Samsung Galaxy A56 Battery Test: A Full-Day Performance Review

When it comes to smartphones, one of the most critical features for users is battery life. After all, what’s the point of having a powerful device if it can’t last through a day of intense usage? Today, we’re putting the Samsung Galaxy A56 to the test to see how well its battery holds up under demanding conditions.

I’ve been using the Galaxy A56 for a while now, and it has become my go-to smartphone. With two SIM cards active, plenty of apps installed, and heavy daily usage, it’s been a reliable companion. But the real question remains: Can the Galaxy A56 battery last a full day with advanced usage? Let’s dive into a detailed, real-world battery test to find out.

Starting the Day: A Full Charge

I kicked off the test early in the morning. After charging the Galaxy A56 overnight, I unplugged it from the charger once it hit 100%. The phone was ready for a day of action.

I had both SIM cards installed, Wi-Fi connected, Bluetooth enabled, and 120Hz refresh rate activated—all the bells and whistles turned on. This wasn’t going to be a battery-saving day; I was determined to push the phone’s limits with normal, heavy usage to simulate a power user’s routine.

I also wanted to make sure I documented everything I did with the phone throughout the day to give you a real picture of what you can expect from its battery life.

Morning Activities: Social Media and Video Streaming

By midday, it was time to check in on the phone’s battery performance. At around 1:43 PM, I looked at the stats. During the morning, I had:

• Watched 1 hour and 33 minutes of YouTube content

• Spent 14 minutes on TikTok

• Browsed Instagram for 10 minutes

• Used Google Maps for 2 minutes

Despite all this activity, the Galaxy A56 still had 78% battery remaining. That’s impressive considering the phone was on full brightness, with Wi-Fi, Bluetooth, and 120Hz refresh rate enabled, and two SIM cards active. I had also received a software update that morning, which patched the system to the latest security level.

What surprised me was how efficiently the phone handled multitasking. I didn’t close background apps or reduce settings to save power; everything was running as I usually use it.

Afternoon Tasks: Video Editing on CapCut

Later in the day, around 4 PM, I got into one of my most resource-intensive tasks: editing a video on CapCut. If you’ve ever edited videos on a smartphone, you know it can be demanding on both the CPU and battery.

I worked for over an hour, creating an edit that included multiple layers, transitions, and even 4K export settings. The phone’s performance remained solid—no crashes, no lag, though it wasn’t as smooth as Samsung’s flagship S25 series. But still, the experience was remarkably good for a mid-range device.

When I finally exported the 4K video, it took roughly 4 minutes to complete the rendering. After that entire editing session, the phone was only warm, not overheated—a testament to its cooling efficiency.

By the end of the editing session, I checked the battery: the phone was sitting at 40% remaining.

Here’s a quick breakdown of usage at this point:

• 1 hour 33 minutes YouTube

• 1 hour 1 minute CapCut video editing

• Other minor app uses like Instagram, TikTok, Maps

For a phone that had powered through heavy video editing and streaming, holding onto 40% battery at 4 PM was genuinely impressive.

Evening Use: More Social Media, Video Watching, and Night Photography

As the evening rolled in, I continued using the Galaxy A56 for more casual activities. I watched more YouTube videos to gather ideas for content, browsed Instagram and TikTok, and responded to messages on WhatsApp Business.

By 6:47 PM, the battery was down to 40%, despite more than 4 hours of screen-on time already logged. I hadn’t even gone to the gym yet—a part of my routine I wasn’t going to skip.

Later that night, I took the phone with me to the gym. I filmed some nighttime footage using the Galaxy A56’s camera, and I was pleasantly surprised by how well it performed under low light. The camera captured clear, vibrant shots even in challenging lighting, switching smoothly between ultrawide (0.5x) and 1x zoom modes.

Final Battery Check: End of the Day

At around 11:31 PM, it was finally time to call it a day and review the phone’s performance. After a full day of mixed heavy usage—including:

• Video editing and 4K export

• YouTube streaming

• Social media browsing (Instagram, TikTok)

• Messaging (WhatsApp Business)

• Gaming (about 37 minutes)

• Night photography

• Web browsing (Chrome running in background)

…the Galaxy A56’s battery had dropped to 3%.

Let’s break down the battery stats at the end of the day:

✅ 7 hours and 4 minutes screen-on time
✅ 7 hours and 14 minutes screen-off time
✅ Nearly 15 hours total battery duration

I couldn’t help but feel impressed. Despite putting the Galaxy A56 through demanding tasks, it managed to last an entire day without needing a recharge.

Real-World Takeaways: How Long Does the Galaxy A56 Battery Last?

This test wasn’t done under battery-saving settings or ideal conditions. I used the phone like any typical power user would:

• 120Hz refresh rate always on

• Dual SIM cards active

• Bluetooth connected

• Wi-Fi connected

• Background apps running

And despite all of that, the Galaxy A56 delivered 7 hours of screen-on time and 15 hours of total use before needing a charge.

That’s seriously good battery life.

If you’re someone who watches a lot of YouTube, edits videos on your phone, scrolls endlessly through social media, and needs a device that won’t die before bedtime, the Galaxy A56 has got you covered.

How Does It Compare to Other Phones?

When comparing the Galaxy A56’s battery life to flagship devices like Samsung’s S25 series or Apple’s iPhone 16, the A56 holds its own surprisingly well. Sure, it may not be as buttery smooth in UI transitions or as powerful in raw performance, but in battery endurance, it’s up there with more expensive phones.

In fact, the A56 lasted longer than some flagships under similar use, largely thanks to its efficient processor and smart power management.

The phone didn’t overheat even during 4K video rendering, and despite keeping 120Hz enabled all day, it didn’t drain battery excessively.

Should You Buy the Galaxy A56 for Its Battery?

If battery life is high on your priority list, the Samsung Galaxy A56 is an excellent choice, especially considering its price point. I found the phone selling online for as low as R$1,979 for the 256GB version, which makes it one of the best deals in its category.

Not only does it have solid battery endurance, but it also offers:

✅ A smooth 120Hz AMOLED display
✅ Capable cameras, even at night
✅ Good video editing performance
✅ Reliable multitasking with two SIMs active
✅ Samsung’s reliable software updates

If your daily usage includes content creation, social media management, gaming, or video streaming, the Galaxy A56’s battery can easily support you from morning till night.

Final Verdict: Galaxy A56 Battery Test Results

After spending an entire day pushing the Galaxy A56 to its limits, here’s my honest verdict:

⭐ Battery life: Excellent (7+ hours screen-on time, full-day use)
⭐ Performance: Solid for mid-range, handles video editing, gaming, multitasking
⭐ Camera: Better than expected for low-light and daytime shots
⭐ Heat management: No overheating, only mild warmth under stress
⭐ Price-to-performance: Outstanding at under R$2,000

Whether you’re a casual user or a power user, the Galaxy A56’s battery can meet your needs without requiring mid-day charging breaks.

If you’ve been considering this phone, I hope this detailed battery test helps you make an informed decision.
