The iPhone 14 and iPhone 14 Plus feature a 6.1-inch (15 cm) and 6.7-inch (17 cm) display, improvements to the rear-facing camera, and satellite connectivity for contacting emergency services when a user in trouble is beyond the range of Wi-Fi or cellular networks.

Instead, a larger 6.7-inch display size option was added to the lower-priced iPhone 14 lineup.

[33] The cameras use Apple's latest computational photography engine, called Smart HDR 4.

Users can also choose from a range of photographic styles during capture, including rich contrast, vibrant, warm, and cool.

Apple clarifies this is different from a filter because it works intelligently with the image processing algorithm during capture to apply local adjustments to an image, and the effects will be baked into the photos, unlike filters which can be removed after applying.

[7] The camera app contains Cinematic Mode, which allows users to rack focus between subjects and create (simulate) shallow depth of field using software algorithms.

The area read out from the image sensor is moved between frames to counteract hand movements.

The next-generation Qi2 wireless charging standard was added to the iPhone 14 and 14 Plus with the update to iOS 17.2.

[11] As of November 2022, Globalstar operates a constellation of 25 satellites in low Earth orbit, with plans to enhance this in the future via its partnership with Apple.

[11][43] The service became available to US and Canada on November 15, 2022, and to the UK, Germany, Ireland, and France on December 13, 2022.

[48][49] Emergency dispatchers have received many false alarm calls from iPhone 14 and Apple Watch users who have been skiing safely.

In Colorado, a wave of false 9-1-1 calls led Aspen Mountain to advise device owners to upgrade their operating systems or disable the feature.

[51] While the iPhone 14 was originally lauded for its innovative new hardware design and recommended by iFixit, concerns over software limitations on parts not authorized by Apple caused iFixit to decrease their evaluation to a 4/10 or "not recommended" in September 2023.
