The dimensions are 6.33 x 3.07 x 0.29 inches (160.8 x 78.1 x 7.4 mm) and the weight of 8.03 ounces (228g), which is very large and heavy and the priority is the screen and the battery.

iPhone 12 Pro Max Display

First and foremost, the iPhone 12 Pro Max comes with a 6.7-inch Super Retina XDR OLED display and a stunning resolution of 2778 x 1284 pixels (458 PPI) which produces the most colourful decorations for content with HDR10 and Dolby Vision. The front camera and Face ID are embedded still on the notch, however, the display with its 60Hz refresh rate may be considered an obsolete feature with the arrival of the ProMotion technology. The screen peaks at 800 nits typical brightness and 1200 nits HDR brightness, which does a good job of outdoor visibility, but the phone is not supported by the latest models of Always-On Display.

It is installed with iOS 14, which can be updated to iOS 18; however, such featured as ProMotion, Dynamic Island, and the Always-On Display are missing from the phone at the moment.

• 20W wired charging (50% in 30 min)
• 15W MagSafe, 7.5W Qi wireless charging
