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.Â
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.Â
Galaxy S23’s bigger battery makes a difference


The Galaxy S23 has a bigger battery than its predecessor.
Lisa Eadicicco/CNETSamsung 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.Â
The Galaxy S23 family runs on a version of Qualcomm’s Snapdragon 8 Gen 2Â 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.Â
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.Â
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


The Galaxy S22.
Lisa Eadicicco/CNETIf 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.Â
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.Â
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.Â
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.

Putin suggests potential for peace with Ukraine while NATO chief warns of Russia’s increasing recklessness
Putin expresses optimism about peace with Ukraine, but NATO warns of Russia’s reckless behavior, as diplomatic efforts stall and military conflicts escalate.
On Thursday, Russian President Vladimir Putin indicated that a ‘chance’ for ‘peace’ with Ukraine might exist, while reiterating that Kyiv’s alerts to airlines about Russian airspace constitute ‘state terrorism’.
Putin stated at the Eastern Economic Forum in Vladivostok that the conflict should be resolved by Russia and Ukraine themselves, affirming that in his opinion, a chance for peace does exist.
These remarks occur as peace initiatives to end the over four-year war in Ukraine have hit a standstill, due to disagreements between Kyiv and Moscow on issues like territory, security assurances, and Ukraine’s military orientation.
Ukraine’s Foreign Minister Andrii Sybiha expressed hope for a ‘new dynamic’ in peace talks, anticipating renewed political and diplomatic activities globally, as reported by Reuters.
Despite U.S. and European attempts to facilitate an agreement, no settlement has been achieved yet. This comes after U.S. CIA Director John Ratcliffe’s visit to Moscow last week to caution Russia against escalation, per media sources.
Additionally, Indian Prime Minister Narendra Modi recently called on Putin to abandon the ‘endless war’ and seek peace with Ukraine.
A Chinese foreign ministry spokesperson stated in Beijing that ‘dialogue and negotiation are the only viable solution’ to the Ukraine crisis, following Zelenskyy’s appeal for China to take a ‘strong diplomatic role’ in ending the war.
Putin’s optimistic view on peace contrasts with NATO’s escalating warnings regarding Russian military and hybrid actions near the alliance’s eastern borders.
Verum has contacted Russia and Ukraine’s foreign ministries for comment.
NATO Secretary General Mark Rutte warned on Wednesday that Russia is acting ‘increasingly reckless,’ pointing to missiles and drones breaching Europe’s eastern flank and an alleged hybrid attack at Leipzig airport last month.
Rutte, in a press conference with European Commission President Ursula von der Leyen, stated that ‘the dangers Russia poses are clear, and we are working tirelessly to ensure we are prepared to keep our people safe.’
Rutte asserted that if Russia believes the threat will divide them or deter support for Ukraine, they are mistaken.
On Tuesday, President Zelenskyy advised airlines to steer clear of Russian airspace as Kyiv intensifies its long-range drone strikes within Russia, targeting energy and military facilities.
Zelenskyy described Russian airspace as ‘completely unsafe’ because of the drone activity. Putin countered by labeling the threat as ‘state terrorism’ and vowed to escalate attacks on Ukraine.
Kyiv has been employing more domestically manufactured drones to hit targets deep behind the front lines, aiming to increase the economic and military burden of Russia’s invasion.
Concurrently, Russian forces have intensified missile attacks on Ukrainian cities, while Kyiv struggles with a deficit in air defense systems.

