Display6.1-inch Super Retina XDR OLED; 2556 × 1179 at 460 ppi; Dynamic Island

Dynamic Island turns the front camera cut-out into an area for alerts and live activities. Apple does not list ProMotion for this model, so the screen is not 120 Hz.

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 contrast1000 nits typical; 1600 nits HDR peak; 2000 nits outdoor peak; 2,000,000:1 contrast

The outdoor peak is used briefly in strong sunlight; the HDR peak applies to HDR video and photos.

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.

BatteryUp to 20 hours of video playback, 16 hours streamed, 80 hours of audio Apple—
USB-C and chargingUSB-C, USB 2 (up to 480 Mb/s), DisplayPort; about 50% in 30 minutes with a 20 W or higher adapter; MagSafe and Qi2 up to 15 W, Qi up to 7.5 W

Although the connector is USB-C, data runs at USB 2 speed, so moving large video files by cable takes longer than over the USB 3 port on the Pro models.

Apple

SIMDual eSIM (two active eSIMs at once)

Apple’s page also shows a SIM tray on models sold outside the US, so physical SIM support depends on the country of purchase.

Apple
Dual SIM (nano-SIM and eSIM)

eSIM use depends on carrier support.

Operating conditions—Ambient temperature 0–35 °C; relative humidity 5–95% non-condensing; tested up to 3,000 m altitude Apple
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.
