iPhone 15 vs iPhone 14

The iPhone 15 series introduced several advancements over the iPhone 14 series. Here’s a detailed comparison between the two:

Design and Build

  • Dimensions and Weight: Both the iPhone 14 and 15 maintain similar dimensions. The iPhone 15 is marginally longer than the 14 but retains the same width and thickness. The iPhone 15 is slightly lighter than its predecessor​​.
  • Construction: The iPhone 15 continues the design aesthetic of the iPhone 14, including aerospace-grade aluminum and glass front and back sides, with the front featuring Apple’s Ceramic Shield for durability​​.


  • Screen Technology: Both series use the Super Retina XDR OLED display. The iPhone 15 and 15 Plus have slightly higher resolutions than their iPhone 14 counterparts, providing sharper images​​.
  • Brightness and HDR: The iPhone 15 models offer increased brightness, with 1,000 nits for typical usage, 1,600 nits at peak for HDR, and 2,000 nits at peak for outdoor usage, compared to the iPhone 14’s 1,200 nits peak for HDR and 800 nits for typical usage​​.
  • Notch and Dynamic Island: The iPhone 14 has a notch at the top, whereas the iPhone 15 adopts the Dynamic Island UI function, a more integrated approach to the display cutout​​.


  • Rear Cameras: The iPhone 15 introduces a significant upgrade with a 48-megapixel main camera compared to the 12-megapixel cameras on the iPhone 14. The iPhone 15 also includes Quad Pixel technology, providing virtual telephoto capabilities​​.
  • Front Camera: Both series feature a 12-megapixel TrueDepth front camera with similar capabilities. However, the iPhone 15 claims to offer “next-generation portraits” with improved focus and depth control​​.

Processing Performance

  • Processor: The iPhone 15 uses the A16 Bionic chip, which was previously used in the iPhone 14 Pro models. This offers enhanced performance with two performance cores, four efficiency cores, a 5-core GPU with 50% more memory bandwidth, and a 16-core Neural Engine capable of 17 trillion operations per second​​.


  • Cellular and Wi-Fi: Both series support 5G, Gigabit LTE, Wi-Fi 6, and Bluetooth 5.3. However, the iPhone 15 introduces a second-gen Ultra Wideband chip, offering additional features like precision tracking of other iPhone 15 handsets​​.
  • Emergency Features: Both models include Emergency SOS via Satellite and Roadside Assistance via Satellite, with the iPhone 15 introducing the latter feature​​.

Power and Battery

  • Battery Life: Both the iPhone 14 and 15 offer similar battery life, with up to 20 hours of local video playback and up to 80 hours of audio playback for the base models, and better performance for the Plus models​​.
  • Charging: The iPhone 15 series switches from Lightning to USB-C for charging, although the charging speed and wireless charging capabilities remain similar to the iPhone 14​​.

Other Features

  • eSIM and SIM Card Support: Both series in the United States are eSIM-only, while other countries still offer physical SIM card support​​.
  • Water and Dust Resistance: Both maintain an IP68 rating for water and dust resistance​​.
  • Color Options and Pricing: The iPhone 15 is available in Black, Blue, Green, Yellow, and Pink, while the iPhone 14 was initially available in Midnight, Starlight, Blue, Purple, and (Product)Red, with a Yellow option added later. The pricing structure remains similar across both series​​.

In summary, the iPhone 15 series builds upon the foundation set by the iPhone 14, offering enhanced display technology, a significant camera upgrade, improved processor performance, and new connectivity features, while maintaining a similar design, battery life, and pricing structure.
