Despite its age, the iPhone 12’s A14 Bionic chip continues to impress in benchmarks and real-world usage:

Camera Performance: Still Competitive in 2025?
The iPhone 12’s dual-camera system remains a standout feature, offering versatility and quality that rival newer budget and mid-range smartphones:
- Wide and Ultrawide Lenses: The 12MP wide lens (f/1.6) excels in low-light conditions thanks to Night Mode, while the ultrawide lens (f/2.4) captures expansive landscapes and group shots with minimal distortion.
