For millions of iPhone users still relying on the iPhone 7, the question isn’t just about new features—it’s about practical value. The iPhone 8 arrived as a subtle evolution, not a revolution, but behind its familiar design lies meaningful upgrades that could impact your daily experience. If you're debating whether to upgrade from the iPhone 7 to the iPhone 8, the answer depends on how you use your phone, what you prioritize, and how long you plan to keep it.
The iPhone 7 was a milestone device—water resistance, a refined camera, and the removal of the headphone jack sparked both praise and controversy. The iPhone 8, released just one year later, kept much of that formula intact while introducing critical internal improvements. But is that enough to justify the switch?
Design and Build: Subtle Changes, Real Impact
At first glance, the iPhone 8 looks nearly identical to the iPhone 7. Both feature aluminum frames, similar button placements, and comparable dimensions. However, Apple made a significant structural change: the iPhone 8 swaps the aluminum back for glass. This allows for wireless charging—a feature absent on the iPhone 7.
The glass back does come with trade-offs. It’s more prone to cracking than aluminum and adds slight weight. But the ability to charge wirelessly using any Qi-compatible charger opens up new convenience, especially if you use charging pads at home or in the car.
Performance: A Noticeable Leap Under the Hood
The most impactful difference between the two models lies beneath the surface. The iPhone 8 is powered by the A11 Bionic chip, a 64-bit hexa-core processor with a neural engine designed for machine learning tasks. In contrast, the iPhone 7 uses the A10 Fusion chip.
Benchmarks show the A11 delivers up to 25% faster CPU performance and 30% better GPU performance. While this may not drastically change everyday tasks like texting or browsing, it translates into smoother multitasking, faster app launches, and better longevity when running future iOS updates.
Real-world usage confirms this edge. Users upgrading from the iPhone 7 to the iPhone 8 often report that animations feel snappier, games run more smoothly, and augmented reality (AR) apps perform significantly better—thanks in part to improved graphics processing and motion tracking.
“Even minor hardware improvements can extend a device’s usable life by years, especially as apps grow more demanding.” — David Lin, Mobile Performance Analyst at TechInsight Group
Camera Comparison: Refinements Over Revolution
Both phones feature a 12MP rear camera, but the iPhone 8 brings several enhancements:
- Larger and faster sensor with better low-light performance
- Improved color accuracy and dynamic range
- Optical image stabilization (OIS) on both standard and Portrait mode shots (iPhone 7 only has OIS on Plus model)
- Smarter HDR and noise reduction algorithms
In daylight, the differences are minimal. But in dim lighting or high-contrast scenes, the iPhone 8 consistently captures cleaner, brighter photos with less grain. Portrait Mode also benefits from better edge detection and depth mapping, making subject separation more natural.
The front-facing camera remains unchanged at 7MP, so selfies and video calls won’t see any improvement.
Display and Audio: Incremental Gains
The displays on both devices are 4.7 inches with IPS LCD technology and 1334x750 resolution. However, Apple claims the iPhone 8 has a “True Tone” display, which adjusts white balance based on ambient light to reduce eye strain. This results in warmer tones indoors and cooler tones in sunlight, mimicking paper-like readability.
While subjective, many users find True Tone makes prolonged reading or media consumption more comfortable. It’s a small but thoughtful upgrade, particularly for those sensitive to screen brightness.
Audio quality remains strong on both models. Stereo speakers are louder on the iPhone 8, offering roughly 25% higher peak volume. For music lovers or podcast listeners, this extra clarity and bass response can enhance the listening experience—especially without headphones.
Software Support and Longevity
As of 2024, both the iPhone 7 and iPhone 8 are no longer eligible for the latest iOS updates. iOS 17 was the final version supported by these devices. However, security patches may continue for a short time, and both phones remain functional for basic tasks.
That said, the iPhone 8’s superior hardware gives it a slight edge in future-proofing. Apps optimized for newer processors may run slower or become incompatible sooner on the A10 chip. If you plan to keep your phone beyond 2025, the iPhone 8 will likely age more gracefully.

Real-World Example: Sarah’s Upgrade Decision
Sarah had used her iPhone 7 since 2017. By 2023, she noticed her phone struggled with Instagram reels, took longer to open maps, and occasionally froze during FaceTime calls. She considered switching to Android but decided to explore iPhone options first.
After testing both phones in-store, she upgraded to a refurbished iPhone 8. The difference wasn’t dramatic, but the responsiveness felt immediate. Wireless charging simplified her morning routine, and her photos in low light improved noticeably. Most importantly, apps loaded faster, and multitasking became seamless again.
She extended her phone’s useful life by two additional years—well beyond what she expected from her aging iPhone 7.
Checklist: Should You Upgrade?
Use this checklist to determine if moving from iPhone 7 to iPhone 8 makes sense for you:
- ✅ Are you experiencing frequent app crashes or slowdowns?
- ✅ Do you want wireless charging capability?
- ✅ Do you take photos in low-light conditions regularly?
- ✅ Is your current battery health below 80%?
- ✅ Do you plan to keep your phone for another 2+ years?
- ✅ Are you still satisfied with the 4.7-inch screen size?
If you answered yes to three or more, the iPhone 8 is a worthwhile upgrade.
Frequently Asked Questions
Can the iPhone 8 last in 2024?
Yes, but with limitations. It runs iOS 17 and supports most essential apps, though performance may lag with heavy multitasking or newer games. For light to moderate use—calls, messaging, email, social media—it remains viable.
Is the camera upgrade worth it?
If you frequently shoot in dim lighting or value photo detail and consistency, yes. The improvements are subtle but tangible, especially in dynamic range and noise reduction. For casual snapshots, the difference may not be decisive.
Should I skip to a newer model instead?
If budget allows, consider iPhone XR or newer. These offer larger screens, Face ID, better batteries, and ongoing iOS support. However, if you prefer compact phones and want a cost-effective refresh, the iPhone 8 still holds value.
Final Verdict: Is It Worth Upgrading?
Upgrading from iPhone 7 to iPhone 8 isn’t about flashy changes—it’s about refinement and longevity. You won’t get a bezel-less display or Face ID, but you gain a faster processor, better camera performance, wireless charging, and slightly improved audio and screen comfort.
If your iPhone 7 is still running well and meets your needs, holding off is reasonable. But if you’re noticing performance issues, battery degradation, or frustration with slow app loading, the iPhone 8 offers a meaningful step forward without breaking the bank.
Ultimately, you’re not missing out by staying on the iPhone 7—but you’re also not falling behind by upgrading to the iPhone 8. It’s a smart, balanced choice for users who value reliability, compact design, and a touch of modern convenience.
