For many users still clinging to an iPhone 5, the decision to upgrade isn’t always about screen size or processor speed—it’s about the camera. After all, smartphones are now our primary cameras, used daily for everything from social media to documenting life’s fleeting moments. But does moving from an iPhone 5 to an iPhone 6, or even further to the 6s, deliver a meaningful improvement in photo quality? The answer depends on how you use your phone and what you expect from its camera.
The Evolution of Apple’s Camera Technology (2012–2015)
Between 2012 and 2015, Apple made incremental but significant improvements to its smartphone cameras. The iPhone 5, released in 2012, was praised at the time for its 8-megapixel sensor and backside illumination technology, which improved low-light performance. Two years later, the iPhone 6 brought design refinements and better image signal processing. Then came the iPhone 6s in 2015—a true leap forward with a completely redesigned camera system.
Each model reflects Apple’s growing focus on computational photography, even before the term became mainstream. While megapixels alone don’t tell the full story, they’re part of a broader shift in sensor quality, autofocus systems, software tuning, and video capabilities.

|---|---|---|---|
| Rear Camera Resolution | 8 MP | 8 MP | 12 MP |
| Aperture | f/2.4 | f/2.2 | f/2.2 |
| Autofocus | Basic contrast-detect | Improved contrast-detect | Laser-assisted Focus Pixels |
| Video Recording | 1080p @ 30fps | 1080p @ 30/60fps | 4K @ 30fps, 1080p @ 60/120fps |
| Front Camera | 1.2 MP, 720p video | 1.2 MP, 720p video | 5 MP, 1080p video |
| Flash | LED | True Tone LED | True Tone LED |
| Burst Mode Speed | Slow (~3 fps) | Moderate (~5 fps) | Fast (~10 fps) |
Real-World Photo Quality: What Changed?
On paper, the jump from 8MP to 12MP on the iPhone 6s seems modest, but in practice, it makes a noticeable difference. Higher resolution allows for more detail, better cropping flexibility, and sharper prints. More importantly, Apple paired the new sensor with advanced noise reduction algorithms and faster image processing via the A9 chip.
In daylight, all three phones can produce acceptable photos, but the iPhone 6s consistently delivers richer colors, better dynamic range, and finer textures. Shadows retain more detail, and highlights are less likely to blow out. The iPhone 5, by comparison, often struggles with overexposure and lacks fine detail in complex scenes like foliage or fabric patterns.
Low-light performance sees one of the most dramatic improvements. The iPhone 5’s f/2.4 aperture limits light intake, resulting in grainy, blurry night shots unless perfectly still. The iPhone 6’s wider f/2.2 lens helps, but it’s the 6s that introduces smarter software-based noise suppression and longer exposure bursts in Night mode-like conditions—though not officially labeled as such until later models.
Video Capabilities: From HD to 4K
If you record videos regularly, the iPhone 6s is in a different league. It supports 4K recording, which offers four times the resolution of standard 1080p. This matters if you plan to edit footage, zoom in during post-production, or view videos on large screens.
But beyond resolution, the 6s also enables smoother slow-motion at 1080p@120fps (vs. 720p@120fps on earlier models), making action sequences look more cinematic. The front-facing camera upgrade is equally important: turning selfies and FaceTime calls into much crisper experiences.
“Even two generations apart, the difference in video stability and clarity between iPhone 5 and 6s is striking—especially for parents filming kids’ events or travelers capturing quick clips.” — David Lin, Mobile Videographer & Tech Reviewer
A Mini Case Study: Sarah’s Upgrade Experience
Sarah had been using her iPhone 5 since 2013. She loved its compact size and reliability but grew frustrated when her photos didn’t match what she saw—blurry group shots, dim restaurant pictures, and pixelated social media uploads. After borrowing a friend’s iPhone 6s, she tested it during a weekend trip.
The results were immediate. Her sunset photos retained vibrant gradients instead of flattening into orange blobs. In a crowded market, she could zoom slightly into a stall sign without losing legibility. Most surprisingly, her selfie in a candlelit café came out bright and clear thanks to the improved True Tone flash and front camera processing.
She upgraded and hasn’t looked back. “It wasn’t just about better photos,” she said. “It changed how often I took them. I felt confident sharing them directly—no need to filter or fix them later.”
Is Upgrading Worth It? A Step-by-Step Decision Guide
Deciding whether to upgrade should be based on actual needs, not just specs. Follow this timeline to assess your situation:
- Evaluate your current pain points: Are your photos too dark, blurry, or lacking detail? Do videos appear choppy or low-res?
- Test sample photos: Compare side-by-side images taken with iPhone 5, 6, and 6s (available online or through friends).
- Assess your usage: Do you shoot often in low light? Record family videos? Share high-quality content online?
- Consider alternatives: Refurbished iPhone 6s units are still available at low cost. Used prices range from $30–$80, making it a budget-friendly upgrade.
- Weigh long-term value: iOS support ended for iPhone 5 in 2017, meaning no security updates or app compatibility. Even if the camera were perfect, functionality degrades over time.
Frequently Asked Questions
Can the iPhone 6s still run modern apps smoothly?
While the iPhone 6s launched with iOS 9 and supports up to iOS 15 (the last supported version), many newer apps function adequately. However, some resource-heavy apps (like advanced photo editors or AR games) may lag or lack features. For basic photography, messaging, and browsing, it remains usable in 2024.
Is there a big difference between iPhone 6 and 6s cameras?
Yes. Despite similar design and rear lens appearance, the 6s has a 50% higher resolution sensor, faster autofocus, better HDR processing, and dramatically improved front camera. Video jumps from 1080p to 4K. These changes make the 6s a worthwhile upgrade over the 6, especially for content creators.
Should I wait for a newer model instead?
If budget allows, yes. iPhone SE (2nd gen and later), iPhone 7 and above offer far superior cameras, longer software support, and better performance. But if you're choosing only among 5, 6, and 6s, the 6s is clearly the best value for camera quality.
Action Checklist Before Upgrading
- Back up your iPhone 5 data via iCloud or iTunes
- Check carrier compatibility (iPhone 6s supports more LTE bands than 5)
- Inspect battery health—older 6s units may need replacement
- Clear storage space if transferring large photo libraries
- Enable iCloud Photos to sync across devices seamlessly
Final Verdict: Yes, It’s Worth It—for the Camera and Beyond
Upgrading from an iPhone 5 to either the 6 or 6s brings tangible benefits, but only the 6s delivers a truly modern camera experience. The combination of 12MP resolution, faster processing, enhanced low-light performance, and 4K video transforms how you capture and share moments.
The iPhone 6 improves ergonomics and minor photo details, but doesn’t revolutionize imaging. The 6s, however, marks the beginning of Apple’s push toward intelligent photography—one where hardware and software work together to produce reliable, high-quality results in nearly any condition.
If your priority is camera performance, and you’re limited to these three models, the iPhone 6s is the only logical choice. It extends usability, future-proofs your device against app obsolescence, and most importantly, lets you take photos you’re proud to keep.
