Apple iPhone Duo vs Apple iPhone 17

Apple does not publish battery capacity in mAh. Up to 50% in around 20 minutes with a separately sold 60 W-capable or higher USB-C adapter; MagSafe and Qi2 up to 25 W. Apple claims, not independent tests.

Playback and charge setups are distinct manufacturer claims, not mixed-use battery life or measured sustained input.

TrueDepth-based facial recognition; wording differences do not create a separate unlock method.

The UK physical nano-SIM capability explicitly establishes that this configuration is not eSIM-only.

The physical rigid single-display model description identifies the form.

Front-camera optics and autofocus are read separately from the rear system.

Directly published ppi, not calculated from rounded screen size.

Inner display when open; outer display is 5.4 inches.

Advertised nominal diagonal, not actual viewable area.

Individually labelled dimensions were reordered explicitly to height × width × depth.

Labelled height in millimetres.

Labelled depth; camera-bump dimensions are not invented.

Device mass, not shipping mass; configuration and manufacture can vary.

Labelled width; larger is not inherently preferable.

Dual eSIM (two active eSIMs); no physical SIM slot; 5G (sub-6 GHz). Carrier eSIM support needs confirming with your network.

UK technical and regional model sections agree. A model identity is not a retailer-availability or carrier-support guarantee.

The model index explicitly identifies the US model and its lack of a SIM tray. UK battery and mass claims are not relabelled US.

No source recorded for this side.

One main-camera aperture is listed; ultra-wide f/2.2 is a separate lens.

No source recorded for this side.

Positive system flag is scoped to Fusion Main, not every rear lens.

Autofocus with Focus Pixels is explicitly listed.

No source recorded for this side.

Ultra-stabilised video and auto image stabilisation do not establish an optical mechanism.

No source recorded for this side.

Mode-specific 4K maximum, not ordinary rear recording.

Apple UK local-video claim; inner display. The 44-hour outer-display claim is a different mode. Different mode from the 31-hour inner-display claim. Published per display. Neither figure is a like-for-like match for a single-screen phone's claim, so it is not ranked against one.

Local-video up-to claim; not streamed or mixed-use endurance.

No source recorded for this side.

Lithium-ion construction is listed without mAh. Playback duration does not establish capacity.

The checked rear recording list does not establish ProRes; omission is not an absolute negative for every external/app workflow.

Mode-specific source claim, without assuming all playback workflows.

Inner display. Published per display. Neither figure is a like-for-like match for a single-screen phone's claim, so it is not ranked against one.

Separate streamed-video up-to claim.

No source recorded for this side.

Explicit typical maximum with a distinct measurement basis.

Apple typical-use claim based on equal use of the inner and outer displays; distinct from video playback and not a cross-brand endurance test.

No source recorded for this side.

N1 is explicitly a networking chip, not an identified cellular modem.

UWB is Apple's second-generation Ultra Wideband chip. Wi-Fi 7 and Ultra Wideband availability depend on region and compatible equipment. This sourced capability inventory is not measured throughput or evidence that a shorter peer inventory lacks a feature.
