iPhone 15 vs iPhone 8: A Leap into the Future or Stick with the Classics?


In today’s fast-paced world, having a reliable smartphone is no longer a luxury—it’s a necessity. But with the plethora of options available, choosing the right one can be a daunting task. This blog post aims to make that task easier by comparing two different generations of iPhones: the iPhone 8 and the iPhone 15. And thanks to Plug’s amazing deals on certified pre-owned devices, you might find that a high-quality phone doesn't have to break the bank.

Design and Build

iPhone 15

  • Aerospace-Grade Aluminum Frame
  • Ceramic Shield Front Cover
  • IP68 Water and Dust Resistance

iPhone 8

  • Aluminum Frame
  • Glass Front and Back
  • IP67 Water and Dust Resistance

While both phones are constructed with high-quality materials, the iPhone 15 takes durability to another level with an aerospace-grade aluminum frame and ceramic shield front cover. Additionally, it features an improved IP68 water and dust resistance rating, compared to the iPhone 8’s IP67 rating.


iPhone 15

  • 6.1-inch ProMotion Super Retina XDR Display
  • HDR10, Dolby Vision, ProMotion Technology (120Hz)

iPhone 8

  • 4.7-inch Retina HD Display
  • No HDR or Dolby Vision Support

The iPhone 15 sports a much larger 6.1-inch ProMotion Super Retina XDR display that is a world apart from the iPhone 8's 4.7-inch Retina HD display, both in terms of size and technology.


iPhone 15

  • A16 Bionic Chip
  • 6-core CPU
  • 6-core GPU
  • 20-core Neural Engine

iPhone 8

  • A11 Bionic Chip
  • 6-core CPU
  • 3-core GPU
  • No dedicated Neural Engine

The performance difference between the two models is quite stark. The iPhone 15’s A16 Bionic chip and 20-core Neural Engine provide a vastly more powerful and efficient user experience than the iPhone 8’s A11 Bionic chip.


iPhone 15

  • Dual-Lens Setup with LiDAR
  • Advanced Computational Photography
  • ProRAW and ProRes Video Recording

iPhone 8

  • Single 12MP Lens
  • Basic Computational Photography
  • 4K Video Recording at 60fps

Camera technology has advanced significantly since the iPhone 8, and the iPhone 15’s dual-lens setup, coupled with LiDAR and advanced computational photography, offers far superior photo and video capabilities.

Battery Life

The iPhone 15 outperforms the iPhone 8 in battery life thanks to a more efficient chipset and battery optimization software.
