2. 📸 Camera: The $\mathbf{48\text{MP}}$ Game-Changer
The iPhone $\mathbf{15}$ brought a $\mathbf{48\text{MP}}$ main camera—a feature once exclusive to the Pro line—to the base model (Source 1.3). This single upgrade is the $\mathbf{15}$'s strongest argument for current relevance.
2.1. Photo Quality That Rivals Flagships
- $\mathbf{48\text{MP}}$ Main Sensor: The main camera ($\mathbf{f/1.6}$) uses Quad-Pixel technology to capture stunning $\mathbf{24\text{MP}}$ default images (Source 1.4). In good daylight and even moderate low light, the photos are vibrant, detail-rich, and virtually indistinguishable from the $\mathbf{17}$ (Source 2.1). The $\mathbf{2\times}$ $\text{optical-quality}$ zoom—a high-quality crop from the center of the $\mathbf{48\text{MP}}$ sensor—is perfect for portraits and is a huge feature the older base models lacked (Source 1.4).
- Computational Photography: Features like $\text{Photonic Engine}$, $\text{Deep Fusion}$, and the latest $\text{Smart HDR}$ algorithms are all handled flawlessly by the $\text{A16}$'s advanced $\text{ISP}$ (Image Signal Processor), ensuring professional-grade processing (Source 1.4, 3.1).
2.2. The Upgrade Trade-Offs
Choosing the $\mathbf{15}$ means missing some camera luxuries found in the $\mathbf{17}$ (Source 2.1):

| Front Camera | $\mathbf{12\text{MP}}$ (Fixed Focus) | $\mathbf{18\text{MP}}$ $\text{Center Stage}$ (Autofocus) |
| Camera Control Button | No (Traditional Silent Switch) | Yes |
While the $\mathbf{17}$’s $\mathbf{48\text{MP}}$ Ultra Wide is a technical improvement, most users take the majority of their photos with the main lens, where the $\mathbf{15}$ excels (Source 2.1, 4.2). The fixed-focus $\mathbf{12\text{MP}}$ front camera is a small sacrifice for a significantly lower cost.
3. đź’ľ The $\mathbf{256\text{GB}}$ Sweet Spot: Value and Peace of Mind
The choice of storage is where the $\mathbf{15}$ truly shines as an affordable choice.
3.1. Why $\mathbf{256\text{GB}}$ is the Baseline Today
