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.

Meta’s New AI Model Is Reportedly Delayed Again. Is ‘Avocado’ Toast?

Avocado, code name of Meta’s next-generation foundational AI model, might not be released until May.

Meta’s Avocado isn’t ripe quite yet. The company has reportedly delayed the release of its next-generation foundational model until May, according to The New York Times, citing unnamed sources. The model has fallen short «on internal tests for reasoning, coding and writing,» compared with rival models from Google, OpenAI and Anthropic.

Meta has spent billions of dollars overhauling its efforts to build artificial intelligence models and products, including purchasing a stake in Alexandr Wang’s startup for $14.3 billion to make him chief AI officer. The company has poured buckets of cash into hiring top AI engineers last year across its organization. In a January earnings call, Meta confirmed it plans to raise its spending from $72 billion last year to $115 billion to $135 billion, attributing the increase to supporting its AI labs. But all that money hasn’t bought the company the results it hoped for, with Google, OpenAI and Anthropic consistently lapping Meta with their newer models.

A Meta spokesperson told CNET, «As we’ve said publicly, our next model will be good, but more importantly, show the rapid trajectory we’re on, and then we’ll steadily push the frontier over the course of the year as we continue to release new models. We’re excited for people to see what we’ve been cooking very soon.»

That rapid trajectory is key to catch up and keep pace with other AI builders. Google leapfrogged its rivals in November with its Gemini 3 model, showcasing its impressive coding and research abilities. OpenAI was quick to follow with updates to GPT-5. More recently, Claude Code and Cowork from Anthropic have proven to be the most reliable agentic AI available, tools that can handle tasks without human babysitting. However, the biggest AI news from Meta this year is that it’s buying Moltbook, a social media platform designed exclusively for AI bots.

Meta has been in the news for other reasons. A renewed wave of privacy concerns has crested over people using smart glasses, particularly the Meta Ray-Ban glasses, to record others without their knowledge or consent. A lawsuit alleges that human staffers behind Meta’s smart glasses reviewed footage of people who clearly didn’t know they were being recorded, like while they were undressing or having sex. On the social media side of the business, a high-profile trial is debating whether platforms like Meta’s Instagram and Facebook are addictive to teens and pose significant health risks.

AI-Recommended Music? Spotify Is Giving You the Power to Personalize

On stage at SXSW, Spotify Co-CEO Gustav Söderström announced a new feature that lets you shape your own Taste Profile.

A new Spotify feature promises to let you review and customize your Taste profile, Co-CEO Gustav Söderström announced during a session at South by Southwest Friday.

Right now, Spotify’s Taste Profile is AI-driven based on your listening habits, history and song preferences. The in-app AI analyzes what you skip, play, repeat, revisit and save to personalize the recommendations you see in Discover Weekly, Daily Mixes and Wrapped playlists. But this new feature is giving you, the listener, the power to shape what you see. 

This feature is currently in beta and will begin rolling out first to listeners in New Zealand in the coming weeks. 

Fine-tune your Taste

With this feature, Spotify is taking you under the hood to show you how the app understands your music taste. Then you can edit it for yourself to mold what you’re recommended on Spotify’s homepage. 

Want to listen to more Justin Bieber? You can ask for more. Want less house music added to your recommended playlists? Ask for less. 

You can also tell the app what genres and artists you’re in the mood for, or if there’s a certain vibe you’re looking to curate. 

Over time, your input will fine-tune your music recommendations, so what gets prioritized, queued and discovered on Home is curated with your help.
