The iPhone 15 boasts a powerhouse A16 Bionic chip1, promising smoother performance, improved graphics rendering, and with incredible efficiency for exceptional battery life. It powers all kinds of advanced features like computational photography used for 24MP photos and next-generation portraits, Voice Isolation for phone calls, and smooth performance for graphics-intensive games. Storage options range from 128GB to 512GB, catering to all your data needs.

The Super Retina XDR OLED display delivers exceptional visuals with vibrant colors and deep blacks. The display2 is great for watching content, streaming movies, and playing games.

Peak HDR brightness now reaches up to 1600 nits so HDR photos and videos look better than ever. And when it is sunny, peak outdoor brightness reaches up to 2000 nits — twice as bright as the previous generation.

The camera system received a significant upgrade. It features a new 48MP main sensor that shoots sharp photos and videos while capturing fine details and advanced image processing capabilities. It shoots in super-high resolution so it’s easier than ever to take standout photos with amazing detail — from snapshots to stunning landscapes. If you want to quickly capture the moment before it’s gone, you no longer have to switch to Portrait mode. If your subject is a person, dog, or cat, iPhone 15 automatically captures depth information so you can choose to instantly see your photo as a portrait, with an artful blur effect or later in the Photos app.

The design is expected to remain sleek and sophisticated, with potential refinements like a thinner profile or a new color option. It features back glass that has color infused throughout the material. A custom dual ion-exchange process for the glass, and aerospace-grade aluminum enclosure, help make this device incredibly durable. The enclosure of the phone also has 75% recycled aluminum which minimizes environmental impact. It’s also a relief that the iPhone 15 is splash, water, and dust resistant.3

The Dynamic Island bubbles up alerts and Live Activities — so you don’t miss them while you’re doing something else. You can control your music, see who’s calling, check your flight status, and so much more. The Ceramic Shield front is tougher than any smartphone glass. For all the things you want to keep doing, the iPhone 15 has an All-day battery life of up to 20 hours of video playback.4

The device now comes with a USB-C connector that lets you charge your Mac or iPad with the same cable you use to charge the phone. You can even use the iPhone 15 to charge Apple Watch or AirPods.5

The iPhone 15 isn't just an evolution, it's a revolution in your pocket. | Good Guy Gadgets

The iPhone 15 isn’t just an evolution, it’s a revolution in your pocket. It’s the camera that captures your world in a way you never thought possible, the performance that lets you achieve more on the level of consistency compared to top entry level premium Android devices, and the design that turns heads wherever you go.

Whether you’re a photography enthusiast, a productivity seeker, or simply someone who wants the latest and greatest, it deserves a serious look.


  1. While the iPhone 15 gets the older A16 Bionic chip currently powering the iPhone 14 Pro and Pro Max handsets, the fast and efficient chip still brings proven performance to iPhone 15 and iPhone 15 Plus, powering the Dynamic Island, computational photography capabilities, and more.
  2. Display size: The display has rounded corners that follow a beautiful curved design, and these corners are within a standard rectangle. When measured as a standard rectangular shape, the screen is 6.12 inches (iPhone 15) or 6.69 inches (iPhone 15 Plus) diagonally. Actual viewable area is less.
  3. iPhone 15 and iPhone 15 Plus are splash, water, and dust resistant and were tested under controlled laboratory conditions with a rating of IP68 under IEC standard 60529 (maximum depth of 6 meters up to 30 minutes). Splash, water, and dust resistance are not permanent conditions. Resistance might decrease as a result of normal wear. Do not attempt to charge a wet iPhone; refer to the user guide for cleaning and drying instructions. Liquid damage not covered under warranty.
  4. All battery claims depend on network configuration and many other factors; actual results will vary. Battery has limited recharge cycles and may eventually need to be replaced. Battery life and charge cycles vary by use and settings. See and for more information.
  5. The included USB‑C Charge Cable is compatible with AirPods Pro (2nd generation) with MagSafe Charging Case (USB‑C).
