phones also use an improved glass-ceramic covering called Ceramic Shield which is co-developed with Corning Inc. Apple describes it as having "4 times better drop performance" and being "tougher than any smartphone glass". Batteries The iPhone 12 has a 10.78 Wh (2,815 mAh) battery, a slight decrease from the 11.91 Wh (3,110 mAh) battery found in the iPhone 11 and identical to the battery found in the iPhone 12 Pro. The iPhone 12 Mini has a 8.57 Wh (2,227 mAh) battery. Like previous iPhones, the battery is not user-replaceable. Chipsets Both the iPhone 12 and 12 Mini have the Apple A14 Bionic, the first ARM-based smartphone system-on-a-chip (SoC) manufactured on the 5 nm process node. However, unlike previous years, they are not the first Apple devices to receive the newest A-series processor, with the fourth-generation iPad Air being the first. Both phones use Qualcomm's X55 5G modem. Cameras Both phones have two rear 12-megapixel cameras: wide and ultra-wide. The wide camera is a 26 mm full-frame equivalent with an f/1.6 aperture which captures 27% more light than the f/1.8 aperture in the iPhone 11 and a seven-element lens. The ultra-wide camera is a 13 mm full-frame equivalent with an f/2.4 aperture and a five-element lens. All cameras now support Night Mode for both photo and time-lapse video at full resolution. Smart HDR has been improved thanks to Smart HDR 3. This iPhone model is the first capable of shooting 10-bit high dynamic range Dolby Vision 4K video at up to 30 fps which allows for greater brightness and deeper shadows. The front-facing, TrueDepth camera features a 12-megapixel camera with an f/2.2 aperture. This model also added Night Mode to the front-facing camera. Sensors The iPhone 12 and 12 Mini include mostly the same sensors found on prior iPhone models going back to the iPhone X. These include an accelerometer, gyroscope, barometer, proximity sensor, ambient light sensor, and a digital compass. The devices also includes the Face ID sensor for biometric authentication. Software Both phones originally shipped with iOS 14. The devices come with the stock iOS apps, such as Safari, Weather, and Messages, and they include Siri, the personal assistant in iOS. They received iOS 15 on September 20, 2021, and they also support iOS 16 which was released on September 12, 2022. Reception The iPhone 12 received largely positive reviews. The Verge called it a "beautiful, powerful, and incredibly
