Galaxy S23 battery life: Does it last longer than the Galaxy S22? End-shutdown

This story is part of Samsung EventsCNET’s collection of news, tips and advice on the most popular Samsung products.

My biggest complaint about the past year Galaxy S22 so your battery didn’t last long enough on a single charge. Fortunately, Samsung has addressed that shortcoming with the recently released Galaxy S23which includes a larger battery and a more energy efficient processor.

he Galaxy S23 It doesn’t offer record-breaking battery life, but it’s enough of an improvement that I’m comfortable using it on a busy day without lugging around a charger. That’s more than I could say for the Galaxy S22, which left me with battery anxiety in long days spent away from an electrical outlet.

Small Android phones like the Galaxy S23 and Galaxy S22 it can be hard to come by, so I’m glad Samsung made this fix on its flagship 6.1-inch phone.

The bigger battery of the Galaxy S23 makes all the difference

samsung increased the battery capacity of the Galaxy S23 by 200 mAh compared to the Galaxy S22. The new phone has a 3900 mAh battery, while last year’s device has a 3700 mAh capacity. But that’s not the only factor influencing battery life.

The Galaxy S23 family runs on a version of Qualcomm Snapdragon 8 Gen 2 Processor optimized specifically for the Galaxy S23 series. Samsung says this new processor provides better power efficiency, which contributes to longer battery life for the phone.

Even after spending only a short time with the Galaxy S23, these changes are noticeable. The Galaxy S22’s battery would sometimes drop to the low 30s or 40s around 9pm after a long day at 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 through the night. (I usually had the always-on display turned off and the refresh rate set to standard instead of adaptive.)

Fortunately, my experience with the Galaxy S23 has been very different so far. I still had 64% battery left at 12:36am on a recent Sunday when I unplugged the phone from the charger at 10am that morning. However, it’s important to note that I wasn’t using my phone very often that afternoon either. I spent time with my family for much of the day, so I mostly kept my phone tucked away in my pocket, only retrieving it to check my texts or take a picture from time to time.

But even on a busy day, the Galaxy S23 still had more battery left than the Galaxy S22 likely would. After a day of running benchmarks, taking lots of photos, shooting videos, and streaming YouTube videos as part of my review test, I still had 46% battery left at 9:45 p.m. That’s not too bad if you consider the Galaxy S22 sometimes. it had about 30-40% of its battery left around 9pm after using the phone a lot all day. I also left the adaptive refresh rate setting on for most of my time with the Galaxy S23.

To further test the battery, I put each phone through a 45-minute endurance test and a three-hour battery discharge test. During the 45-minute test, I continuously streamed videos on YouTube, made a video call, played mobile games, and scrolled through social media to see what a toll these everyday tasks would take on each phone’s battery. For the three-hour test, I streamed YouTube with the screen brightness set to 100% and checked the battery percentage once an 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.

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 affect battery life, so your experience may not be exactly the same as mine. For example, while I sometimes struggled to get through an entire day using the Galaxy S22, I was able to conserve roughly 60-70% of my battery at 9pm with the always-on display off on days I spent most of my time at home. .

If you own a Galaxy S22 and are experiencing battery life issues, there are a few steps you can take to maximize the life of your device. First, try lowering the screen brightness by pulling down from the top of the screen to access your phone’s quick settings menu.

You’ll also want to make sure the adaptive brightness setting is turned off to prevent your phone from automatically increasing the brightness when needed. While that can be a useful feature under normal circumstances, you might not want the brightness boosted when you’re trying to conserve battery life. Open the settings menu on your Galaxy S22, choose the display option, and make sure the switch next to adaptive brightness is turned off.

It’s also a good idea to try turning off the adaptive refresh rate and always-on display setting if you’re trying to extend battery life, which you can toggle in the settings menu.

Samsung devices have a power saving mode that disables certain settings to make the battery last longer. Open the settings menu, select the device and battery care option, and then touch the battery to access it. From this battery menu, you can also limit battery usage for apps you don’t use very often.

These tips will also work on the Galaxy S23, 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 & 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 buying a portable charger or power bank to turn on your device on the go.

At its new price of $700, the Galaxy S22 is a tempting option alongside the $800 Galaxy S23. Just remember that you’ll be sacrificing some battery life to get that cheaper price.
