4. Operating system
With a wealth of potent features and an emphasis on privacy protection, iOS is the most private and secure mobile operating system available. All the models in the iPhone 15 lineup feature the newly introduced iOS 17 operating system. Here are a few things to know about that:

5. External buttons
External buttons on the iPhone 15 and iPhone 15 Plus include the volume up and down buttons, the ring/silent button, and the side button for locking or powering off the phone.

External buttons on the iPhone 15 Pro and iPhone 15 Pro Max are slightly altered, which is introduced with these models. While they still include the volume up and down buttons and the side button for locking or powering off the phone, their third button is slightly different. What was the ring/silent button previously is now the ‘action’ button (only for 15 Pro and 15 Pro Max). This means that instead of only the ring/silent function, that button can now have various functions, which the user can set. These functions include switching between the ring and silent modes, setting a focus mode, launching the Camera app, turning on and off the flashlight, launching the Voice Memo app, launching the Translate app, launching the Magnifier app, and running a shortcut.

6. Charging port
With the new iPhone 15 lineup, Apple introduced a charging port. Instead of the Lightning port, all the iPhone 15s now have a USB-C port for charging and data transfer. Further, the iPhone 15 and iPhone 15 Pro support only USB 2 transfer speed, up to 480 Mbps, and the iPhone 15 Pro and iPhone 15 Pro Max support USB 3 transfer speed, up to 10 Gbps.
