Apple iPhone 17 Pro: A3523 / A3526 (nano-SIM + eSIM) · 256 GB, 512 GB, 1 TB; Silver, Cosmic Orange, Deep Blue. eSIM-only country models carry a larger battery; the 6.9-inch iPhone 17 Pro Max is a separate model.

Apple iPhone 12: iPhone 12; 64, 128 and 256 GB. Apple’s UK spec page lists model A2403; bands depend on the model number. The iPhone 12 mini, 12 Pro and 12 Pro Max are separate models.

SpecificationApple iPhone 17 ProApple iPhone 12
Release year20252020
Display6.3-inch Super Retina XDR OLED; 2622 × 1206 pixels, 460 ppi; ProMotion adaptive refresh up to 120 Hz; Always-On

ProMotion raises the refresh rate to 120 Hz for scrolling and games and lowers it for static content to save power, which lets the Always-On lock screen stay lit at a very low rate. Measured as a standard rectangle the diagonal is 6.27 inches.

Apple
6.1-inch Super Retina XDR OLED; 2532 × 1170 at 460 ppi; HDR display, True Tone, Wide colour (P3), Haptic Touch

The display is 60 Hz; Apple does not list ProMotion for this model. Because of the rounded corners the rectangle measures 6.06 inches and the actual viewable area is slightly less. True Tone adjusts white balance to ambient light.

Apple
Brightness and contrast1,000 nits max typical, 1,600 nits peak HDR, 3,000 nits peak outdoor, 1 nit minimum; 2,000,000:1 typical contrast

3,000 nits is a short peak reached in sunlight under auto-brightness, not sustained full-screen brightness. The 1-nit floor helps reading in the dark without glare.

Apple
625 nits max brightness (typical); 1,200 nits max brightness (HDR); 2,000,000:1 contrast

1,200 nits applies only to HDR video and photos; the normal interface tops out at 625 nits. The 2,000-nit outdoor mode of newer iPhones is not on this model.

Apple
Front and back glassCeramic Shield 2 front with fingerprint-resistant oleophobic and anti-reflective coatings; Ceramic Shield back

Apple says Ceramic Shield 2 resists scratches 3x better than the previous generation, and the back resists cracks 4x better than the previous back glass. The anti-reflective coating is meant to keep the screen readable in bright light.

Chassis and cooling7000-series aluminium unibody; laser-welded vapor chamber filled with deionised water

The vapor chamber spreads A19 Pro heat into the chassis; Apple claims up to 40% better sustained performance than the previous generation. Aluminium conducts heat better than the titanium frame of earlier Pro models.

Apple

ChipA19 Pro; 6-core CPU (2 performance, 4 efficiency), 6-core GPU with Neural Accelerators, 16-core Neural Engine; hardware ray tracing

Neural Accelerators in the GPU cores speed up on-device AI work; hardware ray tracing computes realistic lighting and reflections in games.

Apple
A14 Bionic chip; 6-core CPU with 2 performance and 4 efficiency cores, 4-core GPU, 16-core Neural Engine

The Neural Engine speeds up photo processing such as Deep Fusion and Night mode and other on-device machine-learning tasks.

Apple
Storage256 GB, 512 GB or 1 TB

Usable space is lower than the label because the OS and apps take room. There is no memory card slot.

Apple
64 GB, 128 GB or 256 GB

There is no memory card slot; formatted capacity is lower.

Apple
Main camera48MP Fusion Main, 24 mm, ƒ/1.78, second-generation sensor-shift OIS; 12MP 2× (48 mm) optical-quality crop

The 2× view is not a separate lens; it uses the centre of the 48MP sensor for a 12MP image. Default photos are 24MP.

Apple
—
Ultra Wide camera48MP Fusion Ultra Wide, 13 mm, ƒ/2.2, 120° field of view; 48MP macro

Macro shots use the Ultra Wide camera; the phone can switch automatically when you get close to a subject.

