⚠️ Important: The iPhone 6 Plus was discontinued in September 2016 and no longer receives iOS updates beyond version 12.5.7, released in January 2023.
The specifications above represent the complete technical capabilities of all iPhone 6 Plus models. Model numbers include A1522 (North America), A1524 (Europe/Asia), and A1593 (China Mobile).
Each model shares identical core specifications but differs in cellular band support. The A1524 model offers the broadest LTE compatibility across international networks.
Display and Screen Technology
The iPhone 6 Plus introduced Apple’s first “Retina HD” display, marking a significant departure from previous iPhone screen sizes.
The 5.5-inch diagonal measurement represented a 68% increase in display area compared to the iPhone 5s. This IPS LCD panel delivers 1920 x 1080 resolution at 401 pixels per inch.
Display brightness reaches 500 cd/m² (typical) with a 1300:1 contrast ratio. The screen features dual-domain pixels for improved viewing angles up to 178 degrees.
Retina HD: Apple’s marketing term for displays with pixel density high enough that individual pixels are indiscernible at typical viewing distances, specifically 401 ppi for the iPhone 6 Plus.
The display includes a fingerprint-resistant oleophobic coating and supports Display Zoom and Standard view modes. In my experience, the Standard mode provided the best balance between content density and readability.
Color accuracy measures approximately 99% of the sRGB color space. The display lacks the wide color gamut (P3) support found in later iPhone models.
One unique aspect: the iPhone 6 Plus internally renders at 2208 x 1242 pixels, then downsamples to 1920 x 1080 for display. This approach improves image quality but adds minimal processing overhead.
Processor and Performance Details
The Apple A8 processor powers the iPhone 6 Plus with a dual-core design running at 1.4 GHz.
Built on a 20-nanometer process by TSMC, the A8 contains approximately 2 billion transistors. This represented a 13% size reduction compared to the A7 while delivering 25% faster CPU performance.
The processor utilizes Apple’s second-generation 64-bit architecture based on ARMv8-A instruction set. Each core features 64KB L1 instruction cache, 64KB L1 data cache, and shares 1MB of L2 cache.
| Component | Specification | Performance Impact |
|---|---|---|
| CPU Cores | 2x Typhoon @ 1.4 GHz | Single-core: 1630, Multi-core: 2920 (Geekbench 3) |
| GPU | PowerVR GX6450 (4 cores) | 50% faster than A7 GPU |
| RAM | 1 GB LPDDR3 | 25.6 GB/s memory bandwidth |
| Co-processor | M8 Motion | Dedicated sensor processing, barometer support |
The M8 motion coprocessor handles sensor data from the accelerometer, gyroscope, compass, and barometer. This offloads sensor processing from the main CPU, improving battery life during fitness tracking.
In real-world use, the A8 handled iOS 8 through iOS 11 smoothly. Performance degradation became noticeable with iOS 12, particularly when multitasking or using newer apps designed for more capable processors.
Camera System and Photography Features
The iPhone 6 Plus features an 8-megapixel iSight camera with several photography innovations for its time.
The rear camera uses a 1/3-inch sensor with 1.5µm pixels and an f/2.2 aperture. Most significantly, it introduced optical image stabilization (OIS) to the iPhone lineup, exclusive to the Plus model.
OIS compensates for hand movement by physically moving the lens element, enabling sharper photos in low light and smoother video recording. In my testing, OIS allowed shutter speeds 3-4 stops slower than the standard iPhone 6.
Optical Image Stabilization (OIS): A hardware feature that physically moves the camera lens to counteract hand shake, resulting in sharper images and smoother video compared to digital stabilization.
Video recording capabilities include 1080p at 30 or 60 fps, and 720p at 240 fps for slow motion. The camera supports time-lapse video and cinematic video stabilization.
The True Tone dual-LED flash adjusts color temperature based on ambient lighting. Focus Pixels technology provides phase-detection autofocus, significantly faster than the contrast-detection system in earlier iPhones.
The front-facing FaceTime HD camera captures 1.2-megapixel photos and 720p video. While modest by modern standards, it introduced burst mode for selfies and improved face detection.
Connectivity, Battery, and Other Specifications (2026)
The iPhone 6 Plus supports comprehensive wireless connectivity for its era.
