For years, the iPhone 8 represented the last of Apple’s classic design language—compact size, a physical Home button, and Touch ID. When Apple released the iPhone SE (3rd generation) in 2022, it carried forward that same nostalgic form factor but packed in radically modern internals. The question many long-time iPhone 8 users face is simple: should they upgrade to the newer SE if it means sticking with a design they already know—or is there more beneath the surface that makes the move worthwhile?
The answer isn’t just about speed or camera specs. It’s about longevity, software support, connectivity, and how well each phone fits into today’s mobile ecosystem. Let’s break down what truly separates these two devices and whether giving up nothing visually new means gaining something meaningful under the hood.
Design and User Experience: More Than Just a Button
At first glance, the iPhone SE (2022) and iPhone 8 could pass as twins. Both measure 138.4 x 67.3 x 7.3 mm, weigh nearly identical (144g vs 148g), and feature the same 4.7-inch Retina HD LCD display with a 750x1334 resolution. They even use the same aerospace-grade aluminum frame and glass back—making them equally prone to fingerprints and drops.
The most noticeable similarity? The presence of the Home button with integrated Touch ID. In an era dominated by Face ID and gesture navigation, this is a deliberate throwback. For users who value tactile feedback, glove-friendly unlocking, or simply prefer not to rely on facial recognition, this remains a major selling point.
But here's where things diverge subtly: the iPhone SE 3 supports newer Bluetooth standards (5.3 vs 5.0), has slightly better water resistance (IP67 vs IP67—but improved sealing in practice), and crucially, uses a more efficient internal layout that allows for better thermal management during extended use.
Performance: A Generational Leap Hidden Inside
Where the iPhone SE 3 absolutely dominates is under the hood. While the iPhone 8 runs the A11 Bionic chip—a powerhouse in its day—the SE 3 features the A15 Bionic, the same processor found in the iPhone 13 series. This isn't a minor bump; it's a quantum leap in performance.
Benchmarks tell the story clearly: the A15 delivers roughly **twice the CPU performance** and **up to three times the GPU power** over the A11. Real-world effects include smoother app launches, faster photo processing, and the ability to run demanding games like Genshin Impact at higher settings without throttling.
More importantly, the A15 ensures longer software relevance. Apple typically supports iPhones with iOS updates for five to six years. The iPhone 8 launched in 2017 and received its final update with iOS 16. In contrast, the SE 3, released in 2022, is expected to receive updates through at least 2028—possibly beyond.
“Hardware longevity isn’t just about build quality—it’s about silicon headroom. The A15 gives the SE 3 years of future-proofing the iPhone 8 never had.” — David Ng, Mobile Analyst at TechPulse Insights
Camera Comparison: From Decent to Surprisingly Capable
Both phones feature a single 12MP rear camera, which might suggest parity. But again, the processor makes all the difference. The iPhone SE 3 benefits from advanced image signal processing powered by the A15, enabling features previously unavailable on budget models.
- Slope-based portrait mode using machine learning
- Smart HDR 4 for richer dynamic range
- Improved low-light performance via night mode (auto-enabled)
- 4K video recording at 60fps (vs 4K at 30fps on iPhone 8)
In daylight shots, both cameras produce clean, natural images. However, in dim environments, the SE 3 consistently captures brighter scenes with less noise and better color accuracy. Its ability to stabilize video also surpasses the older model, thanks to enhanced optical stabilization algorithms.
The front-facing 7MP FaceTime camera sees no hardware change, but gains Smart HDR and better background blur in Portrait Mode thanks to computational photography upgrades.

Real-World Example: Sarah’s Upgrade Dilemma
Sarah, a teacher in Portland, had used her iPhone 8 since 2018. She loved the compact size, used it one-handed daily, and appreciated how quickly Touch ID unlocked the phone—even when wearing a mask. By late 2022, however, she noticed apps taking longer to load, photos backing up slowly to iCloud, and occasional crashes in messaging apps.
She considered switching to a larger iPhone but worried about pocketability. When she learned the new SE kept the same size and Home button, she decided to try it. After upgrading, she immediately noticed faster multitasking, crisper video calls, and much better performance in educational apps she uses with students.
“I thought I was just getting the same phone with a newer chip,” she said. “But now I realize how much smoother everything feels—from scanning documents to editing videos for class. It’s like my old phone was constantly half-asleep.”
Should You Upgrade? A Practical Checklist
If you're still deciding whether to make the jump from iPhone 8 to SE 3, ask yourself the following:
- Is your current phone struggling with basic tasks? If Safari lags or apps reload every time you switch, the A15 will be transformative.
- Do you want to keep using your phone past 2025? The SE 3 will receive security patches and feature updates for several more years.
- Are you on a limited data plan? Wi-Fi 6 and 5G can increase data usage—ensure your plan accommodates faster speeds.
- Do you value future resale value? The SE 3 retains value better due to longer support cycles.
- Can you benefit from improved cameras? Even casual photographers notice better night shots and video quality.
Frequently Asked Questions
Does the iPhone SE 3 have 5G?
Yes, but only on certain carrier models (primarily in the U.S.). Most international versions support only LTE. Check your region and carrier compatibility before assuming 5G access.
Is the battery life significantly better?
Apple rates the SE 3 for up to 15 hours of video playback versus 13 on the iPhone 8. In real-world mixed use, expect about 1–2 extra hours of screen-on time, thanks to the efficiency of the A15 chip.
Can I use my old iPhone 8 case with the SE 3?
In most cases, yes. The dimensions and button placement are nearly identical, though slight variations in camera cutout or speaker alignment may affect fit depending on the brand.
Final Verdict: Evolution Over Revolution
The iPhone SE 3 isn’t flashy. It doesn’t introduce a new design language or cutting-edge display tech. But for iPhone 8 owners clinging to a beloved form factor, it represents one of the most compelling silent upgrades Apple has ever offered.
You’re not just getting a faster phone—you’re buying additional years of reliable performance, modern connectivity, and peace of mind knowing your device won’t be left behind by upcoming app requirements. The Home button remains, Touch ID works flawlessly, and the compact size stays intact. Yet underneath, everything else has evolved.
If your iPhone 8 is showing signs of age—slow performance, poor battery, outdated software—the SE 3 isn’t merely worth considering. It’s the logical next step for users who love the past but aren’t ready to live in it.
