In 2024, comparing the iPhone 8 and Galaxy S9 isn’t just a nostalgic trip—it’s a practical question for users holding onto aging but once-flagship devices. Both launched in 2017 and 2018 respectively, these phones were powerhouses in their time. But nearly seven years later, how do they stack up against modern expectations? More importantly, if you're still using one, is upgrading truly necessary or even beneficial?
The answer isn't a simple yes or no. It depends on your usage patterns, software needs, and what you expect from a smartphone today. While neither device supports the latest features like 5G or advanced AI photography, they may still serve light users adequately. However, critical factors like security updates, app compatibility, and performance under modern workloads have shifted dramatically.
Performance and Hardware in 2024
The iPhone 8 runs Apple’s A11 Bionic chip, while the Galaxy S9 uses either the Snapdragon 845 (U.S.) or Exynos 9810 (international). At launch, both chips delivered smooth multitasking and excellent gaming performance. Today, however, their limitations are evident.
Modern apps—especially social media platforms, video editors, and web browsers—are more demanding than ever. Background processes, high-resolution assets, and JavaScript-heavy websites strain older processors. The A11 can struggle with tab-heavy Safari sessions, and the S9 often lags when switching between apps or loading large images.
Battery health is another major concern. After six to seven years, most original batteries have degraded to 60–70% capacity. Even with replacements, thermal throttling and inconsistent charging behavior are common. Neither phone supports fast charging beyond modest speeds (iPhone 8: 18W max with adapter; S9: 15W via Adaptive Fast Charging), making full charges a lengthy process.
“Devices from this era weren’t designed for long-term software bloat. What ran smoothly in 2018 now feels sluggish because the ecosystem evolved faster than hardware longevity.” — David Lin, Mobile Systems Analyst at TechLongevity Labs
Software Support and Security
This is where the real divergence occurs. Apple continues to support the iPhone 8 with iOS updates—iOS 17, released in 2023, remains compatible. That means access to current security patches, privacy features, and basic functionality improvements. However, iOS 18, expected in mid-2024, will likely drop support for the iPhone 8, marking the end of its update lifecycle.
Samsung, on the other hand, ended official Android version updates for the Galaxy S9 after Android 10. Security patches ceased entirely by 2021. This means the S9 runs outdated software vulnerable to known exploits. Many modern apps—including banking, messaging, and productivity tools—either refuse to install or function poorly due to deprecated APIs.
Camera and Multimedia Capabilities
Photography has advanced significantly since 2018. The iPhone 8 features a single 12MP rear camera without Night mode, Deep Fusion, or Smart HDR. The Galaxy S9 also has a 12MP sensor but includes variable aperture (f/1.5–f/2.4) and superior low-light processing for its time.
In daylight, both cameras produce acceptable results for casual snaps. But in dim lighting, grain, blur, and poor dynamic range become apparent. Video recording caps at 4K@60fps on the iPhone 8 and 4K@30fps on the S9—technically capable, but lacking stabilization and audio optimization found in newer models.
For social media use, especially platforms relying on vertical video (TikTok, Instagram Reels), these phones fall short. Lack of front-facing stabilization, slow autofocus, and limited editing tools make content creation frustrating.

Real-World Example: Sarah’s Dilemma
Sarah, a freelance writer in Portland, has used her iPhone 8 since 2018. She values simplicity and avoids frequent upgrades. In early 2024, she noticed her banking app crashing repeatedly, and Zoom calls started freezing during client meetings. Her email took over 30 seconds to load new messages.
She visited a local repair shop, where diagnostics showed 68% battery health and insufficient storage (only 12GB free on 64GB model). The technician explained that iOS 17 was running inefficiently on aging hardware and recommended either a battery replacement plus factory reset or upgrading to an iPhone SE (2022) for $429.
Sarah chose the upgrade. The difference was immediate: faster app launches, reliable FaceTime, and better keyboard responsiveness. “I didn’t realize how much mental fatigue came from waiting for my phone,” she said. “The new one just works.”
Step-by-Step: Should You Upgrade?
- Evaluate daily pain points: Do apps crash? Is typing delayed? Does the battery die before noon?
- Check software status: Is your device receiving security updates? Can it run current versions of essential apps?
- Assess battery health: On iPhone, go to Settings > Battery > Battery Health. Below 80% indicates degradation. On Android, use diagnostic codes (*#*#4636#*#*) or third-party apps.
- Test core functions: Try loading a 10-tab browser session, sending a photo via WhatsApp, and starting a 10-minute video call.
- Consider cost of repair vs. replacement: A new battery costs $50–$80. If combined fixes exceed $100, upgrading may offer better long-term value.
When Sticking With Your Old Phone Makes Sense
Not everyone needs a new phone. Some users thrive on minimalism. If you only use your device for calls, texts, podcasts, and occasional web browsing, both the iPhone 8 and S9 can last longer—especially with a battery replacement.
Secondary devices are another valid use case. Many people repurpose old phones as dedicated music players, smart home controllers, or dashcams. In such roles, outdated specs matter less.
FAQ
Can the iPhone 8 run iOS 17 smoothly?
It can run iOS 17, but performance varies. Users report slower app launches, occasional freezes, and reduced battery life. Heavy multitaskers will notice significant lag.
Is the Galaxy S9 still safe to use in 2024?
Not recommended for sensitive tasks. Without security updates, it's vulnerable to malware and phishing attacks, especially when downloading files or logging into accounts.
What’s the cheapest worthwhile upgrade from these models?
The iPhone SE (2022 or 2023) offers modern performance in a similar form factor. For Android, the Google Pixel 7a or Samsung Galaxy A54 provide updated software, better cameras, and five years of support.
Final Verdict: Time to Move On
In 2024, continuing to rely on the iPhone 8 or Galaxy S9 as a primary device comes with growing compromises. While the iPhone 8 benefits from Apple’s extended support, it’s nearing the end of its lifecycle. The Galaxy S9, meanwhile, operates on obsolete software with known vulnerabilities.
Upgrading isn’t about chasing the latest trends—it’s about maintaining reliability, security, and efficiency. Modern budget phones outperform these legacy devices in every meaningful way: faster processors, larger batteries, improved displays, and ongoing updates.
If your phone causes daily frustration, interrupts work, or puts your data at risk, then yes—it’s absolutely worth upgrading. The investment pays back in time saved, stress reduced, and peace of mind gained.
