About the Apple iPhone 6S
The iPhone 6S is a decade-old handset now sitting firmly at the entry point of the used and refurbished market, and it needs to be judged on those terms rather than as a modern smartphone. Its aluminium unibody design still feels solid, and the 4.7-inch display is a comfortable one-handed size that some buyers now specifically seek out as newer phones have grown larger. The 12MP rear camera was genuinely impressive for its era and can still take reasonable photos in good light, though it falls well behind anything from the last few years in low light and video. The bigger issue is software: the 6S is capped at iOS 15, meaning it cannot run current apps that require newer iOS versions, and it no longer receives feature updates, only occasional security patches. Battery life on original cells is typically poor after a decade of charge cycles, so a refurbished unit with a replaced battery is strongly preferable to a used original. This phone only makes sense as a very cheap backup handset, a simple device for a child or older relative, or for someone who values a compact size above all else and accepts its serious software limitations.

Apple iPhone 6S Specifications
Spec Scores
£700-£999 Phones · 85 phones
- Apple A9 (14/16 nm - maker dependant)
- Dual-core 1.84 GHz Twister
Based on calibrated CPU benchmark rankings (60%) and GFXBench GPU scores (40%). Apple chipsets included via editorial calibration since AnTuTu under-represents Apple's architecture.
- 4.7 inches
- 750 x 1334 pixels
- IPS, 500 nits peak
Based on panel type (LTPO is the modern flagship gold standard), resolution, refresh rate, peak brightness, screen size, and HDR10+ / Dolby Vision support. Marketing peak-brightness claims are capped at 3500 nits to prevent inflation.
- Single camera setup
- 12 MP main camera
- 4K video recording
Based on main-sensor size (1-inch / 1/1.3" beats 1/2.0"), telephoto reach (periscope > 5x > 3x optical), image processing tier (Apple Pro, Pixel Pro, Galaxy Ultra, Honor Magic Pro, Xiaomi Ultra), pro video features (ProRes, Apple Log, Dolby Vision), camera-partnership branding (Leica, Hasselblad, Zeiss) and OIS. Older flagships are de-rated since image processing pipelines have advanced significantly each generation. Megapixel count is deliberately downweighted — it correlates poorly with real-world camera quality. Where DXOMARK has lab-tested the phone, its measured score replaces this estimate.
- 5 MP front camera
Based on the image-processing tier (Apple Pro, Pixel Pro, Galaxy Ultra and Honor Magic lead on computational processing), sensor resolution in tiers rather than raw megapixels, autofocus, aperture and max selfie-video resolution. Calibrated against DXOMARK's selfie protocol.
- 1,715 mAh
Based on battery capacity (mAh) adjusted for platform efficiency calibrated against NotebookCheck, Tom's Guide, GSMArena and CNET reviewer tests. Apple A-series gets +45% (iOS process freezing + LTPO 1Hz + tuned panels make iPhone Pro Max outlast many 6500+ mAh Android phones in measured tests). Top Snapdragon / Dimensity flagships get +15%, budget chipsets are penalised −15% to −25% to reflect less efficient displays and looser background limits. Charging speed is excluded — see the separate Fast charging tag for that.
