2. Screen: High Quality OLED Technology

The iPhone 12 is the first "classic" iPhone (excluding Pro models) to benefit from a Super Retina XDR OLED screen, offering:

Excellent image quality with infinite contrast.
HDR10 and Dolby Vision for a better video experience.
Max brightness: 625 nits (standard), 1200 nits (HDR).

📌 But…
❌ No 120 Hz , unlike the Pro models and the iPhone 13 Pro and 14 Pro.

💡 Verdict: A superb screen , but limited to 60 Hz for fluidity.


3. Performance: The A14 Bionic Chip Is Always Fast

The iPhone 12 is equipped with the A14 Bionic chip , engraved in 5 nm , which was at its launch the most powerful on the market .

🚀 Advantages of the A14 Bionic:
Very fast for all tasks (gaming, multitasking, video editing).
Optimized for iOS 18 and probably up to iOS 20 (2026-2027).
Good energy management to preserve autonomy.

📌 But…
Less powerful than the A15 (iPhone 13) and A16 (iPhone 14).

💡 Verdict: The iPhone 12 remains very capable in 2025 , but an iPhone 13 or 14 will be a better choice for longevity.


4. Camera: A Versatile Dual Sensor

The iPhone 12 features a dual 12MP camera , similar to the iPhone 11 but with better software processing .

📸 Main features:
Wide-angle (12 MP, f/1.6) → Brighter than iPhone 11, improves low-light photos.
Ultra wide-angle (12 MP, f/2.4, 120°) → Ideal for landscapes and group photos.
Night Mode and Deep Fusion for better low-light performance.
4K HDR Dolby Vision video , with more dynamic colors.

📌 But…
No optical zoom (unlike Pro models).
Night Mode less effective than on iPhone 13 and 14 .

💡 Verdict: Very good camera , but less powerful than recent models , especially in Night mode.


5. Autonomy: Sufficient, But Lacking

🔋 Battery capacity: 2815 mAh
📌 Average autonomy:

  • Normal useUp to 15 hours .
  • Video streamingAbout 10-11 hours .
  • Games and intensive use5-6 hours .

📌 Comparison with other models:

Model Battery Autonomy (typical use)
iPhone 12 2815 mAh 1 day
iPhone 13 3240 mAh 1.5 days ✅✅
iPhone 14 3,279 mAh 1.5 days ✅✅
iPhone 15 3,349 mAh 1.5 - 2 days ✅✅✅

📌 Known issue:
❌ Battery that wears out faster than on the following models (lower capacity).

💡 Verdict: Decent battery life, but inferior to newer models . A battery replacement may be a good option.


6. Connectivity and Technology

📡 Connectivity:
5G (first compatible iPhone).
Wi-Fi 6 for a faster connection.
Bluetooth 5.0 and NFC for Apple Pay and accessories.

🔌 Top-up:
20W fast charge (50% in 30 min) .
MagSafe (15W) and Qi (7.5W) wireless charging .

📌 But…
No USB-C → Always Lightning.
No Wi-Fi 6E or Bluetooth 5.3 (present on recent models).

💡 Verdict: Still very modern , but Lightning is starting to look outdated .


7. Conclusion: Is the iPhone 12 Still Interesting in 2025?

🔹 Screen → ✅ Excellent OLED, but limited to 60 Hz .
🔹 Performance → ✅ A14 Bionic still fast, but inferior to newer models .
🔹 Photo → ✅ Good, but not at the level of the iPhone 13/14/15 .
🔹 Battery life → ❌ Lower than iPhone 13, 14 and 15 .
🔹 Charging port → ❌ Always Lightning (no USB-C) .

🥇 Final Verdict: The iPhone 12 is still a good choice in 2025, but…

If you find it in good condition and at a price below €350, it is a decent option.
If you want better battery life and an improved camera, the iPhone 13 or 14 is a better choice.
