Upgrading From S9 To S20 Is The New Samsung Really Worth It

For long-time Galaxy S9 users, the decision to upgrade isn’t just about wanting a newer model—it’s about whether the improvements deliver meaningful value. The jump from the Galaxy S9, released in 2018, to the Galaxy S20, launched in 2020, spans two generations of Samsung’s flagship evolution. While the S20 is no longer the latest model, many users still consider it a viable upgrade path due to its availability on the secondary market and solid software support. But does the performance, design, and feature set justify leaving behind a still-functional S9?

The answer depends on your usage patterns, expectations, and how much you value modern smartphone capabilities. Let’s break down the key differences and determine whether this upgrade truly pays off.

Design and Display: A Noticeable Leap Forward

The Galaxy S9 featured a 5.8-inch Full HD+ Super AMOLED display with a 16:9 aspect ratio—compact, balanced, and well-suited for one-handed use. In contrast, the S20 introduced a 6.2-inch Dynamic AMOLED 2X display with a 120Hz refresh rate, QHD+ resolution, and a taller 20:9 aspect ratio. This shift dramatically improves scrolling smoothness, media immersion, and multitasking efficiency.

The higher refresh rate alone transforms the user experience. Animations feel snappier, games respond faster, and general navigation gains a fluidity the S9 simply can’t match. Additionally, the S20’s flatter screen reduces glare and improves touch accuracy compared to the S9’s curved edges, which some found prone to accidental inputs.

Tip: If you frequently watch videos or scroll through social media, the S20’s 120Hz display will feel like a major quality-of-life improvement.

Performance and Hardware: Generational Gains

Under the hood, the difference is stark. The S9 ran on either the Exynos 9810 or Snapdragon 845 (depending on region), both capable chips for their time but now showing their age in multitasking and app launch speeds. The S20, however, came with the Exynos 990 or Snapdragon 865—chips built for 5G, improved AI processing, and better thermal efficiency.

Benchmarks show a 30–40% increase in CPU performance and nearly double the GPU power in the S20. Real-world usage reflects this: apps open faster, photo editing is smoother, and gaming at high settings becomes genuinely viable. The S20 also increased RAM from 4GB to 8GB (base model), allowing more background apps to stay active without reloading.

Storage options also improved, with UFS 3.0 replacing UFS 2.1, resulting in quicker file transfers and app installations. For users who rely on productivity tools, cloud sync, or mobile gaming, these upgrades are not just incremental—they’re transformative.

Camera System: From Solid to Flagship-Level

The S9 had a strong single 12MP rear camera with variable aperture (f/1.5–f/2.4), optical image stabilization, and excellent low-light performance for its era. However, the S20 expanded into multi-lens territory with a triple-camera setup: a 12MP main sensor, a 64MP telephoto lens, and a 12MP ultra-wide shooter.

This enables far greater creative flexibility. You can now shoot wide-angle landscapes, zoom in up to 3x hybrid zoom (and 30x digital with Space Zoom), and capture more dynamic compositions. Video recording jumps from 4K@30fps on the S9 to 8K@24fps on the S20—a future-proof feature even if few currently edit in 8K.

“Smartphone photography isn’t just about megapixels anymore—it’s about versatility. The S20 gives users pro-level framing options that weren’t possible two years prior.” — Lena Park, Mobile Photography Analyst

Low-light performance also benefits from larger pixel binning and improved Night Mode algorithms. While the S9 held its own in good lighting, the S20 consistently delivers sharper, more detailed images across diverse conditions.

Battery and Charging: Efficiency vs. Capacity

The S9 packed a 3,000mAh battery, adequate for light users but often requiring midday charging for heavy use. The S20 increases capacity to 4,000mAh—a 33% boost—and pairs it with more efficient hardware and adaptive refresh rate technology.

Despite the larger display and faster processor, the S20 typically lasts 30–50% longer on a single charge. Standby optimization and Doze mode enhancements further extend real-world endurance. Both phones support fast charging (15W) and wireless charging, but the S20 adds reverse wireless charging, letting you power up earbuds or another phone in a pinch.

Real-World Example: Sarah’s Upgrade Journey

Sarah had used her Galaxy S9 since 2018. By 2022, she noticed constant app reloads, sluggish camera startup, and battery anxiety by noon. She considered an iPhone but opted for a refurbished S20 after reading comparisons.

Within days, she reported that “everything just feels faster.” Scrolling through Instagram was smoother, her kids’ soccer videos looked sharper in 4K, and she could finally use split-screen apps without lag. Most importantly, the battery lasted through her workday and evening walks without needing a pack. Though she missed the S9’s compact size, the overall experience made the trade-off worthwhile.

Step-by-Step: Is the Upgrade Right for You?

1. Evaluate your current pain points: Does your S9 struggle with app switching, slow camera response, or short battery life?
2. Assess your usage: Are you a heavy multimedia consumer, photographer, or multitasker? The S20 excels in these areas.
3. Check software support: The S20 received four major Android updates (up to Android 14), while the S9 stopped at Android 11. Security patches also ended earlier for the S9.
4. Compare pricing: Refurbished S20 models range from $150–$220. Weigh this against waiting for newer models like the S23 FE or S24 series.
5. Test ergonomics: The S20 is taller and heavier. If pocketability is crucial, consider using a case or trying a demo unit.

Tip: Before upgrading, back up your S9 data via Samsung Smart Switch to ensure a seamless transfer of apps, messages, and settings.

Frequently Asked Questions

Will the S20 still receive software updates?

As of 2024, the Galaxy S20 series has reached the end of its major OS update cycle but may still receive quarterly security patches depending on your carrier and region. It supports Android 14, which ensures compatibility with most current apps.

Is the S20 waterproof like the S9?

Yes, both phones have an IP68 rating, meaning they can withstand submersion in up to 1.5 meters of water for 30 minutes. However, water resistance degrades over time, especially if the device has been repaired.

Can I expect better signal and connectivity?

The S20 supports 5G (in mmWave and sub-6 variants, depending on model), offering faster download speeds where coverage exists. Wi-Fi 6 support also improves network efficiency in crowded environments like offices or apartments.

Conclusion: Taking the Leap

Upgrading from the Galaxy S9 to the S20 isn’t just about having a newer phone—it’s about stepping into a significantly more responsive, capable, and future-ready device. The combination of a high-refresh display, superior camera system, extended battery life, and stronger performance makes the S20 a compelling upgrade for anyone still clinging to the S9.

If you're frustrated with slowdowns, limited photo options, or daily charging stress, the S20 delivers tangible improvements that enhance everyday usability. While newer models exist, the S20 strikes a sweet spot between price, performance, and longevity—especially in the refurbished market.
