Samsung A23 Vs A20 Is The Newer Model Really Worth The Upgrade

When it comes to budget smartphones, Samsung’s Galaxy A series has long been a go-to for users who want solid performance without breaking the bank. The Galaxy A20 was a popular choice in its time, offering decent features at an accessible price. Now, its successor—the Galaxy A23—has entered the market with updated hardware and software improvements. But does the newer model truly justify the upgrade? For current A20 owners or buyers on the fence, this comparison dives deep into design, performance, camera quality, battery life, and overall value to help determine whether stepping up to the A23 makes sense.

Design and Build: Subtle Evolution

The Galaxy A23 and A20 share a familiar Samsung aesthetic—plastic backs, slim bezels, and punch-hole front cameras. However, there are notable differences in build quality and ergonomics. The A23 feels slightly more refined, with a matte finish that resists fingerprints better than the glossy back of the A20. It's also marginally heavier (195g vs 169g), which gives it a more substantial feel in hand, though some may find it less comfortable for one-handed use.

Both phones feature a side-mounted fingerprint sensor integrated into the power button, but the A23 includes an improved sensor with faster response times. The A20 relies solely on face recognition and fingerprint unlocking, while the A23 benefits from firmware updates that have enhanced biometric reliability.

Tip: If you frequently use your phone outdoors, the A23’s brighter display and improved contrast make it easier to view in sunlight.

Display and Screen Experience

The screen is where one of the most noticeable upgrades occurs. The Galaxy A20 sports a 6.4-inch Super AMOLED display with a resolution of 720 x 1560 pixels. While AMOLED panels deliver deep blacks and vibrant colors, the lower resolution can make text and images appear slightly grainy up close.

In contrast, the Galaxy A23 steps up with a larger 6.6-inch PLS LCD panel, which isn’t technically AMOLED but compensates with a higher Full HD+ resolution (1080 x 2408 pixels). This means sharper visuals, crisper text, and a more immersive experience when streaming videos or browsing social media. Additionally, the A23 supports a 90Hz refresh rate—compared to the A20’s standard 60Hz—resulting in smoother scrolling and more responsive touch input.

While purists may miss the true blacks of AMOLED, the practical benefits of higher resolution and smoother motion often outweigh that drawback for everyday users.

Performance and Hardware Comparison

Under the hood, the jump from the A20 to the A23 represents a meaningful leap in processing power. The A20 runs on the Exynos 7904 chipset—an older octa-core processor built on a 14nm process—with either 3GB or 4GB of RAM. While adequate for basic tasks like calling, texting, and light app usage, it struggles with multitasking and modern apps that demand more resources.

The A23, meanwhile, uses the Qualcomm Snapdragon 680 processor—a 6nm chip with eight cores clocked up to 2.4 GHz. Paired with 4GB or 6GB of RAM, this setup delivers noticeably snappier performance. Apps launch faster, background switching is smoother, and the device handles photo editing, video calls, and casual gaming (like Candy Crush or Among Us) with greater ease.

“Even modest improvements in chipset efficiency can extend usability by 1–2 years, especially in entry-level devices.” — Raj Mehta, Mobile Hardware Analyst at TechPulse Insights

The A23 also ships with Android 12 (upgradable to Android 13 and potentially Android 14), whereas the A20 launched with Android 9 and maxes out at Android 11. This means longer software support, better security updates, and access to newer features like improved privacy controls and notification management.

Camera Capabilities: More Than Just Megapixels

On paper, both phones boast quad-camera setups, but real-world results tell a different story. The A20 features a 13MP main sensor, 5MP ultra-wide, 2MP depth, and 2MP macro lens. In practice, photos suffer from inconsistent focus, poor dynamic range, and excessive noise in low light.

The A23 improves across the board with a 50MP main sensor, 5MP ultra-wide, 2MP macro, and 2MP depth sensor. The higher-resolution primary camera captures significantly more detail, especially in daylight. Image processing is also more consistent, thanks to better stabilization and AI enhancements. Night mode is now available, allowing for brighter, clearer shots in dim environments—something the A20 lacks entirely.

The front cameras reflect a similar trend. The A20’s 8MP selfie shooter produces acceptable results in good lighting but falters indoors. The A23 bumps this up to 8MP with improved autofocus and portrait mode accuracy, making video calls and selfies more reliable.

Battery Life and Charging: Real-World Endurance

Battery capacity remains strong in both models, but efficiency gains give the A23 the edge. The A20 packs a 4000mAh battery, which typically lasts a full day with moderate use. The A23 increases this to a robust 5000mAh unit, paired with a more energy-efficient processor and OS optimizations.

In real-world testing, the A23 consistently achieves 1.5 days of mixed usage—including messaging, web browsing, music streaming, and short video sessions. Even heavy users will likely get through a full day without needing a recharge.

Charging speed is another win for the A23. It supports 25W fast charging (though often shipped with a 15W charger), reducing charge time from 0 to 100% in about 70 minutes. The A20 is limited to 15W charging, taking closer to 100 minutes for a full charge.

Real-World Example: Maria’s Upgrade Decision

Maria had used her Galaxy A20 since 2019. By 2023, she noticed constant lag when opening WhatsApp or Instagram, frequent app crashes, and a camera that no longer met her needs for posting online. After researching options, she considered buying a used iPhone SE or sticking with Samsung. She opted for the A23 after testing it in-store.

“The difference in speed was instant,” she said. “I could scroll through my feed without stuttering, take clearer photos of my kids, and even watch YouTube without the battery dying by lunchtime. For $150 more than a refurbished iPhone, I got a brand-new phone with three years of updates guaranteed. It felt like a real upgrade, not just a replacement.”

Maria’s experience reflects a broader trend: users upgrading from phones older than three years see significant quality-of-life improvements with the A23, even if the changes seem incremental on paper.

Is the A23 Worth the Upgrade? A Checklist

Before deciding, ask yourself the following:

• Does your current A20 struggle with app performance or multitasking?
• Do you want better photo quality, especially in low light?
• Are you frustrated by slow charging or daily battery anxiety?
• Do you value longer software support and security updates?
• Is a smoother, more responsive screen important for your usage?

If you answered yes to two or more, the A23 is likely a worthwhile investment. The combination of modern hardware, improved display, and extended software lifecycle offers tangible benefits over the aging A20 platform.

Frequently Asked Questions

Can the Galaxy A23 run games like PUBG Mobile smoothly?

The A23 can handle PUBG Mobile at medium settings with occasional frame drops. It won’t match high-end devices, but casual gamers will find it playable. The A20, however, struggles even at low settings due to thermal throttling and weaker GPU performance.

Does the A23 still have a headphone jack?

Yes, both the A20 and A23 include a 3.5mm headphone jack and support USB-C audio adapters.

How much more does the A23 cost compared to the A20?

At launch, the A20 started around $200; the A23 retails for approximately $250–$280 depending on configuration. Used or discounted A20 units may be cheaper, but new A23s offer better long-term value.

Final Verdict: Stepping Up Makes Sense

The Galaxy A23 isn’t a revolutionary leap over the A20, but it’s a well-rounded evolution. It addresses key pain points—sluggish performance, outdated software, mediocre cameras, and slow charging—with thoughtful upgrades that enhance daily usability. For anyone still relying on an aging A20, the move to the A23 brings noticeable improvements in responsiveness, display quality, and battery longevity.

More importantly, the A23 is built to last. With stronger hardware, longer software support, and faster charging, it’s likely to remain functional and secure for years longer than the A20 ever could. In the world of budget smartphones, that kind of future-proofing is invaluable.
