For years, the iPhone 8 Plus has been a reliable workhorse—durable, familiar, and surprisingly capable. But as we move into 2025, Apple’s ecosystem has evolved dramatically. The iPhone 13, released just a few generations ago, now represents a significant leap in technology. If you're still holding onto your iPhone 8 Plus, the question isn’t just about new features—it’s about whether those upgrades translate into meaningful improvements for your daily life.
This isn’t a simple “newer is better” decision. It’s about value, longevity, usability, and whether the investment makes sense for how you use your phone today—and how you’ll use it over the next few years.
Performance: A Night-and-Day Difference
The most immediate difference between the iPhone 13 and iPhone 8 Plus lies under the hood. The iPhone 8 Plus runs on the A11 Bionic chip, a solid performer in its time. But by 2025 standards, it struggles with multitasking, app loading times, and even basic animations in newer iOS versions.
In contrast, the iPhone 13 features the A15 Bionic chip—one of Apple’s most efficient and powerful processors. It handles intensive tasks like video editing, AR apps, and gaming with ease. Apps launch faster, background processes are smoother, and the overall user experience feels modern and responsive.
More importantly, the A15 chip ensures longer software support. As of 2025, the iPhone 13 is expected to receive updates through at least 2027, while the iPhone 8 Plus stopped receiving major iOS updates after iOS 16. That means no new security patches, feature enhancements, or compatibility with future apps.
Camera Capabilities: From Good to Exceptional
The iPhone 8 Plus was one of the first iPhones to feature a dual-camera system—12MP wide and 12MP telephoto—with Portrait Mode and optical zoom. For its era, it delivered excellent photos, especially in daylight.
The iPhone 13 improves on every front. Its dual-camera setup includes a wider f/1.6 aperture for better low-light performance, sensor-shift stabilization (previously reserved for Pro models), and advanced computational photography. Features like Smart HDR 4, Photographic Styles, and Night mode on both rear cameras make a tangible difference in image quality.
Video recording sees an even greater leap. The iPhone 13 supports Dolby Vision HDR recording up to 4K at 60fps—a feature absent on the 8 Plus. If you record videos regularly, whether for social media or family memories, the dynamic range, color accuracy, and stabilization are incomparable.
“Smartphone photography isn’t just about megapixels anymore. It’s about how the hardware and software work together to capture moments naturally.” — David Lin, Mobile Photography Analyst at TechLens Weekly
Battery Life and Charging: Practical Longevity Matters
Apple never officially disclosed battery capacity for the iPhone 8 Plus, but real-world usage showed it could last a full day with moderate use. By 2025, however, battery degradation is almost certain in devices from 2017. Even with a replacement battery, efficiency drops due to aging components.
The iPhone 13 offers up to 19 hours of video playback, compared to the 8 Plus’s 14 hours. In practical terms, that often translates to one extra charge-free day per week. More importantly, the iPhone 13 supports MagSafe and Qi wireless charging, offering flexibility the 8 Plus lacks.
It also charges faster with a compatible adapter (though none included in-box). With a 20W+ USB-C charger, you can reach 50% in about 30 minutes—something the older Lightning port on the 8 Plus cannot match without third-party optimizations.
Display and Design: Modern Ergonomics vs. Familiarity
The iPhone 8 Plus sports a 5.5-inch LCD Retina HD display with wide color support and True Tone. While sharp for its time, it’s noticeably dimmer and less vibrant than the iPhone 13’s 6.1-inch Super Retina XDR OLED display. OLED delivers deeper blacks, higher contrast, and better outdoor visibility.
Design-wise, the shift may be the biggest adjustment. The iPhone 8 Plus uses Touch ID and a home button, which some users still prefer. The iPhone 13 adopts Face ID and a notch-centric design with edge-to-edge glass. There’s no physical home button—navigation is gesture-based.
If you rely heavily on Touch ID (e.g., wearing masks or using gloves), this change might feel inconvenient at first. However, Face ID in the iPhone 13 is significantly faster and more reliable than earlier versions, working even with partial face coverage in iOS 17 and later.

Real-World Example: Sarah’s Upgrade Journey
Sarah, a freelance photographer and part-time educator, held onto her iPhone 8 Plus for six years. She replaced the battery twice and managed app usage carefully. But by early 2024, she noticed issues: Instagram crashed during uploads, Zoom calls lagged, and her edited photos wouldn’t export smoothly.
She upgraded to a used iPhone 13 in March 2024. Within days, she noticed faster iCloud syncing, seamless 4K video exports, and improved low-light shots for client previews. Most importantly, her device stayed cool and responsive during back-to-back video calls—something the 8 Plus struggled with.
“I didn’t realize how much mental load my old phone added,” she said. “Waiting for things to load, restarting apps, worrying about storage—I didn’t miss it until it was gone.”
Step-by-Step: How to Decide If You Should Upgrade
Upgrading isn’t automatic. Follow this checklist to determine if it’s the right move for you:
- Evaluate current performance: Does your iPhone 8 Plus freeze, crash, or take more than 10 seconds to open common apps?
- Check iOS version: Are you running iOS 16 or earlier? If so, you’re missing critical security updates.
- Assess battery health: Go to Settings > Battery > Battery Health. If maximum capacity is below 80%, consider a replacement—or upgrade.
- Review your usage: Do you use navigation, video calls, mobile banking, or photo editing regularly? These demand modern processing power.
- Calculate long-term cost: A refurbished iPhone 13 starts around $400 in 2025. Compare that to potential repair costs, lost productivity, or data risks from outdated software.
Frequently Asked Questions
Will apps stop working on my iPhone 8 Plus in 2025?
Yes, gradually. Developers are optimizing apps for newer iOS versions and A12+ chips. By 2025, many updated apps—including banking, social media, and productivity tools—may not install or run properly on iOS 16 or older systems.
Can I keep using my iPhone 8 Plus as a backup device?
Absolutely. After upgrading, repurpose your 8 Plus as a dedicated music player, kid’s tablet, or car GPS. Just avoid using it for sensitive logins or financial apps due to lack of security updates.
Is the iPhone 13 waterproof like newer models?
Yes. The iPhone 13 has an IP68 rating (up to 6 meters for 30 minutes), making it highly resistant to water and dust—far superior to the 8 Plus’s splash resistance.
Conclusion: Future-Proofing Your Digital Life
Upgrading from the iPhone 8 Plus to the iPhone 13 in 2025 isn’t just about better photos or faster speeds. It’s about staying secure, connected, and capable in a world that increasingly demands modern hardware.
The iPhone 13 offers five more years of relevance. The iPhone 8 Plus offers nostalgia—and diminishing returns. If you rely on your phone for communication, creativity, or commerce, the upgrade pays for itself in time saved, stress reduced, and opportunities enabled.
