The iPhone 6, released in September 2014, marked a pivotal shift in Apple’s smartphone design philosophy. It was the first major departure from the compact form factor that defined earlier models, introducing a larger display and refined aesthetics. While newer iPhones have since taken center stage, the iPhone 6 remains relevant in secondhand markets and for users seeking an affordable entry into the iOS ecosystem. Before purchasing one today—whether as a backup phone, gift, or budget-friendly device—it's essential to understand its standout features and limitations. This guide dives deep into the ten most valuable aspects of the iPhone 6, helping you make an informed decision based on real-world performance and usability.
1. Sleek, Modern Design with Premium Build Quality
Apple redesigned the iPhone 6 with a focus on elegance and ergonomics. The aluminum unibody construction gives it a premium feel, while the chamfered edges and curved back improve grip and comfort. At 6.9mm thick, it was among the slimmest smartphones of its time. The rounded corners and smoother silhouette made it significantly more pocketable than its boxier predecessors like the iPhone 5s.
Available in Space Gray, Silver, and Gold finishes, the iPhone 6 offered a level of visual sophistication that appealed to both casual users and tech enthusiasts. Its minimalist design language set the standard for future iPhones and influenced the broader smartphone industry.
2. Larger Retina HD Display for Better Media Experience
The iPhone 6 introduced a 4.7-inch Retina HD display with a resolution of 1334x750 pixels at 326 ppi. This was a significant upgrade over the 4-inch screen of previous models, offering more screen real estate for browsing, reading, and watching videos. The increase in size improved multitasking efficiency and made on-screen keyboards easier to use.
While not as sharp as later Retina displays, the IPS LCD panel delivers accurate color reproduction, wide viewing angles, and excellent brightness under indoor lighting. For everyday tasks—from checking emails to streaming music—the display remains functional and visually pleasing even by today’s standards.
Display Comparison Across Key iPhone Models
| Model | Screen Size | Resolution | PPI |
|---|---|---|---|
| iPhone 5s | 4.0\" | 1136x640 | 326 |
| iPhone 6 | 4.7\" | 1334x750 | 326 |
| iPhone 7 | 4.7\" | 1334x750 | 326 |
| iPhone 12 Mini | 5.4\" | 2340x1080 | 476 |
3. A8 Chip with M8 Coprocessor: Surprisingly Capable Performance
Beneath the surface, the iPhone 6 runs on Apple’s custom A8 chip—a 64-bit processor clocked at 1.4GHz—paired with the M8 motion coprocessor. In its prime, this combination delivered smooth performance for iOS 8 through iOS 12. Even today, the A8 can handle basic apps like Safari, Messages, WhatsApp, and older versions of Instagram or Spotify without major lag.
The M8 coprocessor continuously gathers data from the accelerometer, gyroscope, barometer, and GPS, enabling advanced fitness tracking and contextual awareness in health apps. This feature is particularly useful for users interested in step counting or elevation tracking without needing a wearable device.

4. Improved iSight Camera with Smart Features
The 8MP iSight rear camera may seem modest by modern standards, but it was engineered for quality over quantity. With larger pixels (1.5µm), an f/2.2 aperture, and Focus Pixels technology, it captured sharp, well-exposed photos in daylight. The True Tone flash adjusted color temperature dynamically, reducing harsh skin tones in low light.
Video recording reached up to 1080p at 60fps, a notable improvement for action shots or smoother playback. Additional software enhancements included slo-mo video at 240fps, time-lapse mode, and auto HDR—all accessible directly from the native Camera app.
Real Example: Everyday Use Case
Sarah, a college student in 2015, relied solely on her iPhone 6 to document campus life. She uploaded event photos to social media, recorded short lectures, and used the panorama mode for scenic views during field trips. Despite lacking dual lenses or night mode, she found the camera reliable and consistent across varying conditions.
5. Touch ID for Secure and Convenient Access
The second-generation Touch ID sensor on the iPhone 6 offered faster fingerprint recognition than the original version in the iPhone 5s. It enabled secure unlocking, iTunes/FaceTime authentication, and Apple Pay transactions. This integration laid the foundation for biometric security in daily digital interactions.
Although slower than Face ID or modern capacitive sensors, Touch ID remains functional for basic security needs. Users who prioritize simplicity over facial recognition will appreciate its tactile reliability—even with gloves off.
6. Long-Lasting iOS Support and Security Updates
One of the iPhone 6’s strongest advantages was its extended software lifecycle. It launched with iOS 8 and received updates all the way up to iOS 12.5.7 (released in January 2023), making it one of the longest-supported iPhones in history. This longevity ensured access to critical security patches long after newer models were released.
However, it does not support iOS 13 or later, which means missing out on features like Dark Mode, App Library, and enhanced privacy controls. Apps requiring iOS 13+ will no longer install, limiting functionality over time.
Do’s and Don’ts When Using an Older iPhone
| Do | Don't |
|---|---|
| Use lightweight browsers like Opera Mini | Install resource-heavy games |
| Keep only essential apps | Run multiple background apps simultaneously |
| Enable automatic security updates when available | Connect to public Wi-Fi without a VPN |
7. Reliable LTE Connectivity and Battery Life
The iPhone 6 supports LTE Advanced with faster download speeds compared to earlier models. It also includes Bluetooth 4.0, Wi-Fi 802.11a/b/g/n (dual-band), and NFC—though NFC was initially limited to Apple Pay and not open for general use until later iOS versions.
Battery life averages around 10 hours of mixed usage, sufficient for a full day for light users. Charging via Lightning cable takes about 2 hours from 0 to 100%. Unfortunately, it lacks fast charging and wireless charging capabilities found in newer devices.
8. Compact Size Meets Functional Ergonomics
In an era where flagship phones exceed 6 inches, the iPhone 6 feels refreshingly compact. Its 4.7-inch screen fits comfortably in one hand, making navigation intuitive without excessive thumb stretching. This makes it ideal for users who dislike oversized devices or have smaller hands.
The placement of the power button on the side (rather than the top, as in older models) improves accessibility. Combined with the rounded shape, it slips easily into pockets and resists snagging on fabric.
9. Access to the Full iOS Ecosystem
Despite its age, the iPhone 6 grants access to iCloud, iMessage, FaceTime, Siri, and the App Store (with limitations). You can sync notes, photos, and reminders across Apple devices, use AirDrop with nearby Macs or iPads, and enjoy seamless integration within the ecosystem.
For families already invested in Apple products, pairing a used iPhone 6 as a child’s first phone or a secondary device offers cost-effective continuity without sacrificing core functionality.
10. Affordable Entry Point into iOS
Today, the iPhone 6 can be purchased secondhand for as little as $30–$60, depending on condition and storage capacity (16GB, 64GB, or 128GB). This makes it one of the cheapest ways to experience iOS firsthand—ideal for students, seniors, or those transitioning from Android.
While app compatibility is shrinking, many essential services still offer legacy support. Basic productivity tools, messaging platforms, and web browsers remain usable, especially if optimized settings are applied.
