The Galaxy S23 It doesn’t offer record-breaking battery life, but it’s enough of an improvement to make me comfortable using it on a busy day without carrying the charger. That’s more than I can say for the Galaxy S22 Battery worries leave me Long days away from the power station.

Small Android phones like Galaxy S23 and Galaxy S22 It can be hard to come by, which is why I’m glad Samsung did it with its 6.1-inch flagship phone.

The Galaxy S23 family runs on one version Qualcomm’s Snapdragon 8 Gen 2 An optimized processor especially for the Galaxy S23 series. Samsung claims this new processor brings better power efficiency, which contributes to the phone’s longer battery life.

Even after spending some time with the Galaxy S23, these changes are noticeable. The Galaxy S22’s battery sometimes drops to the 30s or 40s by 9pm after a long day at the office. I once had to borrow a co-worker’s charger while attending an all-day work event because I was worried I wouldn’t make it to the evening. (Always on display turned off and I set the refresh rate to constant instead of adaptive).

My experience with the Galaxy S23 has thankfully been very different so far. When I took the phone off the charger at 10 a.m. on a recent Sunday, it had 64% battery left at 12:36 p.m. However, it should be noted that I didn’t use my phone very often that afternoon. I was spending time with my family throughout the day, so I mostly kept my phone in my pocket, only occasionally pulling it out to check my texts or take a photo.

But even on a busy day, the Galaxy S23 outlasts the Galaxy S22’s battery. After a day of running benchmarks, taking lots of photos, recording videos and streaming YouTube videos as part of my review test, I still had 46% of my battery left at 9:45pm, which isn’t so bad when you consider the Galaxy S22 at times. . By 9pm after using the phone heavily throughout the day its battery had 30% to 40% left. I also had the Adaptive Refresh Rate setting turned 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 drain test. During the 45-minute test, I continuously streamed videos on YouTube, made video calls, played mobile games and scrolled through social media feeds to see how much these everyday tasks would take a toll on each phone’s battery. For the three-hour test, I streamed YouTube with 100% display brightness and checked the battery percentage every hour to see how much it drained.

Unsurprisingly, the Galaxy S23 beats the Galaxy S22 in both tests, as you can see in the table 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 use can affect battery life, so your experience may not directly reflect mine.
