2. ✨ Design, display, and ports: USB‑C vs Lightning
· The iPhone 14 Pro uses stainless steel, making it heavier but giving a premium feel, whereas the iPhone 15 is lighter and offers a more comfortable grip.
· Port: The iPhone 14 Pro uses a Lightning port, but by 2026 USB‑C is standard, making the iPhone 15’s USB‑C more convenient. However, the iPhone 15’s USB‑C operates at USB 2.0 speeds, so data transfer is the same as Lightning.
· Display: The iPhone 14 Pro features a 120 Hz ProMotion display that supports smooth animations and an Always‑On Display. The iPhone 15 uses a 60 Hz display, which is considered outdated technology as of 2026.

3. 💻 Software updates, iOS 26 and Apple Intelligence compatibility
· Both devices run the latest iOS 26 smoothly, allowing you to experience the new 'Liquid Glass' design language and an improved user interface.
· Apple guarantees at least five years of OS updates, so a three‑year‑old iPhone 14 Pro still receives the same OS experience as the newest iPhone.
· Apple Intelligence: The iPhone 14 Pro and iPhone 15 do not meet the 8 GB RAM requirement, so they do not support Apple Intelligence. However, external AI apps like Gemini or ChatGPT are more powerful, so it isn’t a major drawback.
