network settings is one way to do that. But be forewarned, resetting your network settings will also reset any saved Wi-Fi passwords, VPN connections and custom APN settings for those on carriers that require additional setup.

Android: In the Settings app, search for «reset» or more specifically «reset network settings» and tap on the setting. On the Pixel, the setting is called Reset Wi-Fi, mobile & Bluetooth. After you reset your network settings, remember to reconnect your phone to your home and work Wi-Fi networks.

iPhone: Go to Settings > Transfer or Reset iPhone > Reset > Reset Network settings. The next page will warn you that resetting your network settings will reset your settings for Wi-Fi, mobile data and Bluetooth. Tap Reset Network Settings and your phone will restart.

Contact your phone carrier

Sometimes unexpected signal issues can be traced back to problems with your wireless carrier. A cell tower could be down, or the tower’s fiber optic cable could have been cut, causing an outage.

For consistent problems connecting to or staying connected to a cellular or data network, it’s possible your carrier’s coverage doesn’t extend well into your neighborhood. 

Other times, a newfound signal issue can be due to a defect with your phone or a SIM card that’s gone bad. Contacting your carrier to begin troubleshooting after you’ve tried these fixes is the next best step to resolving your spotty signal.

If all else fails, try a signal booster to improve cell reception

If after going through all of our troubleshooting steps, including talking to your carrier to go over your options, you’re still struggling to keep a good signal — try a booster. A signal booster receives the same cellular signal your carrier uses, then amplifies it just enough to provide coverage in a room or your entire house. 

The big downside here is the cost. Wilson has three different boosters designed for home use, ranging in price from $349 for single room coverage to $999 to cover your entire home. To be clear, we haven’t specifically tested these models. Wilson offers a 30-day money-back guarantee and a two-year warranty should you have any trouble with its products.