Apple
—
Telephoto camera48MP Fusion Telephoto, 100 mm (4×), ƒ/2.8, tetraprism, 3D sensor-shift OIS; 12MP 8× (200 mm) optical-quality; 40× digital zoom

8× (200 mm) is a crop from the centre of the 4× telephoto sensor, which Apple calls optical-quality zoom. The telephoto sensor is 56% larger than the previous generation's.

Video4K Dolby Vision up to 120 fps; ProRes and ProRes RAW (4K 120 fps with external recording), Apple Log 2, ACES, Genlock; Cinematic mode 4K 30 fps; four studio-quality mics

4K 120 fps ProRes records only to external storage over USB-C. Apple Log 2 and ProRes RAW leave room for colour grading; Genlock keeps several cameras in sync.

Apple
HDR video with Dolby Vision up to 4K at 30 fps; 4K at 24/25/30/60 fps; 1080p slo-mo at 120/240 fps; cinematic stabilisation; HEVC and H.264

Dolby Vision recording is limited to 30 fps at 4K; 4K at 60 fps does not use Dolby Vision HDR. 8 MP stills can be taken while recording 4K.

Apple
Front camera18MP Center Stage, ƒ/1.9, autofocus; 4K Dolby Vision up to 60 fps; Dual Capture

The square sensor allows landscape group selfies while holding the phone upright; Dual Capture records front and rear cameras at once, up to 4K 30 fps.

Apple
—
BatteryUp to 31 hours video playback, 28 hours streamed; built-in lithium-ion

These figures are for the nano-SIM + eSIM model (A3523/A3526). Apple says eSIM-only models last longer because they fit a bigger battery.

Apple
—
Wired chargingUp to 50% in 20 minutes with a 40 W or higher USB-C adapter; adapter not in the box

Fast charging needs a high-wattage USB Power Delivery adapter; a 20 W adapter charges more slowly.

Apple
—
Wireless chargingUp to 25 W with MagSafe and Qi2; 50% in 30 minutes with a 30 W+ adapter and MagSafe Charger

25 W needs the new MagSafe Charger or a Qi2 25 W-capable charger; older Qi chargers run at lower power.

Apple
—
USB-CUSB 3 up to 10 Gb/s; 4K HDR video out over DisplayPort; charging

10 Gb/s needs a USB 3 cable; the cable in the box is a charging cable. Video can go to a monitor or TV over a suitable USB-C cable.

WirelessApple N1 chip: Wi-Fi 7 (802.11be, 2×2 MIMO), Bluetooth 6, Thread; second-generation Ultra Wideband; NFC with reader mode

Thread builds a low-power mesh with smart-home devices; Ultra Wideband finds AirTags and compatible devices with direction and distance. Wi-Fi 7 needs a compatible router.

Apple
5G (sub-6 GHz) with 4x4 MIMO; Gigabit LTE; Wi-Fi 6 (802.11ax) with 2x2 MIMO; Bluetooth 5.0; Ultra Wideband chip; NFC with reader mode

The UK page lists model A2403; bands depend on the model number and this page has no mmWave. Express Cards with Power Reserve keep some transit cards usable for a few hours after the battery runs out.

Apple
Cellular and SIM5G sub-6 GHz and Gigabit LTE (4×4 MIMO); nano-SIM and eSIM, dual eSIM support

This model has a physical SIM tray; models sold in some countries are eSIM-only. eSIM needs carrier support.

Apple

Location and safetyDual-frequency GPS, GLONASS, Galileo, QZSS, BeiDou, NavIC; Emergency SOS, Find My and Roadside Assistance via satellite; Crash Detection

Dual-frequency GPS reduces location drift among tall buildings. Satellite features vary by country; Apple offers them free for two years after activation.

Service programme—Free service programme for receiver (earpiece) no-sound issues; iPhone 12 and 12 Pro made between October 2020 and April 2021

Apple says a very small percentage of devices may have a failing component in the receiver module, so no sound is heard on calls. The programme covered units for 3 years after first retail sale and does not extend the warranty; other damage such as a cracked screen may need fixing first. The iPhone 12 mini and 12 Pro Max are not included.