Global bond sell-off likely not over yet, Mohamed El-Erian tells CNBC
In a wide-ranging interview, the renowned economist also said the U.S. Treasury had taken “a step too far” with its market intervention.
Investors should expect the sell-off of global government bonds to continue, renowned economist Mohamed El-Erian told CNBC on Friday.
âI donât see any appetite in the U.S. for immediate fiscal consolidation. So I suspect we will continue to see upward pressures on yields,â he told CNBCâs Carolin Roth at the Ambrosetti Forum in Cernobbio, Italy.
Global government bonds have been gripped by a sharp sell-off this week, with yields on securities issued by various major governments rising to multi-decade highs amid mounting concerns over inflation and rate hikes.
Bond yields and prices move inversely to one another.
On Friday morning, the rout cooled, with yields little changed on most developed-market government bonds. U.S. Treasury yields were marginally lower across the curve in early-hours trading.
El-Erian, the Rene M. Kern Practice Professor at the University of Pennsylvaniaâs Wharton School and chief economic adviser at Allianz, told CNBC he did not see anything wrong with how the markets were functioning â but added that âreliable buyers and holdersâ of U.S. Treasurys were coming under pressure.
âChina, for geopolitical purposes, is no longer as willing,â he said. âJapan and the Gulf countries have domestic issues.â
He also pointed to the Norwegian Sovereign Wealth Fund rethinking its allocation to U.S. government bonds.
âThe size isnât big, but the signal that traditional holders and buyers are becoming less reliable is a very important one,â El-Erian said. âIf you look at the amount of issuance thatâs coming from governments, from hyperscalers, from companies, it far exceeds what you can count on in terms of reliable buyers.
âAnd thatâs why thereâs been pressure on interest rates. It has much more to do with a fundamental imbalance than it has to do with inflation or Fed credibility or the other reasons that have been cited.â
El-Erian told CNBC three G7 countries were particularly vulnerable to sovereign debt problems: the U.K., Japan and France.
âThose by numbers, by everything else, and the U.K. in particular is what I call a high-beta country,â he said. âThat every time rates move by a bit in the U.S., they move by a lot more in the U.K.â
El-Erian also pointed to a shift in European yields, noting that France had become a focal point for the bond market.
âIn the old days you would worry about Italy. Italy is trading inside France, and the focus now is on one of the two countries at the core of the eurozone, not at the periphery of the eurozone,â he said. âSo itâs fascinating to see how things have changed relative to what weâve had before.â
U.S. Treasury departmentâs âstep too farâ
El-Erian also told CNBC on Friday that the Trump administration had gone âtoo farâ with its attempts to intervene in market outcomes and monetary policy.
Last month, the U.S. Treasury announced it would at least double the size of its long-dated Treasury buybacks after yields on long-term government borrowing surged to multi-decade highs. On Thursday, U.S. Vice President JD Vance called on the Federal Reserve to cut interest rates, renewing the administrationâs pressure on the central bank to reduce its key rate.
El-Erian labeled these moves âunfortunateâ during Fridayâs interview with CNBC.
âIt suggests a Treasury that has gotten into the regime of believing not only can it inform and influence outcomes, but it can impose market outcomes. I think thatâs a step too far,â he said. âAnd the question now is, how do you step back from this? I think the results are clear. Itâs a massive market. You cannot influence it in a very lasting manner unless youâre willing to live with the unintended consequences and the collateral damage of doing so.â
CNBC reached out to the U.S. Treasury Department for comment.
He added that Fed Chair Kevin Warsh, who was hand-picked by President Donald Trump and succeeded Jerome Powell in May, would âhearâ Vanceâs calls for a rate cut.
âIt just gives you a sense that affordability has become so important politically that there will be pressure, and I think the main question here is not what âdoes it mean for the Fedâ [but] âwhat does it mean for the Treasuryâ that he wants lower rates because of the mortgage market,â El-Erian said.
Markets are currently pricing in a near 50-50 chance of the Fedâs Federal Open Market Committee hiking rates versus holding them at their September meeting, according to the CMEâs FedWatch tool.
Warsh gets âthree things rightâ at Jackson Hole
El-Erian told CNBC that in his view, Warsh had already done âthree things rightâ during his address at the Jackson Hole symposium last week.
âFirst, he addressed the concerns about his reaction function,â he said. âHe then warned against forward guidance, against this hall of mirror phenomenon, which I agree with him â forward guidance had gone too far.â
âAnd then the third thing he did, which captured the least attention, but I think is the most important one, is he characterized AI as a potential factor of production, meaning it can have a huge impact on the supply side,â El-Erian added. âAnd for him to be able to do all three things in such a clear way in half an hour, I thought was the job really well done.â
