Should I choose iPhone 4 or iPhone 17?

Verdict: Choose the iPhone 17 first for any real-world, modern smartphone use case across performance, communication, photography, and software support.

The iPhone 17 is the definitive choice for virtually every user, vastly outperforming the legacy iPhone 4 across processing, display, camera technology, and modern connectivity.

The iPhone 17 completely surpasses the iPhone 4 across every technical metric, trading the iPhone 4's 1.0 GHz single-core 32-bit A4 chip and 512 MB RAM for an A19 processor equipped with a 16-core Neural Engine. For visual clarity and media consumption, the iPhone 17's 6.3-inch 120Hz ProMotion OLED panel reaches up to 3,000 nits peak brightness, far exceeding the iPhone 4's 3.5-inch 60Hz LCD maxing out at 500 nits and a 960x640 resolution. Photography sees an exponential upgrade from a single 5 MP rear camera and VGA front sensor to dual 48 MP Fusion shooters and an 18 MP Center Stage camera. Furthermore, the iPhone 17 delivers modern 5G and Wi-Fi 7 connectivity over USB-C alongside an IP68 submersion rating up to 6 meters for 30 minutes, whereas the iPhone 4 remains constrained to 7.2 Mbps 3G networks, a legacy 30-pin dock connector, unrated water resistance, and an 8 GB base capacity versus the iPhone 17's 256 GB baseline.