Cellular capabilities include LTE Advanced with up to 150 Mbps download speeds across 20 LTE bands (model-dependent). The device supports VoLTE for higher quality voice calls over LTE networks.
Wi-Fi 802.11ac provides speeds up to 433 Mbps on 5GHz networks. Bluetooth 4.2 enables connection to wireless accessories with improved speed and privacy features.
- NFC: Limited to Apple Pay only (no general NFC access)
- GPS: Assisted GPS and GLONASS for location services
- Lightning Port: Proprietary connector for charging and data transfer
- Audio: 3.5mm headphone jack (last Plus model to include it)
The 2915 mAh lithium-polymer battery provides approximately 24 hours of talk time on 3G networks. Real-world battery life typically ranged from 8-10 hours of mixed use when new.
After 2-3 years, battery degradation becomes significant. My device required daily charging by year two, and twice-daily charging by year three before replacement.
✅ Pro Tip: Battery replacement costs $29-$79 and can restore near-original performance to older devices experiencing shutdowns or throttling.
Design, Dimensions, and Build Quality
The iPhone 6 Plus features an aluminum unibody design measuring 158.1 x 77.8 x 7.1 millimeters.
At 172 grams, it weighs 43 grams more than the iPhone 6. The 7.1mm thickness made it Apple’s thinnest phone at launch, contributing to structural concerns.
The design incorporates antenna breaks across the rear panel for improved cellular reception. These plastic lines became a signature visual element of this generation.
Touch ID fingerprint sensor sits within the home button, using a sapphire crystal surface and stainless steel detection ring. Second-generation Touch ID wasn’t introduced until the iPhone 6s.
⏰ Known Issue: The aluminum frame’s thin profile near the volume buttons creates a structural weak point, leading to the infamous “Bendgate” controversy affecting 5-10% of devices.
Build materials include aerospace-grade 6000 series aluminum and ion-strengthened glass. The camera lens features sapphire crystal protection, though some users reported scratching over time.
Available colors included Space Gray, Silver, and Gold. The Gold variant proved particularly popular in Asian markets, often commanding higher resale values.
Historical Context and Modern Comparison
The iPhone 6 Plus marked Apple’s entry into the phablet market, responding to competitive pressure from Samsung’s Galaxy Note series.
In 2014, the device competed directly with the Samsung Galaxy Note 4, LG G3, and Google Nexus 6. Its 5.5-inch display seemed enormous compared to the 4-inch iPhone 5s but small against today’s 6.7-inch iPhone 15 Pro Max.
The A8 processor delivered benchmark scores of approximately 1630 (single-core) and 2920 (multi-core) in Geekbench 3. For comparison, the iPhone 15 Pro’s A17 Pro scores about 2900 and 7400 in Geekbench 6, representing roughly 8x performance improvement.
| Specification | iPhone 6 Plus (2014) | iPhone 15 Plus (2026) | Improvement |
|---|---|---|---|
| Display Size | 5.5 inches | 6.7 inches | +22% |
| Processor | A8 (20nm) | A16 Bionic (4nm) | ~8x faster |
| RAM | 1 GB | 6 GB | 6x increase |
| Main Camera | 8 MP | 48 MP | 6x resolution |
| Starting Price | $749 (2014) | $899 (2026) | +20% |
Today, the iPhone 6 Plus serves primarily as a budget device, backup phone, or collector’s item. Unopened units command $200-$500 on collector markets, while used devices typically sell for $50-$150.
The device’s historical significance remains substantial. It established the Plus/Max product line that continues today and proved consumer demand for larger iPhone displays.
Known Issues and Specifications Impact (2026)
Two major hardware issues affect iPhone 6 Plus reliability and longevity.
Touch Disease affects an estimated 20-30% of iPhone 6 Plus units. The issue manifests as a flickering gray bar at the top of the display and unresponsive touch input.
This problem results from inadequate underfill around the Touch IC chips on the logic board. Repeated flexing causes solder joints to crack, requiring professional micro-soldering repair costing $149-$329.
Bendgate describes the device’s susceptibility to permanent bending under pressure. The 7.1mm aluminum frame lacks sufficient rigidity near the volume buttons, creating a failure point affecting 5-10% of devices.
